Understanding and Implementing Audio on Android
summary
Concrete implementation notes and outcomes: compares MediaPlayer, SoundPool and ExoPlayer, inspects Android’s AudioService, and ships audio for a smart oven. Uses SoundPool for low-latency taps and MediaPlayer for larger files, implements audio focus and themes, and loads common sounds eagerly. Shows state-machine pitfalls, a slider UI that requires mixing simultaneous notes, a wake-sound race that produces static, and APK bloat from packed assets, so workarounds are practical but imperfect.
