In addition to deciding how your app content is organized for navigating and browsing (tasks 1 and 2), you need to decide whether you want any custom controls for playing the content.
Car makers take care of implementing and styling the playback view and the minimized control bar. They also provide a basic set of playback controls, including Play/Pause, Next, Previous, and Overflow. If these controls are sufficient for your app, then you’re done.
