Getting location via a web application being run in a WebView

Question

m.google.com somehow requests the current location when loaded in Android's browser.

I want to do the same thing from a web page being loaded into a WebView in my own application. Is the only way to go about this with WebView.addJavascriptInterface(), or is there already a javascript interface available for webapps to use?

Answer 1

It's done via HTML5.
