Hello everyone,

I would like to know if there is an API to get information from my Joomla site to my android app. I've only found the extension JBackend which extend Joomla with an API and is compatible with K2.

Regards

I think JSON feeds would be the most easy solution.
Each part of K2 produces its own JSON feeds (?format=json) so you only have to parse these feeds in your app.

Thank you, that helps me a lot. In articles I get a JSON file, but how can I get the latest articles from my site? On the home page the json format unfortunately not works.

Regards

Create a menu item towards all categories.
You do not need to show this menu item anywhere but its feed will give you the latest items.

I've created a new menu item and published all categories on it. When I add the "?format=json" at the end of the url of the menu item, I get following error:

Fatal error: Call to undefined method JDocumentJSON::addCustomTag() in /www/htdocs/w00ec884/joomla/media/foundry/3.1/joomla/configuration.php on line 111

What is going wrong?

Thank you for your help.

The error you are getting is raised by an other extension. This is a bug of the extension which should check the document type ( HTML, XML or JSON ) before trying to add CSS and script tags to the head.

I disabled all extensions and found out, that there is a problem with Komento. Only if Komento is enabled I get this error. I will ask the support of the komento extension to help me.

Edit: An update to a newer version of Komento solved the problem.

Thank you for your great support.

You 're welcome
