Playing an arbitrary tone with Android

Question

Is there any way to make Android emit a sound of arbitrary frequency (meaning, I don\'t want to have pre-recorded sound files)?

I\'ve looked around and ToneGenerator

https://github.com/karlotoy/perfectTune

it's easy to use

add this to your dependencies

 compile 'com.github.karlotoy:perfectTune:1.0.2'

And you use it like this:

PerfectTune perfectTune = new PerfectTune();
perfectTune.setTuneFreq(desire_freq);
perfectTune.playTune();

to stop the tune:

perfectTune.stopTune();
