The heart of this change are two things: 1) Instead of using the force hide mechanism to hide windows behind Keyguard, we actually make the activities invisible in activity manager. 2) When Keyguard is going away, we change the visibilities in activity manager and run an app transition. At the very core we move the responsibility of hiding activities to ActivityStack, which checks whether Keyguard is showing, and then hides all non-show-when-locked activities. For that, we need to check whether any window of an activity has SHOW_WHEN_LOCKED set. We introduce a callback from WM -> AM in case these Keyguard flags have changed. Furthermore, we decide whether to occlude Keyguard in KeyguardController, which just checks whether the top activity has SHOW_WHEN_LOCKED set. When this state changes, we prepare an occlude/unocclude app transition, and in PWM we just inform the Keyguard about the animation so SysUI can play along this animations in a mostly synchronized manner. Since we now use an app transition when unlocking the phone, we get lockscreen launch animations for free - window manager automatically waits until the activity is drawn, or directly executes the transition if there is nothing to animate. Thus, we can remove all the infrastructure around "waitingForActivityDrawn". The logic to show/hide non-app windows is moved to policy, and we add the ability to run animations on non-app windows when executing an app transition.
