Hi, I have the same problem. Mobile temple, Tappy Chicken and Swing Ninja builds without a problem. I’m also looking for an answer.
For me, I get an error (sorry, didn’t save the log) about the apk not existing.
I suspect that there was some other error in an earlier step that lead to the apk not being built, but I don’t have any more info right now.
I also tried using different texture compressions (etc1, atc, all combined) with no success.
