OnMapReadyCallback

public interfaceOnMapReadyCallback

Callback interface for when the map is ready to be used.

Once an instance of this interface is set on aMapFragmentor MapViewobject, the onMapReady(GoogleMap)method is triggered when the map is ready to be used and provides a non-null instance ofGoogleMap.

If Google Play services is not installed on the device, the user will be prompted to install it, and the onMapReady(GoogleMap)method will only be triggered when the user has installed it and returned to the app.

Public Method Summary

abstract void
onMapReady(GoogleMap googleMap)
Called when the map is ready to be used.

Public Methods

public abstract voidonMapReady(GoogleMap googleMap)

Called when the map is ready to be used.

Note that this does not guarantee that the map has undergone layout. Therefore, the map's size may not have been determined by the time the callback method is called. If you need to know the dimensions or call a method in the API that needs to know the dimensions, get the map'sViewand register an ViewTreeObserver.OnGlobalLayoutListeneras well.

Do not chain theOnMapReadyCallbackand OnGlobalLayoutListenerlisteners, but instead register and wait for both callbacks independently, since the callbacks can be fired in any order.

As an example, if you want to update the map's camera using aLatLngBounds without dimensions, you should wait until bothOnMapReadyCallbackand OnGlobalLayoutListenerhave completed. Otherwise there is a race condition that could trigger anIllegalStateException.

Parameters
googleMap A non-null instance of a GoogleMap associated with theMapFragment orMapView that defines the callback.
