Use this class to initialize the Google Maps SDK for Android if features need to be used before obtaining a map. It must be called because some classes such as BitmapDescriptorFactory and CameraUpdateFactory need to be initialized.
Do not use this class if you obtain a valid GoogleMap reference using the onMapReady(GoogleMap map) callback. Instead provide the callback to either MapFragment#getMapAsync() or MapView#getMapAsync(). For examples, see the sample application.

Public Methods public static synchronized int initialize (Context context, MapsInitializer.Renderer preferredRenderer, OnMapsSdkInitializedCallback callback)Specifies which MapsInitializer.Renderer type you prefer to use to initialize the Google Maps SDK for Android, and provides a callback to receive the actual MapsInitializer.Renderer type. This call will initialize the Google Maps SDK for Android, so that its classes are ready for use. The callback will be triggered when the Maps SDK is initialized.
The Maps SDK only initializes once per Application lifecycle. Only the first call of this method or initialize(Context) takes effect. To make renderer preference meaningful, you must call this method before initialize(Context), and before MapFragment.onCreate(Bundle) and MapView.onCreate(Bundle). It's recommended to do this in Application.onCreate().
Do not use this method if you obtain a valid GoogleMap reference using the onMapReady(GoogleMap map) callback. Instead provide the callback to either MapFragment#getMapAsync() or MapView#getMapAsync(). This call will then have no effect other than triggering the callback for the initialized MapsInitializer.Renderer.
Note the following:
LEGACY to request the legacy renderer. No action is necessary if you prefer to use the latest renderer, as the latest render is the default.null. preferredRenderer Which MapsInitializer.Renderer type you prefer to use for your application. If null is provided, the default preference is taken. callback The callback that the Maps SDK triggers when it informs you about which renderer type was actually loaded. You can define what you want to do differently according to the maps renderer that is loaded. Returns
null. Returns
