How can I make use of XMPP XEP-0184 “Message Deliv

Question

Hi is there any way to do android xmpp client which will be able to get message receive confirmation (XEP-0184) I read that there is XEP-0184 in smack but normal smack is not working with android(or I can't do it) there is always SASL authentication exception.

Answer 1

Smack received support for XEP-0184 with SMACK-331. You can't use Smack < 4.1 directly under Android, you need Smack 4.1 (or higher).

You can read more about Smack's XEP-0184 API in the javadoc of DeliveryReceiptManager.

Answer 2

Yes this works with normal Smack.

Gradle Dependencies

compile "org.igniterealtime.smack:smack-android:4.1.0"
compile "org.igniterealtime.smack:smack-tcp:4.1.0"
compile "org.igniterealtime.smack:smack-extensions:4.1.0" // <-- XEP-0184 classes

Prepare the XMPPTCPConnection i.e. before you connect() wire up a handler for when you get a delivery receipt

DeliveryReceiptManager.getInstanceFor(mConnection).addReceiptReceivedListener(new ReceiptReceivedListener() {
        @Override
        public void onReceiptReceived(String fromJid, String toJid, String deliveryReceiptId, Stanza stanza) {
            Log.d(TAG, "onReceiptReceived: from: " + fromJid + " to: " + toJid + " deliveryReceiptId: " + deliveryReceiptId + " stanza: " + stanza);
        }
    }); 

When sending a message, ensure you include a MessageReceiptRequest

Chat chat;
if (StringUtils.isNullOrEmpty(threadId)) {
    chat = getChatManager().createChat(to);
    Log.d(TAG, "sendMessage: no thread id so created Chat with id: " + chat.getThreadID());
} else {
    chat = getChatManager().getThreadChat(threadId);
    Log.d(TAG, "sendMessage: thread id was used to continue this chat");
}
Message message = new Message(to);
message.addBody("EN", messageText);
String deliveryReceiptId = DeliveryReceiptRequest.addTo(message);
chat.sendMessage(message);
Log.d(TAG, "sendMessage: deliveryReceiptId for this message is: " + deliveryReceiptId);

All done

Now, you can tell when a sent message has been received by the other side because the deliveryReceiptId obtained in the Chat.sendMessage(Message) code above will be logged by the onReceiptReceived callback set up earlier.
