我正在按照下面的 Google 推送通知教程进行操作。本教程使用 WAMP，但我已经让它与 SQL Server 一起使用。一切正常。我可以从服务器上的 php 文件生成一条消息，并将消息传递到注册的手机。

我遇到的问题是消息是应用程序升级 url 的 apk 的 URL。当手机收到消息时，消息在通知中，点击后消失。我想要发生的是当用户点击通知时，手机浏览器被打开。这将开始下载新应用程序。

如果消息是url，我怎样才能让android打开浏览器？

提前致谢，

尝试这样的事情，当您单击通知时，获取 url 并开始并打算使用 Intent.ACTION_VIEW 而不是活动：

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(yourUrlInString));
startActivity(browserIntent);
