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,但我已经使用它与SQL Server一起工作。一切正常。我可以从服务器上的php文件生成一条消息,并将消息传递给已注册的手机。
我遇到的问题是消息是一个apk的URL,是应用程序的升级网址。当手机收到消息时,消息将显示在通知中,并在单击时消失。我想要发生的是当用户点击通知时,手机浏览器被打开。这将开始下载新的应用程序。
如果消息是网址,我如何让android打开浏览器?
提前致谢,

[编辑] 这是接收推送时执行的代码。它位于PushTestActivity类

答案 0 :(得分:1)
尝试这样的事情,当您点击通知时,获取网址并开始并打算使用Intent.ACTION_VIEW而不是活动:
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(yourUrlInString));
startActivity(browserIntent);
