I don't think a Test step is the right place for the second compilation.

wouldn't this be out-android/Debug/apks/Blimp.apk?

I'd like this to be a bit more general s.t. we can specify different things to
do between starting and stopping the engine. Not exactly sure how to do that,
though -- I'll think about it a bit and get back to you.
