Create Animation for Android 3.0 tablets

I was using [android.view.animation] to create animation for android 2.3. but on a large screen (as in tablets) the animations(Fade, Translate, Zoom, Rotate) are not smooth sometimes. i want to explore [android.animation] for this. I want some suggestions for creating those basic animations in Android tablets. I am giving 2 examples that i need to solve using [android.animation]. When i was using the view.animation, i had a lot of problems. i want to know how to control the time in the seekbar. i want to use it in the tablets. also, 2 or more 开发者_运维问答animations running in the same time. how to do it smoothly?
