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…?) and 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
