blackberry - 从browserfield黑莓保存图像

Question

BrowserFieldConfig myBrowserFieldConfig = new BrowserFieldConfig();
    protocolController = new ProtocolController(browserField)
    {
        public void handleNavigationRequest(final BrowserFieldRequest request) throws Exception
        {
            try
            {
                //save image from <a href="clickimage"><img src="http://mydomain.com/image.jpg></a>
            }
            catch (Throwable e)
            {

            }
        }
        public InputConnection handleResourceRequest(BrowserFieldRequest request) throws Exception {
            return super.handleResourceRequest(request);
        }
    };
    myBrowserFieldConfig.setProperty(BrowserFieldConfig.CONTROLLER, protocolController);
    myBrowserFieldConfig.setProperty(BrowserFieldConfig.NAVIGATION_MODE,BrowserFieldConfig.NAVIGATION_MODE_POINTER);
    myBrowserFieldConfig.setProperty(BrowserFieldConfig.CONNECTION_FACTORY, _factory);



    browserField = new BrowserField(myBrowserFieldConfig);

    URLlink = "http://mydomain.com";

    browserField.requestContent(URLlink);

我将 browserfield 用于从服务器打开 Web 应用程序的黑莓应用程序。我尝试将由网页的 href 链接触发的网络图像保存到 SDCard/blackberry 存储。这个怎么做？添加信息：当我添加 BrowserFieldConfig.CONTROLLER 时，我的 web 应用程序无法打开。如果我删除它，它工作得很好......
