Android的GCM不起作用 [英] android GCM doesn't work

问题描述

我使用由古尔提供的例子，我建立了一个客户端应用程序接收通知和服务器端，这两个应用程序（code）为那些由谷歌提供。

I use the example provided by goole and I built an client side application to get notifications and a server side, both applications (code) is those provided by google.

我运行在客户端的应用程序，我得到的registration_id。一些巨大的字符串，这种格式是如下：

I run the application on the client side and I get the registration_id. some huge string, in this format which is below:

<$c$c>APA91bEgguwt98xLbivrXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXLxDalNoEktCSVbOkT0-uFH2FaRnfpkRME2tzuvr0BycMNEhX_Ix1PV_XXXXXXXXXXXXXXXXXXXXXN5hcseY_wA.

这证明我的客户端应用程序的工作原理。现在，服务器（Java，谷歌为例）：

This proves me that the client application works. Now the server (java, google example):

public static void main(String[] args) {

        Sender sender = new Sender("AIzaSXXXXXXXXXX_XXXXXXXXXXXXXXXrQOnoGZw");      
        Message message = new Message.Builder()
        .collapseKey("1")
        .timeToLive(3)
        .delayWhileIdle(true)
        .addData("message",
          "this text will be seen in notification bar!!")
        .build();

        try {
            Result result = sender.send(message, "APA91bEgguwt98xLbivrXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXLxDalNoEktCSVbOkT0-uFH2FaRnfpkRME2tzuvr0BycMNEhX_Ix1PV_XXXXXXXXXXXXXXXXXXXXXN5hcseY_wA", 3);
            System.out.println(result.toString());
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
}

这是服务器。当我运行的服务器我得到的结果是这样的： [邮件ID = 0：1341907115903155％921c249a00000031] 但在客户端上没有消息，我不明白为什么。什么是我从服务器上得到的回应是什么意思？它是成功的回应？

This is the server. When I run the server I got as result something like this: [ messageId=0:1341907115903155%921c249a00000031 ] but no message on the client and I don't understand why. What is the meaning of the response I got from server? Is it the success response?

我需要帮助来理解什么是错的？

I need help to understand what is wrong?

推荐答案

根据该的 GCM文档：

在第三方服务器上发布消息到GCM和接收消息ID后面，但这并不意味着该邮件已经发送到设备。相反，它意味着它被接受交付。会发生什么事被接受后，该消息取决于许多因素。

When a 3rd-party server posts a message to GCM and receives a message ID back, it does not mean that the message was already delivered to the device. Rather, it means that it was accepted for delivery. What happens to the message after it is accepted depends on many factors.

在最好的情况下，如果该装置被连接到GCM，屏幕上，并且没有节流限制（见节流），该消息将被立即递送

In the best-case scenario, if the device is connected to GCM, the screen is on, and there are no throttling restrictions (see Throttling), the message will be delivered right away.
