Hi!

I'd like to write an application which is able to send messages to the server (with the help of gtalk) and to receive them from server (via gtalk again).

I failed to make GTalkDataMessageSender (this is one of the demos provided) work. Each time I start it
message "the default Gtalk session cannot be found" appears.

Any ideas?

Have you set up XMPP settings?

Go to Dev Tools (in the emulator) then scroll to XMPP settings and enter a gmail account.

Thanks, it works now.

Is it possible to initiate data exchange between a server and an Android application via GTalk?

First, I'd like be able to send a message from Android app. to GTalk desktop client, but I cannot guess how to do it. For example, there is a method IGTalkSession.sendDataMessage(String to, Intent broadcastIntent) which should be used to send a message from one device to other (like in GTalkDataMessageSender, GTalkDataMessageReceiver demos).

How can it be used to send a message to the server? or may be there is another way to do it?

Hii

I went to the Dev Toolv.Add account in XMPP Settings .But not successed .The error message: wrong pass and username . But when i used that username and password sign in Google Talk .That work

Hi all,

I am using tatasu's code for creating a gtalk service(chat client).
Here two classes are used one is messaging.java and other is simpletalk.java.

In the methods of messaging.java we have many methods overridden.
But this methods are not overridded in the code i am getting.

The messaging.java is as below....can you plz tell me how can this be done....i have tried the overridding phenomenon(as how a method is overrided), but i am still facing the problem..

The lines creating problems are made red....

Hi swapsnil
Even i Faced the similar problem while using tatsu code

Instead of copying the complete project of tatsus code in the work space and importing the project

Create a New Project in the name of Simple Talk and copy the source and resourse in the newly created projecte by you...

u can over come the problem now

and i am unable to solve one problem in the Gtalk of u overcome it send me a reply

I am unable to get the result for the below query


managedQuery(Im.Messages.CONTENT_URI, null,
Im.Messages.CONTACT + "='" + mContactName + "'", Im.Messages.DATE + " ASC"), from, to)

swapsnil,

Thanks for your post. Your code,


and


was the answer I have been looking for in trying to resolve the rounding and display issues with displaying my numerical values in my list.

This is what I did...
