我很难通过 c2dm 接收消息。实际上，我偶尔会收到来自我们服务器的消息，但实际上只是数据的一半。（我期待一个 4 位数字，但只收到前 2 位数字.. oO"）。但是最近我们的广播接收器保持绝对沉默。因此我开始试验并将我自己的 c2dm 消息推送到谷歌服务器，看看情况如何是做。

在帖子的底部，您可以找到我如何发送和接收 c2dm 消息的示例类。这一切几乎都是独立的，因此您可以将其插入一些活动并拍摄C2dmStaticTest.autopilot( yourSenderId, "foo bar", yourServerSideAuthCode, this, this.getPackageName());

让我概述正在发生的事情：

  • 设置要在 BroadcastReceiver 中使用的静态变量
  • 注册广播接收器并设置动作和类别，androidManifest.xml否则它将如何。
  • 向 c2dm 服务器发送注册意图。

注意：本地内置广播接收器将为每个接收到的意图生成一条日志消息！每次在类中发出日志消息时，标签都会是“c2dmTest”。

当收到带有 registration_id 的 c2dm 答案时，这也会被记录下来，然后会推送一条 c2dm 消息。
我在这里尽可能地模拟我们的服务器以获得更多控制权。作为回测，我还发出了一条模拟实际 Intent 的 fakeC2DM 消息，并测试广播接收器在 RECEIVE 操作上的功能。

虽然我可以从 c2dm 服务器接收注册令牌，但我没有收到我推送到服务器的任何消息。正如介绍中提到的，当我们的 Web 服务器发送消息时，我观察到相同的行为。

我尽了最大努力，我相信我已经相应地实现了广播接收器，并且由于消息发送的服务器响应代码始终为 200/OK，我也相信消息已成功传递到服务器。

然而结果不是预期的，但我真的缺乏任何想法我还能做什么。寻找诸如“无法保证消息传递”之类的段落也不令人鼓舞。我的意思是现在根本没有交付任何东西：C

好的，将其呈现给我们的服务器人员，我了解到这status code: 200仅表明通信成功，而不是数据可能存在语义错误。

在这种情况下，我实际上还收到了一个 JSONObject 说明键不匹配的错误。
这就是我所说的各级沟通问题...
