I am explaining  How to get current location and Directly move to the camera to current location with assuming that you have implemented map-v2  For more details  You can refer official doc   Add location service in gradle  implementation  com google android gms play-services-location 11 0 1    Add location permission in manifest file   lt uses-permission android name  android permission ACCESS FINE LOCATION    gt   lt uses-permission android name  android permission ACCESS COARSE LOCATION    gt    Make sure you ask for RunTimePermission  I am using Ask-Permission for that  Its easy to use   Now refer below code to get the current location and display it on a map   private FusedLocationProviderClient mFusedLocationProviderClient    Override public void onCreate  Nullable Bundle savedInstanceState            super onCreate savedInstanceState           mFusedLocationProviderClient   LocationServices                  getFusedLocationProviderClient getActivity         private void getDeviceLocation             try               if  mLocationPermissionGranted                    Task lt Location gt  locationResult   mFusedLocationProviderClient getLastLocation                    locationResult addOnCompleteListener new OnCompleteListener lt Location gt                           Override                     public void onComplete  NonNull Task lt Location gt  task                            if  task isSuccessful                                     Set the map s camera position to the current location of the device                              Location location   task getResult                                LatLng currentLatLng   new LatLng location getLatitude                                        location getLongitude                                 CameraUpdate update   CameraUpdateFactory newLatLngZoom currentLatLng                                      DEFAULT ZOOM                               googleMap moveCamera update                                                                                               catch  SecurityException e                Log e  Exception   s   e getMessage                   When user granted location permission call above getDeviceLocation   method  private void updateLocationUI             if  googleMap    null                return                    try               if  mLocationPermissionGranted                    googleMap setMyLocationEnabled true                   googleMap getUiSettings   setMyLocationButtonEnabled true                   getDeviceLocation                  else                   googleMap setMyLocationEnabled false                   googleMap getUiSettings   setMyLocationButtonEnabled false                           catch  SecurityException e                Log e  Exception   s   e getMessage

make sure you have these permissions    lt uses-permission android name  android permission ACCESS FINE LOCATION   gt   lt uses-permission android name  android permission ACCESS COARSE LOCATION   gt    Then make some activity and register a LocationListener  package com example location   import android content Context  import android location Location  import android location LocationListener  import android location LocationManager  import android os Bundle  import android view View  import com actionbarsherlock app SherlockFragmentActivity  import com google android gms maps CameraUpdate  import com google android gms maps CameraUpdateFactory  import com google android gms maps GoogleMap  import com google android gms maps SupportMapFragment  import com google android gms maps model LatLng   public class LocationActivity extends SherlockFragmentActivity implements LocationListener       private GoogleMap map  private LocationManager locationManager  private static final long MIN TIME   400  private static final float MIN DISTANCE   1000    Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout map       map     SupportMapFragment  getSupportFragmentManager   findFragmentById R id map   getMap         locationManager    LocationManager  getSystemService Context LOCATION SERVICE       locationManager requestLocationUpdates LocationManager NETWORK PROVIDER  MIN TIME  MIN DISTANCE  this     You can also use LocationManager GPS PROVIDER and LocationManager PASSIVE PROVIDER             Override public void onLocationChanged Location location        LatLng latLng   new LatLng location getLatitude    location getLongitude         CameraUpdate cameraUpdate   CameraUpdateFactory newLatLngZoom latLng  10       map animateCamera cameraUpdate       locationManager removeUpdates this       Override public void onStatusChanged String provider  int status  Bundle extras        Override public void onProviderEnabled String provider        Override public void onProviderDisabled String provider          map xml   lt  xml version  1 0  encoding  utf-8   gt   lt fragment xmlns android  http   schemas android com apk res android  android id    id map  android layout width  match parent  android layout height  match parent  class  com google android gms maps SupportMapFragment   gt

The above answer is not according to what Google Doc Referred for Location Tracking in Google api v2   I just followed the official tutorial and ended up with this class that is fetching the current location and centring the map on it as soon as i get that   you can extend this class to have LocationReciever to have periodic Location Update  I just executed this code on api level 7  http
