Hey, my project is a bit special because I would like you to datamine the music of the mobile game "Pokémon Masters EX" the game is coded in Java and nobody could extract them because the encryption of the game is different from that of the musics (we can extract everything with a tool except the musics) Also with reverse-engineering you can extract all sound file and create an extract program (in c or java or other) for decrypt all music in future update of game (if encryption not change of course)
Precision : it's not the apk data, it's the Obb-file data (download in app) and after we decrypt the all file (a Guy have create a "project extract" but he software extract all file except sound file because he use different encryptment) If you want i send you file + "beta-tool" from the guy
