In your current code, the current location is only updated when you click the "enable button".
However, in that code, you are adding a new OnClickListener to that button every time the location is updated. Instead you should define the OnClickListener to publish the current value of latLng (which in the code below I renamed to mLatLng to follow conventions).
// Firebase services
private FirebaseAuth mAuth;
private FirebaseDatabase mDatabase;
// Firebase objects
private FirebaseUser mUser;
private DatabaseReference mUserRef;
// Java objects
private SupportMapFragment mMapFragment;
private LatLng mLatLng;
private String mUserId;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps2);
Intent intent = getIntent();
mUserId = intent.getStringExtra("userid");
mAuth = FirebaseAuth.getInstance();
mUser = mAuth.getCurrentUser(); // unused?
mDatabase = FirebaseDatabase.getInstance();
mUserRef = mDatabase.child("User").child(mUserId);
if(requestSinglePermission()){
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
mMapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mMapFragment.getMapAsync(this);
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mLocationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
checkLocation();
}
final MapsActivity2 self = this;
Button btnEnable = (Button) findViewById(R.id.enable_btn);
btnEnable.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// On click, saves last location to Firebase RTDB
long latitude = self.mLatLng.getLatitude();
long longitude = self.mLatLng.getLongitude();
String pushId = mUserRef.push().getKey();
Map<String, Object> childUpdates = new HashMap<>();
childUpdates.put("/Latitude/" + pushId, latitude);
childUpdates.put("/Longitude/" + pushId, longitude);
mUserRef.updateChildren(childUpdates)
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.w(TAG, "btnEnable#onClick:onFailure", databaseError.toException());
}
});
}
});
}
#Override
public void onLocationChanged(Location location) {
String msg = "Updated Location: " +
Double.toString(location.getLatitude()) + "," +
Double.toString(location.getLongitude());
Toast.makeText(this, msg+userId, Toast.LENGTH_SHORT).show();
this.mLatLng = new LatLng(location.getLatitude(), location.getLongitude());
this.mMapFragment.getMapAsync(this);
}
If you wanted to save the current location to the database on every update to the location, you would use:
#Override
public void onLocationChanged(Location location) {
long latitude = location.getLatitude();
long longitude = location.getLongitude();
String msg = "Updated Location: " +
Double.toString(latitude) + "," +
Double.toString(longitude);
Toast.makeText(this, msg+userId, Toast.LENGTH_SHORT).show();
this.mLatLng = new LatLng(latitude, longitude);
String pushId = mUserRef.push().getKey();
Map<String, Object> childUpdates = new HashMap<>();
childUpdates.put("/Latitude/" + pushId, latitude);
childUpdates.put("/Longitude/" + pushId, longitude);
mUserRef.updateChildren(childUpdates)
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.w(TAG, "onLocationChanged:onFailure", databaseError.toException());
}
});
this.mMapFragment.getMapAsync(this);
}

My onLocationChange method is not being called

I have downloaded an android map project. And now i want to do something like this and i have implemented all of this thing but i am getting that on Location Changed method is not being called in my project but in other this method is being called. I am saying this because dialog is not being dismissed, zooming, and icon is not working,
Is there is way to solve this? or can we do all of that thing in on Map Ready which i have done in on Location change.

this is the exact answer of my question.
In that case, you have to request location updates as described at developers.google.com/android/reference/com/google/android/g‌​ms/…. You should do this in your onCreate() method. Your current location listener is from the incorrect package for your use. Use the location listener from the Google API package –
They should all be from the com.google.android.gms package. Make sure you are uniform when using the API

In order to use the onLocationChanged(Location) callback, you need to register your location listener with the location manager. Something like:
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
Since you have implemented the locationListener interface, for you it will look something like:
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);

Can't get user location using Google Play Services API Android

I have been trying to work with Google Play Services in my android app to get the user location but the MapsActivity seems not to update the location. I have tried out three tutorials but none of them seems to solve the issue of getting the user's location.

