Afaik you need a .NET environment to run C#. I'm not a Linux expert, so maybe my statement isn't correct: I know that Linux's mono framework also supports C# code, bu tI can't say whethere there's such a framework for Android. Neither do I know whether such a framework wouldn't slow down everything just by itself.
It would be
As it turns out, the guys of Xamarin created an C# ported clone called "XobotOS".
I played a lot with the thought of compiling/patching it (it has been based on Android 2.3), but the definite downside would be, that no Apps whatsoever could be installed if not compiled.
As long as I do not have the time to investigate, whether it is possible to decompile apks and rearrange them with .NET IL code, this is no option for me.
Why would it be faster? Obviously the VM is a lot more mature than the Dalvik VM.
Google confirms that.

Hello!
I want to start developing apps for WM, but im stuck with a question in my mind.
My first app i did it in VS 2005 and now im trying VS 2008. Also i have some HTML skills and I want to know what other software is used to create WM apps, other then VB & VS.
I would like to know a few(free if possible ).
Thanx!

If you want to make some games, game editor is excellent for that. Iam making a cut the rope for windows mobile with it , I will let you know when its released. There are some limitations , but its free to use and simple to learn. The games in the website in my signature where made with game editor , go check them out.
You may struggle a bit here. All versions of Windows Mobile are running a version of Windows CE .NET, the vast majority of them on an ARM powered device.
Most of the operating system will have been written in Win32 C/C++ with a few touches of ARM assembly thrown in for device drivers, CE components etc.
ATL and MFC are both C++ class wrappers for the underlying Win32 stuff.
The .NET CF is the Mobile Version of the .NET Framework and again is a wholly Microsoft set up. (VS 2003 onwards)
Mono is a GNU linux .NET alike product and can be used to create CF exectables. It's free, but there are a few caveats. The first one being the fact that WinMo will refuse to run exe files created by Mono until you patch its compiled key. There is no real test or debug environment. It will be code, compile, patch, copy, run and crash ad nauseum, until it works! Also the QTK graphics objects, have not been ported over to WinMo.
The only 'free' MS offering is Embedded C++ 4.0, but it is C++ Win32/MFC/ATL only and takes a lot of hard work to master, and it was only really meant for development for WinMo 2003, although correct design of an application will allow it to run on later versions and appear like a MinMo 5/6 program.
Use of GPS may scupper your efforts, you will need VS 2005 or later.
To sum up, it's a minefield.
So if this is a stupid question - please be kind.
It seems the Prime has the power to run the full Java instead of the phone based version.
I noticed this the other day when I was trying to run a java video app from within BlackBoard for one of my assignments. I just get a bunch of symbols at the top of the frame and it extends the screen endlessly to the right.
So is adding the full java something that can be done in a new firmware update or be a part of a rooting package of the future? It sure would be nice to take advantage of the power of this tablet by adding the upgraded java.
Thoughts? Suggestions? Am I crazy?
Dalvik is a full JVM, it's just that Android doesn't implement a lot of the Java libraries dedicated to writing desktop apps. It might not be too much work to get, e.g., hidden Java applets running. It would be a lot of work to get Java applications with graphical interfaces working.
I think it'd be cool to run a Minecraft server off my tablet... but that's just me.

But this tablet has the horsepower to run it if it were done, correct? I'm just thinking quad core tablet- a GB of ram. Seems like a ripe apple for the developers to add something a little more tricked out in the software now that there is hardware that would support it.
Of course I am not a developer, but my understanding is java is scaled back due to hardware limitations. The Prime is a beast of a tablet. What would it take for this to happen?

A lot of time and money? Months of work at an absolute minimum. I don't know all the missing APIs, but at least pretty much all the graphics stuff from desktop Java is missing on Android.

Oh crap. Well..... I suppose that hope just went out the window.
I am happy with the Prime as it is. I was just curious about the possibilities of taking it to the next level java wise now that there are devices capable of running it.
I see you are in SA, Noxious. I'm just up the road in Austin. Have to come down there every other month or so to Methodist Transplant hospital. Had a liver transplant almost 5 years ago now. Graduated from Judson.
Thanks for your replies.

You can run Java SE and even a JDK but you lose Android integration. Example: I have JRE/JDK and most of the Android SDK running on mine, in a Debian chroot. All I am missing seems to be a couple x86 C/C++ programs that I don't know where to find the source for, otherwise I could get them ported to ARM and do Android development on my tablet with the usual build system (not what terminal ide does).
But note that if you want to do GUI crap in Java, like AWT/Swing/JWT, then you need the x11/vnc stuff or to push the built code to another machine you can remote into. Running headless Java code is also possible via dalvik (just like the Android SDK does for what goes into .apk files) in some cases but I would not want to test complicated parts of core libs and classpath dancing.

