I just pop up the text "Loading..."

I think I've seen this animated (... -> -> . -> .. -> ...), this is quite good. But the animation is important. Without it user can think that the app froze, especially in the world where every other app shows some sort of animation.

Unfortunately many apps get stuck in the “loading” state—the fact that the loader is animating does not mean it is not stuck!
