@romanholidaypancakes I never could get it to work.

PS C:\Users\thher\pbtk> py .\gui.py
Traceback (most recent call last):

    for name, contents in self.extractor['func'](input_):

    with JarWrapper(path) as jar:
         ^^^^^^^^^^^^^^^^

Do you have an APK where you can get it to work ?
Ideally the Google Play Store APK :)

hi, I have never worked with GUI before, and I don't understand reverse engineering on APKs. I opted for the simplest approach, which successfully dumped the valid protobuf files. I'm executing the following command on Windows.

./extractors/from_binary.py my_private.exe ./out

[+] Wrote 70 .proto files to "out".

However, PBTK does not work in Protocol Buffers LITE_RUNTIME mode.
