When I upgraded my Android app to depend on build tools 22.0.1 I got this exception (see below) on my device.

I believe it is the same problem described in the response here: http://stackoverflow.com/questions/26685636/what-causes-the-android-dalvik-java-lang-verifyerror-invalid-reg-type-for-array

My workaround was to remove some local variables by referring to the original array indexes.
