I am getting an instance of a telephonymanager (single or multisim devices) and got several ANRs. I have managed to work through most of them but this one persists:
*Broadcast of Intent { act=android.intent.action.SCREEN_OFF flg=0x50000010 (has extras)
What's the best way to deal with this? Some of these were only reproducible when leaving the app open and the device's screen on for several hours. This makes it difficult to debug ANRs such as these.
There is a part in the report that says that the running is "locked". How do I distinguish if this is a deadlock or when the thread is waiting for the current operation to complete? The callbackDataConnectionStateChanged(), refreshTelephonyState() methods are synchronized
