From http://developer.android.com/guide/webapps/webview.html#EnablingJavaScript

For example, if you're developing a web application that's designed specifically for the WebView in your Android application, then you can define a custom user agent string with setUserAgentString(), then query the custom user agent in your web page to verify that the client requesting your web page is actually your Android application.
