Which steps are missing/not clear in the readme of the project? Docker instructions are the same for each os, just install docker by using the official guide, pull or build locally the docker image and then follow the readme to view a description of the available parameters.

When I run above command, it gives me below error.

Please see https://github.com/ClaudiuGeorgiu/Obfuscapk/issues/127#issuecomment-1027705016. Also, I suggest starting only with -o Rebuild -o NewAlignment -o NewSignature obfuscators and without specifying the keystore, just to check that basic commands work (if that works, then you can add all the other parameters, this way it will be easier to debug in case of errors).

I suggest starting only with -o Rebuild -o NewAlignment -o NewSignature obfuscators and without specifying the keystore, just to check that basic commands work.

If this works, the issue is with one of the obfuscators, otherwise it's an Apktool issue (or the app is using some anti-repackaging technique).

@ClaudiuGeorgiu I want to tell more thing, I developed application on Flutter Framework. It's alreay obfuscated many code, but it didn't obfuscate the com folder.

ClaudiuGeorgiu commented 1 year ago

This seems to be an Apktool issue, since it's not able to rebuild the application even when no obfuscator is used. You could try using the latest version of Apktool (v2.6.1). However, Obfuscapk was not tested with Flutter applications, so I'm not sure that it will work (even if Apktool was able to rebuild the app).
