The app has a fragment with recyclerview and FAB . Clicking FAB opens a dialog where the user enters addresses, among other information.
The address input fields are of type AutoCompleteTextView and receive address suggestions as the user enters the information.
This was done using GoogleApiClient with GEO_DATA_API , according to the following code:
public class RecyclerFragment extends Fragment
implements AlertDialog.OnClickListener,
GoogleApiClient.OnConnectionFailedListener,
GoogleApiClient.ConnectionCallbacks {
private static final String TAG = "RecyclerFragment";
RecyclerView recyclerView;
RunDbHelper runDbHelper;
RecyclerViewAdapter recyclerViewAdapter;
private OnOkButtonListener mCallback;
private GoogleApiClient mGoogleApiClient;
private PlaceArrayAdapter mPlaceArrayAdapter;
private static final int GOOGLE_API_CLIENT_ID = 0;
private static final LatLngBounds BOUNDS_MOUNTAIN_VIEW = new LatLngBounds(
new LatLng(37.398160, -122.180831), new LatLng(37.430610, -121.972090));
private static LatLngBounds BOUNDS_AUTOCOMPLETE;
public RecyclerFragment() {
this.mCallback = null;
}
public void setAutocompleteBounds(LatLng centerLatLng){
if (centerLatLng!= null && !centerLatLng.toString().isEmpty()){
Double latSW, lngSW, lngNE, latNE;
latSW = centerLatLng.latitude-.5;
lngSW = centerLatLng.latitude-.5;
lngNE = centerLatLng.latitude+.5;
latNE = centerLatLng.latitude+.5;
BOUNDS_AUTOCOMPLETE = new LatLngBounds(
new LatLng(latSW, lngSW), new LatLng(latNE, lngNE));
} else {
BOUNDS_AUTOCOMPLETE = new LatLngBounds(
new LatLng(37.398160, -122.180831), new LatLng(37.430610, -121.972090));
}

After entering the information, they go to the database and pro recyclerview, forming a list of cardviews.
Each cardview has an edit button. At the touch of a button, a dialog opens with the form. editing. At this time, I'd like to use the same address suggestion feature.
All editing is ready. Only this GoogleApiClient will work ...

I tried to follow the RecyclerFragment template, but something is wrong and I can not instantiate GoogleApiClient in onCreateView method.
Note that I was using Google Places WebService and with this API it works, but it should not be used in app in production, so I'm switching to Google Places API for Android.
Tomara, can you help me.
