MapsInitializer

public final class MapsInitializer extends Object

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.

If you are using MapFragment or MapView and have already obtained a (non-null) GoogleMap by calling getMapAsync() on either of these classes and waiting for the onMapReady(GoogleMap map) callback, then you do not need to worry about this class. See the sample application for some examples.

Nested Class Summary

enum MapsInitializer.Renderer Enables you to specify which MapsInitializer.Renderer you prefer to use for your application LATEST or LEGACY. 

Public Method Summary

synchronized static 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.
synchronized static int
initialize(Context context)
Initializes the Google Maps SDK for Android so that its classes are ready for use.

Inherited Method Summary

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. If you are using MapFragment or MapView and have already obtained a (non-null) GoogleMap by calling getMapAsync() on either of these classes, then this call will have no effect other than triggering the callback for the initialized MapsInitializer.Renderer. 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().

Note the following:

  • Use LATEST to request the new renderer. No action is necessary if you prefer to use the legacy renderer.
  • The latest renderer may not always be returned due to various reasons, including not enough memory, unsupported Android version, or routine downtime.
  • The new renderer will eventually become the default renderer through a progressive rollout. At that time, you will need to request LEGACY in order to continue using the legacy renderer. Check out Google Play Service release notes for rollout progress.
Parameters
context Required to fetch the necessary SDK resources and code. Must not be 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
  • A ConnectionResult error code.

public static synchronized int initialize (Context context)

Initializes the Google Maps SDK for Android so that its classes are ready for use. If you are using MapFragment or MapView and have already obtained a (non-null) GoogleMap by calling getMapAsync() on either of these classes, then it is not necessary to call this.

Parameters
context Required to fetch the necessary SDK resources and code. Must not be null.
Returns
  • A ConnectionResult error code.
