Class Overview

A Map component in an app. This fragment is the simplest way to place a map in an application. It's a wrapper around a view of a map to automatically handle the necessary life cycle needs. Being a fragment, this component can be added to an activity's layout file simply with the XML below.

<fragment
    class="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
A GoogleMap can only be acquired using getMap() when the underlying maps system is loaded and the underlying view in the fragment exists. This class automatically initializes the maps system and the view; however you cannot be guaranteed when it will be ready because this depends on the availability of the Google Play services APK. If a GoogleMap is not available, getMap() will return null.

A view can be removed when the SupportMapFragment's onDestroyView() method is called and the useViewLifecycleInFragment(boolean) option is set. When this happens the SupportMapFragment is no longer valid until the view is recreated again later when SupportMapFragment's onCreateView(LayoutInflater, ViewGroup, Bundle) method is called.

Any objects obtained from the GoogleMap is associated with the view. It's important to not hold on to objects (e.g. Marker) beyond the view's life. Otherwise it will cause a memory leak as the view cannot be released.

To use this class, you must include the Android support library in your build path.
