onConnected() method that belongs to the GoogleApiClient.ConnectionCallbacks interface gets invoked when connections to all the APIs are established. GoogleApiClient.ConnectionCallbacks and GoogleApiClient.OnConnectionFailedListener are implemented for addConnectionCallbacks and addOnConnectionFailedListener.
addOnConnectionFailedListener(this).build() GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(this) GoogleAPIClient allows us to call multiple Google APIs using a single call.įollowing is an example snippet to invoke the GoogleAPIClient with two APIs : Location Services and Drive API. To use Google Play’s Location Services API we need to call GoogleAPIClient first. The method onLocationChanged is invoked if the LocationListener has been registered with the location client using the requestLocationUpdates(GoogleApiClient, LocationRequest, LocationListener) or requestLocationUpdates(GoogleApiClient, LocationRequest, LocationListener, Looper) methods. .location.LocationListener : The LocationListener interface is used for receiving notifications from the FusedLocationProviderApi when the location has changed.
The methods must be used in conjunction with a GoogleApiClient client which we’ll look into shortly.

Need for introducing Google Play Location Services So why was there a need for introducing Google Play Location Services? Why hasn’t Google enhanced Android’s Location API?
