Demo using Fragment

[skywaydave]

Hi There,

I'm embedding the cameraview in a Fragment (within an Activity) and have run into the following exception when mCameraView.start() is called in onResume():

java.lang.IllegalStateException: Session has been closed; further changes are illegal.

I'm running on a Nexus 6P with Android 6.0.

Is there a working example that illustrates how to do this?

Thanks

I haven't tried this myself yet. We should definitely enhance the demo app with more use cases like this.

This is how I made it work in a Fragment:

   @Override
    public void onResume() {
        super.onResume();

        if (cameraView != null && isCapturing) {
            cameraView.start();
        }
    }

    @Override
    public void onPause() {
        if (cameraView != null && isCapturing)
            cameraView.stop();

        super.onPause();
    }

The flag is manually set when calling start/stop.
