Android GcmPubSub无效_参数异常

我已经在我的应用程序中实现了GCM。但在某些版本之前，它停止接收来自gcm的消息。当我通过http post发送消息时，谷歌说“InvalidRegistration”

调查显示，问题出在subscribeTopics（）中，它在最新版本中引发了无效的_参数。代码是

RegistrationEntertService.java

private void subscribeTopics(String token) throws IOException {
    for (String topic : TOPICS) {
        GcmPubSub pubSub = GcmPubSub.getInstance(RegApp.getContext());
        try {
            Log.i("KK_Reg", "Token to pubsub " + token);
            pubSub.subscribe(token, "/topics/" + topic, null);
            Log.i("KK_Reg", "PubSub subscribed");
        } catch (java.io.IOException ex) {
            Log.e("KK_Reg", "Subscribe topics error");
            Log.e("KK_Reg", ex.toString());
        }
    }
}

工作版本和失败版本之间的差异如下所示：

当然，我无法想象更改会导致代码失败。请提供帮助。

无效的\u参数可能是由错误的令牌、错误的主题格式（主题中的空格）或使用旧的gcm.register方法获取令牌造成的。你能确认这些不是问题吗？是的，我能。问题出在

local\u-token

中，但我不明白为什么-在我消除了var之后，我想一切都很好。我不确定为什么要使用local\u-token和token，但在订阅之前似乎有什么东西在改变local\u-token或token。我要再次检查RegApp.setGcmToken是否没有更改令牌的值。它不应该，因为我假设

public static void setGcmToken（字符串令牌）{should\u send\u gcm=true；gcmToken=token；}

如果它在没有附加var的情况下工作，那么GCM也不是问题。我建议检查您传递的值。
