Hello,

I have been developing an application in Android which includes animation and sort of 2D graphics ?

how is it possible in Android ?

this is no high level animation, you find the eyes, the teeth and put some color over it. done.
Shouldn't be a problem to change the texture on these places.

but how we can put animation.

can i get any resources for it. means sample code or app

Thats just OpenGL ES. You can find some tutorials here in the forum or on my blog (see my signature)
