I presented this at Chicago Roboto on April 20, 2017.

Available as code, video, slides, YouTube, & Speaker Deck.

One of Android’s core requirements is that the UI runs on the main thread and IO in the background. Though concurrency is powerful, it’s also frustrating to deal with forking threads.

In this talk we’ll:

⏰ Learn how smartphone CPUs contradict your memory
⏰ Discuss how Android’s compilers disregard your orders
⏰ Sync up on Java’s concurrency APIs
⏰ See how to make sexy apps that aren’t racy
⏰ Determine if reactive programming is the future

This talk covers a sequence of concurrency topics. Attendees will be able to fix volatile programs and block threading bugs before they happen.
