This is sample app that uses Google Maps Fragment with different map types, map styling and marker styling. It also tracks user location on map.
SupportMapFragment class is a subclass of the Fragment class. It is used to add map in an
application. It’s a wrapper around a view of a map to automatically handle the necessary life cycle
needs. You can include SupportMapFragment in a layout file using a <fragment> tag in
any ViewGroup, with an additional attribute:
android:name="com.google.android.gms.maps.SupportMapFragment"
Activity that instantiates SupportMapFragment calls getMapAsync() method to automatically
initialize the maps system and the view.
The activity that contains the SupportMapFragment must implement the OnMapReadyCallback
interface and that interface's onMapReady() method. The onMapReady() method is called when the
map is loaded.