I have also added location access to my AndroidManifest.xml
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
and added the following dependencies in build.gradle:
compile 'com.google.android.gms:play-services-location:10.2.0'
compile 'com.google.android.gms:play-services-maps:10.2.0'
I had changed the dependencies from:
compile 'com.google.android.gms:play-services:10.2.0'
but it didn't solve the issue. The MapsActivity sticks to the default LatLag(0,0). Any help will be appreciated.

how to set my google Map app to be show my current location as default? [duplicate]

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));

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
}
}
});
Reference: https://developer.android.com/training/location/retrieve-current.html

I think that better way now is:
Location currentLocation = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);

If you don't need to retrieve the user's location every time it changes (I have no idea why nearly every solution does that by using a location listener), it's just wasteful to do so. The asker was clearly interested in retrieving the location just once. Now FusedLocationApi is deprecated, so as a replacement for #Andrey's post, you can do:
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
String locationProvider = LocationManager.NETWORK_PROVIDER;
// I suppressed the missing-permission warning because this wouldn't be executed in my
// case without location services being enabled
#SuppressLint("MissingPermission") android.location.Location lastKnownLocation = locationManager.getLastKnownLocation(locationProvider);
double userLat = lastKnownLocation.getLatitude();
double userLong = lastKnownLocation.getLongitude();
This just puts together some scattered information in the docs, this being the most important source.

This Code in MapsActivity Class works for me :
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
LocationManager locationManager;
LocationListener locationListener;
public void centreMapOnLocation(Location location, String title){
LatLng userLocation = new LatLng(location.getLatitude(),location.getLongitude());
mMap.clear();
mMap.addMarker(new MarkerOptions().position(userLocation).title(title));
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(userLocation,12));
}

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0,locationListener);
Location lastKnownLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
centreMapOnLocation(lastKnownLocation,"Your Location");
}
}
}

Make sure these permission are written in Manifest file

Your current location might not be available immediately, after the map fragment is initialized.
After set
googleMap.setMyLocationEnabled(true);
you have to wait until you see the blue dot shown on your MapView. Then
Location myLocation = googleMap.getMyLocation();
myLocation won't be null.
I think you better use the LocationClient instead, and implement your own LocationListener.onLocationChanged(Location l)
Receiving Location Updates will show you how to get current location from LocationClient

Location locaton;
private GoogleMap mMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
mMap.setMyLocationEnabled(true);
mMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
#Override
public void onMyLocationChange(Location location) {
CameraUpdate center = CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(), location.getLongitude()));
CameraUpdate zoom = CameraUpdateFactory.zoomTo(11);
mMap.clear();
MarkerOptions mp = new MarkerOptions();
mp.position(new LatLng(location.getLatitude(), location.getLongitude()));
mp.title("my position");
mMap.addMarker(mp);
mMap.moveCamera(center);
mMap.animateCamera(zoom);
}
});}}

FusedLocationApi has been Deprecated (Why Google always deprecated everything!)
location: retrieve-current
Here is the way to get it now:
private lateinit var fusedLocationClient: FusedLocationProviderClient
override fun onCreate(savedInstanceState: Bundle?) {
// ...
fusedLocationClient = LocationServices.getFusedLocationProviderClient(this)
}

public void getMyLocation() {
// create class object
gps = new GPSTracker(HomeActivity.this);
// check if GPS enabled
if (gps.canGetLocation()) {
latitude = gps.getLatitude();
longitude = gps.getLongitude();
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(this, Locale.getDefault());
try {
addresses = geocoder.getFromLocation(latitude, longitude, 1);
postalCode = addresses.get(0).getPostalCode();
city = addresses.get(0).getLocality();
address = addresses.get(0).getAddressLine(0);
state = addresses.get(0).getAdminArea();
country = addresses.get(0).getCountryName();
knownName = addresses.get(0).getFeatureName();
Log.e("Location",postalCode+" "+city+" "+address+" "+state+" "+knownName);
} catch (IOException e) {
e.printStackTrace();
}
} else {
gps.showSettingsAlert();
}
}

All solution mentioned above using that code which are deprecated now!Here is the new solution
Add implementation 'com.google.android.gms:play-services-places:15.0.1' dependency in your gradle file
Add network permission in your manifest file:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Now use this code to get current location
FusedLocationProviderClient mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
mFusedLocationClient.getLastLocation().addOnSuccessListener(new OnSuccessListener<Location>() {
#Override
public void onSuccess(Location location) {
// GPS location can be null if GPS is switched off
currentLat = location.getLatitude();
currentLong = location.getLongitude();
Toast.makeText(HomeNavigationBarActivtiy.this, "lat " + location.getLatitude() + "\nlong " + location.getLongitude(), Toast.LENGTH_SHORT).show();
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
e.printStackTrace();
}
});

