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
must be acquired using getMapAsync(OnMapReadyCallback)
. This class
automatically initializes the maps system and the view.
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happens the SupportMapFragment is no longer valid until the view is recreated again later when
the SupportMapFragment's onCreateView(LayoutInflater, ViewGroup, Bundle)
method is
called.
Any objects obtained from the GoogleMap
are 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.
