This happens when application goes in paused state while scanning qr code and just resume the application it will crash

This is the code for paused state and resume state

@OverRide
protected void onPause() {
super.onPause();

    if (hasCameraPermission) {

        // Cleanup in onPause()
        // --------------------
        qrEader.releaseAndCleanup();
    }
}

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

    if (hasCameraPermission) {

        // Init and Start with SurfaceView
        // -------------------------------
        qrEader.initAndStart(mySurfaceView);

    }
}
