how to get current location in google map android

Actually my problem is I am not getting current location latitude and longitude I tried so many ways.I know that this question already asked in SO I tried that answers also still I didn't get answer.Please help me Code:

    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMap();

        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }
    googleMap.setMyLocationEnabled(true);
    Location myLocation = googleMap.getMyLocation();  //Nullpointer exception.........
    LatLng myLatLng = new LatLng(myLocation.getLatitude(),
            myLocation.getLongitude());

    CameraPosition myPosition = new CameraPosition.Builder()
            .target(myLatLng).zoom(17).bearing(90).tilt(30).build();
    googleMap.animateCamera(
        CameraUpdateFactory.newCameraPosition(myPosition));

Solution 1:

Please check the sample code for the Google Maps Android API v2. Using this will solve your problem.

private void setUpMapIfNeeded() {
    // Do a null check to confirm that we have not already instantiated the map.
    if (mMap == null) {
        // Try to obtain the map from the SupportMapFragment.
        mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
        mMap.setMyLocationEnabled(true);
        // Check if we were successful in obtaining the map.
        if (mMap != null) {
            mMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
                @Override
                public void onMyLocationChange(Location arg0) {
                    mMap.addMarker(new MarkerOptions().position(new LatLng(arg0.getLatitude(), arg0.getLongitude())).title("It's Me!"));
                }
            });
        }
    }
}

Call this function in onCreate function.

Update:

The method mMap.setOnMyLocationChangeListener is now deprecated, you need to use the FusedLocationProviderClient now.

private FusedLocationProviderClient fusedLocationClient;
@Override
protected void onCreate(Bundle savedInstanceState) {
    fusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
}

To request the last known location, call the getLastLocation() method. The following code snippet illustrates the request and a simple handling of the response:

fusedLocationClient.getLastLocation()
        .addOnSuccessListener(this, new OnSuccessListener<Location>() {
            @Override
            public void onSuccess(Location location) {
                // Got last known location. In some rare situations this can be null.
                if (location != null) {
                    // Logic to handle location object
                }
            }
        });

Solution 2:

I think that better way now is:

Location currentLocation = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);
