Wish the webview of b4i wish AddJavascriptInterface

In B4A there is a method "addJavascriptInterface" so that if I want to call an app Sub from the javascript inside the webview, I just call it from js via B4A.CallSub

the b4i has no method "addJavascriptInterface", Although it can be replaced by OverrideUrl, it is inconvenient to pass the parameters,

wish add method "addJavascriptInterface" in b4i ,thanks

There is no equivalent feature in iOS.
