Present time is available to apps, but is not currently stored inside FrameInfo. In this CL, we add a location for storing the present time inside FrameInfo. Currently, the metrics reporter is triggered after the buffer is sent to SurfaceFlinger. That means, metrics for anything that happens after gpu draw completes are currently not available. In a future CL, we will populate the 'presentTime' field. In a future CL, we will register a metrics observer inside ViewRootImpl in order to send this data to InputDispatcher. This will enable end-to-end touch latency metrics collection. Bug: 169866723 Test: printed present time inside FrameTimeline.cpp (surfaceflinger side) and compared to the values printed inside a metrics observer registered in ViewRootImpl (not done in this CL) Test: atest ViewFrameInfoTest Change-Id: I7d0f8c5d7b5a2572abdc4e107123e8938a36f582
