问题
I need to load an HTML5 / Javascript game into a WebView.
Since this works on an old phone running Gingerbread but fails on a Nexus7 running KitKat, I'm guessing maybe it's something to do with the new Chromium based WebView in Android 4.4? The game works fine in the Chrome Browser on the Nexus7, but not in the WebView in my app.
Any advice where I should be looking to track down the source of this problem would be greatly appreciated.
The LogCat when I run on the Nexus7 is:

Here's how I'm currently implementing the WebView.
// webview
final WebView webView = (WebView)view.findViewById(R.id.game_webview);
webView.setWebChromeClient(new WebChromeClient());
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setDomStorageEnabled(true);
settings.setUseWideViewPort(true);
settings.setLoadWithOverviewMode(true);
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
});
webView.loadUrl("http://www.xxxxxxx.xxx.xx/xxxxx/xxx/index.html");
