Issue
I developed a mobile HTML5 game which works fine when I load the URL from the web. But when I display the index.html which calls the JavaScript from the assets folder on Android 4.0 it does not work. I have included logcat and code below.
public class BlockyBlaine extends Activity {
WebView webview;
AdView adView;
private class BlaineViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
adView = (AdView) findViewById(R.id.adView);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setPluginsEnabled(true);
webview.getSettings().setSupportZoom(false);
webview.setVerticalScrollBarEnabled(false);
webview.setHorizontalScrollBarEnabled(false);
webview.getSettings().setUseWideViewPort(false);
webview.getSettings().setDomStorageEnabled(true);
webview.loadUrl("file:///android_asset/www/index.html");
webview.setWebViewClient(new BlaineViewClient());
webview.setFocusableInTouchMode(false);
adView.loadAd(new AdRequest());
}
}

Solution
This is just a shot in the dark here, but it looks like your emulator requires you to call,
AdRequest adRequest = new AdRequest();
adRequest.addTestDevice(AdRequest.TEST_EMULATOR);
before calling,
adView.loadAd(adRequest);
Edit:
Read this and this. It looks like the Android team came to the decision that "file:///scheme" is insecure (beginning with 4.0).
Perhaps you could just upload the asset to dropbox (or somewhere online) instead and download the file at runtime.
