Complex animations in Android (transitions, backgrounds...)

I have in mind one simple application, but I would like to add some animations, transitions and so on. What technologies should I use besides Android SDK?

Concrete example: I have an activity with an animated background in constant loop (some waves, fancy shadows and graphics - maybe do it in Flash and import is or...?) a开发者_如何学Cnd I have a big TextView in front. When user taps on screen - text explodes or burns or something like that and new text reappear. If I click on some button it also provides some fancy animation.

Should I use AndEngine or...?

I would recommend you use libgdx: http://code.google.com/p/libgdx/

It has a bit of a learning curve, but its really flexibel
