Fatal exception

[Sp4Rx]

Unable to start preview and I have no clue why. This worked on most of the phones I have tested but on my crashlytics I'm getting this crash.

Fatal Exception: java.lang.RuntimeException: startPreview failed

Maybe the user disabled the camera permission. Please paste more info about user device, android ver and so on if you have.

You are right its due to the permission. Though its not a crash. I think the logs which I have mentioned before is due to this.

Actually I'm checking permission at my fragment's onResume and then calling mCameraView.resumePreview();(this is extended from your CameraGLSurfaceView). And in your CameraGLSurfaceView's onSurfaceCreated you are doing cameraInstance().tryOpenCamera(null, facing) . So for the first time it will give an error if there is no permission.

Get it. The app in the repo is just a demo. You can do more stable check before the camera is required~

This issue can be closed. The problem was different. You have a singleton camera. So before closing my fragment I need to call your release method at onStop.

As I'm not calling it the next time I'm opening the camera it was already busy and cased the crash.
