Bug? Compile Error: Packing Files. Error

I have uninstalled and installed Basic4Android and the AVD Manager 5 times, and the same error keeps going. When i Release or Debug a project, in the compile window, appears "Packing files. ERROR". I dont know how to repair it, i have tried a lot of stuff. Does anyone knows how to fix it?

AVD is not related. Make sure that the android.jar field under Tools - Configure Paths points to the file in the Android SDK. It will not work with android.jar from Android Studio.
