This is my realization, is wrong

public class CustomTiledMapServiceLayer extends TiledServiceLayer{

               private TileInfo _titlinfo;
private static final double c[] = {
  4891.96981024998D, 2445.98490512499D, 1222.99245256249D, 611.49622628138D, 305.748113140558D, 152.874056570411D, 76.4370282850732D, 38.2185141425366D, 19.1092570712683D, 9.55462853563415D,
  4.77731426794937D
};
private static final double d[] = {
  18489297.737236D, 9244648.868618D, 4622324.434309D, 2311162.217155D, 1155581.108577D, 577790.554289D, 288895.277144D, 144447.638572D, 72223.819286D, 36111.909643D,
  18055.954822D
};


              @Override

protected byte[] getTile(int level, int col, int row) throws Exception {
  String url  = "http://mt"+(col%4)+".google.cn/vt/lyrs=t@128,r@174000000&hl=zh-CN&gl=cn&src=app&x="+col+"&y="+row+"&z="+level+"&s=";
  return url.getBytes();
}
              @Override
              protected void initLayer() {
  try {
   setTileInfo(new com.esri.android.map.TiledServiceLayer.TileInfo(new Point(-20037508.342787D, 20037508.342787D), d, c, d.length, 96, 256, 256));
   Envelope envelope1 = (Envelope)GeometryEngine.project(getInitialExtent(), SpatialReference.create(102113), getDefaultSpatialReference());
   setInitialExtent(envelope1);
   Envelope envelope = (Envelope)GeometryEngine.project(getInitialExtent(), SpatialReference.create(102113), getDefaultSpatialReference());
   setInitialExtent(envelope);
   super.initLayer();
   return;
  }
  catch (Exception exception) {
  }
}
}





Activity:
                  CustomTiledMapServiceLayer tileLayer = new CustomTiledMapServiceLayer("http://192.168.30.48:8080                                                                /MapProxy/mapLayers/Google/PHYSICAL/");
                  map.addLayer(tileLayer);
