android animation on content of fragment
===

I need to have a frame by frame animation inside a fragment,

the animation works properly if i have it inside an activity, but inside my fragment it doesnt show,

    public class HomeTab extends Fragment {
         AnimationDrawable animation;
     	@Override
    	public View onCreateView(LayoutInflater inflater, ViewGroup container,
    			Bundle savedInstanceState) {
    		if (container == null) {
                 
                return null;
            }
    		
    		
    		animation = new AnimationDrawable();
            animation.addFrame(getResources().getDrawable(R.drawable.c_0), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c1), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c2), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c3), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c4), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c5), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c6), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c7), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c8), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c9), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c10), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c9), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c8), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c7), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c6), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c5), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c4), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c3), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c2), 100);
            animation.addFrame(getResources().getDrawable(R.drawable.c1), 100);
            
            animation.setOneShot(false);
                      		
    	}
    	
    	
    	/*class Starter implements Runnable {
    
            public void run() {
                animation.start();        
            }
            
        }
    
    	*/
  
  	
    }

so how to make this frame by frame animation work inside the fragment?

thanks!
