Changing default dialer tones
<p>I am creating an android app in which I am trying to modify the default dialer keyboard tones (1,2,3....) (NOT the incoming caller tunes etc) 
This is my first approach for such kind of android app. </p>

<p>Can anyone please guide me how to achieve this? 
I read it somewhere that "ToneGenerator" class can be used to achieve what I've in mind but not sure how to use this class. </p>

<p>A little help here will be highly appreciated.</p>

<p>Thnx..</p>
