As seen at the bottom of drawable animation example page:

It's important to note that the start() method called on the AnimationDrawable cannot be called during the onCreate() method of your Activity, because the AnimationDrawable is not yet fully attached to the window. If you want to play the animation immediately, without requiring interaction, then you might want to call it from the onWindowFocusChanged() method in your Activity, which will get called when Android brings your window into focus.

Hope it helps.. ;) Cheers

This is one of the best points given here. Not starting the animation during `OnCreate()`! — Levite, Dec 15 '14 at 09:53

try this

put your animation.xml file in anim folder

Simple Animation

Animation rAnim = AnimationUtils.loadAnimation(your_context, R.anim.animation);
animation.startAnimation(rAnim);

where animation is your imageview

update

Drawable Animation

    AnimationDrawable rocketAnimation;

    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);

      ImageView rocketImage = (ImageView) findViewById(R.id.rocket_image);
      rocketImage.setBackgroundResource(R.drawable.rocket_thrust);
      rocketAnimation = (AnimationDrawable) rocketImage.getBackground();
       final Thread thread = new Thread(new Runnable() 
    {
    @Override
    public void run() 
    { wait(1000);      
     activity.runOnUiThread(new Runnable() {@Override public void run()
    {
     rocketAnimation.start();
    }});
     }
});
thread.start();

    }

    public boolean onTouchEvent(MotionEvent event) {
      if (event.getAction() == MotionEvent.ACTION_DOWN) {
        rocketAnimation.start();
        return true;
      }
      return super.onTouchEvent(event);
    }

make folder anim in res and put your animation.xml in anim folder and than use this way

 Animation anim = AnimationUtils.loadAnimation(this,R.anim.animation);
 imageview.setAnimation(anim); 
 or
 imageview.startAnimation(anim);
