I'm using the qReader library which according to my logs works as intended, contrary to the big error log, except when trying to change fragment using viewPager.setCurrentItem(0) in the MainFragment. I'm hoping someone recognises these errors and can tell me if it's relevant to my problem of changing fragment. If no one recognises the errors then I'm guessing they're library specific and Ill open an issue on the library's github.

It's not necessary to call CameraSource.stop() from the UI thread, but due to an implementation detail it should not be called from the thread that executes receiveDetections. The stop() code waits for this thread to finish, so calling it this way would create a deadlock.
Does CameraSource.stop() require to be called from UI Thread?
I had to release/stop the CameraSource object from the UI Thread to avoid the deadlock mentioned above.
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
cameraSource.stop();
cameraRunning = false;
}
});
