Previously, AnimatorSet incorrectly checked whether child animations were 'running' to figure out what to cancel. If a child animation was started, but sitting in a startDelay phase, it was not 'running', so the right cancel/end events would not propagate. The fix is to add a new isStarted() API to Animator, which returns true when the animator has started (but not yet ended), regardless of whether the animator has a startDelay or not. It's basically a superset of the existing isRunning() method, which only returns true when an animator has actually started setting values. Change-Id: I126814cb6637b58295b6d18d9b155235671f99be
