Hallo ChampS,
nee ich hab das Filter nachher eingesetzt. Das funktioniert auch nicht ohne das. Der Witz ist ich poste mal einen anderen Versuch von mir. Da klappt es auf einmal ohne Fehlermeldung. Und ehrlich gesagt, fällt mir da kein unterschied zum anderen Code auf.

if (id == R.id.action_settings) {

return super.onOptionsItemSelected(item);

}Aufruf von meiner Main auf die zweite Activity tut.

}Aufruf von meiner secActivity auf die ThirdActivity tut auch.
Das Problem ist, ich kann mein anderes Programm so nicht fortsetzen
