Google Api Client give null onConnected method and getting LastLocation also null

Question

Google client implementation is given below:

   if (mGoogleApiClient == null) {
                mGoogleApiClient = new GoogleApiClient.Builder(this)
                        .addConnectionCallbacks((GoogleApiClient.ConnectionCallbacks) this)
                        .addOnConnectionFailedListener((GoogleApiClient.OnConnectionFailedListener) this)
                        .addApi(LocationServices.API)
                        .build();
            }

onStart i am connecting GoogleApiClient

  @Override
protected void onStart() {
    super.onStart();
    if (mGoogleApiClient != null)
        mGoogleApiClient.connect();
}

till here everything is fine but on connected method its return null

@Override
public void onConnected(Bundle bundle) {
    if (bundle != null)// always null
        Log.e(TAG, bundle.toString());
}

Getting code for location on onClick of floating button after connected to google api client

 //Floating Action Button
            floatingActionButton.setOnClickListener(new View.OnClickListener() {
                                                        @TargetApi(Build.VERSION_CODES.M)
                                                        @Override
                                                        public void onClick(View v) {
                                                            //To Check Runtime Permission
                                                            checkRuntimePermission();
                                                            mMap.clear();
                                                            mMap.setMyLocationEnabled(true);

                                                            mLocationRequest = new LocationRequest();
                                                            mLocationRequest.setInterval(50);
                                                            mLocationRequest.setFastestInterval(10);
                                                            mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);


                                                            mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);

                                                            if (!Utils.GPS_SERVICE(mContext)) {
                                                                Utils.isGPSOnline(mContext);
                                                            }

                                                            if (mLastLocation != null) {
                                                                double lon = mLastLocation.getLongitude();
                                                                double lat = mLastLocation.getLatitude();
                                                                LatLng latlng = new LatLng(lat, lon);
                                                                mMap.addMarker(new MarkerOptions().position(latlng).title("My_location"));

                                                                //TO move the marker when user enter any Location
                                                                mMap.moveCamera(CameraUpdateFactory.newLatLng(latlng));
                                                                mMap.animateCamera(CameraUpdateFactory.zoomTo(15));
                                                            }
                                                        }
                                                    }

also post your full code and i want to see where u initiate the google api client — Quick learner, Apr 05 '17 at 05:59
@phanVanLinh i want to know that i have connected to the client or not — Nikhil Sharma, Apr 05 '17 at 06:02
@NikhilSharma if the callback return to `onConnected` that mean GoogleApiClient is connected (bundle = null or != null is not important). if it is not connect, callback will return to `onConnectionFailed` — Linh, Apr 05 '17 at 06:05
@phan Van Linh yeah your right but even thn my last location is null and earlier this code working fine suddenly i dont knw what hppn — Nikhil Sharma, Apr 05 '17 at 06:06
@NikhilSharma when/where do you call `getLastLocation`, make sure you get it after GoogleApiClient is connected — Linh, Apr 05 '17 at 06:09
@phan Van linh after my maps get loaded after that onButtonClick event i am requesting for my location\ — Nikhil Sharma, Apr 05 '17 at 06:11
@NikhilSharma are you sure at this time, GoogleApiClient is connected? — Linh, Apr 05 '17 at 06:14

If onConnected() getting called, you GoogleApiClient is okay.

Why bundle is null?

Have a look at this method -

public abstract void onConnected (Bundle connectionHint)

Contents of the connectionHint Bundle are defined by the specific services. May be null if no content is provided by the service.

Thanks but still the same this happing :( – Nikhil Sharma Apr 05 '17 at 06:04
@NikhilSharma returning bundle should not be a problem because it is being managed bu Google play services. Look at the edited answer. – Paresh P. Apr 05 '17 at 06:15
yeah your right my GoogleApiClient its ok but onConnected retruning null as well as my LastLocation always null – Nikhil Sharma Apr 05 '17 at 06:17
Wrap whole code of `onClick()` with `if(mGoogleApiClient.isConnected())` and check if client is null or what? Further make sure runtime permissions are granted as well. – Paresh P. Apr 05 '17 at 06:26
Yeah i have debug it m Googleclient is connected and permissions also granted but using android 4.4 version – Nikhil Sharma Apr 05 '17 at 06:30
Thanks for your help but now everything is working fine i dont knw what this happing – Nikhil Sharma Apr 05 '17 at 06:55
I have the same problem, I'm getting null connectionHint, what is the solution for this situation? – Andrey Solera Sep 26 '17 at 22:36

Try

if (mGoogleApiClient == null) {
            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .addConnectionCallbacks((GoogleApiClient.ConnectionCallbacks) this)
                    .addOnConnectionFailedListener((GoogleApiClient.OnConnectionFailedListener) this)
                    .addApi(LocationServices.API)
.enableAutoManage(activityContext, this) // this - for implementing Interface
                    .build();
        }

what do you mean by "activityContext" – Nikhil Sharma Apr 05 '17 at 05:57
If your activity is MainActivity then context would be `MainActivity.this` – Wilson Christian Apr 05 '17 at 05:58
this is not working also and earlier everything working fine but suddenly its not working – Nikhil Sharma Apr 05 '17 at 06:03
you should debug it in every callback – Quick learner Apr 05 '17 at 07:02

Remove this condition as well if (mGoogleApiClient == null) and pass this in callbacks

                mGoogleApiClient = new GoogleApiClient.Builder(this)
                        .addConnectionCallbacks(this)
                        .addOnConnectionFailedListener(this)
                        .addApi(LocationServices.API)
                        .build();
