  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.init();
    // Set by <content src="index.html" /> in config.xml
    super.loadUrl(Config.getStartUrl());
    //super.loadUrl("file:///android_asset/www/index.html")
  }

Bugs

2nd scan with Moodstocks:
