The default Browser app for Android shows zoom controls when you're scrolling and also allows for pinch zooming. How can I enable this feature for my own Webview?

I've tried: 

webSettings.setBuiltInZoomControls(true);
webSettings.setSupportZoom(true);

but neither of the features get enabled as a result. Btw I've set a WebChromeClient and a WebViewClient for the Webview if that makes a difference.

Thanks!
