After googling this topic and finding nothing, I figured XDA was the place to go. I am looking for a way to get a C++ compiler working on my phone (mytouch slide) or android in general.
Thanks in advance
Que? Like a C++ compiler to compile for android? Why would u want this C++ don't run native on Android it must be called from java so it would be pointless.
There is an sdl port around that required zero knowledge of.java but I believe it still has to compile the java each time. If not it could be possible...

I don't want to run the programs on my phone, just compile
Compile for what?
What is the Android NDK?
The Android NDK is a toolset that lets you embed components that make use of native code in your Android applications.
Android applications run in the Dalvik virtual machine. The NDK allows you to implement parts of your applications using native-code languages such as C and C++. This can provide benefits to certain classes of applications, in the form of reuse of existing code and in some cases increased speed.
The NDK provides:
* A set of tools and build files used to generate native code libraries from C and C++ sources
* A way to embed the corresponding native libraries into an application package file (.apk) that can be deployed on Android devices
* A set of native system headers and libraries that will be supported in all future versions of the Android platform, starting from Android 1.5
* Documentation, samples, and tutorials
The latest release of the NDK supports these ARM instruction sets:
* ARMv5TE (including Thumb-1 instructions)
* ARMv7-A (including Thumb-2 and VFPv3-D16 instructions, with optional support for NEON/VFPv3-D32 instructions)
Future releases of the NDK will also support:
* x86 instructions (see CPU-ARCH-ABIS.TXT for more information)
ARMv5TE machine code will run on all ARM-based Android devices. ARMv7-A will run only on devices such as the Verizon Droid or Google Nexus One that have a compatible CPU. The main difference between the two instruction sets is that ARMv7-A supports hardware FPU, Thumb-2, and NEON instructions. You can target either or both of the instruction sets — ARMv5TE is the default, but switching to ARMv7-A is as easy as adding a single line to the application's Application.mk file, without needing to change anything else in the file. You can also build for both architectures at the same time and have everything stored in the final .apk. For complete information is provided in the CPU-ARCH-ABIS.TXT in the NDK package.
The NDK provides stable headers for libc (the C library), libm (the Math library), OpenGL ES (3D graphics library), the JNI interface, and other libraries, as listed in the section below.
The NDK will not benefit most applications. As a developer, you will need to balance its benefits against its drawbacks; notably, using native code does not result in an automatic performance increase, but does always increase application complexity. Typical good candidates for the NDK are self-contained, CPU-intensive operations that don't allocate much memory, such as signal processing, physics simulation, and so on. Simply re-coding a method to run in C usually does not result in a large performance increase. The NDK can, however, can be an effective way to reuse a large corpus of existing C/C++ code.
Please note that the NDK does not enable you to develop native-only applications. Android's primary runtime remains the Dalvik virtual machine.
The ndk allows u to use c++ c/c++ code in Android. That code must be called from java tho.

I don't think you guys are understanding his question... He's not looking to write apps for Android... he's writing stuff in C++ (presumably for desktop or maybe other embedded applications, I dunno) and just wants to be able to compile that code on his Android device...
Now as far as an answer to that question, they did kinda cover it... Since pretty much everything in Android runs in Java, I believe it would be pretty difficult to write a C++ compiler that could run on Android.
To install an compiler in your Android device, google around for how to install Debian in it. Don't be afraid, you install it in parallel of Android, you will need a command or terminal window as well (available in the marketplace).
Debian comes with everything you need to compile in your device.
I hope I was useful.
Cheers
Thank you abrigham for clearing that up for me. You are exactly correct.
Ernestus, that seems like it would cause more problems then it would be worth
hmm.. i was googling for this as well.. thought it'll be useful to have this around.

Next best option then is to cross-compile to Android/ARM from another platform. The arm-eabi toolchain provided by Google's NDK is one option as others have already mentioned.
Codesourcery ARM toolchain is another, for Linux i686 theres link to the downloadable archive see this post (search for 'wget THISLINK' text on that page).

If your looking to corss compile for android, check this link out.

Installing debian isn't too bad, and would give you the most flexibility for compiling on the phone.
You could also ssh into another computer using connectbot or some other terminal and code/compile remotely.
Another way to do remote compiles is continuous integration. Edit/upload the file to your repository, and using a server such as Jenkins, run the compile and view the results through the browser or an app such as Hudson2Go. Jenkins will also auto-compile on edits and can send you a text if the build fails. Jenkins is very easy to setup.
Try finding an online c++ compiler or you could connect to a windows or linux machine/server to upload andcompile your c++ files.

Use "c4droid" this is a paid app.. anywy if you like search on the market.
Another alternitiv is out there now. Not sure how good it works.
C / C++ Compiler
im looking for compiler too i found i market a4droid compiler but it costs... and i couldnt find enywhere free apk
Easiest thing to do would be a chroot Linux environment from an existing distribution, like Ubuntu. Then compilers for nearly any language you can think of are an "apt-get install" away.
