The May 2024 Meetup
22nd May 2024: https://www.meetup.com/the-aosp-and-aaos-meetup/events/299905713/
Introduction
Talk 1: Introducing AOSP Meetup Projects
Chris Simmonds
Talk 2: Automotive AOSP Ecosystem: challenges and opportunities for App Developers
In the last few years we’ve seen an increasing adoption from Automotive OEMs of Android based In-Vehicle Infotainment (IVI) platforms. While there are differences between platforms running with and without Google Automotive Services (GAS), the majority of apps can actually be built once and run anywhere, which is a paradigm shift for the industry. We’ll discuss the different categories of automotive apps and what is being done at COVESA to avoid ecosystem fragmentation.
José Freitas, Faurecia Aptoide
Talk 3: You Can’t Escape the Past: How early design decisions continue to influence Android today
Chet Haase talks about the team that built the Android operating system and why they chose to do certain things certain ways: the graphics stack, security model, the app programming language … these are things that affect us every day

Talk 2: What to expect in Android 15
While the source code for this year’s Android 15 ‘Vanilla Ice Cream’ release won’t be made public before early September (estimated), there’s a lot we can glean about this release from Google’s current developer previews, AOSP code changes, and documentation. Here’s a summary of what to expect

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
