I wanted to know if there is any way that I can call a JavaScript function from native Android Activity.

I came across:

webView.loadUrl(javascript:hello());

But it did not work for me.

Also, how will Android know in which html page does this JavaScript function reside?

Android can only call the javascript method if an html page is currently loaded in webView

webView.loadUrl(javascript:hello());

will call hello method writen in the html page only if the page containing this method is currently loaded in the webview control

first call

webview.loadUrl(Your html page url);

then call

webView.loadUrl(javascript:hello());
