About the project

Agora e-Education is a sample project provided by Agora for developers in the education industry, which demonstrates how to use Agora Edu Cloud Service, Agora RTC SDK, Agora RTM SDK, Agora Cloud Recording, and the third-party Netless whiteboard SDK to quickly implement basic online interactive tutoring scenarios.

Applicable scenarios

Agora e-Education supports the following scenarios:

• One-to-one Classroom: An online teacher gives an exclusive lesson to only one student, and both can interact in real time.
• Small Classroom: A teacher gives an online lesson to multiple students, and both the teacher and students can interact with each other in real time. The number of students in a small classroom should not exceed 16.
• Lecture Hall: Thousands of students watch an online lecture together. Students can "raise their hands" to interact with the teacher, and their responses are viewed by all the other students at the same time.

Functions

Function	Web (Teacher)	Web (Student)	iOS and Android (Student)	Note
Real-time audio and video communication	✔	✔	✔	/
Real-time messaging	✔	✔	✔	/
Interactive Whiteboard	✔	✔ One-to-one Classroom ✔ Small Classroom ✘ Lecture Hall	✔One-to-one Classroom ✔ Small Classroom ✘ Lecture Hall	In a one-to-one classroom, both the teacher and students can draw on the whiteboard by default. In a small classroom, students cannot draw on the whiteboard by default, but the teacher can give a student the permission of drawing on the whiteboard. In a lecture hall, students can never draw on the whiteboard.
Whiteboard follow	✔	✔	✔	The teacher can enable "whiteboard follow". When the teacher is moving the whiteboard or turning pages, the whiteboard area that students see will be consistent with the teacher's whiteboard area.
Uploading files (PPT, Word, PDF, audio files or video files)	✔	✘	✘	Only teachers can upload files to the classroom.
Students raising hands	✔	✔	✔	In a lecture hall, students do not send their audio and video by default, but they can "raise their hands" to apply for interacting with the teacher. The teacher can approve or decline the application.
Screen sharing	✔	✔	✔	The teacher can share the screen.
Recording and replay	✔	✔	✔	The teacher can start recording and record the class for at least 15 seconds. After the recording finishes, a link for replaying the class will be displayed in the message box.

Compatibility

Agora e-Education supports the following platforms and versions:

• iOS 10 or later. We do not test Agora e-Education on iOS 9 updates.
• Android 4.4 and later.
• Web Chrome 72 and later. We do not test Agora e-Education on browsers.

Restrictions

See Restrictions.

Get started

Prerequisites

Make sure you make the following preparations before compiling and running the sample project.

Get an Agora App ID

Follow these steps to get an Agora App ID:

1. Create an account in Agora Console.
2. Log in to Agora Console and create a project. Select "App ID + App Certificate + Token" as your authentication mechanism when creating the project. Make sure that you enable the App Certificate of this project.
3. Get the App ID of this project in Project Management page.

Pass the basic HTTP authentication

Before using the Agora RESTful APIs, you need to generate the Authorization parameter with the Customer ID and Customer Certificate provided by Agora and pass the Authorization parameter in the HTTP request header for authentication. For details, see the steps of basic HTTP authentication.

Get a Netless sdkToken and register with Agora Cloud Service

Follow these steps to get a Netless whiteboard sdkToken:

1. Create an account in Netless Console.
2. Log in to Netless Console and get the sdkToken in the Key management page.

You need to register the sdkToken of the whiteboard to the Agora cloud server.

1. OpenAgora Console
2. EditProject Management, select the function module and click "update the token" to register.

Run the sample project

See the following documents to compile and run the sample project:

• Run the Android project
• Run the iOS project
• Run Web and Electron project

Use Agora Edu Cloud Service

Agora provides Agora Edu Cloud Service for developers who are not good at back end development. You can call the RESTful APIs of Agora Edu Cloud Service to quickly implement managing the states of classrooms and the permissions of users on the back end. For details, see Agora Edu Cloud Service.

FAQ

See Trouble Shooting.

sendMessage(peerAccount, text) 没有作用（急）

已确保接收方是在频道内，且peerAccount也是有效的
这个版本的发消息也没有成功与失败的回调，所以不知道发生什么事情。
demo里也没有用上这个api。
非常急，望回

recording server的链接失效了

新的链接应该是：https://github.com/AgoraIO/Basic-Recording/tree/release/2.3.3/On-Premise-Recording-Nodejs

打包后的安装程序在windows安装的目录怎么修改？

打包后的win安装程序自动装到c盘的\Users\xxx\AppData\Local\Programs\agora-education-demo，请问可以在安装时自定选择安装目录或者在代码里把agora-education-demo改成别的可以吗？

Problem with Screen Sharing

Hi, I am trying release-2.1.0(agora-education-demo 0.2.1) to check screen sharing.

