After investigation, the widget Event content has

url -> https://fosdem-schedule-element-widget.hss.element.io/?theme=$theme&room=M.test`

but the URL should be

url -> https://fosdem-schedule-element-widget.hss.element.io/?theme=$theme&room=M.test&widgetId=$matrix_widget_id`

For this to work properly.

Hacking Element Android code with this value for the URL and it's still not working fine, I got a black screen as per opening directly the url https://fosdem-schedule-element-widget.hss.element.io/?theme=dark&room=M.test&widgetId=be36a59008cd909130504d809240d3fe187468399ff84db0e6923d5ab09a00ee&parentUrl=https://develop.element.io/ from a browser:

I have no more idea so far :/

Heads-up that officially only Element Web is supported for FOSDEM. It looks like there might be some room to make it work on Android too which would be awesome, but most of the efforts and the commitment went to Element Web for https://chat.fosdem.org

Fingers crossed, no guarantee 🤞

Note: The other widget of this room, "Livestream" has a correct url, and is working fine on Element Android 🎉

"url": "https://widgets-fosdem.ems.host/widgets/auditorium.html?widgetId=$matrix_widget_id&auditoriumId=$auditoriumId&theme=$theme"

Widget Event content	Element Android rendering
