title: Are Android adapters asynchronous?
body: <p>I looked at <a href="https://developers.google.com/places/training/autocomplete-android" rel="nofollow">this example</a> from Google, it's an adapter on an <code>AutoCompleteTextView</code> that makes a network call to an API to retrieve auto-complete suggestions.</p>
  
  <p>It doesn't use <code>AsynkTask</code> or threads, but doesn't give <code>StrictMode</code> warnings and doesn't lock the UI when there's no internet connection and I'm wondering why.</p>
  
  <p>Is the <code>ArrayAdapter</code> itself asynchronous?</p>