If you're running CyanogenMod 7, you have a large SD card, and you don't mind repartitioning the SD card and shaving off 2 GB or 4 GB for Linux, then I'll be posting a howto in the next day or two. I have Ubuntu 11.10 Oneiric Ocelot running out of /sd-ext cleanly, using only files from official sources (<32 MB file from cdimage.ubuntu.com and everything else via apt/dpkg with signature verification) rather than from rapidshare-like sites.
Or about a year ago there were instructions posted for unzipping a ~2 GB image containing an older version of Ubuntu downloaded from a filesharing site. You could do that if you have an immediate need.
you can download from my blog
http://dateno1.egloos.com/855501
it from https://market.android.com/details?id=com.n0n3m4.gcc4droid&feature=more_from_developer
it has some library problem but work well (i already compile few binary for my phone )
I think c4droid maches perfectly what you were looking for. I'm using it to work on my projects "on the road" and so far it works pretty well.
A little tricky to set up, since you need "gcc plugin for c4droid" but to choose g++ compiler, and builds are saved at "data/data/com.n0n2m3.c4droid/files/temp" or something like that...
There's another option, but you still have to pay: DroidEdit Pro. Perhaps better editor (didn't test it though) but without it's own compiler, you have to set up an external compiler from sftp server.
Is there any way to compile java applications in android?
i wanna write simple java applications like i do in ms-dos
"javac file.java, java file".
could somebody tell me if i can do it?

if you want to build an app of course you can but i don`t know if that`s so simple. depends on knowledge
but you can start here:
1. http://developer.android.com/sdk/index.html
2. http://www.eclipse.org/downloads/
3. you will need java too
are you sure i do this on my mobile?
if i got it,right this is how i make application in my pc,not in my xperia!
i want that, in my android

download terminal emulator from market and you will have access to shell through phone
well u cant , cause Android doesnt have a JVM , it has a Dalvik Virtual Machine, and its optmized for mobile aplications and for the hw of the device, but u can emulate some plataform, but if u want to compile just some java code, there some solutions in the forum like install ubuntu and compile there, but an aplications native for android is a lil' hard
edit---
you can read this, is very helpfull...
http://en.wikipedia.org/wiki/Dalvik_(software) Dalvik VM
http://developer.android.com/reference/java/lang/Compiler.html Compiler API ANDROID (u can use it =) in ur aplication)
installing/emulating ubuntu just for compiling java is a bit out of my limits!
i dont want to compile any crazy program, just some easy programs.
there is not other solution, than this?
java compilation on android device
I'm looking to do likewise for various reasons.
One is I live in a tent and the droid device consumes less power than my laptop.
Two is that I'm developing a platform that moves some 'programmer space' activities to user space. Though with java the later can normally be accomplished wo authoring any source or compiling by using introspection and object serialisation (granted an android based dx is needed here) there are use levels of the platform that afford source authoring and compilation.
Having said that as far as I can tell a javac for android is in order.
Thus: openjdk.java.net/groups/compiler/README.html
One needs to verify the source's class dependencies and see if the android vm (the dalvik vm really) implements those classes. If and where not either the compiler code needs to be modified to use dalvik implemented java classes or the dalvik vm extended to accommodate the additional classes, again if any, that the javac source uses.
The determination as to which direction to take need consider the effort involved
either way and the legalities of either way while noting that the dalvik vm is allready the subject of a lawsuit (see Controversy at en.m.wikipedia.org/wiki/Dalvik_(software) ).
Personnaly I'm leaning to modify the javac source if necessary as this
openjdk.java.net/legal/
doesn't look prohibitive in so long, I think, as the language specs are met or more simply.in so long as the modified to run on android javac produces the same results as the original.
If you're ready to get yor hands dirty (not all coding is drag and drop) here ya go
download.java.net/openjdk/jdk6/
Maybe we'll meet somewhere along the way.
Sp
I got ClassCycle and ran it on the classes that resulted from me compiling the javac sources
in the openjdk's langtools directory . These sources are a programatic interface to javac and
are said to be used at one's own risk.I had trouble compiling the 'actual' sources
but will try again.
Once I can make heads or tails of the ClassCycle report I can provide a list
of javac's class deps.
Why one might ask would is any of this class deps stuff needed?
Dx the Java bytecod+e and run it. Droid has a vm, should be ok.
The problem is that Dalvik, at least does not implment awt and swing. What this means is that there is no native implementation for those classes' bytecode to be runtime instantiated towards.
Likewise if there are javac class deps that the dalvik vm does not implement there will be no native implementation in those areas and the bytecode won't run.
Till I get the list,
Steve

For rooted systems there is a way to run Ubuntu in the phone/tablet. I don't remember the details, just google for it. I only remember that you should use a VNC viewer to connect to the xserver running in your own system.
I don't know if you can access from that Ubuntu to the resources of your Android (sensors, GPS, camera, and so on).
If you want to be able to create small programs in an easy way for your Android and being able to access all sensors and peripherals of your phone you should consider using SL4A (Script Layer for Android).
