问题
in android there is any possibility to getting source file from .apk file.
回答1:
It is possible. You need a decompiler for that. But be careful to consider the legal issues.
I use Dedexer or dex2jar. Most times there are good results, but sometimes it is not possible to decompile all sources.
回答2:
Well, normally you can't or shouldn't be able to, but you can try to 'reverse engineer' the apk (as its called) by using android-apktool:
