how to get current location in google map android

android, google-maps

Solution

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
                }
            }
        });

Problem

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)); ```
