[yayaa]

Provides a simple abstract class that you can override only onLocationChanged and onLocationFailed.

new SimpleLocationListener() {
      @Override
      public void onLocationChanged(Location location) {
            // Code when location has changed
      }

      @Override
       public void onLocationFailed(@FailType int type) {
            // Code when location couldn't be retrieved
        }
};
