Hi Alberto!
I am trying to run your example program and am getting the following in the Log:

I have the libraries copied to the referenced libaries directory.

What have I missed?

Thanks for your help, if I can get this and the Android library working they will be very helpful!

 

[Alberto Iglesias]

Hey Lymey,

For me it´s working, look:

I suggest you create your own user and password in any jabber server to try, but you can try with my test user:

Check If .h .xml and .jar is in library folder and asmack-android-19-0.8.10.jar too


Server:jabber.chaotic.de
User: visualfriend
Pwd: MyJabber2015

 

[lymey]

Hi Alberto,
I haven't tried the basic For Android version yet - the problem I am having is with B4J

 

[Alberto Iglesias]

Yes, no problem too, look my screenshot: (I just take right now)

I recommend you update your JVM, I think is this the problem....

In the test I do now, I use the same user/password I do in the B4A example.....

 

[lymey]

Hi Alberto,
I am using jdk1.8.0_45\bin\javac.exe, I was using 1.7 before also.
I still get all the same warning messages, but I can at least have a chat using the example app and Pidgin, and Process One's One Team client.
is there a plan to send and receive files?
May thanks
Paul

 

[Alberto Iglesias]

I don't have plans to send/receive files in this protocol, maybe in the MQTT..

 

[lymey]

That would be a shame,
I think having send/receive file functionality would make this an even more useful (and commercial) library.
I would be happy to donate more if it had that capability!

Hi Alberto,
I was testing your test APP on a W10 PC and get these errors:

Any idea?

Hello tigrot,

I saw maybe something is missing like java dependencies in this machine. It´s not the problem with b4j library, I´m using in windows 10 too.

https://community.igniterealtime.org/thread/47774

Try to update java machines or upgrade to the last one.

And check the permissions when install this dependencies.


best regards,

Alberto Iglesias

Hello Alberto,
I have the same problem on a W10 PC, B4J 5.9, jdk1.8.0_66
Any idea?

I will try to reproduce with this version of JDK, because in my notebook is working fine. Maybe some dependecies from the smack component....
