title: Indoor map for a private building
body: <p>I am trying to create an application to show an indoor map of a building, and open the dialog box when anyone clicks on any part of that building. It's similar to IndoorGoogle Maps 6.0 for Android, but Indoor maps are currently available in selected locations in the U.S. and Japan only.</p>
  <p>I don't know whether I should use a WebView (because it has scrolling and zoom features) or an ImageView. How to show a marker in the image of the map like Google Maps? How should I save the direction from one part to another part of the building?</p>
