Alpaka

Alpaka is a tool for mapping classes between different versions of the same APK.

Usage

Output a JSON mapping from A.apk to B.apk:

> alpaka map A.apk B.apk1
{
    "LX/003;": "LX/003;",
    "LX/004;": "LX/004;",
    "LX/005;": "LX/005;",
    "LX/006;": "LX/006;",
...

You can also --deobfuscation to supply an enigma mapping file, and it will be mapped to the new version:

> alpaka map --deobfuscation A.mapping --only-obfuscated A.apk B.apk1 > B.mapping

These enigma mapping file can then be imported into Jadx, in order to keep manual renamings from previous versions!
