I normally would just test this out myself, but it seems that my version of B4A (9.01) does not work with the available widget example code.
I am hesitant to update B4A and deal with all the "gotchas" of doing such, only to find out what I can't use webview in a widget.
I might be willing to go through all that hassle if I know for sure I can use webview in a widget.
So, does anyone know if I can use a webview in a widget and have it "refresh" every minute or so?