It's a base scripting system. On top of it you can install Python, PHP, Bash. So you can write your own scripts using any text editor in the phone, and run it without using any computer in the process

Changelog
ArchiDroid 2.4.3
- Improved archidroid_pixelserv
# Previously archidroid_pixelserv responded to all requests with the same 1x1 NULLGIF response (GIF89a[]![])
# This was OK but in some apps it showed our gif in binary form (GIF89a[]![]) instead of showing nothing, i.e. in Subway Surfers game
# Now we respond with a "NULL" content proper for request
# If app requests JPG, we respond with NULLJPG, if app requests TEXT, we respond with NULLTEXT etc.
# This way app "gets what it wants" and won't show something, which it can't understand to user
# Surprisingly, at least Subway Surfers doesn't show any ad right now, so it also stops some apps from displaying NULL content, instead of showing NULL in binary form
- Removed VNC Viewer
- Updated ArchiDroid Backend tools (dnsmasq, haveged, dnsproxy2, pixelserv) to latest versions
- Updated PA GAPPS to 0417
- Used Carbon as base; Omni is maybe coming in future (if requested; this eventually needs much time)

First of all, ArchiDroid includes everything available in it's base. The whole point of ArchiDroid is to improve the base, without needing of making any trade-offs, so by flashing ArchiDroid, you're getting everything offered by the base itself. There's nothing to lose, everything to gain.
You can read detailed information about every ArchiDroid component here. It's a massive wall of text, so I'm only going to list the core features without describing them.
These were written from scratch, they're completely unique and you won't find exactly the same implementation in any other ROM.
ArchiDroid-Unique features:
- ArchiDroid's AROMA Installer
- ArchiDroid's Pocket Debian
- ArchiDroid's Flasher
- ArchiDroid's RunOnce
- ArchiDroid's Init
- ArchiDroid's Backend Control
- ArchiDroid's HArdware Volatile Entropy Gathering and Expansion Daemon (Haveged)
- ArchiDroid's Fast Random Number Generator (Frandom)
- ArchiDroid's Adblock (dnsmasq/dnrd, dnsproxy2, pixelserv)
- ArchiDroid's Forced Update
Apart from that, here, on the credits page, you can find all third-party projects, which have been implemented into ArchiDroid. In addition to that, it's up to YOU to decide if you want to install something, or not.
ArchiDroid focuses on flexibility and user choice.
If you're looking for fastest ROM, choose ArchiDroid.
If you're looking for most battery-saving ROM, choose ArchiDroid
If you're looking for cutting-edge functions, choose ArchiDroid
If you're looking for the most flexible rom ever created, definitely choose ArchiDroid
ArchiDroid adjusts to your needs. You can make it whatever you want. With bunch of presets, modes and questions, you can make your ArchiDroid behave. Check yourself why ArchiDroid is The TOP 1 ROM for Galaxy S3http://forum.xda-developers.com/galaxy-s3#romList, according to number of followers, rates, reviews and downloads count. Check the Reviews, take a look at Video Reviews, do whatever you want to, ArchiDroid is proven to be one of the best ROMs for Galaxy S3, ever created.
Try ArchiDroid once, and you'll never look back. I can assure you.

Especially:
ArchiDroid is one of the most complex ROMs ever created. When you start digging in my work, you can very easily get lost. And I'm not talking about base itself, but about everything next to it. You can use every part of my work, as long as:
1. You include proper credit where you should. This usually includes proper comment in a script/file and in the credits of the project, including license (if needed)
2. You let me know about this fact. Through PM on xda or e-mail
I'm always happy to help, especially with the problems I faced in the past. However I also want to be respected, considering that most of the ArchiDroid parts were written from scratch.
Know Your ArchiDroid
ArchiDroid is not only a rom. It's not only a baked android with third-party apps, modifications and tweaks. ArchiDroid is an universal backend which improves rom by many built-in functions.
Let me tell you a story. During developing first version of ArchiDroid 2.0 I experienced many problems, which were not that easy to solve. First of all - apps data. Trust me or not but you can't simply extract data, put it in /data/data after install and hope that it works. Android will detect such injection, report inconsistent of data and wipe everything attached to that. Okay so... How I should provide you with my boeffla preset? CoolTool settings? STweaks profile? If I put my data during flashing it'll get wiped. If I put my data and deny wiping it then Android will report inconsistent of data to user and work unstable. Yes guys, it's impossible to do so without a trick or without recompiling whole rom.
I won't tell you a whole story, because you probably don't want to hear about ArchiDroid development. I'll simply tell you that I overcome MANY difficulties, simply because I do what I like, and I like what I do. After countless number of hours, I can finally provide you with the ROM, which is the best. Why is it the best? Because I'm improving the base, and I'm not making any trade-offs.
GitHub / Versioning / Experimental Versions
You can easily "pack" latest experimental and flash without needing to wait for the next build. I'll tell you how to download and flash it by yourself.