From Google Sample (CurrentPlaceDetailsOnMap) for kotlin by FusedLocationProviderClient in order to setOnMyLocationChangeListener is deprecated
at first add implementation 'com.google.android.libraries.places:places:2.4.0' to dependencies
next in your fragment add these variables
private lateinit var fusedLocationProviderClient: FusedLocationProviderClient
private var lastKnownLocation: Location? = null
next in onViewCreated add this
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(requireContext())
in onMapReady call this method
private fun getDeviceLocation() {
/*
* Get the best and most recent location of the device, which may be null in rare
* cases when a location is not available.
*/
try {
val locationResult = fusedLocationProviderClient.lastLocation
locationResult.addOnCompleteListener(context as Activity) { task ->
if (task.isSuccessful) {
// Set the map's camera position to the current location of the device.
lastKnownLocation = task.result
if (lastKnownLocation != null) {
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(
LatLng(lastKnownLocation!!.latitude,
lastKnownLocation!!.longitude), DEFAULT_ZOOM.toFloat()))
}
} else {
logD("Current location is null. Using defaults.")
logD("Exception: ${task.exception}")
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(LatLng(35.6892, 51.3890), 15.toFloat()))
mMap.uiSettings?.isMyLocationButtonEnabled = false
}
}
} catch (e: SecurityException) {
logD("Exception: ${e.message}")
}
}
if lastKnownLocation be null you should update it with this method:
fun requestLocation(context: Context) {
val mLocationRequest = LocationRequest.create()
mLocationRequest.interval = 60000
mLocationRequest.fastestInterval = 5000
mLocationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
val mLocationCallback: LocationCallback = object : LocationCallback() {
override fun onLocationResult(locationResult: LocationResult) {
for (location in locationResult.locations) {
if (location != null && lastKnownLocation == null) {
lastKnownLocation = location
}
}
}
}
LocationServices.getFusedLocationProviderClient(context)
.requestLocationUpdates(mLocationRequest, mLocationCallback, null)
}
if you want, you can turn on your location by this
mMap.isMyLocationEnabled = true
mMap.uiSettings.isMyLocationButtonEnabled = false

Add the permissions to the app manifest
Add one of the following permissions as a child of the element in your Android manifest. Either the coarse location permission:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp" >
...
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
...
</manifest>
Or the fine location permission:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp" >
...
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
...
</manifest>
The following code sample checks for permission using the Support library before enabling the My Location layer:
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
mMap.setMyLocationEnabled(true);
} else {
// Show rationale and request permission.
}
The following sample handles the result of the permission request by implementing the ActivityCompat.OnRequestPermissionsResultCallback from the Support library:
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if (requestCode == MY_LOCATION_REQUEST_CODE) {
if (permissions.length == 1 &&
permissions[0] == Manifest.permission.ACCESS_FINE_LOCATION &&
grantResults[0] == PackageManager.PERMISSION_GRANTED) {
mMap.setMyLocationEnabled(true);
} else {
// Permission was denied. Display an error message.
}
}
This example provides current location update using GPS provider. Entire Android app code is as follows,
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.widget.TextView;
import android.util.Log;
public class MainActivity extends Activity implements LocationListener{
protected LocationManager locationManager;
protected LocationListener locationListener;
protected Context context;
TextView txtLat;
String lat;
String provider;
protected String latitude,longitude;
protected boolean gps_enabled,network_enabled;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtLat = (TextView) findViewById(R.id.textview1);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
#Override
public void onLocationChanged(Location location) {
txtLat = (TextView) findViewById(R.id.textview1);
txtLat.setText("Latitude:" + location.getLatitude() + ", Longitude:" + location.getLongitude());
}
#Override
public void onProviderDisabled(String provider) {
Log.d("Latitude","disable");
}
#Override
public void onProviderEnabled(String provider) {
Log.d("Latitude","enable");
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d("Latitude","status");
}

