Elegant solution - create your own Animated View which will follow life-cycle rules.

public class AnimatedImageView extends android.support.v7.widget.AppCompatImageView {
    public AnimatedImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
        setImageDrawable(ContextCompat.getDrawable(
                context, R.drawable.animated_icon));
    }

    @Override
    protected void onAttachedToWindow() {
        // 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.
        super.onAttachedToWindow();
        AnimationDrawable tapAnimation = (AnimationDrawable) getDrawable();
        tapAnimation.start();
    }
}

here is animated_icon.xml
