The Open Existing Map app demonstrates how to open an existing map as a PortalItem from a Portal. The app opens with a web map from a portal displayed. You tap on the navigation drawer icon to see a list of pre-defined web maps. Select any of the web maps to close the drawer and open it up in the MapView.

Portal objects represent information from a portal such as ArcGIS Online. PortalItem represents an item stored in a portal. We create a Map from a Portal & PortalItem objects then pass the Map to the MapView.
// get the portal url for ArcGIS Online
mPortal = new Portal(getResources().getString(R.string.portal_url));
// get the pre-defined portal id and portal url
mPortalItem = new PortalItem(mPortal, getResources().getString(R.string.webmap_houses_with_mortgages_id));
// create a map from a PortalItem
mMap = new Map(mPortalItem);
// set the map to be displayed in this view
mMapView.setMap(mMap);
