AutoCompleteTextView over MapsFragment
In my app I have a RelativeLayout->fragment(SupportMapFragment)|Relativelayout->AutoCompleteTextView
The search should do what Google Maps' search bar should do and return a dropdown list of locations from my search keyword. After I finish typing and a few second delay, my app crashes with the error:

I understand that this may be because I am not able to inflate a view over a fragment(https://stackoverflow.com/a/19815266/5336014). Is this something that is fixable?

Also, I got this error solving another problem which can be found at this link: Filter json results for Autocomplete adapter
Thanks in advance.
Solution
The two argument constructor of ArrayAdapter i.e ArrayAdapter (Context context, int resource) expects layout resource and not id of a TextView.
You are passing id of your AutoCompleteTextView that it tries to inflate but fails as there is no layout with that id. Change the line where you instantiate your adapter to:
autoCompView.setAdapter(
new GooglePlacesAutocompleteAdapter(this,
android.R.layout.simple_list_item_1));
