Android Proguard error with Google Drive API

Question

I stated using Google Drive API in my project.. Every thing works fine if i run the project on phone using the debug keystore.

when i try to create a signed APK, proguard throws me the following error

I also tried adding the following into proguard-project.txt

-dontwarn org.apache.harmony.**
-dontwarn javax.activation.**

If I add the above, APK is created, but the APP crashes on launch

can anyone please help me!

You're referencing classes that aren't part of the Android runtime. Either remove the classes referencing them, or if you just want to suppress the warnings, try adding

-dontwarn java.awt.**,java.beans.** to your proguard config.

Additional info in the ProGuard Troubleshooting Guide.
