You need to put the data you need into the PendingIntent that will be broadcast when the delivery completes (or fails). When doing this you need to make sure that you create a unique PendingIntent for each message (you can do this by setting a unique ACTION on the Intent). Here's an example.

Instead of this:

    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
            new Intent(DELIVERED), 0);

Do this:

    long messageID = ... // This is the message ID, ie: the row ID in the SQLite database that uniquely identifies this message
    Intent deliveredIntent = new Intent(DELIVERED + messageID); // Use unique action string
    deliveredIntent.putExtra("messageID", messageID); // Add message ID as extra
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
           deliveredIntent, PendingIntent.FLAG_ONE_SHOT);

When you register the receiver, be sure to use the correct IntentFilter:

    registerReceiver(new BroadcastReceiver(){
        ...
    }, new IntentFilter(DELIVERED + messageID));

Now, when the delivery Intent is broadcast, you can get the data from it in onReceive() like this:

    public void onReceive(Context arg0, Intent arg1) {
        long messageID = arg1.getLongExtra("messageID", -1L);
        if (messageID != -1L) {
            // This is the message ID (row ID) of the message that was delivered
            ... do your processing here
        }
