Question

我按照谷歌提供的注册gcm令牌的示例： https://developers.google.com/cloud-messaging/android/start

我已经正确生成了google-services.json文件，我可以收到推送令牌。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);

抛出INVALID_ARGUMENT异常：

01-05 14:05:24.435 D/RegIntentService( 4330): java.io.IOException: INVALID_PARAMETERS

这是我收到的推送令牌的一个例子：

我已经检查了有关订阅主题的文档，但没有任何说明我收到INVALID_PARAMETER异常的原因：

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

感谢任何帮助。

Pd积。有完整的源代码来注册令牌：

        }

        try {

                    GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
            Log.i(TAG, "GCM Registration Token: " + token);

            // TODO: Send registration token to the server
            if (mResultReceiver != null) {
                Bundle bundle = new Bundle();
                bundle.putString(BUNDLE_KEY_GCM_TOKEN, token);
                mResultReceiver.send(0, bundle);
            }

            // 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);
            Logger.v(TAG, "User correctly register to the global token");

        } catch (Exception e) {
            Log.d(TAG, "Faield to complete token refresh", e);
        }
    }
}

Answer 1

到目前为止，似乎没有人解决这个问题，所以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。那么在60％的情况下发生的事情是，在我们注册我们自己的设备之后，在同一个应用程序中，另一个进程在GCM上注册并拥有自己的发送者。因此，当我们尝试订阅主题时，gcm令牌无效，因为相同的设备，同一个应用程序已为另一个发件人注册gcm。

要解决此问题，我们所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。

我们说我们的发件人ID是＆＃34; 1234567＆＃34;，他的发件人ID是＆＃34; 7654321＆＃34;，所以当我们在GCM上注册我们的应用时，而不是只解析＆＃34; 1234567＆＃34;，我们使用＆＃34; 1234567,7654321＆＃34;，以逗号分隔。

这允许我们获取对我们和另一个进程都有效的GCM令牌，而如果另一个进程在我们之后注册GCM，则它不会使自己的GCM令牌无效。（他的GCM令牌仍然有效，因为我们将其发件人包含在请求中）。
