Steps to Reproduce

I have no way to reproduce this issue i am sorry, but sometimes (4 times so far) i have the following error using the camera: ^0.9.4+5 package on my Android devices :

W/MessageQueue( 9684): Handler (android.os.Handler) {b3d2c3c} sending message to a Handler on a dead thread

Here is a bit of the code that handle the lifecycle :

@override
  void dispose() {
    // Dispose the controller when the widget is disposed.
    cameraController.dispose();
    WidgetsBinding.instance!.removeObserver(this);
    super.dispose();
  }

  @override
  void didChangeAppLifecycleState(AppLifecycleState state) {
    if (state == AppLifecycleState.resumed) {
      cameraController.resumePreview();
    }
    if (state == AppLifecycleState.inactive) {
      cameraController.pausePreview();
    }
    super.didChangeAppLifecycleState(state);
  }

I provide a bit more logs below that show maybe better the context (camera related) of what's happening at this moment.

Note : this is not crashing the application.

Do you have any ideas about what might cause this ?

Expected results:

The logs should not show an error IllegalStateException from Java code.

Actual results:

The logs are showing a thrown IllegalStateException.

The error log looks similar to this. Can you try the replication mentioned in it and see if you still get same error as above ?

Yes sure i have tried the replication but it seems fixed by the PR in his case.

However, the use case is almost like mine meaning when switching "pages".
I say this because before it seems the issue was related to the Activity switch in Android and I have a Navigator.pushAndRemoveUntil() called when this occurs.

Unfortunately, even by changing a bit the sample code provided (instead of the ImagePicker i use the Navigator.pushAndRemoveUntil()) i could not reproduce it...

It's actually the logic i had before changing to pausePreview() and resumePreview() but in my case this was causing more trouble to dispose the camera and re init it.
If this is the only solution, i will not change anything and it's not that bad since it doesn't crash the app and the camera is still working, not frozen or anything so i prefer having this error rather the ones i had with the other logic.

Can you please elaborate on this ? Are you saying changing to pausePreview() and resumePreview() is causing the said issue ?

If this is the only solution,

Which solution are you referring to ?

Probably, because i was using the dispose() and re initialize() before switching to pausePreview() and resumePreview()

Which solution are you referring to ?

The solution would be to let the pausePreview() and resumePreview() despite having rarely the above error.
When i was not using this, i had crashes that i have made in other separate issues.
So i prefer having this error than the crashes i had when using dispose().

Would be good if there's a pattern or repro code you can come up with using pausePreview() and resumePreview() along with dispose() and then initialize that would lead to IllegalStateException.

It actually depends on the android version, i have got ARN on some phones that have Android 11 and above.
It might be linked to #95921.

My code is this one :

@override
  void initState() {
    super.initState();
    // Allows to listen to the application lifecycle states.
    WidgetsBinding.instance!.addObserver(this);
    WidgetsBinding.instance!.addPostFrameCallback((Duration timeStamp) {
      _cameraViewModel.initCamera();
    });
  }

  @override
  void dispose() {
    _cameraViewModel.disposeCamera();
    WidgetsBinding.instance!.removeObserver(this);
    super.dispose();
  }

  @override
  void didChangeAppLifecycleState(AppLifecycleState state) {
    super.didChangeAppLifecycleState(state);
    switch (state) {
      case AppLifecycleState.resumed:
        _cameraViewModel.resumeCamera();
        break;
      case AppLifecycleState.inactive:
        _cameraViewModel.pauseCamera();
        break;
      case AppLifecycleState.paused:
        break;
      case AppLifecycleState.detached:
        break;
    }
  }

And in CameraViewModel :


Future<void> initCamera() async {
    PermissionStatus status = await Permission.camera.request();
    if (status.isGranted) {
      List<CameraDescription> availableCams = await availableCameras();
      _cameras.clear();
      _cameras.addAll(availableCams);
      cameraController = CameraController(_cameras.first, ResolutionPreset.veryHigh, enableAudio: false);
      if (!cameraController!.value.isInitialized) {
        await cameraController!.initialize();
        cameraController!.setFlashMode(FlashMode.off);
      }
    } else {
      if (status.isPermanentlyDenied) {
        AppSettings.openAppSettings();
      }
    }
  }

  void disposeCamera() {
    if (cameraController != null && cameraController!.value.isInitialized) {
      cameraController!.dispose();
      cameraController = null;
    }
  }

  void resumeCamera() {
    if (cameraController != null) {
      if (cameraController!.value.isPreviewPaused) {
        cameraController!.resumePreview();
      } else {
        initCamera();
      }
    }
  }

  void pauseCamera() {
    if (cameraController != null && cameraController!.value.isInitialized) {
      cameraController!.pausePreview();
    }
  }

Thanks for above code. I am trying to inculcate that into camera plugin example. Can you also try to do the same using the plugin example and see if you are able to replicate it ?

You get the above error when tweaking around with the pause button, the start video recording and the stop video recording (all the time if you do it a bit fast).

Regarding the lifecycle i was not able to reproduce this issue using the example code yet, i had much time lately i will try better a bit later.

From above log, I see couple of different exceptions:

java.lang.RuntimeException: stop failed. seems similar to #79306

Unhandled Exception: CameraException(INVALID_PATH. looks similar to #86169
#96270

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
