setting ringtone for a specific application only
<p>I want to be able to set a ringtone which is associated to a particular application only. If the message with a special prefix arrives, my application intercepts it and does whatever it has to do. 
On message arriving, i want to be able to tell the user that the 'special' message has arrived, through a ringtone( which exclusively plays upon that kind of msg).
anyone with a lead, please help.</p>
