How to use proguardgui to obfuscate an apk

i need to obfuscate an apk and aab with ProGuardGui (due to the project can not be obfuscate by gradle run in androidstudio , ok it’s another Question), but it doesn’t work and show me a dialog “The input doesn’t contain any classes. Did you specify the proper’-injars’options?”

i have no idea , thx for replying

Dear @ganguanglong,

Welcome to the PG Community!

ProGuard doesn’t support APK and AAB processing via the ProGuardGUI. As a result this will not be possible. You will need to integrate through one of the other means.
Please let me know if anything is not clear.
Best regards,
