UrbanAirship：在 namedUser 上设置标签时出错

Question

按照 UrbanAirship 文档中的说明，我需要在 Android 中的演示应用上使用这行代码将 TagGroup 添加到 namedUser

airship.getPushManager().getNamedUser().setId("123456");
airship.getPushManager().getNamedUser().editTagGroups().addTag("loyalty", "elite").apply();

但是，LogCat 显示此错误：

D/UrbanAirshipDemo - UALib﹕ Received a response for tag groups: Response: ResponseBody:  ResponseHeaders: {null=[HTTP/1.1 400 Bad Request], Connection=[close, Transfer-Encoding], Content-Type=[application/vnd.urbanairship+json; version=3], Date=[Wed, 24 Jun 2015 20:02:06 GMT], Transfer-Encoding=[chunked], X-Android-Received-Millis=[1435176126629], X-Android-Response-Source=[NETWORK 400], X-Android-Sent-Millis=[1435176126427]} ResponseMessage: Bad Request Status: 400
E/UrbanAirshipDemo - UALib﹕ Update tag groups failed with status: 400
E/UrbanAirshipDemo - UALib﹕ Both add & remove fields are present and the intersection of the tags in these fields is not empty.

他们的 API 有什么奇怪的地方吗？来自这里的说明：http://docs.urbanairship.com/platform/android.html#named-user-tag-groups

只是简单的实现，但他们的 API 返回 400。推送通知工作正常

我能够重现同样的问题。错误信息不正确，真正的问题是标签组还不存在。组只能通过 Go 创建。尝试创建以下群组 - http://docs.urbanairship.com/topic-guides/tag-groups-walkthrough.html#create-a-tag-group，然后重试。

错误消息将在未来的版本中修复。
