Android Question Quickblox Videochat: problem with the list of contacts

What is Quickblox?

There is a B4X project on Git???

Where is the example project showing the problem?

Quickblox is a website that provides some codes and tips for app coding.

Here is the source code I'm working on at the moment.

I've run it without any modifications first, and it gave me the initial problem I was talking about on my first message.
I've been trying to add modifications to the code relying on the documentation but nothing worked.
It the first time I am programming an app like this, so sorry if I am not clear enough in my explanations.

You need to write a wrapper for it with JAVA first to use it in B4A.
You need some java-knowledge to do that.
