protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    PlacesAutocompleteTextView placesAutocomplete=(PlacesAutocompleteTextView)findViewById(R.id.places_autocomplete);


    placesAutocomplete.setOnPlaceSelectedListener(
            new OnPlaceSelectedListener() {
                @Override
                public void onPlaceSelected(final Place place) {
                    // do something awesome with the selected place
                }