Simple steps to get current location on google map:
1 - create map activity so in onMap ready method you create LocationManager and LocationListener
2 - in onMap ready also you check for android version and user permission ==> if there is a permission give location update OR ask the user for permission
3 - in the main class check for result of permission (onRequestPermissionsResult) ==> if the condition is true so give location update
4 - in (onLocationChanged) method we create LatLng variable and get the coordinates from location then from mMap we (addMarker and moveCamera) for that variable we've just created, this gives us location when the user moves so we still need to create new LatLng in onMap ready to have user's location when the App starts ==>inside condition if there is permission (lastKnownLocation).
NOTE:
1) Do Not forget to ask for permissions (Location and Internet) in Manifest
2) Do Not forget to have Map key from google APIs
3) We used (mMap.clear) to avoid repeating the marker each time we (run the app or update location)

Why not to use FusedLocationApi instead of OnMyLocationChangeListener? You need to initialize GoogleApiClient object and use LocationServices.FusedLocationApi.requestLocationUpdates() method to register location change listener. It is important to note, that don't forget to remove the registered listener and disconnect GoogleApiClient.
private LocationRequest mLocationRequest;
private GoogleApiClient mGoogleApiClient;
private LocationListener mLocationListener;
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);
}

public class MainActivity extends ActionBarActivity implements
ConnectionCallbacks, OnConnectionFailedListener {
...
#Override
public void onConnected(Bundle connectionHint) {
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(

How to show my current location in Google Map Android using google API client

I want to show my location on a map and zoom in on it. I want to use the GoolgeAPIClient. The map renders and the the pointer is created but the location so wrong. I feel that the onMapReady is executed first even before the onConnected method of the GoogleAPIClient is called. Please help this is my code.

For targeting api-23 and higher:
See the answer here.
For targeting api-22 and lower:
Here is the full Activity code that does what you need, a modified version of my other answer here. It registers a location listener when the Activity loads, then when each location changed event occurs, it will add a Marker and also animate the map to center on the current location.
The key here is to wait until the onMapReady() callback has occurred before you request location updates.
Here is the full Activity code:
public class MainActivity extends AppCompatActivity implements
OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;
LatLng latLng;
GoogleMap mGoogleMap;
SupportMapFragment mFragment;
Marker currLocationMarker;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap gMap) {
mGoogleMap = gMap;
mGoogleMap.setMyLocationEnabled(true);
buildGoogleApiClient();
mGoogleApiClient.connect();
}
protected synchronized void buildGoogleApiClient() {
Toast.makeText(this,"buildGoogleApiClient",Toast.LENGTH_SHORT).show();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
#Override
public void onConnected(Bundle bundle) {
Toast.makeText(this,"onConnected",Toast.LENGTH_SHORT).show();
Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
if (mLastLocation != null) {
//place marker at current position
//mGoogleMap.clear();
latLng = new LatLng(mLastLocation.getLatitude(), mLastLocation.getLongitude());
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title("Current Position");
markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA));
currLocationMarker = mGoogleMap.addMarker(markerOptions);
}
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(5000); //5 seconds
mLocationRequest.setFastestInterval(3000); //3 seconds
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
//mLocationRequest.setSmallestDisplacement(0.1F); //1/10 meter
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
}
#Override
public void onConnectionSuspended(int i) {
Toast.makeText(this,"onConnectionSuspended",Toast.LENGTH_SHORT).show();
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Toast.makeText(this,"onConnectionFailed",Toast.LENGTH_SHORT).show();
}
#Override
public void onLocationChanged(Location location) {
//place marker at current position
//mGoogleMap.clear();
if (currLocationMarker != null) {
currLocationMarker.remove();
}
latLng = new LatLng(location.getLatitude(), location.getLongitude());
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title("Current Position");
markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA));
currLocationMarker = mGoogleMap.addMarker(markerOptions);
Toast.makeText(this,"Location Changed",Toast.LENGTH_SHORT).show();
//zoom to current position:
mGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng,11));
//If you only need one location, unregister the listener
//LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
}
}

its very easy, you required only one method which is important in MapLiveLocation that is OnLocationChanged
