Android: WebView Only Shows Blank Page

I'm trying to display a remote URL using WebView. I can display the URL on iOS, but on Android, all I see is a blank white screen, although the window title does have the correct title.

Why is Android showing only a blank white screen but it works on iOS? I'm using the 2.2 emulator; I can't use 2.3 because the evalJS function is horribly broken on the 2.3 emulator.

Here's a very simple app.js that demonstrates the problem:

Titanium.UI.setBackgroundColor('#000');
 
var window = Titanium.UI.createWindow({
    title: "Show Google",
    backgroundColor: "#000"
});
 
webView = Ti.UI.createWebView({
  height: Ti.Platform.displayCaps.platformHeight,
  width: Ti.Platform.displayCaps.platformWidth,
  top: 0,
  url: "http://www.google.com"
});
window.add(webView);
window.open();
