So I published my android app, I proguarded it, applied LVL and even changed

  • 0

So I published my android app, I proguarded it, applied LVL and even changed some of the LVL code but offcourse, I found it cracked somewhere using a tool called Lucky Patcher. I am not going to ask how can I protect against 1 click tools like that, as I guess there is no single answer ( unless you have an idea and can point me toward).

I need to ask you to help figure out how my code was cracked. I understand that this tool takes APK file and removes licensing. Now given that, how can I take this APK file and reverse engineer it back to Java files to see how the tool cracked my code (so I fix it)

Please help me
Thanks

    After Proguard, there’s no way to decompile your code into humanly-readable Java.
    While it makes the reverse engineering process more difficult, it’s not impossible for a clever reverser to figure out the hidden algorithm.

    As for tools,
    Use android-apktool to decompile to smali and extract all the encoded xml resources.
    Use dex2jar to translate Dalvik into jar
    and finally jd-gui to see the resulting reversed java code
