myślę, że problem jest autocompletetextview i stworzył. Zmapowałem tablicę, aby uzyskać pozycję tablicy po kliknięciu menu rozwijanego podczas wpisywania tego, co chcę wyszukać.

Na linii 88 mam to:

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

Katastrofa wydaje się być tylko z Android 4.1 wersji. Czy jest jakaś niezgodność?

Answer 1

ArrayMap została wprowadzona w poziomie Api 19, ale został wydany w bibliotece v4 kompatybilności, więc to byłoby na tyle, aby zamiast zmienić import do android.support.v4.util.ArrayMap z android.util.ArrayMap
