autocompletetextview - Are Android adapters asynchronous? -

-

i looked @ this example google, it's adapter on autocompletetextview makes network call api retrieve auto-complete suggestions.

it doesn't use asynktask or threads, doesn't give strictmode warnings , doesn't lock ui when there's no internet connection , i'm wondering why.

is arrayadapter asynchronous?

filtering perfomed asynchronously.

filtering operations performed calling filter(charsequence) or filter(charsequence, android.widget.filter.filterlistener) performed asynchronously. when these methods called, filtering request posted in request queue , processed later. call 1 of these methods cancel previous non-executed filtering request.
