Android Question NB6 [SOLVED] - How do I stop the "custom sound playback" by clicking a button on my app?

Hi there

I have successfully implement the NB6 notification with custom sound. Thanks.

However Id like to stop/cancel the sound playback, when I click a button on my app. How can I do that?

Thanks
