Amazon SNS订阅正在等待移动终端的确认

Question

我创建了2个主题，然后订阅了Android设备的主题，所有主题均成功返回。

然后几天后，我打电话给GetSubscriptionAttributes。我发现订阅的PendingConfirmation之一为true（无法删除），而另一个为false。其他主题也发生了同样的情况。我不知道为什么订阅待定。我能做什么？

以下是错误的订阅属性：

{
    "Attributes" : {
        "RawMessageDelivery" : "false",
        "Endpoint" : "arn:aws:sns:us-west-2:owner:endpoint\/GCM\/12031_gcm_phone\/fack",

        "SubscriptionArn" : "arn:aws:sns:us-west-2:owner:12031_off-3-zh-CN:fack"
    },
   "ResponseMetadata" : {

    }
}
