Я не знаю, в чем проблема с моим кодом, я пытаюсь определить маяк, используя https://altbeacon.github.io/android-beacon-library извините за плохой Engli sh, и я новичок в разработке мобильных приложений.

, и я использую этот код для начать мой BeaconActivity
Intent intent = new Intent(this, BeaconActivity.class);
