Haven't done much on this lately, as I've started work on a native Android app instead.
The current state of the Android app is that it has near real-time updates of messages, and shows avatars as well. It is also possible to send messages, if the user has setup account info in the preferences.
At the moment I'm working on getting view updates to be smoother and more efficient. There's still some work on that to be done before I can start on adding new features.
It is by default set to connect to my domain, but that can be changed in the preferences. If you want to try it on your own site, you will need to add the following script to the script directory of your UBB.threads installation:
Then change the app preferences to point to your domain: Base URL then needs to be set to the complete URL to the ubbthreads script, e.g. http://www.example.com/forum/ubbthreads.php Cookie Prefix needs to be set to the same as in your UBB.threads configuration.
