My initial guess is that this is just an invalid dex file. Can you confirm 
whether this dex file actually works on an android device? My suspicion is that 
the dalvik verifier should reject it.

If it does actually work on device, can you share the apk? I'll need to take a 
deeper look at it to figure out why it isn't working.
