However, note that it is only the animation passed into the initial - * {@link AnimatorSet#play(Animator)} method that is the dependency in any of the successive - * calls to the <code>Builder</code> object. For example, the following code starts both anim2 - * and anim3 when anim1 ends; there is no direct dependency relationship between anim2 and - * anim3: - * <pre> - * AnimatorSet s = new AnimatorSet(); - * s.play(anim1).before(anim2).before(anim3); - * </pre> - * If the desired result is to play anim1 then anim2 then anim3, this code expresses the - * relationship correctly:</p> - * <pre> - * AnimatorSet s = new AnimatorSet(); - * s.play(anim1).before(anim2); - * s.play(anim2).before(anim3); - * </pre> - * <p/> - * <p>Note that it is possible to express relationships that cannot be resolved and will not - * result in sensible results.

In general, circular dependencies like this one (or more indirect ones where a depends - * on b, which depends on c, which depends on a) should be avoided.
