I'm trying to learn how to modify certain android components but I'm having trouble compiling from source.
I downloaded Launcher2 from cyanogen git://github.com/cyanogen/android_frameworks_base.git but Eclipse says it can't resolved some classes.
Some of these classes belong to other repositories like android_framework_base core and graphics. Do I need to bring the sources for these too? will these get compiled into -the Launcher making it huge? What is the correct configuration for eclipse to compile individual apps?
Thank you in advance.
i have the same problems with u~
yes, you need the whole android tree.
then do:
make Launcher2
hope that helps.
Hello all,
I am quite new so please pardon my ignorance.
I am new to Android and trying to develop some applications with some success.
What I want to know is, if I want to extend/change a system application, for example, Phone.apk file) how can I do so without downloading the whole ROM source from GIT repositories. Also I will like to know is there a way to debug the same without building the whole source every time?
All the questions I searched were related to Java or general Android application development. I could not find anything related to extending/changing system applications. Maybe I didn't searched well enough. If yes, please point me to the right thread.
Any help will be hugely appreciated.
Regards,
Yogesh.
Hi there,
Now, I understand that there's a thread or two and a few web pages directed at compiling Android and its kernel from source.
However, the thread in question is months old, and didn't fully explain the process.
As for the web pages, they are mostly outdated and don't include enough information, not to mention desire specific instructions.
I think that, properly explained, building Android shouldn't be daunting, and everyone should be able to attempt it, if they wanted to.
So, I hope to compose a comprehensive guide on how to do just that.
The problem is that I myself have not been able to put enough instructions together to be able to complete a build. And there is no point digging up old threads.
So, If anyone who knows the ropes (that is, compiling android and a kernel from source) would be willing to lead the way, I'd happily turn it into an easy to understand guide.

I followed this guide here and successfully compiled a modified HTC Kernel and I had very little Linux and Android experience.
Obviously instead of cloning the Cyanogen git, you just use the gits you wish to compile

Thanks for the link
Though i don't fully understand the whole 'git' thing. Where do i find them? And how to i know which ones are the ones i want to use?
Josh
EDIT: Also, how do you 'edit' the kernel (i imagine it is somewhat like make menuconfig?). Also:
- Are these sense kernels?
- How do you add modules like OC and UV?

A git is a repository for source code, developers upload their source code there and can commit changes. The commit can allow descriptions of what was changed and also details the files changed.
The git system allows other people to add to the source if they have permission, or allows others to read the changes and download the source code.
Git links are usually posted by people who release software, as Android is GPL licensed so people have to release their source code if they're distributing their work.
Editing the kernel, take a look into the git and the commits and it will show you which files were changed and how exactly they were changed. That will give you the best understanding.
UV/OC is done by changing the acpu table in the architectures files and changing the minimum/maximum voltage figures in the board_bravo.c file.
The Cyanogen kernels are not Sense kernels no, it's a modified Google Kernel.
Thanks for the explanation. I followed the guide and built the rom, and it works (always a plus )
Now, the next thing is the kernel. How do I build a kernel with the CM tweaks integrated? I understand that all i would be doing is rebuilding the same one that is already installed, but im doing it to learn.
So, if i synced the GIT, does that include the CyanogenMOD kernel source? If it does, where is it and how do i rebuild it. If not, where do i find it?
Thanks,
Josh.
I have downloaded a stock rom to play with and figure out. I checked it out in a kitchen and was looking over the file layout (2.67.651.4). I also download a kernel source from HTC DEV (2.6.32) to have a look at.
I would like to have a look at how the side volume buttons function. Does this need to be at the kernel source level or can that be seen in a ROM?
If someone could point me where to start looking I would greatly appreciate.
Hello there!
Today I'm asking this question because I didn't found a question like this on XDA, and I was wondering why.
However, this is not so obvious in my opinion!
I know that you can find the Java code (in some sort) in the apk file.
But I checked some system apps (i.e. TouchWiz Mass Launcher, SystemUI) and I didn't find any code into these apk, only XML, resources, drawables and stuff.
So where can I find it? I'd like to modify system apps to add new features, not only for theming
Thank you in advance.
(P.s: Please avoid "U should install xposed its mor easy" thing because I do know that and I got it already. Just answer - or don't-, thanks)