[Newbie Version]
1. Open 2.X-EXPERIMENTAL branch.
2. Click on Download Zip button located in bottom-right corner.
3. Install 7-Zip if you don't have that already. Other programs may, or may not work correctly.
4. Right-Click on zip, select Extract Here
5. Navigate to newly created ArchiDroid-2.X-EXPERIMENTAL folder
6. Select all files WITHOUT __dont_include folder, right-click and select 7-Zip => Add to archive
7. Make sure that you have zip format, Fastest compression (to save some megabytes) and Deflate method of compression.
8. Voila, copy newly created ArchiDroid-2.X-EXPERIMENTAL.zip to your phone and flash as usual.
[Expert Version]
1. Install Git for Windows or Linux
2. If you're on windows then make sure that windows won't change LF into CRLF (git config --global core.autocrlf false)
3. Clone my git repository using .git file. Keep in mind to specify depth, as this repo is really big. (git clone https://github.com/andreasltcf/ArchiDroid.git --branch 2.X-EXPERIMENTAL --depth 1)
4. Select all files WITHOUT __dont_include folder zip them into standard .zip format with Deflate compression or without any compression.
5. Copy .zip to your phone and flash as usual
6. In order to update your local repo execute git pull origin 2.X-EXPERIMENTAL and go to point 4.
Additionally you can watch @JustArchi's short video, which shows how to flash experimental ArchiDroid going through "Expert Version" (Archi's GitHub).
ArchiDroid Features
Know your ArchiDroid, learn how to use it
Introduction / Basics
Welcome to ArchiDroid's world mortal. In this tutorial we will show you what ArchiDroid has "inside" and what it really offers. All of things included in this post are ArchiDroid-specific, which means that you won't find any ROM with the same features, as they're written from scratch.
Here you can find some definitions of the words used in sections below. You should know most of them, but in case somebody is lost here you can get back on track.
Terminal, Shell - Typical android shell, which may be obtained in three ways.
1. Through native Android Debug Bridge (ADB) with command "adb shell" from the PC or even "ADB through network" (if supported).
2. Through any Android terminal app, f.e. Android Terminal Emulator bundled with ArchiDroid.
3. Through secure shell daemon (sshd), which needs to be turned on firstly. This is extremely useful in terms of pocket debian, which will be described later.
You can use any of these methods to access android's terminal, however usually Android Terminal Emulator will be the easiest one, as it's android app bundled with ArchiDroid. WARNING! Most of the commands below WILL require root access. You can log in to super user shell by "su" command right after obtaining shell. If you're unsure if you're logged as root or not, "whoami" command should print actual user, "root" or "unknown uid 0" are OK, others are not.
ArchiDroid's Pocket Debian
From wikipedia:
From debian site:
How exactly this covers our beloved SGS3 (and countless number of other android arm-based phones)?
As you may (or even should!) know, Android operates on it's own Linux-based kernel. Android's kernel is literally a fork of Linux kernel, with a few special/unique functions which are required, mostly hardware-specific. Because of that kernel itself is VERY compatible with everything based on Linux.
However there have always existed one typical problem, lack of proper environment. We have a great kernel, great power, linux-based android environment, but this environment lacks of very common and required libraries/binaries. If you ever wondered what is or what does busybox, this is the answer. Busybox is just a small package which offers a few standalone GNU/Linux binaries, which are required to make certain things work. For example, swap priorities. Android knows what swap is, and nothing else. It doesn't know that swap could have a priority, so if you use android's swapon command on 4 devices, it will firstly fill first device, and then proceed to the next. That's why we need busybox in ALL custom kernels, because android environment isn't enough.
However busybox sometimes isn't enough. If we focus only on Android itself, it is. But if you for example want to run stricly linux-based service, I don't know, a web server for example... Is it possible to run a native linux web server on an android? No, it's not. You should firstly compile such service on arm architecture, including all dynamic and static libraries (wrrr ) in it only to finally get mad because of missing libraries or other dependencies. Of course if you're patient you'd finally compile everything and set up, however how long would it take? A few days maybe? If you're skilled in what you're doing...
This is why I included built-in "pocket" debian in ArchiDroid. It's FULLY compatible with everything compiled/based on armhf/armel GNU/Linux architecture, for example Raspberry Pi. With two easy commands you can literally jump into debian environment and use every typical GNU/Linux utilities known from debian itself. Of course this means nothing for most of the users, because they'll never have any reason to use such debian environment but from the developer side, it's big step forward. The best example is with github. As you know ArchiDroid has it's own repo on github, from where you can download/manage stuff. There also exists git app for linux and windows. If you want to follow "expert" way of flashing experimental ArchiDroid version, such program is required. The scenario is the same as compiling web server for an android, it requires much more effort than it's worth. And even then you can end up with syncing external dependencies and searching for solutions for the problems you've never seen before... And with ArchiDroid's pocket debian? It's as simple as in any debian/ubuntu distro. "apt-get update && apt-get install git" and voila. Your git is installed and ready for work. Going further I've even included git in pocket debian itself. Okay, I have debian, I have git, and what next? With git utility I can for example provide you with delta updates for ArchiDroid! ArchiDroid can easily use pocket debian to set up and sync ArchiDroid's repository and then pack and flash latest version without even needing of a PC, using 7-zip or anything else. Another example? A web server. I know that it's very dev-specific but if you for any reason need a web server running, just for example to test simple website, you can have it with just one command. Going further, VNC? MySQL server? PHP? Python? Perl? Ruby? Maybe conditional tasks with cron? Persistent minimal IRC client? rtorrent with rutorrent GUI over WWW? The list goes on... Anything based on linux will work. You can even host a server for your favourite game, as long as it has armhf/armel binaries (unfortunately most of the games don't).
