Familiarity with ANR in sharedPreferences, I don’t know how to find the problem.
Here are the three parts of the trace, most of the other threads are WAIT or TIMED_WAIT. "main" thread is blocked due to countdownlatch.await (). 2nd thread "pool-1-thread-1" waiting for fsync. The latter is trying to read something.
I think the 2nd thread blocked the main thread, because if this one cannot finish, it will not call countdownlatch.countdown (), so the main thread should wait.
But I can not understand why it stops at fsync. Is this third thread related to this?
