Pure Tones in Android

Question

Is there any way to generate and play pure tones in Android? I know there isn't any MIDI support in Android at the moment so I was wondering if there were any third party libraries for doing it?

In my experience, MediaPlayer actually will play MIDI files. As for generating the tones, the only library I know of is a general MIDI library, which you can probably use to create MIDI files on-the-fly and hand off to MediaPlayer for playback.

This blog post shows how to use the AudioTrack api and has an example of pushing a basic sine wav to it.
