- Use GPU finish time as well as actual deadline to determine jank rate. - Use dynamic interval to adjust for 60/90hz switching - Move frame metrics reporting into JankTracker to adjust the deadline communicated to the app when in stuffing scenario. - Adjust double-stuffing detection to be a bit more readable. Test: GraphicsStatsValidationTest.java Test: adb shell dumpsys gfxinfo Test: FrameMetricsListenerTest Test: Log output of FrameMetricsObserver Bug: 169858044 Change-Id: I3a6b8ed163e2cf9cf2b67667110340ebe35f98a1
