title: Google MapsActivity: Tileoverlay set attribution
body: <p>Mapbox TileOverlays require attribution. How can I set this in java?</p>
  
  <p>Here is my code to change the tileOverlay to a custom one. The attribution I have to use is this link: <a href="http://www.openstreetmap.org/copyright" rel="nofollow noreferrer">http://www.openstreetmap.org/copyright</a></p>
  
  <pre><code>overlayString = "http://a.tile.openstreetmap.org/{z}/{x}/{y}.png";
  provider = new CustomUrlTileProvider(256, 256, overlayString);
  mSelectedTileOverlay = gMap.addTileOverlay(new TileOverlayOptions().tileProvider(provider).zIndex(-1));
  </code></pre>
