使用 android Vidyo SDK 跟踪 `Vidyo` 会议参与者
Track `Vidyo` conference participants with android Vidyo SDK
我正在使用 Vidyo.io 服务将视频会议集成到我的 android 应用程序中。我已经能够使用 android-vidyo-sdk 附带的 VidyoConnector 示例应用程序成功实施视频会议。
但是，我想了解更多有关会议室和加入房间的参与者的信息。
我想象中的工作流程如下：
- 用户 1 想通过 android 设备进行 vidyo 电话会议。因此 User1 将使用 api 从我的后端服务器请求并获取一个新令牌。
- User1 将使用步骤 1 中获得的令牌和相应的 vidyo 会议室 resourceId 向其他参与者发送加入电话会议的邀请。
- 其他参与者将使用在步骤 2 中从 User1 获得的信息，并能够加入会议室。
到目前为止，我已参考 VidyoConnector 示例应用程序创建了一个名为 VideoChatActivity 的 activity，方法是对原始 VidyoConnector 示例应用程序的 MainActivity. VideoChatActivity 将通过 Intent 从我的应用程序中的另一个 activity 调用所有必要的信息来启动 vidyo 连接，如令牌、资源 ID、用户名等。跟踪每个的状态参与者 我已经实现了 VidyoConnector.IRegisterParticipantEventListener。请参考下面我的代码：

我想做的是为每次 vidyo 会议计时 session。为此，我需要区分创建房间的用户（在本例中为 User1）和后来加入房间的其他参与者。通过了解这一点，我可以根据 User1 的状态为 session 计时。当 User1 的 android 客户端收到对 VidyoConnector.IConnect 接口的 OnSuccess 方法的调用时（通过 VidyoConnector.Connect 启动到 vidyo 会议室的连接），我启动一个计时器并当 User1 的 android 客户端收到对 OnDisconnected 的调用时，我停止计时器以获取 session.
的总时间
现在的问题是我找不到区分创建房间的用户和后来加入房间的参与者的方法。现在每个人都被描绘成参与者。我注意到的另一件事是，只要会议室中有人，即使创建房间的用户离开，房间也会保持活动状态。
所以我的问题是：
有没有办法区分创建房间的 User 和后来加入房间的其他 Participants？
有没有办法在创建房间的用户退出时破坏房间并将所有参与者踢出房间？
我知道可以在我的后端服务器上跟踪所有这些信息，但我想知道是否可以在 android 客户端上这样做。
谢谢。
应该为每个用户生成令牌。所以你的工作流程应该如下 -
- 用户 1 想通过 android 设备进行 vidyo 电话会议。因此 User1 将使用 api.
从我的后端服务器请求并获取一个新令牌
- 用户 1 然后将向其他参与者发送邀请以加入电话会议，并使用 Connect 通话中使用的 "Resource Id"。
- 每个参与者都将获得自己的令牌，但会在 Connect 方法中使用 User1 共享的 "Resource Id"。
要区分用户和参与者，您必须在 android 应用中添加代码。当 user1 获得 "OnParticipantJoined" 时，它可以调用 "GetUserId" 来检查它是否匹配自己的 userId 或者它是否是不同的参与者。
关于踢出参与者，在当前版本的 Vidyo.io 中，无法将参与者踢出您的房间。在您的应用程序代码中实现这一点的一种方法是包装聊天方法。因此，如果 User1 离开自己的房间，它可以使用 "SendChatMessage" 向所有其他参与者发送 "Leave" 消息。在字符串中添加一些秘密前缀，例如 "xyz_Leave"，以便参与者端的应用程序代码知道不显示此消息而是对其执行操作。
我正在使用 Vidyo.io 服务将视频会议集成到我的 android 应用程序中。我已经能够使用 android-vidyo-sdk 附带的 VidyoConnector 示例应用程序成功实施视频会议。
但是，我想了解更多有关会议室和加入房间的参与者的信息。

我想做的是为每次 vidyo 会议计时 session。为此，我需要区分创建房间的用户（在本例中为 User1）和后来加入房间的其他参与者。通过了解这一点，我可以根据 User1 的状态为 session 计时。当 User1 的 android 客户端收到对 VidyoConnector.IConnect 接口的 OnSuccess 方法的调用时（通过 VidyoConnector.Connect 启动到 vidyo 会议室的连接），我启动一个计时器并当 User1 的 android 客户端收到对 OnDisconnected 的调用时，我停止计时器以获取 session.
现在的问题是我找不到区分创建房间的用户和后来加入房间的参与者的方法。现在每个人都被描绘成参与者。我注意到的另一件事是，只要会议室中有人，即使创建房间的用户离开，房间也会保持活动状态。 所以我的问题是：
有没有办法区分创建房间的
User和后来加入房间的其他Participants？有没有办法在创建房间的用户退出时破坏房间并将所有参与者踢出房间？
我知道可以在我的后端服务器上跟踪所有这些信息，但我想知道是否可以在 android 客户端上这样做。
谢谢。
应该为每个用户生成令牌。所以你的工作流程应该如下 -
- 用户 1 想通过 android 设备进行 vidyo 电话会议。因此 User1 将使用 api. 从我的后端服务器请求并获取一个新令牌
- 用户 1 然后将向其他参与者发送邀请以加入电话会议，并使用 Connect 通话中使用的 "Resource Id"。
- 每个参与者都将获得自己的令牌，但会在 Connect 方法中使用 User1 共享的 "Resource Id"。
要区分用户和参与者，您必须在 android 应用中添加代码。当 user1 获得 "OnParticipantJoined" 时，它可以调用 "GetUserId" 来检查它是否匹配自己的 userId 或者它是否是不同的参与者。 关于踢出参与者，在当前版本的 Vidyo.io 中，无法将参与者踢出您的房间。在您的应用程序代码中实现这一点的一种方法是包装聊天方法。因此，如果 User1 离开自己的房间，它可以使用 "SendChatMessage" 向所有其他参与者发送 "Leave" 消息。在字符串中添加一些秘密前缀，例如 "xyz_Leave"，以便参与者端的应用程序代码知道不显示此消息而是对其执行操作。
