Describe the bug

Please add a clear description of what the bug is, and fill the list below.

  • CameraView version: 2.7.2
  • Camera engine used: camera2
  • Reproducible in official demo app: no
  • Device / Android version: Pie, API 25
  • I have read the FAQ page: yes

The scenario is like this. We had a timer set for taking pictures every 5 minutes. Occasionaly the app would get a SIGABRT to be killed when creating a new CameraView fragment for taking a new picture. After checking the logcat and stacktrace, we suspect that there might be something wrong with the states of CameraOrchestrator or WorkerHandler. So we passed true to recreateHandler in the CameraEngine constructor and never got crashed again. p.s. After 2 more days' of pressure tests, it crashed again.

CameraView/cameraview/src/main/java/com/otaliastudios/cameraview/engine/CameraEngine.java

Line 158 in 0057981

recreateHandler(false);

My question is, is it possible that WorkerHandler used an old thread while its Looper had quit?

Expected behavior

A clear and concise description of what you expected to happen.

This seems to be a system level bug in Looper. This crash happened when a WorkerHandler thread was created and cached and a new CameraView instance was created and it was awaken up by an alarm.
I finally changed how CameraEngine use the WorkerHandler to do a workaround. Whenever recreateHandler() is called, a new key is used to create a new WorkerHandler; when CameraEngine quits, the WorkerHandler quits then.

Thanks for the information. I don't fully understand what's going on though. Is there something the library could do, other than creating a new handler each time?

I strongly suspect there's something wrong with my version of Android Looper at the very core. https://android.googlesource.com/platform/system/core/+log/master/libutils/Looper.cpp

More information, the device we're using is for surveillance purpose on power towers. There's no user interaction. So we only set up alarms to do picture shots repeatedly, say, every 30 minutes. After each picture taken, the device would go into sleep mode to save battery as soon as possible. A crash may occur on each second wakeup to do a picture taking. If we delay some time, say, 100ms or more, to do the instantiation of CameraView, it seems the crash case would not be touched. Weird? Since this is probably a bug of the underlying Android system, as we can see from stacktraces of each crash, I don't think there is a need to do modifications to the CameraView. It is a great library. Thanks! Moreover, this crash case only occurred to an Android 9 device, not on other kinds.
