Hi,
we decide to use more functionality from webview, because the main components are already working in html. So, i try to interact between webview and b4x.
I try the example which pulls a webview function from the activity. that works. But more important is the other way, pushing from the webview to the activity.
I found a article here that says the easiest way for b4a and b4i is the "OverrideUrl" from webview. I´ve tried it - it does nothing :/
Can anyone tell me what my mistake is?
In the html is a button
Webview1_OverrideUrl will not called...
Regards
