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.
Hi Forum Members,
I am trying to access the clock application that comes on the Samsung captivate. I noticed that its different than the stock clock application in the Android 2.1 source. The widget used to to type in numbers looks like its custom and not the phone widget used in the stock application. I downloaded and extracted the source but I don't see any of the custom samsung app implementations?? I also tried opening the captivate source using eclipse but there is no project file. Could someone point me in the right direction in getting a project created in eclipse using samsung source and accessing the samsung application. I am new to development on the captivate. Thanks.
The Samsung apps have not been open sourced. The things they've made open are the kernel (only the parts they had to, so even some custom stuff is not present) and the mods to the stock eclair tree that are required to build stock eclair. Look at the readme files for instructions on how to build that - there is no Eclipse project because there are no apps in the source and the method for building the kernel and stock eclair is all command line make based.
If you want to build a clock app, this isn't the level you should be working at. If you want to modify the Samsung clock itself, then you're out of luck because that is not open-sourced.
Thanks for the reply - you're right after doing some digging (and finding the README.txt) I realized that I wasn't going to find what I was looking for. Now I am currently building a stock samsung eclair build....
thanks again.

Kernel Development
This is a general guide for building kernels and modifying them. Device-specific articles for getting the kernel source and setting up the build environment are provided in their respective sections.
Getting the kernel source
The source for your kernel must be made available by your device's manufacturer in order to comply with the GPL.
I dont know where to get it
Setting up the environment
Instructions for setting up the development environment should be included in your source code package. This should tell you the parts of the Android Open Source Project that must be in your working directory in order to allow the kernel to build. It will tell you what version as well. All of the Android Operating System source code is available at [android.git.kernel.org] and most projects are mirrored at [github.com/android]. Both are accessible via your internet browser as well as git.
Modifying the kernel
After the kernel source has been downloaded and your environment is set up, you can begin modifying the kernel. It is recommended (in most cases mandatory) that you run the standard "make xxx_defconfig" for your device before modifying the configuration.
Running
make
or
make -jX [where X is the number of operations to perform at a time]
at this point will make the stock kernel that your phone's official system has. To modify it, we can go two ways: 1) modify the file '.config' in a text editor, or 2) run
make menuconfig
for a graphical interface.
Modifying '.config' with menuconfigEdit
Typing
make menuconfig
will bring up the aforementioned graphical interface for modifying your kernel. Striking the "y" key when an option is selected (with "< >" or "[ ]" before it) will include it in the kernel. Striking the "m" key will add those options with a "< >" as a Linux kernel module (*.ko).
Adding tethering support (netfilter/iptables)Edit
Adding VPN support (TUN)
Adding Linux swap support
Adding ext3/ext4 support
Mofifying '.config' manually
The alternative to using menuconfig is editing '.config' in your preferred text editor. Options that are not to be included in the build are commented out with a "#". Options that are to be included inside the kernel image are uncommented and have the value of "y". Options with the value "m" are to be built into loadable kernel modules.
Adding tethering support (netfilter/iptables)Edit
Adding VPN support (TUN)Edit
Adding Linux swap supportEdit
Adding ext3/ext4 supportEdit
Packaging and flashing your kernelEdit
Additional stepsEdit
You may find that you want to play around with '.config', but don't want to lose your configuration. You can rename your '.config' to whatever you want and give it the suffix "_defconfig" and put it in "arch/arm/configs/" for the next time you wish to use it.
For example: if you had a kernel that had tethering and ReiserFS support, and you wanted to try enabling VPN without breaking your current setup, you could rename your '.config' to 'my_rfs_tethering_defconfig' and move it to "arch/arm/configs/". The next time you wanted to make this kernel you could run
make my_rfs_tethering_defconfig
and have your kernel configuration just as you left it.
Note that this would overwrite your kernel configuration stored in '.config'

There is also a book named "Learning Android" written by the same person who uploaded the videos above. I am new to android development and new to Java even,and I found these tutorials very useful ..... I am posting this because this may help someone
I sure does Help! Thank you for your contribution

Is Android based on Linux?
Hello everyone,
After developing some applications for Android I decided to get the source code for Android 4. I want to change my "Home" application. Actually I don't want to change it at all, but change it a little. I download the source code using repo from the branch Android4.0.3_r1 (I don't remember exactly). Under the folder "/packages/apps/" I get the "Launcher2" folder and import it at the Eclipse. Then a miracle confused happened! There are undeclared variables, undefined methods, etc! I cannot understand a thing!
I want a little help for:
- Making this source code run
OR
- Downloading the right source code.
Could you help me how to find and run the original source from Google?
no one has had (as far as i know) any success porting the ICS launcher to 2.X
you may want to look into a custom ROM, or a themed launcher.

Hi again,
Actually I am not trying to port an ICS application to Android 2. Launcher2 is the name of the application for Android 4. Launcher2 works as "Home" application, as I understand.
The problem is that from the source code provided by Google there are errors. Undefined methods, etc. Is there any way to compile and build the Launcher2 application and disappear these errors? And, if there is no way to do it do you know any similar open-source application?
Hello everyone,
First of all I want to thanks community and congratulations for all this great information.
I'm working in my final career project, and I want to present a tool for helping in static and dynamic analysis of APKs ( if somebody want to take a look it is AndroidSwissKnife in github) .
The dynamic analysis I took the code from the project DroidBox (mentioned in my code), I updated it to Python 3 (fixing some problems). But now I have a problem, the system image that comes with DroidBox is an android 4.1.
As part of my project I want to update my tool to support Android 5.1, or even Android 6 and I need to modificate in any way the android image to hook some method calls, and I thought in Xposed framework.
I would like if anyone can give me information to start learning in the android's security world, custom ROMs and Xposed framework.
Thanks to every one. Kind regards.
