How to prevent My apk from decompiling
as you probably know - decompiling APK file is too easy:
extract the apk as zip - reviles compliltly the manifest and all resources.
using simple decompiling software - reviles all the source code (only with not the original variables names..)
I would like to know if there is a way to secure somehow APK file from been decompile.
I assume that reason I need this is obvious to all of you - I don't want people to read the source code or any part of it, from security reasons...
thanks in advance
Use proguard. It shrinks, optimizes, and obfuscates your code by removing unused code and renaming classes, fields, and methods with semantically obscure names. The result is a smaller sized .apk file that is more difficult to reverse engineer.
