How to get current Location in GoogleMap using FusedLocationProviderClient

I want to get periodic (say every 2 minutes) current location updates for this I'm following official documentation, I wrote this code but its not giving current location updates every two minutes even specified in LocationRequest object that I'm passing in requestLocationUpdates(), here is code:

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback,
    GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener{

private FusedLocationProviderClient FusedLocationClient;
private GoogleApiClient mGoogleApiClient;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    if (mGoogleApiClient == null) {
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }

 SupportMapFragment map = 
  getSupportFragmentManager().findFragmentById(R.id.map));

  map.getMapAsync(this);

  FusedLocationClient LocationServices.getFusedLocationProviderClient(this);
}


@Override
public void onConnected(Bundle bundle) {
    FusedLocationClient.getLastLocation()
            .addOnSuccessListener(this, new OnSuccessListener<Location>() {
                @Override
                public void onSuccess(Location location) {

                    if (location != null) {
                        Log.i("MainActivity ", "" + location.getLongitude()) 
                    }
                }
            });
FusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
FusedLocationClient.requestLocationUpdates(requestLocation(), 
new LocationCallback(){
        @Override
        public void onLocationResult(LocationResult locationResult) {
            for (Location location : locationResult.getLocations()) {
               Log.i("MainActivity ", "" + location.getLongitude());
               //not getting current location updates every 2 minutes
            }
        };

    },null);

}

@Override
public void onConnectionSuspended(int i) {}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {}

This is similar to my other answer here, updated to use the recently introduced FusedLocationProviderClient class.

In order to use a FusedLocationProviderClient in conjunction with a Google Map:

  1. Wait until the Google Map is ready

  2. Request the Location permission at runtime if needed

  3. Request location updates once the permission is granted

  4. Update the Google Map once the user's location is obtained

First ensure that you're using at least version 11 of Google Play Services, as older versions don't have the FusedLocationProviderClient class (newer versions will work as well):

dependencies {
      implementation 'com.google.android.gms:play-services-maps:17.0.0'
      implementation 'com.google.android.gms:play-services-location:17.0.0'
    //........
}

Note that the FusedLocationProviderClient is present in version 11.0.2, but due to bugs in the initial implementation, it's recommended that you only use this class on 11.6.0 and later. From the documentation:

Note: It's recommended to use Google Play services version 11.6.0 or higher, which includes bug fixes for this class.

Add the location permissions in the AndroidManifest.xml file, inside the manifest tag and outside of the application tag:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

Add the API key to the AndroidManifest.xml inside the application tag:

    <meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="AIza___YOUR_KEY_HERE______"/>

Kotlin

Here is the full Activity class in Kotlin:

Extra note regarding AndroidX

If you are using AndroidX, you might need to add these lines to your gradle.properties file (see here for more info):

android.useAndroidX=true
android.enableJetifier=true

 mLocationCallback = new LocationCallback() {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            super.onLocationResult(locationResult);
            currentLocation = locationResult.getLastLocation();

        }
    };

this work for me.
