 Uri uri = Uri.parse( "geo:38.899533,-77.036476"  );
 Intent it =  new    Intent(Intent.ACTION_VIEW, uri);
 startActivity(it);
 //其他 geo URI 範例
 //geo:latitude,longitude
 //geo:latitude,longitude?z=zoom
 //geo:0,0?q=my+street+address
 //geo:0,0?q=business+near+city
 //google.streetview:cbll=lat,lng&cbp=1,yaw,,pitch,zoom&mz=mapZoom

 it.putExtra(Intent.EXTRA_TEXT,  "The email body text"  );