So that's it. In short, debian is an operating system built-in in ArchiDroid to provide you with (unfortunately missing) GNU/Linux environment, with full power, ready to handle anything you could request. I made my best to include fully working debian in ArchiDroid for a minimal cost. Whole OS is packed in one big tar file, compressed using highest bzip2. As for now pocket debian has ONLY 40 megabytes of size, maybe in future it will have up to 50 megabytes, but no more. It's a VERY small cost for having such great power, especially if you know how to use it.
This is a really cutting-edge feature, mostly because I have no limitiations what I can include in my ROM right now, and while other developers are dealing with OpenDelta updates and many Android-based problems, I'm just launching my pocket debian and manages linux stuff.
I'm SURE that most of the advanced ArchiDroid user will just LOVE this feature, as much as I love it. I'm looking forward to your responses how YOU use pocket debian with your ArchiDroid. It's also a great time to learn what does the debian offer and how you can simplify your common tasks with just one example debian utility .
Technical informations:
1. Pocket Debian does not cause any additional overhead. We don't need to use emulation, neither virtualization to boot our monster. I used chroot technology to "jump" into debian environment with already running kernel and Android. That means additional required CPU/RAM is based on what you run in pocket debian. Booting itself doesn't require anything, just about one megabyte of ram for /bin/bash shell .
2. Android has some restrictions, mostly sockets. It doesn't allow to create inet sockets by default, even for root users. You will need to add your custom debian users to special group called "inet" (GID 3003) to allow creating of inet sockets, and you may also need to add a group to net_raw group (GID 3004) to allow creating of raw sockets. Please keep in mind that it's only required if you're running an app which required it's own socket, for example mysql server. So apt-get install mysql-server will fail right after booting, you will need to use "addgroup mysql inet" and then apt-get -f install to complete installation. Of course "mysql" is the new user under which mysql-server really operates. I've added root to both of these groups by default.
3. The only "real" restriction is the kernel. Our debian uses Android kernel and it's filesystem. It should work with most common tasks but in some cases our kernel may lack specific modules or built-in code, for example tun/tap required for OpenVPN. Still it's enough to run pretty much everything and if you get in touch with your favourite kernel developer you can also kindly ask for specific missing things.
4. Debian is built and included thanks to debootstrap utility, ArchiDroid command used for creating debian environment is debootstrap --verbose --arch armhf --include=git,ca-certificates,ssh,htop,tightvncserver,xterm,xfonts-base --exclude=manpages,man-db,rsyslog,vim-common,vim-tiny testing debian http://ftp.fr.debian.org/debian
HowTo:
Pocket Debian contains two main terminal commands, "adlinux" and "debian". Both of them are described below. By adlinux and debian you boot and jump into debian's chroot, which means you can use any debian-specific commands.
Examples:
passwd - changes password of actual user. This is needed to login as specific user, for example through ssh.
service ssh start - starts local SSH (secure shell) daemon on native port :22, to which you can easily access via any client supporting ssh, f.e. PuTTY. So basicly after you start shell you can literally connect to your local area network (LAN) IP on port 22 f.e. through PuTTY from your PC.
ifconfig - prints network-related informations about online interfaces, including your local IP, which may be useful for connecting to SSH.
htop - Enhanced top utility. Gives you very good terminal-based view on actual running processes, used ram, load, and more.
apt-get update - Syncs with debian's apt repository. This is mandatory to use many of apt commands because ArchiDroid's debian comes without local repo available, however fully configured to download and access it with just one command
apt-get install XXX - installs packet XXX from debian's repository.
apt-cache search XXX - searches for all packets including keyword "XXX". Ultra useful in terms of searching for specific packet.
Please note that pocket debian is VERY similar to normal native Debian/Ubuntu distribution, therefore above commands are not ArchiDroid's magic, they're very widely used in Debian/Ubuntu distros. If you want to learn more, most of the Debian/Ubuntu tutorials will be very helpful.
ArchiDroid's Pocket Debian Booter (adlinux)
You can call "adlinux" command from your favourite terminal.
adlinux is designed to boot and prepare ArchiDroid's Pocket Debian environment. It requires mode to be specified, and also respects any extra arguments passed.
