Proguard exception while creating release android signed apk

Question

I am using Google API for Google authentication in our project, but while making a release signed APK, we are facing some warnings such that we are not able to generate the signed APK. Please point out where the actual problem is.

Try adding this to your proguard-project.txt file: -keep class * extends java.util.ListResourceBundle { protected Object[][] getContents(); } — IncrediApp, Jun 01 '13 at 06:23
make sure that before you relase your apk you must fully installed your app on device or emaulator. — Sharad Mhaske, Jun 01 '13 at 06:43
after complete installed then export signed Apk.check if its working. — Sharad Mhaske, Jun 01 '13 at 07:47
