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) {}
The FusedLocationProviderClient provides several methods to retrieve device location information. Choose from one of the following, depending on your app's use case: getLastLocation() gets a location estimate more quickly and minimizes battery usage that can be attributed to your app.
The fused location provider is a location API in Google Play services that intelligently combines different signals to provide the location information that your app needs.
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:
Wait until the Google Map is ready
Request the Location permission at runtime if needed
Request location updates once the permission is granted
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______"/>

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):
