Android 使用Google Cloud Messenger令牌订阅主题，收到无效参数

我遵循google提供的注册gcm令牌的示例：

我已经正确生成了google-services.json文件，并且能够接收推送令牌。但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);

它抛出无效的_参数异常：

这是我收到的推送令牌的一个示例：

我已经查看了有关订阅主题的文档，但没有说明我收到无效\u参数异常的原因：

似乎到目前为止还没有人能解决这个问题，所以我将给出我找到的解决方案

问题是我们有几个进程来注册GCM。因此，在60%的情况下，当我们在同一个应用程序中注册自己的设备后，另一个进程在GCM上向自己的发送者注册。因此，当我们尝试订阅主题时，gcm令牌无效，因为同一设备、同一应用程序已为另一个发送者注册了gcm

为了解决这个问题，我们所做的是从另一个进程获取发送者id，然后将其附加到发送者

假设我们的发送者id是“1234567”，他的发送者id是“7654321”，所以当我们在GCM上注册我们的应用程序时，我们使用“12345677654321”，而不是只解析“1234567”，由coma分隔

这允许我们获得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，它不会使自己的GCM令牌无效。（他的GCM令牌仍然有效，因为我们将其发送者包括在请求中）

来自迪拜的干杯

我认为问题在于在获取实例时使用

this

。更改InstanceID InstanceID=InstanceID.getInstance（此）to

InstanceID InstanceID=InstanceID.getInstance（getApplicationContext（））

和

GcmPubSub pubSub=GcmPubSub.getInstance（此）

to

GcmPubSub pubSub=GcmPubSub.getInstance（getApplicationContext（））以确保它们在相同的上下文中。您好：谢谢您的回复。我认为这不是问题所在。该代码在近40%的时间内有效。因此，在代码运行时应该有一些条件更改。RegistrationEntService从IntentService扩展而来，IntentService从Service扩展而来，后者从ContextWrapper扩展而来，ContextWrapper从上下文本身扩展而来。这不应该是问题，我明白了。您是否检查了您正在使用的令牌，或者您正在使用gcm.register（）获取令牌，这些可能是导致问题的原因。否。正如你所看到的，事实并非如此。我对这个答案很感兴趣，但是你如何“从另一个进程获取发送者id，然后将其附加到我们的发送者。”？我已经花了一段时间研究它。我不确定答案是否正确。发件人id是您在清单中拥有的。我想就加在那里吧。
