Android qbChatDialog.sendMessage（chatMessage）上的应用程序崩溃；

环境详细信息（操作系统、浏览器信息、SDK） 版本）Android，SDK:3.20

登录应用程序并与其他用户聊天时的预期行为 用户它工作正常，但一旦我退出应用程序并启动 再次，在聊天对话框应用程序崩溃时发送消息

实际行为应用 不应该崩溃

日志（请使用github gist）

复制行为的步骤 ->登录应用程序 ->在用户对话框中发送消息 ->从应用程序退出（也从后台终止） ->重新启动应用程序 ->转到“对话框列表”活动并选择“对话框” ->键入消息并单击发送按钮，应用程序将崩溃

还有其他意见吗？我还做了reloginToChat（用户），它提供了 成功回应。并在聊天助手中设置以下属性 阶级
