android - Autocomplete-Adapter: java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification -
i'm out of ideas on here. have autocompletetextview adapter power suggestions. search words geographic regions.
i have 2 kinds of autocomplete-suggestions: searched regions (search history, locally saved) , automplete api called on the network.
sometimes when type in word fast receive following error:
java.lang.illegalstateexception: content of adapter has changed listview did not receive notification. make sure content of adapter not modified background thread, ui thread. i understand exception in general (the underlying data of adapter should not changed without calling notifydatasetchanged() on adapter) don't see i'm doing wrong here.
as far understand getfilter() method running on ui thread , automplete() method running asynchronously.
here's adapter , can see the autocompregions changed in getfilter() method (ui thread) , notifydatasetchanged() called after.
also, had same problem when using regions retrieved via api , didn't have addition of locally saved region objects, doesn't have those.
any suggestions?