If you call standalone "adlinux" command then it will print usage and then ask you what you want to do with giving proper informations about every choice. Additionally if you know what you want to do, you can also pass arguments directly to adlinux command, f.e. by executing "adlinux default", which will execute adlinux with "default" mode.
Available modes:
default - Will mount /data /system /storage/sdcard0 /storage/sdcard1 and core filesystems in chroot. Default suggested mode
safe - Will mount only core filesystems in chroot. Useful if you don't want to share your storage in chroot
bare - Won't mount even core filesystems such as /proc /dev or /sys. Requires "debian force" to enter chroot. This is the "real" safe mode. You won't be able to interact with an android in any way, while debian itself will work in very limited environment, making core functions unavailable. Suggested only for testing purposes
rebuild - Will automatically reboot your device and remove debian folder in the safe way. WILL CAUSE ALL DEBIAN DATA TO BE LOST!
unmount - Will automatically reboot your device to safely unmount debian environment
Extra options:
extsd - Use external sd card (/storage/sdcard1 /storage/extSdCard), if possible
intsd - Use internal sd card (/data/media/0)
Additional information about modes:
Debian shares core kernel filesystems in "safe" and "default" modes, while it also shares your internal and external sd card in "default" mode. This is nothing to be scared of, as you have full control of what you run in debian, however please note that you CAN'T do whatever you want. All mounted partitions in debian are "binded". "Bind" means that it's mirrored to the mount point and all changes on mounted partition WILL affect the mount point, which is logical. This is nothing to be scared of, as long as you know that debian only extends your environment, it does not fully works in it's own and you CAN cause serious problems from inside of chroot. The only really safe mode is "bare" mode, however in "bare" mode debian can't really do anything, as kernel filesystems are absolutely required for most of the functions. Okay so, you need to know one thing. If you have booted debian you SHOULD NOT touch debian's folder, which is ArchiDroid/debian (on your internal or external sd card, depends what you choosed).. As you know debian for example binds /data to it's folder /data, which is physically ArchiDroid/debian/data. If you for example delete ArchiDroid/debian through root explorer WITH mounted debian then it will ALSO delete debian/data folder, which is binded to /data, and therefore will delete your whole internal sd card, that's why it's extremely important to take care because booted debian becomes part of the android and deleting it can cause at least soft bricks, with a possibility of hard as well. If you want to delete debian folder PLEASE use "rebuild" mode, only through this way you're absolutely sure that nothing bad happens and you won't delete your whole system partition by accident.
Note about extsd option:
Debian requires symlink functionality, typically native windows filesystems DON'T support symlinks, therefore you need to have your external sd card formatted in one of the native linux filesystems, f.e. ext4. adlinux will automatically tell you if debian can be unpacked and used on your external sd card, however it won't be possible under most common filesystems, such as exFAT or FAT32.
Technical informations:
1. Pocket debian archive is located in ArchiDroid/System/debian.tar.gz file. This is "bare" system used for creating environment for the first time, you should not touch it.
2. adlinux detects if debian is already extracted when booting, if not, it's firstly extracted from the file described above.
3. After extracting (if required), core filesystems are mounted with "bind" option based on the mode you've selected in "mode" question above. Typically it mounts /data /system /storage/sdcard0 /storage/sdcard1 /storage/extSdCard /dev /proc /sys.
4. Unmounting is not fully supported right now (linux barrier), therefore both "unmount" and "rebuild" options require a restart to execute properly.
ArchiDroid's Pocket Debian Shell/Chroot (debian)
You can call "debian" command from your favourite terminal.
debian command is designed to allow you "jumping" into debian chroot created by adlinux. Please read how adlinux command works firstly if you haven't done that already. debian command checks if core filesystems are available (if debian is booted), and if they are then it firstly modifies required environment variables to make debian happy (such as TERM, HOME, PATH), then it changes root (chroots) into debian folder, therefore allowing you to execute everything from inside of chroot. It's very generic command, therefore standalone "debian" command won't give you a choice the way adlinux did.
Available options (parameters):
force - required for jumping into bare debian, created with "adlinux bare" command above. This skips debian checks for mounted core filesystems, normally you should avoid it at all cost, unless you know what you're doing. If core filesystems are missing then it's very likely that your debian will be disabled in more than 90%.
extsd - Use external sd card (/storage/sdcard1 /storage/extSdCard), if possible
intsd - Use internal sd card (/data/media/0)
cmd - Executes command in debian chroot
WARNING! cmd parameter will cause all further parameters to be threated as a command passed to debian, therefore you need to make sure that this is the last debian parameter which you want. For example "debian force cmd service ssh start" will skip filesystems checks and execute "service ssh start" in debian's chroot, however "debian cmd force service ssh start" will pass "force service ssh start" to debian, therefore respecting filesystems checks and passing invalid command.
This function is extremely useful for making init.d and other startup scripts. For example you can easily call "adlinux default" and then "debian cmd service ssh start" to call secure shell daemon on every boot with two easy steps.
