By far my most common problem is the following crash:
signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
libCore.so (offset 0x1000)
I'm using AIR 22.214.171.1243. No idea what causes it, but my game is very large and complicated!
For some reason my Android console is not showing me a Crash or ANR rate - maybe because my app is still in testing and not fully published yet. I could try a newer version of AIR and see if that helps - I was already getting this crash before adding ANEs.
