Here are numerous discussions of AAPT issues  https://groups.google.com/forum/#!searchin/mitappinventortest/aapt%7Csort:date   .  Some of these developers resolved their problems using the Forum provided suggestions.   Perhaps you will find a solution too?

Check for 'loose' blocks, block warnings etc. and clear them up. Did you previously build your app with a different compiler and are now trying to run the aia using App Inventor?

  Failing a solution after checking for 'obvious' coding errors, consider posting an image of your blocks here in the Forum; otherwise all anyone can do is guess.  You might review the stuff here too   monster list of tips and tricks       for a possible solution.
