This took me awhile to figure out and to get working, but once I did, the concept seemed so simple. 这花了我一段时间才能弄清楚并开始工作，但是一旦我做到了，这个概念似乎就这么简单。 Look into BrowserContentProvider. 查看BrowserContentProvider。 If my memory serves, you can find an example of this in the SDK. 如果需要我帮忙的话，您可以在SDK中找到一个示例。 Essentially, you can register a BrowserContentProvider with your application. 本质上，您可以在应用程序中注册BrowserContentProvider。 Then, you set up your website link with a certain extension. 然后，您设置具有特定扩展名的网站链接。 When the BlackBerry browser doesn't know how to handle that extension, it will go around and "ask" if any other applications know how to handle it. 当BlackBerry浏览器不知道如何处理该扩展名时，它将绕开并“询问”是否有其他应用程序知道如何处理该扩展名。 Your application can then recognize it and request the foreground (to open on top of the browser). 然后，您的应用程序可以识别它并请求前台（在浏览器顶部打开）。
