This example show user-agent of your WebView, and also include a link to HTML5TEST to test your HTML compatibility. It's how it run on Nexus 7 running Android 4.4.2 KitKat, and on HTC One X running 4.2.2.
Run on Nexus 7, Android 4.4.2
Run on HTC One X, Android 4.2.2
Android 4.4 (KitKat) includes a new WebView component based on the Chromium open source project. The new WebView includes an updated version of the V8 JavaScript engine and support for modern web standards that were missing in the old WebView. It also shares the same rendering engine as Chrome for Android, so rendering should be much more consistent between the WebView and Chrome.
The new WebView adds Chrome/_version_ to the user-agent string.

You can simplier:
TextView textView = (TextView)findViewById(R.id.textView);
WebView webView = (WebView)findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
textView.setText(webSettings.getUserAgentString());
