Armadillo is the fully featured audio player library Scribd uses to play and download all of its audiobooks and podcasts, which is now open source. It specializes in playing HLS or MP3 content that is broken down into chapters or tracks. It leverages Google’s Exoplayer library for its audio engine. Exoplayer wraps a variety of low level audio and video apis but has few opinions of its own for actually using audio in an Android app.
