Open Mobile Map Package

Shows how to open and display a map from a mobile map package.

How it works

To display a map from a MobileMapPackage:

  1. Create a MobileMapPackage specifying the path to the .mmpk file.
  2. Load the mobile map package with mmpk.loadAsync().
  3. After it successfully loads, get the map from the mmpk and add it to the map view: mapView.setMap(mmpk .getMaps().get(0)).
