Show my current location in the Google Map

Question

Finally I succeed to display the map,Now,I want to show my current location, I tried by using these code but it didn't work when I clicked the my location button in the top right corner.

AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="com.example.hp.testmap.MAPS_RECEIVE"></uses-permission>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

<permission
    android:name="com.example.hp.testmap.permission.MAPS_RECEIVE"
    android:protectionLevel="signature"/>

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true"/>

MapsActivity.java

public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    mMap.setMyLocationEnabled(true);
   if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

       LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

       Criteria criteria = new Criteria();

       String provider = locationManager.getBestProvider(criteria, true);

       Location myLocation = locationManager.getLastKnownLocation(provider);

       mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);

        double latitude = myLocation.getLatitude();

        double longitude = myLocation.getLongitude();

        LatLng latLng = new LatLng(latitude, longitude);

        mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));

        mMap.animateCamera(CameraUpdateFactory.zoomTo(20));
        return;
    }

}

private GoogleApiClient mGoogleApiClient;
private GoogleMap mMap;

Implement this listeners:

LocationListener, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener

onCreateView or onCreate method:

if (mGoogleApiClient == null) {
    mGoogleApiClient = new GoogleApiClient.Builder(mActivity)
        .addApi(LocationServices.API).addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this).build();
    mGoogleApiClient.connect();
}

@Override Methods:

@Override
public void onConnected(@Nullable Bundle bundle) {
    if (ContextCompat.checkSelfPermission(mActivity, android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(mActivity, android.Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
        Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
        if (mLastLocation != null)
            onLocationChanged(mLastLocation);
        return;
    }
}

@Override
public void onLocationChanged(Location location) {
    if (location != null) {
        mMap.moveCamera(CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(),location.getLongitude())));
        mMap.animateCamera(CameraUpdateFactory.zoomTo(6), 5000, null);
    }
}

Hope your task done.

Use this Code for Current Location:

googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);

    // TODO: Consider calling
    //    ActivityCompat#requestPermissions
    // here to request the missing permissions, and then overriding
    //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
    //                                          int[] grantResults)
    // to handle the case where the user grants the permission. See the documentation
    // for ActivityCompat#requestPermissions for more details.
    return;
}
googleMap.setMyLocationEnabled(true);

Use following code:

//Zoom to the current location
public Location getMyLocation() {
    LocationManager locationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
    Criteria criteria = new Criteria();

    Location location = locationManager.getLastKnownLocation(locationManager.getBestProvider(criteria, false));
    if (location != null) {
        map.animateCamera(CameraUpdateFactory.newLatLngZoom(
                new LatLng(location.getLatitude(), location.getLongitude()), 13));

        CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(new LatLng(location.getLatitude(), location.getLongitude()))      // Sets the center of the map to location user
                .zoom(17)                   // Sets the zoom
                .bearing(90)                // Sets the orientation of the camera to east
                .tilt(40)                   // Sets the tilt of the camera to 30 degrees
                .build();                   // Creates a CameraPosition from the builder
        map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

    }

    return location;
}

Then call this method insode your onCreate

Hope this helps :)
