我是android的新手，我正在开发一个android项目，其中发送通知是该项目的功能。当用户收到通知时，每个工作正常的通知已成功发送和接收它打开一个对话框。在对话框中，当用户接受它时，有两个选项接受或拒绝，它将确认发送给用户，但是在接收方设备而不是发送方设备上接收确认。我认为这是一个注册问题

您从GCM服务获得的确认仅告知您GCM服务已收到该消息，无论其是否已交付给应用程序。即使安装了应用程序的设备已关闭，您也可以获得它。
如果要在将消息发送到应用程序时收到确认，则必须在收到消息时从应用程序中调用服务器。您可以在邮件中包含一些唯一标识符，并将该标识符从您的应用程序发送到您的服务器以确认交付。
这是与确认相关的堆栈溢出票证：Client(android application) acks for sent gcm messages
