Can some explain / try how can I connect an Android Widget or a Windows Live Tile to my application so when it changes the data source the Widget and Tile get the data from that new source?
Since I cannot build them with Qt I need to connect them somehow.
I'm thinking of putting web url into an sqlite table and retrieve it from Widget(but can I access it from Widget?), that or make a file on the filesystem and based on what it's stored in it use to select proper data source. (same solutions for live tile).

Opened to suggestions.
