Android Dex: UNEXPECTED TOP-LEVEL EXCEPTION: Already added

Question

My app depends on a library project. This library project depends on the Android Compatibility Package V4. I have NOT exported the library project\'s depend

Answer 1

In my case, I had just updated one of the JARs in the libs/ folder to a new version.

All it took to fix it was to run Build -> Rebuild Project, i.e. issue a 'clean' task before the 'assembleDebug' etc.
