Improve android ANR detection #2446
Description
What problem could Sentry solve that it doesn't?
Recently we face problems with ANRs increase rate on android platform.
During the investigation we enabled ANR detect mechanism in sentry unity SDK and saw that we don't have any stack trace with information regarding ANR.
As we saw in documentation this behavior is expected since we get the stack trace from background thread. Instead, we would request to do mechanism that will work from native part of the sentry and make stack trace dump from all threads including the game thread.
As result we would see ANRs on android same way as we see iOS App Hang events
