2d mixed with activity, is that easy in android?
<p>My whole application is very common except an area that display 2d graphics(text marqueezing and some visual effect). The app is like a media player --- it has buttons, and lots of dialogs(for configuration uses). </p>

<p>I wonder how could I do this? </p>

<p>First I use activity and build-in animations but obviously the animations are too limited.</p>

<p>So should I use game engine to achieve good graphics? But how about those dialogs in this case? Are they hard to implement in game engine? Or I can mix activity dialog with 2d game engine?</p>
