Setup Layout

Instructions
From the Project File Navigation Panel, navigate to app -> res -> layout and open activity_{type}.xml
Note: The activity xml file name is based on the type selected when starting the project. ie - Basic, Empty, or Fullscreen Activity.
Using Code view, Add the MapView code below within the main Layout, and replace any existing TextViews or other Views.


	<com.mapbox.mapboxsdk.maps.MapView
		android:id="@+id/mapView"
		android:layout_width="match_parent"
		android:layout_height="match_parent" />