Technical informations:
1. debian command uses chroot technology to change root of current shell to debian shell.
2. After chrooting to debian directory, /bin/bash shell is automatically called as default debian shell.
ArchiDroid's Flasher (adflash)
You can call "adflash" command from your favourite terminal.
adflash is a great small utility, which allows you to easily update your ArchiDroid to latest stable or experimental version with one easy command and delta upgrade. It utilizes ArchiDroid functions, therefore you must be running ArchiDroid to use it.
If you call standalone "adflash" command then it will print usage and then ask you what you want to do with giving proper informations about every choice. Additionally if you know what you want to do, you can also pass arguments directly to adflash command, f.e. by executing "adflash 2e git", which will execute adflash with 2.X-EXPERIMENTAL version using git mode.
Available versions:
2e - 2.X-EXPERIMENTAL
2s - 2.X-STABLE
1e - 1.X-EXPERIMENTAL
1s - 1.X-STABLE
Extra options:
git - Sets up local git repository, which gives you delta upgrades and bandwidth saving
direct - Downloads targeted branch as .zip file directly from github
clean - Cleans everything up, including local repo and tmp folder from ArchiDroid directory specified below
extsd - Use external sd card (/storage/sdcard1 /storage/extSdCard)
intsd - Use internal sd card (/data/media/0)
nozip - Shows changelog and changes only
Okay so, the most interesting option is the mode...
Direct mode is simple, fast and effective. It downloads target version (stable or experimental) from GitHub server, then it repacks downloaded zip file and makes it available for flash. You should use this mode for one-time downloads, such as once per stable version or two. The only advantage of this method is the ability to download from github (and with one command).
Git mode is complex. It uses ArchiDroid's Pocket Debian (read above) for cloning and updating local ArchiDroid repo. This gives several number of advantages, mostly for using experimental versions. Firstly, by having local ArchiDroid repo you have to download ONLY changes between your snapshot and server's snapshot, which means delta upgrades. Secondly, you have access to all commits from target branch, so you know exactly what has changed since your latest download. Again, this is extremely useful for experimental branch, as changelog may not be up-to-date. Keep in mind that git mode will require additional space on your device for keeping ArchiDroid repository, therefore you sacrifice some space for delta upgrades. This mode is extremely useful for flashing ArchiDroid often, for example daily experimental versions, because in fact you download only new commits instead of whole repo/archive.
ArchiDroid's RunOnce (Backend)
ArchiDroid's Init (Backend)
ArchiDroid's Backend Control
ArchiDroid Backend Control is a set of settings, which controls behaviour of ArchiDroid's Init. It's located in /system/archidroid/dev and contains a number of files, which are recognized by ArchiDroid's Init. You shouldn't directly touch /system/archidroid/dev, instead you can control behaviour of ArchiDroid's Backend through /system/archidroid/scripts. They can be easily executed through any script manager, f.e. Root Browser or Android Terminal Emulator. Some of the settings are also located in /system/archidroid/etc folder, mostly configurations for binaries utilized by ArchiDroid's Init.
ArchiDroid's HArdware Volatile Entropy Gathering and Expansion Daemon (Haveged)
The haveged project is an attempt to provide an easy-to-use, unpredictable random number generator based upon an adaptation of the HAVEGE algorithm. Haveged was created to remedy low-entropy conditions in the Linux random device that can occur under some workloads, especially on headless servers. Current development of haveged is directed towards improving overall reliablity and adaptability while minimizing the barriers to using haveged for other tasks.
The original HAVEGE research dates back to 2003 and much of the original haveged documentation is now quite dated. Recent work on haveged has included an effort to provide more recent information on the project and its applications.
The original research behind HAVEGE use was based upon studies of the behavior of processor caches from a hardware level. The 'Flutter' documents attempt to provide a modern view of HAVEGE at software level through the use of a diagnostic build of haveged that captures the non deterministic inputs to haveged for analysis by external tools.
ArchiDroid has built-in haveged entropy generator. It's controlable through ArchiDroid's Backend Control - ArchiDroid_Haveged_EnableDisable.sh. It's turned on in default configuration, through HAVEGED_ENABLED
ArchiDroid's Fast Random Number Generator (Frandom)
Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux' built-in /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.
ArchiDroid has built-in frandom activator. It's controlable through ArchiDroid's Backend Control - ArchiDroid_Frandom_EnableDisable.sh. It's turned on in default configuration, through FRANDOM_ENABLED.
Notice: Kernel must support frandom module to actually make use of that. Init will try to search for frandom.ko module and load it, then use /dev/erandom for both /dev/random and /dev/urandom. If your kernel supports frandom, it will work. If it doesn't, obviously this will be skipped even if you have FRANDOM_ENABLED. Check ArchiDroid Init log located in /data/media/0/ArchiDroid/Init.log to check if frandom works properly for you.
