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);
}

Solution 1:

notification.sound = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notifysnd);
notification.defaults = Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE;

if defined DEFAULT_SOUND, then the default sound overrides any sound

Solution 2:

R.raw.kalimba is an integer resource ID; you want the name of the sound resource in that Uri. So try:

notification.sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE
        + "://" + getPackageName() + "/raw/kalimba");
