This project is no longer maintained. As of Version 2.4, ExoPlayer supports custom playback speed.

And it is not such a awful state machine as the Android MediaPlayer.

This player is a MediaPlayer abstraction for Android. It mimics but simplifies the Android MediaPlayer through the usage of Kotlin.
As kotlin produces JVM bytecode this can be used from java too.

It also supports setting a custom playback speed for Android API >= 16 by using a custom implementation based on Prestissimo with heavy modifications.

This library is still in beta phase and its API is a subject to changes.

The player is defined through a simple interface called MediaPlayer which works like the Android MediaPlayer. There is one little difference: Instead of setDataSource(String) and prepare() it simplifies that by skipping that state so you call prepare(Uri) directly.

val player: MediaPlayer = SpeedPlayer(context) // or AndroidPlayer(context) if < API 16 or >= 23
val file = File("/storage/sdcard/test.mp3")
player.prepare(Uri.fromFile(file))
player.start()

For events you can simply set your listeners:

player.onCompletion { Log.i("Player", "Player completed") }
player.onError { Log.i("Player", "There was an error") }
player.onPrepared { Log.i("Player", "Player prepared!") }
