Hi All,
I'm a noob ROM developer and I want to create a new Rom based on
one of the great Roms here on this forum and add it support for RTL languages so it can support correct display of numbers when displaying an RTL lang.
As I understand I need to somehow decompile the "classes.dex" so I can edit the code in it and compile it again.
How can I achieve this? Maybe I can the original source code of it so I don't need to decompile?
I'm experienced with c++ and Java Android apps development but don't have a clue from where to start roms development.
Appreciated your help,
Thanks,
Oren
Hello! I'm not sure am I allowed to post this kind of question in this forum, but I couldn't find any better place.
I would like to modify (edit) my SGS II's ROM/kernel. I've already downloaded source from opensource.samsung.com (GT-I9100_OpenSource_Update2, 2.3.5).
I'm not new to programming but I just don't know how to "edit" that ROM/kernel. I have Visual Studio (I know the basics of C/C++, and I'm good at C#). Kernel is the lowest-level "program" so I guess it's written either in C or C++.
So what I'm wondering is how do I open the kernel or ROM in Visual Studio and am I able to compile it later with VS? (I just saw compiling tutorials and everyone is compiling on Linux (I'll install it if necessary)).
You don't have to write me step-by-step guide, but just help me a bit.
Sorry for my bad English by the way.
Link to download GT-I9100_OpenSource_Update2 from linux shell
If anyone is trying to download the files from linux shell, you need to find the file's "attach_id" which you put in the cmdline below to download what you need.
In this case (attach_id=1584) it's GT-I9100_OpenSource_Update2.zip
Code:
wget --post-data="method=downLoad&attach_id=1584&down_purpose=EETC" https://opensource.samsung.com/reception/reception_main.do?method=downLoad
Hello everyone
I have a question, first look at what I did.
I want to edit code of apk.
First, I use dex2jar. I can convert from APK to JAR file.
Second, I use JD. I can convert from JAR to Java source code.
Then I am trying to import these code into eclipse (or other editors) but it is not working.
Is there any possible way to edit the code?
I know we can edit smali but I think it is so much difficult.
I would be easier if I can edit in java source code and compile again to APK.
Thanks
Please use the Q&A Forum for questions Thanks
Moving to Q&A
It's not that easy. You can decompile (dex2jar & jd) the code to read it, do some research, etc. but this is a one way trip. If you want to modify something you will have to learn smali.
so, you mean the only way to modify code is smali?
Hi,
I'm currently woring on creating a complete VM and a document with instraction of getting from compile to flahsing from begining.
The complete enviroment will be set and ready with the Stock ROM (currently targeting 4.0.2.A.0.58) and the Android OS.
This will allow users to be able to take this VM and start right a away to change the Stock ROM and integrate changes for that from other modes.
will update this thread when it's done. and links for download (unless someone will be faster the me )
18/12 Update:
Just now finish creating an working and compiling enviroment with 2.3.4_r1 of Android
now working on making it to work with the Sony Ericson source code...

Hi,
I need a little help here... i have followed the steps in Google:
http://source.android.com/source/initializing.html
and also the Journal:
http://journal.tianhao.info/2010/12/compile-android-gingerbread-on-ubuntu-10-10/
i have compiled the code and got it up and running and also in emulator with the command line that was written in the Journal and the Android is working..
now i try to understand the Sony Ericson guide:
http://developer.sonyericsson.com/wp/2011/05/06/how-to-build-a-linux-kernel/
I have downloaded the ARM cross-compiler and installed it, was really bad instructions on how to install it. but just need to run: sh ./the_downloaded.bin
and installed it correctly
after installing the ARM cross-compiler successfully done a make to the kernel but only after fixing the symbolic link that from some reason was attach to 0x86 arch and not arm.
the paths where different since i used the default installer path and match the same version that they used: 2010q1
so first done this for the .config :
ARCH=arm CROSS_COMPILE=~/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi- make semc_zeus_defconfig
Click to expand...
Click to collapse
then run the make:
ARCH=arm CROSS_COMPILE=~/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi- make
Click to expand...
Click to collapse
now i got kernel compiled!
the question is:
i know that with the Android compiling i got 3 files in the /source_android/out/target/product/generic:
1. ramdisk.img
2. system.img
3. userdata.img
do i need to use the ramdisk from the Android for the next steps of SE guide ?
1. Getting a RAM disk and extract it
2. Re-package it with all of the kernel of SE that we just compiled
3. Assembling the boot.img using the mkbootimg
moreover, after i assemble the files i want to make a really clean installation and cleaning all the flash and installing all in a vanilla mod.
what should be the next steps ?
Regards,
LaBBa.
I thought that the community here will help in this small matter so we will have more pepole that could join the efforts of making brtter and cooller roms... I guess I was wrong. All I wanted to do is help the dev community and create the full step by step guide to starting developers in the android world....
Sadly I'm forced to end this thread due to lake of knowledge...

im sorry i would help but i dont know much lol srry no one that knew could or would help
hi,
I hope that you are able to get this working.
i will use it when it is finished
Edit: what have you exactly done?
Maybe i can help
all i wanted to do is to download all the source codes and compile it and then creat the same version (for this case the .58) manually and get to the same images that need to be flahed.
i wanted to create from this a complete tut that others that have allot of knowladge in development could start working without the stragling of setting up an eviroment or all the issues about how to get from compiling to acctuall creating an .img to flash it on your device.
just a simple "out of the box" solution so pepole could get and work right a way without wasting time in assembling the source codes and setting then env.
ok, and where are you?
I mean what have you done for now??
please see the second post.. it's all there..
yes you need that ramdisk for the kernel.
but you need to edit the ramdisk to work with the xperia play.
i can do that, can you upload it??
what i'm going to do now is, i'm going to upload all the VM to the web and write the complete tutrial for all the steps i have done so far and then we could continue. thank you for trying to help!
ok,
if you need some help PM me!
i know that lib.so is an elf file, and all i can open it is via ida pro. so here is my doubt, how it is build, and how can i get its source code? i like to modify some lib.so, and is little bit used with elfs( used them to do things with old sony ericsson java phones). some dev pls help me.
