How to get the current location in Google Maps Android API v2?

Question

Using

mMap.setMyLocationEnabled(true)

can set the myLocation layer enable.
But the problem is how to get the myLocation when the user

Answer 1

Ensure that you have turned ON the location services on the device. Else you won't get any location related info.

This works for me,

    map = ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
    map.setMyLocationEnabled(true);
    GoogleMap.OnMyLocationChangeListener myLocationChangeListener = new GoogleMap.OnMyLocationChangeListener() {
        @Override
        public void onMyLocationChange (Location location) {
           LatLng loc = new LatLng (location.getLatitude(), location.getLongitude());
           map.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f));
        }
    };
    map.setOnMyLocationChangeListener(myLocationChangeListener);

}

Answer 2

To get the location when the user clicks on a button call this method in the onClick-

void getCurrentLocation() {
    Location myLocation  = mMap.getMyLocation();
    if(myLocation!=null)
    {
        double dLatitude = myLocation.getLatitude();
        double dLongitude = myLocation.getLongitude();
        Log.i("APPLICATION"," : "+dLatitude);
        Log.i("APPLICATION"," : "+dLongitude);
        mMap.addMarker(new MarkerOptions().position(
                new LatLng(dLatitude, dLongitude)).title("My Location").icon(BitmapDescriptorFactory.fromBitmap(Utils.getBitmap("pointer_icon.png"))));
        mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(dLatitude, dLongitude), 8));

    }
    else
    {
        Toast.makeText(this, "Unable to fetch the current location", Toast.LENGTH_SHORT).show();
    }

}

Also make sure that the

setMyLocationEnabled

is set to true.

Try and see if this works...

Answer 3

try this

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                == PackageManager.PERMISSION_GRANTED) {
    mMap.setMyLocationEnabled(true);
} else {
    // Show rationale and request permission.
}

Answer 4

try this

LocationManager service = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = service.getBestProvider(criteria, false);
Location location = service.getLastKnownLocation(provider);
LatLng userLocation = new LatLng(location.getLatitude(),location.getLongitude());

Answer 5

the accepted answer works but some of the used methods are now deprecated so I think it is best if I answer this question with updated methods.

this is answer is completely from this guide on google developers

so here is step by step guide:

1. implement all this in your map activity

   MapActivity extends FragmentActivity implements OnMapReadyCallback, GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks

2. in your onCreate:

   private GoogleMap mMap;
   private Context context;
   private TextView txtStartPoint,txtEndPoint;
   private GoogleApiClient mGoogleApiClient;
   private Location mLastKnownLocation;
   private LatLng mDefaultLocation;
   private CameraPosition mCameraPosition;
   private boolean mLocationPermissionGranted;
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_maps);
   context = this;
   mGoogleApiClient = new GoogleApiClient.Builder(this)
           .enableAutoManage(this /* FragmentActivity */,
                   this /* OnConnectionFailedListener */)
           .addConnectionCallbacks(this)
           .addApi(LocationServices.API)
           .addApi(Places.GEO_DATA_API)
           .addApi(Places.PLACE_DETECTION_API)
           .build();
   mGoogleApiClient.connect();
   }
   

3. in your onConnected :

   SupportMapFragment mapFragment = (SupportMapFragment)     getSupportFragmentManager()
           .findFragmentById(map);
   mapFragment.getMapAsync(this);
   

4. in your onMapReady :

   @Override
   public void onMapReady(GoogleMap googleMap) {
   mMap = googleMap;
   
   // Do other setup activities here too, as described elsewhere in this tutorial.
   
   // Turn on the My Location layer and the related control on the map.
   updateLocationUI();
   
   // Get the current location of the device and set the position of the map.
   getDeviceLocation();
   }
   

5. and these two are methods in onMapReady :

   private void updateLocationUI() {
     if (mMap == null) {
       return;
   }
   
   if (ContextCompat.checkSelfPermission(this.getApplicationContext(),
           android.Manifest.permission.ACCESS_FINE_LOCATION)
           == PackageManager.PERMISSION_GRANTED) {
       mLocationPermissionGranted = true;
   }
   
   if (mLocationPermissionGranted) {
       mMap.setMyLocationEnabled(true);
       mMap.getUiSettings().setMyLocationButtonEnabled(true);
   } else {
       mMap.setMyLocationEnabled(false);
       mMap.getUiSettings().setMyLocationButtonEnabled(false);
       mLastKnownLocation = null;
   }
   }
   
   private void getDeviceLocation() {
   if (ContextCompat.checkSelfPermission(this.getApplicationContext(),
           android.Manifest.permission.ACCESS_FINE_LOCATION)
           == PackageManager.PERMISSION_GRANTED) {
       mLocationPermissionGranted = true;
   }
   
   if (mLocationPermissionGranted) {
       mLastKnownLocation = LocationServices.FusedLocationApi
               .getLastLocation(mGoogleApiClient);
   }
   
   // Set the map's camera position to the current location of the device.
   float DEFAULT_ZOOM = 15;
   if (mCameraPosition != null) {
       mMap.moveCamera(CameraUpdateFactory.newCameraPosition(mCameraPosition));
   } else if (mLastKnownLocation != null) {
       mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(
               new LatLng(mLastKnownLocation.getLatitude(),
                       mLastKnownLocation.getLongitude()), DEFAULT_ZOOM));
   } else {
       Log.d("pouya", "Current location is null. Using defaults.");
       mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(mDefaultLocation, DEFAULT_ZOOM));
       mMap.getUiSettings().setMyLocationButtonEnabled(false);
   }
   }
   

this is very fast , smooth and effective. hope this helps

Answer 6

I would rather use FusedLocationApi since OnMyLocationChangeListener is deprecated.

First declare these 3 variables:

private LocationRequest  mLocationRequest;
private GoogleApiClient  mGoogleApiClient;
private LocationListener mLocationListener;

Define methods:

private void initGoogleApiClient(Context context)
{
    mGoogleApiClient = new GoogleApiClient.Builder(context).addApi(LocationServices.API).addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks()
    {
        @Override
        public void onConnected(Bundle bundle)
        {
            mLocationRequest = LocationRequest.create();
            mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
            mLocationRequest.setInterval(1000);

            setLocationListener();
        }

        @Override
        public void onConnectionSuspended(int i)
        {
            Log.i("LOG_TAG", "onConnectionSuspended");
        }
    }).build();

    if (mGoogleApiClient != null)
        mGoogleApiClient.connect();

}

private void setLocationListener()
{
    mLocationListener = new LocationListener()
    {
        @Override
        public void onLocationChanged(Location location)
        {
            String lat = String.valueOf(location.getLatitude());
            String lon = String.valueOf(location.getLongitude());
            Log.i("LOG_TAG", "Latitude = " + lat + " Longitude = " + lon);
        }
    };

    LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, mLocationListener);
}

private void removeLocationListener()
{
    LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, mLocationListener);
}

• initGoogleApiClient() is used to initialize GoogleApiClient object
• setLocationListener() is used to setup location change listener
• removeLocationListener() is used to remove the listener

Call initGoogleApiClient method to start the code working :) Don't forget to remove the listener (mLocationListener) at the end to avoid memory leak issues.
