title: How to display an overlay on my Android GoogleMap (V2) above road level ?
body: <p>I have my own offline map data in my app but only for a small region. Now I'd like to overlay this data onto my Google Map V2. This also already works. The only thing missing now is that <code>GoogleMaps</code> still overlays it's road names / city names above my tiles.</p>
  
  <p>Is it possible to display a google map V2 in Android with <code>MAP_TYPE_NORMAL</code> and overlay custom tiles above roads?</p>
  
  <pre><code>TileOverlay overlay = map.addTileOverlay(new
  TileOverlayOptions().tileProvider(provider).zIndex(2000));
  </code></pre>
  
  <p>The zIndex does't seem to help me here.</p>
