Answer 1

you need to do it like that by using data:text/html, as prefix for your script

Try that in your browser tab

data:text/html,

it will fire the javascript and alert , and as well you can print some in html from url

so i guess you need just to open the tab with the script

 String suffix = "data:text/html,"
 String script = ""
 String url = suffix + script
 myWebView.loadUrl(url);

It's browser behaviour in desktop and mobile

I haven't try it in WebView.loadUrl and actually still if it's done by WebView.loadUrl it will be a security hole
