- Replace UI_STATE_OVERVIEW with UI_STATE_FULLSCREEN_TASK. Overview no longer needs it's own status bar treatment as it's handled by ScrimView already. So remove instances of UI_STATE_OVERVIEW and replace some with UI_STATE_FULLSCREEN_TASK if a TaskView is behind the status bar. - Add ScrimView to fallback recents activity. - Remove scrim from Background state, don't fade it in until the gesture ends to RECENTS. Test: watch scrim and status bar colors during the following - Swipe up to home (no scrim, status bar matches task at first but then wallpaper once task isn't overlapping status bar) - Swipe up to overview (no scrim until let go to overview, status bar matches task at first, then wallpaper after not overlapping, then scrim once it's 90% opacity) - Quick switch from home (scrim fades in, status bar matches once it reaches 90% opacity) - Quick switch from app (no scrim, status bar matches center task) - Repeat above for 3P launcher and 2 button mode Fixes: 185681676 Fixes: 185286870 Change-Id: I9e5c292cc734e714169b9cc8268e8dad4e868aca
