Для Android 2.3.3 (или любого другого API ниже 16) мое приложение работает без каких-либо ошибок.
Для устройств Android 4.1 (API 16) и выше я получаю эту ошибку (приложение имеет минимальный уровень API 10):
java.lang.NullPointerException E/AndroidRuntime(1066): at at.kopp.huettenapp.MasterActivity.onCreateOptionsMenu(MasterActivity.java:347)
