你好，请问使用那个版本 ChatKit？
能描述一下崩溃复现的流程步骤吗？
崩溃的原因不在于chatkit，是因为我们在会话界面添加了一个view，然后联网操作导致的，然后后重新再进入到leancloud的时候就会出现会话列表是空列表，提示错误 idList is empty，debug时候发现属性里面member值为空。chatkit我不知道是那个版本，我是去年八月份导入的lib包。

你好，我这边不清楚您具体的代码逻辑，具体功能需求等上下文，无法复现以及定位您说的问题。
您描述的这种场景，并不是 SDK 的问题导致的崩溃，LeanCloud 不提供技术支持。
另外补充一点，您上面的提供的日志信息并不是 crash 的打印日志，上面日志这个错误是是因为你还没有接入自己的用户体系。
ChatKit 用户体系相关可以参考文档：ChatKit 使用指南 · Android 。
好的 ，我再排查一下
我最近，仔细排查了一下这个问题，并不是因为我们程序崩溃导致的，而且我们也加了用户体系了。出现的情况是偶尔的 ，但是一般出现在两个场景：1.用户非正常退出。2.用户收到了消息通知，但是已经退出登录了，其后用户换手机登录，显示空会话，并且空会话会有未读消息角标，错误提示idList is empty。
另外，我们的会话列表是在本地缓存中获取的。
