How to set notification with custom sound in android

I copied the mp3 (kalimba.mp3) file into the `raw` folder in the `res` folder. But when the notification is triggered it produces the default sound. This is how I make a notification: ``` protected void GenerateNotify() { NotificationManager myNotificationManager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE); Notification notification=new Notification(android.R.drawable.ic_btn_speak_now,"hi",100); Intent intent=new Intent(getApplicationContext(),as.class); PendingIntent contentintent=PendingIntent.getBroadcast(getApplicationContext(),0, intent, 0); notification.setLatestEventInfo(getApplicationContext(), "Hi","date", contentintent); notification.flags |= Notification.FLAG_AUTO_CANCEL; notification.sound = Uri.parse("android.resource://com.example.serviceproject/" + R.raw.kalimba); myNotificationManager.notify(NOTIFICATION_ID,notification); } ```
