Let's make some noise with Android
summary
A quick four‑step demo builds a tiny bird‑sound app that actually plays, showing concrete code for MediaPlayer vs ExoPlayer and when one is too heavyweight. The session lists SoundPool, MediaRecorder, AudioTrack/AudioRecord, MediaSession + MediaBrowserService for background control, and explains audio focus handling with transient/ducking examples. It dives into lower layers via OpenSL ES and SuperPowered, and notes MIDI support and noticeably improved latency since Marshmallow.
