Hi Alberto,
I just sent you the 10EUR donation, I like your lib a lot so far I just briefly tested and basic connection, getting roster, message sending works fine (tested with jwchat.org).
A list of things I didn't see yet but would love to have:

• account creation from the app (but you seem to say it depends on the server?)
• getting presence info for contacts in the roster
• sending binaries (mainly photos, smileys, stickers and such)
• search contacts in the server's directory

I used to work with Gloox, which is a C++ lib, but I don't know Smack that much.

Hi Alberto, I try your xmpp lib but when I try to log in, I get a NetworkOnMainThreadException, I add this persmissions to the manifest

AddPermission(android.permission.ACCESS_NETWORK_STATE)
AddPermission(android.permission.INTERNET)
AddPermission(android.permission.ACCESS_WIFI_STATE)

but I get the same result, I try it in android 4.0 and 4.4.2 , is a bug?, can you help me?, thanks in advance

[Leni Berry]

the library download page broken...

 

[Alberto Iglesias]

Hello Leni,

Sorry.. Go to www.visualnet.inf.br/store the library is available in my page.

 

[Reids]

Is it possible to add fetch offline message on server?
xabber has feature which if receiver message isoffline, it can call certain command to retrieve last message,
but when target online, last sended message is fetched something like this http://xmpp.org/extensions/xep-0013.html

 

[Alberto Iglesias]

I will take a look in a library and I think is possible....

Look this thread: http://stackoverflow.com/questions/7454995/getting-offline-messages-in-android-chat-application-with-use-of-asmack-library

 

[pappicio]

Hi all', I'm tring the lib, and I don't know if works on online server, but with my own openfire server it didn't, what wrong? It half/works, the only things I Can is login/logout from my device, but sensi or receive messages, It doesn't.

 

[Alberto Iglesias]

I tried with some online servers, some servers works, but others does not seem compatible...

[pappicio]

[Christian García S.]

Hello Alberto, very interesting the library, I have a project just for this, but I would like to know if you can also implement it for IOS?

Thank you

 

[Alberto Iglesias]

Yes, I can do that, but right now I don't have much time :-( But in a near future, I can do this for all users

 

[birnesoft]

Hello Alberto,

is it possible to recieve a message from any other, when I'm only logged in the Server?
I tried to communicate with an other chat program (pidgin). It recieved my message and all that was offline sended without createChat.
But with your Samples it's only possible to chat when both sites has open the Chat.
Is there any way to recieve a message without createChat?

best regards Björn
