Thanks for the report. Is it possible that the mentioned class file is corrupt? Can you view it with javap:

javap -c -private -verbose -classpath PGInAppAAM/libs/BillingClient_v2.0.jar com.quixotic.aambilling.internal.Base64

If that works fine, is it possible to attach or mail me the class file com/quixotic/aambilling/internal/Base64.class or the entire jar?

[Muhammad Saqib]

jar is attached

[Muhammad Saqib]

thanks for your help. I think you are right. I am getting the following error with javap

java.io.EOFException

but it does decompile successfully with JD-GUI

The class file is corrupt; there's not much I can do about it. You should check with its creators if there is a correct version.
