The AOSP and AAOS Meetup
About
The AOSP and AAOS Meetup Group is a forum for talking about building, developing and testing products based on AOSP and AAOS (Android Automotive OS)
Community
Community is where we all come together to talk and exchange ideas. This meetup is part of that, and there is a Slack workspace (for historical reasons) where we can keep in touch between meetups: https://join.slack.com/t/theaospandaao-ij91284/shared_invite/zt-1k7lmay4j-fX1EGjNgN7OUh72jucQg2g
Devices
Android is not just smart phones. There is a separate section dedicated to Android running on devices of all types
Meetups
Meetings are held every two months, starting in March 2022 (so in 2023, that is January, March, May, July, September, and November). Each meeting is 2 hours, starting with 10 minutes meet and greet, followed by two or three talks of up to 20 minutes each on any topics that we find interesting, followed by time for networking. Since AOSP and AAOS developers are scattered over a wide area, this is an online meetup

Talk 2: Adventures with Systrace - measure and investigate the glass to glass latency in Android
What is the glass to glass latency in Android? This means how much delay is between the camera, taking a picture, and the screen, to display the picture again. This presentation is a technical tour through the Android graphics system and hardware. From the measurement setup, based on cables, LEDs, photodiodes and an oscilloscope, to camera sensors and the rolling shutter effect, to displays and refresh rates, to surfaceflinger and vsyncs, and last but not least to the ultimate tool to debug most of your performance issues, to Android’s systrace
