Delivery receipt requests not working for XMPP Android (aSmack)

Question

I'm using OpenFire with aSmack.

I can't seem to get DeliveryReceipts working.

I do the following when I create a connection:

//create connection
connection.login(username, password);
DeliveryReceiptManager.getInstanceFor(connection).enableAutoReceipts();
DeliveryReceiptManager.getInstanceFor(connection).addReceiptReceivedListener(new ReceiptReceivedListener()
{
        @Override
        public void onReceiptReceived(String arg0, String arg1, String arg2)
        {
            Log.v("app", arg0 + ", " + arg1 + ", " + arg2);
        }
});

I'm sending a message to another user using:

//send chat
Message msg = new Message(id, Message.Type.chat);
msg.setBody(chat);
DeliveryReceiptManager.addDeliveryReceiptRequest(msg);
connection.sendPacket(msg);

The above does not work although the message gets sent with the ReceiptRequest. The listener does not get fired at the sender's end although the receiver receives the message. (I confirmed it through debugging that a DeliveryReceiptRequest does indeed get attached to the message that is sent).

I've also tried manually sending back the Receipt by using the following in my PacketListener with (MessageTypeFilter(Message.Type.chat)):

Packet received = new Message();
received.addExtension(new DeliveryReceipt(packet.getPacketID()));
received.setTo(packet.getFrom());
getConnection().sendPacket(received);

Still, the client at the receiving end receives the message alright but the listener does not get fired in the sender's system. Anything I'm missing?

Add these lines before you set up your connection and Auto Receipts will work with ReceiptReceivedListener. Seems like the DeliveryReceipt extensions aren't registered by default.

ProviderManager.getInstance().addExtensionProvider(DeliveryReceipt.ELEMENT, DeliveryReceipt.NAMESPACE, new DeliveryReceipt.Provider());
ProviderManager.getInstance().addExtensionProvider(DeliveryReceiptRequest.ELEMENT, new DeliveryReceiptRequest().getNamespace(), new DeliveryReceiptRequest.Provider());
