ANR caused by classic deadlock

[matt-msi]

This was previously reported on #140 but might have gotten lost in the shuffle. Our test team has now reported seeing ATAK crash with this same ANR backtrace half a dozen times. Is there any chance to investigate why the two threads are deadlocked on each other, or has this already been addressed in a newer release than 4.5.1.13? Would you recommend updating to the latest open release (4.6) assuming it has any goodies in the bugfixes?

Are you still seeing this deadlock in the latest playstore release?

I don't think we have ever seen this one on a playstore build. It crops up from time to time when we get an ANR reported and in the backtraces we see the two threads are stuck waiting on each other. If there hasn't been specific work around the graphics threading model then I would expect this issue is still there.