Run Linux (ARMel or ARMhf) OS ontop of Android and run "ARM_Linux_Moder" from the following link after cloning it to the Linux file system
https://github.com/S0AndS0/Debian-Kit-Mods
Full directions are in readme file and I've a guide on xda and google docs to set up Linux on Android using Debian Kit.
Currently you can run JDK hard or soft float on Android and run almost any .jar file or java program that runs on PC Linux OS's using the scripts provided and install Java dependent software I've tested and scripted installers for.
I'll be working on Android SDK and NDK soon.

Hello All,
My question is whether the reverse-engineering of iOS's API is being looked at as an option any time soon. I would be interested in something similar to Wine (Wine Is Not an Emulator), which is a reverse engineering of the Win32API and allows you to run Windows .exe files natively in Linux or Mac OS. I am aware of iEmu (and it's unfortunate suspension).
However, my interest is not in getting iOS itself running on my phone, but instead I would like to run the apps themselves. I'm pretty sure there isn't currently a project on this. If there is, can you inform me of it?
If there is not, I would like to discuss the difficulty of implementing this. I could definitely be an aid in starting a project of ths nature.
Here are some things about iOS's apps I am unfamiliar with (I am aware that this specific section of the post may be more fit for the iOS forum):
Does the Obj-C code compiled for iOS resemble native ARM code (the iPhone chips are ARM to the best of my knowledge), like how C++ would be compiled, or does it resemble something more like C# or Java, compiled into bytecode that is executed by a library?
Compared to the size of the .NET framework or Win32API, how big is the iOS library?
Has a successful program been created that can run Obj-C code?
Would this have to be worked from the ground up (figuring out how Obj-C compiles in the first place), or has there been some effort already mounted similar to this?
I am aware of the extreme difficulty in implementing this. However, I'm sure this was thought while planning Wine or Mono. I'm not even suggesting this be made, but I'm simply asking on your opinion on the general difficulty (can it be done).
Thank you,

Hey and welcome to the forum's I would like to know this as well but I do not know any project and any that gets started and gains popularity gets chased down by Apple's legal team quite quickly. I have my doubts that this could happen (I would be glad if someone could prove me wrong) because iOS and its apps work on 12 devices and Android has hundreds of devices, most with different hardware. Windows apps are built for variable hardware, likewise with Linux and now Mac OS X. Sorry but as much of a pessimist as I seem I do not think it's possible but I'd love to be proven wrong. (Can someone at least make a frigging Windows Mobile runtime)
Has anyone seen this?

This could be the bomb... coding in C# for Android natively!! Even maybe some of the good developers here at XDA could make a C# native Android ROM with a Dalvik machine for compatibility with non-C# market apps??
They have made tests and it seems that C# ROMs run like 5-8 times faster and leech much less power ...
Cheers!!!
Java and C# is brother actually. Both have virtual machines, both came from C++. But creating a new variation of one of these is so unreliable. Dalvik is Basically Java's clone but not very succesful clone. Mono is C#'s VM's clone and very reliable. Linux, Mac and Windows has Mono Ports (actually windows has .net framework) Mono is great but you know microsoft doesn't like UNIX like systems especially linux based ones. Thus C# programming could be harder for people. Also C# for phones could be awesome. Since 2000's We already have javaVMs on phones. Why Not C#. (python is good too but google wants a new language called GO)

I think the problem is much greater with Google since they won't want a M$ programming language in their OS ... and that's a reason for which I'm sure they won't never support C# Android, but another thing are community ROMs.
Let time judge it.. but I think its good stuff...
Not only they do not 'want', they probably are not allowed as c# has patents. Look what is happening to google with java now owned by oracle..
Hello , i have an IT project lined up regarding the programming of an android app (a high level)
i would like to know that which is the best free book/pdf document is available online for learning android programming.
i have started learning python, i just wanted to know whether it can help me in any way?
Emmm....I think python won't help. By the way what languages do you know? If you like you can continue your project with Mono Android. Which is compatible with Microsoft Visual Studio and you can do many things easier with it. In that case you have to know C#. Here's the thread with many links. http://forum.xda-developers.com/showthread.php?t=2223114

Do yourself a favor and simply use Java if possible. That is how they intended to develop on Android. In my experience anything else is good only if specifically needed.
JAVA is the most used language to make apps for Android but there are alternatives and the biggest I see is Mono fro Android which uses C# as a programming language

I second that. Android is mostly designed around C and Java. Even if you code C/C++, you sometimes have to use JNI to call back into Java, because some functionality is only exposed in a Java package, not in native code.
So Java is the best way to make full use of the Android platform, and gives you the best compatibility. Most tools, documentation and other resources are also aimed at Java development.
Java is default android development language

you can develop android app with python but maybe your released app size is so big
because your app must statically have python interpreter.
it is not easy stuff, if you have not many experience of android development.
python is not too far from java or c/c++ so it may help anyway, but now you should go to java ...
but the most important is now to know how to use the Android framework
Nowadays, Java is the most useful language to create application for android, but I will prefer mono for C# as a programming language.
yeah...man u should use java it would really help u.....i m 14 i too wanna develop apps...so i learn JAVA it's the best ....
By the way gud luck with ur project
