ANR occurs after calling #queryMapForFeatures #2669
Description
Environment
- Android OS version: 5.1.1
- Devices affected: Rockchip RK3288 Develop Board.
- Maps SDK Version: 10.7.0
Observed behavior and steps to reproduce
We try a lot times to replay the situation. But no error shows agains.
After tracing , we found a LOCK. After calling queryMapForFeatures then acquire this lock causing the whole system thread blocking. So i believe that would be the key point.
Here comes the ANR log which is indicated the API queryMapForFeatures.
