Well, I donβt know the answer, but I can provide you with a cheat code for this.
Download the app app app app Facebook and then decompile it
Change the facebookapp.apk extension to facebookapp.zip, click "Yes" to display a dialog box. Thanks to this, you can view the manifest and xml layout files, but the code is still not available.
Than you found them the classes.dex file, which uses dex2jar to convert classes.dex files to classes.jar.
Use the Java Decompiler (jd-gui) or eclipse to view these class files.
You can do this in any application, this way you may not get the exact code, but get the basic idea of ββhow the application works.
For any problem, google also for the tools you need that you can easily find on Google.
