Ich erhalte einen Fehler in meinem Code mit diesem Logcat:

Ich denke, dass das Problem die Autocompletetextview ist, die ich verursachte. Ich habe das Array zugeordnet, um die Position des Arrays zu ermitteln, wenn ich während des Suchvorgangs in das Dropdown-Menü klicke.

In Zeile 88 habe ich Folgendes:

ArrayMap<String, Integer>myArrayMap = new ArrayMap<String, Integer>();

Der Absturz scheint nur mit Android 4.1 Version zu sein. Gibt es eine Inkompatibilität?
