Vuforia does not have specific API to support animation of 3D models (e.g. walking characters and similar_; for this, you'll have to find your own way to implement it.

Hi

Thanks for the answer , but im not talking only about a new 3D model ..

Im asking about how can i add animation for this model (it's very simple using Unity ) but i want to use Eclipse + android    

for example a 3D person who has 3 animations (walk , run , jump ..)

Here are instructions for adding models for the Vuforia Android SDK - https://developer.vuforia.com/resources/dev-guide/replacing-teapot

You'll need to convert your models to OBJ and use the script linked in that article to generate a header file describing the model.
