我正在遵循Google提供的注册gcm token 的示例:
https://developers.google.com/cloud-messaging/android/start

我已经正确生成了google-services.json文件,并且能够接收推送 token 。但是,当我尝试使用以下代码订阅任何主题时:

    // Register the user to the global topic. This will help the device to be register on GCM
    GcmPubSub pubSub = GcmPubSub.getInstance(this);
    pubSub.subscribe(token, "/topics/global", null);

它将引发INVALID_ARGUMENT异常:
01-05 14:05:24.435 D/RegIntentService( 4330): java.io.IOException: INVALID_PARAMETERS

这是我收到的推送 token 的示例:

我已经查看了有关订阅主题的文档,但是没有任何内容说明为什么我收到INVALID_PARAMETER异常:

https://developers.google.com/android/reference/com/google/android/gms/gcm/GcmPubSub.html#subscribe(java.lang.String, java.lang.String, android.os.Bundle)

任何帮助表示赞赏。

最佳答案

到目前为止,似乎没有人能够解决此问题,因此,我将提供我找到的解决方案。

问题是我们有几个注册GCM的过程。因此,在60%的情况下,发生的情况是,在我们在同一应用中注册了自己的设备后,另一个进程便在GCM上使用自己的发送者进行了注册。因此,当我们尝试订阅主题时,gcm token 无效,因为同一设备,同一应用已为另一发送者注册了gcm。

为了解决该问题,我们要做的是从另一个进程获取发件人ID,然后将其附加到我们的发件人。

假设我们的发件人ID为“1234567”,而他的发件人ID为“7654321”,那么当我们在GCM上注册我们的应用程序时,我们将使用逗号分隔的“1234567,7654321”,而不是仅解析“1234567”。

这使我们可以获得对我们和另一个进程均有效的GCM token ,而如果另一个进程在我们之后注册了GCM,则它不会使自己的GCM token 无效。 (他的GCM token 仍然有效,因为我们将其发送者包括在请求中)。
