What are the settings to enable or disable in WebView to do this?
If you want to use a webview with exactly the same features as the native android browser, you have to check MANY options and settings. A WebView is made to NOT use all of the browsers options and settings for better performance and for having more controll on what the users can and can not do while browsing. to figure out all the opportunities you should read through the api documentation here: http://developer.android.com/reference/android/webkit/WebView.html
For some further dealing and handling with the WebView class also here are some usefull sample codelines: http://pankajchunchun.wordpress.com/2013/01/09/example-of-webview-with-result-handler-and-connection-timeout-handler/
I hope this will help you.