ArchiDroid's Adblock (dnsmasq/dnrd, dnsproxy2, pixelserv)
dnsproxy2 is a replacement DNS proxy for Android 4.3+
This currently allows the user to manually override the DNS server IP,
and it sets the correct UID on outbound requests so they can be filtered
via iptables / AFWall+ / DroidWall / etc.
Dnsmasq is a lightweight server designed to provide DNS, DHCP and TFTP services to a small-scale network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP for network booting of diskless machines.
Dnrd, Domain Name Relay Daemon is a caching, forwarding DNS proxy server. Most useful on vpn or dialup firewalls but it is also a nice DNS cache for minor networks and workstations.
Pixelserv is a super minimal webserver, it's one and only purpose is serving a 1x1 pixel transparent gif file. Using some creative firewalling (netfilter/iptables) rules you can redirect some webrequests (for adds for example) to pixelserv.
ArchiDroid has built-in Adblock. It's controlable through ArchiDroid's Backend Control:
ArchiDroid_Adblock_DnsmasqDnrdModeSwitch.sh
ArchiDroid_Adblock_EnableDisable.sh
ArchiDroid_Adblock_EnableDisableLocalDNSes.sh
ArchiDroid_Adblock_EnableDisableLocalDNSesDaemon.sh
ArchiDroid_Adblock_LockUnlockHosts.sh
ArchiDroid_Adblock_MoabAdawayHostsSwitch.sh
ArchiDroid_Adblock_Reload.sh
It's turned on in default configuration, through:
ADBLOCK_ENABLED
ADBLOCK_LOCAL_DNSES_DAEMON_ENABLED
ADBLOCK_LOCAL_DNSES_ENABLED
ADBLOCK_USE_ADAWAY_HOSTS
ADBLOCK_USE_DNSMASQ
In short. This is a very advanced and powerful solution for blocking ads through DNS queries. First of all we're forwarding all DNS traffic to localhost (127.0.0.1). Then we're handling them through local DNS server - dnsmasq (default), or dnrd (option). Our local DNS server reads blocked hostnames through special /system/archidroid/etc/hosts file, then if no record is found, it forwards DNS query to OpenDNS/Google DNS servers, or if it's found, returns 127.0.0.1 as the address. Lastly, pixelserv is providing a 1x1 NULLGIF response on local web server, so instead of big black/white screen instead of the AD, we get 1x1 transparent pixel, which usually perfectly hides ad from the app or the website.
Extra features:
1. You can specify if you want to use dnsmasq (default), or dnrd (option) as a local dns server. Dnsmasq is more flexible, modern, faster and has less memory footprint, however I also left dnrd as an option, because it's proven to work stable.
2. You can specify hosts file, which you want to use. In default configuration we use AdAway's hosts file, with more than 30 thousand of records, which results in extra ~2.5 MB memory usage. You have also an option to use MOAB (Mother Of Ad Blocking) hosts file, with more than 330 thousand of records, which will result in about ~30 MB memory usage. Eventually you can append your own rules or use non-standard hosts file, available in /system/archidroid/etc/hosts. Pro tip: You can point AdAway to use this hosts file (/system/archidroid/etc/hosts_adaway), which will result in automatic updates. /system/archidroid/etc/hosts is a symbolic link, either to hosts_away or hosts_moab, if you want to specify your own hosts, you can delete symbolic link and write your own rules.
3. Original /system/etc/hosts file has been locked from editing. This is to ensure that AdAway or other adblockers won't use obsolete and slow method of blocking ads through hosts. The whole point of implementing Adblock in ArchiDroid is to provide you with super-fast, flexible and effective way of blocking ads, also with getting rid of black/white ad screen. In 99% situations you don't want to touch ArchiDroid's default behaviour, as it blocks ads perfectly. Eventually, if you have a very good reason, you can unlock original hosts file through ArchiDroid's Backend Control and modify them, however keep in mind that every additional rule WILL slow down your network speed.
4. In default configuration local dns server uses two OpenDNS servers at port 5353, two Google DNS servers at port 53 and up to two local DNS servers provided by your Wi-Fi/3G connection, which overall gives a sum of 6 remote dns servers. In some rare scenarios (f.e. some wi-fi hotspots) you can notice that a moron, administrator of this wi-fi, blocked all dns queries and forces you to use his DNSes. This is BAD because of freedom and so on, but it's very common practice, that's why I turned on local DNSes as well. If you want to improve your privacy at least a bit, you can disable local DNS servers and then use only OpenDNS and Google DNS.
5. Above option initialy has been written to allow you one-time access to such non-trusty wi-fi's. But if you for any reason need automatic update of your local DNSes (3G and Wi-Fi's will use different local DNSes), you can also turn on Local DNSes Daemon, which will automatically query and update local DNSes if needed. This is also turned on in addition to local dnses above, of course in default preset.
ArchiDroid's Forced Update (RunOnce)
Forced update selected during mode selection in aroma tells RunOnce to work in "INSTALL" mode even on "UPDATE" mode, apart from that it works exactly the same as update mode, only RunOnce is affected.
