Chet and Romain, featuring a complete lack of Tor. In this episode, Chet and Romain talk about talking, speak about speaking, monologue monologuing. We have a conversation about various aspects of giving presentations. Everyone has their own style and techniques, and there are no right answers for giving talks that audiences enjoy. But we all have opinions and techniques that work for us; here are some of ours. We talk about making presentations more engaging, having co-speakers, picking topics, getting practice and experience, choosing events, and all kinds of other random stuff that came up in the conversation.

Chet, Dustin and Chris In this episode, we chat with Chris Craik and Dustin Lam from the AndroidX team about benchmarking. We cover the new AndroidX benchmarking library, how to use it, and what problems it solves. If you're wondering why Chet totally took over the interview towards the end, it's not that he wouldn't share the stage; Romain and Tor had to leave early and snuck out quietly.

Tor, Romain, Sumir, Ian, and Chet pose for a candid picture far from the recording studio, when they finally realized they'd forgotten to take a picture in the studio earlier. You'd think they'd have this process nailed by now, wouldn't you? I mean, 106 episodes; it's not like it's new and all. Honestly, what level of professionalism are we paying for here with this free service?

This is Part 2 of a much longer conversation that started in Episode 100, in which Chris talked about Android's UI hardware renderer.

In this episode, Chet and Tor Yigit Boyar talk with Chris Craik from the Android Toolkit team about graphics and the evolution of the UI renderer on Android. By the way, THIS IS EPISODE 100, PEOPLE! WE MADE IT! AND THEY HAVEN'T EVEN CANCELED US YET! Sure, it's because the people that could and would cancel us don't know we exist, but I still think it's an important milestone to still be here, still recording, still posting, and still talking about random Android development stuff. In the studio, we had a massive celebration for this amazing achievement, which consisted of recording the conversation and then returning to the office. (This is actually part 1 of a 2-part episode; we talked so much about rendering that we made the first part into its own episode.

Think of it as JobScheduler (in fact it uses JobScheduler internally when present), but handling situations and devices that don't have a recent enough version of the OS to have the JobScheduler API available.
