Over the years, Android has become one of the most widely used operating systems in the world. It can be found running on practically any hardware, from high-end flagship phones to smartwatches and IoT devices. Despite its massive popularity, the inner workings of Android are still a mystery to most. In this talk, Brad Hollander will look at the command line and investigate a running Android system to gain a better understanding of all the things Android does. This session will also cover what an app actually is, how it runs from the perspective of Android's Linux underpinnings, and what differentiates Android from a typical Linux distribution.