After entering Classroom as a teacher, click "Screen Share" button, my client preview seems to be working, but student side computers cannot see the shared screen, and they get black screen, when teacher click "Screen Share" again(to be off), student side computers see white screen.

Is there any work around for this issue? Or something I need to fix for the code?

Thanks,

提议：升级版本时请告知需要升级的文件和配置

升级版本时请告知需要升级的文件和配置
如0.4.7升级到0.4.8，若只更新AgoraSDK是升级不成功的，需要替换掉app文件夹下的app.html

The issue seems to be related to redis:alpine image. I tried changing the somaxconn value to something greater from inside the redis:alpine container but it says the file system is read-only.

sendStreamMessage 有没有使用案例？

node sdk 里面调用sendStreamMessage 传输了数据但是安卓端没有收到

除此之外，sendStreamMessage 是TCP上传输数据么还是websocket ？

setAudioRecordingDevice(deviceid) 不起作用

已确保deviceId是没有错

调用stopAudioPlaybackDeviceTest方法后，setAudioPlaybackVolume与audiodevicevolumechanged的监听都失效了

调用stopAudioPlaybackDeviceTest方法后，setAudioPlaybackVolume与audiodevicevolumechanged的监听函数都失效了，只有在播放声音时这两个方法才再次生效

web 信令不稳定

你好，请问原生版信令SDK什么时候可以上线，发现web sdk，经常会出现一些如下问题，发送，接收方都在频道内，但是接收方有时会接收不到什么消息，但没有掉线的回掉；
也有出现收到广播的消息，却不能较即时收到P2P消息，而是阻塞一段时间一次性收到P2P的消息；
登出信令现在只有101与102两个码，不管是被T还是真正断网都只返回102，这样做不到原生SDK的被T提示，也没法做到重连的功能。

运行 chrome://gpu 发现我的项目里的gpu都禁止掉了，但你们demo查看是开启了，搜索demo了没找到相关的设置方法，请问这个是不是在Electron里是有设置的

你好，我们部署了服务端录制功能，但我们需要做一个录制屏幕（带远近端声音）的录制用于回放，请问这个有什么方法吗？

what is agora version?

升级到[email protected]之后无法进入直播间

看到 doc有agoraRtcEngine.addInjectStreamUrl(url, config) ⇒ number这个方法，只有2.3.2才有，所以升到2.3.2-alpha

升级后运行进入直播间时弹出系统弹框：This process has crashed.

请问升级后需要做什么配置调整吗

当USB麦克风被拔下时，audiodevicestatechanged回调函数没有被触发

检测到两个录音设备，当拔下一个时，音频设备变化回调 (onAudioDeviceStateChanged)函数没有被触发，
导致无法重新加载设备，所以也无法指定一个新的deviceID,就没法测试麦克风是否可用。官方demo也有这个问题。

参数写错了

https://github.com/AgoraIO/ARD-eEducation-with-Electron/blob/a156f7df4cf921c454c3535791039a8630a43372/client/app/AgoraSDK/AgoraSdk.js#L749

除此之外感觉这两个函数没用哦，我服务端录制开启了手动模式。然后再次通过这个函数开始录制但是没有用。

当摄像头被占用后，调用startPreview会导致程序闪退且没有日志可捕获

用的是最新的demo测试，测试步骤如下：
1。利用别的程序，如QQ占用摄像头；
2. 打开demo程序，此时黑色（正常）；

3.进入教室后，再退出再登录就会发生闪退，查看代码是在startPreview后闪退的；

请问这个错误日志怎么才能拿到，或者catch掉，而不是闪退；

this.rtcEngine.videoSourceJoin(token, ...) 传入token屏幕分享无反应

已经在声网控制台开启app Certificate

传入从接口生成好的channel和uid对应的token:

token = '0069exxxxx'
uid = 12345
channel = 'class1'
console.log(this.rtcEngine.videoSourceJoin(token, channel , info, uid));

videoSourceJoin返回0，

但下面这个成功的回调没有执行，userjoined 回调也没有执行，屏幕分享也没有起作用。

this.rtcEngine.once('videosourcejoinedsuccess', uid => {
        // clearTimeout(timer)
        console.log('success')
        this.sharingPrepared = true
        resolve(uid)
});

我用同样的传入方式调用 this.rtcEngine.joinChannels 是有起作用的。

setAudioPlaybackDevice 不起作用

你好，setAudioPlaybackDevice 不起作用。
setAudioPlaybackDevice(deviceid) {
return this.rtcengine.setAudioPlaybackDevice(deviceid);
}

对应管网里的这个方法吧

document 上传功能有做吗？ 我想接这个功能怎么接

调用startAudioPlaybackDeviceTest在播放音乐时，如果触发了stopAudioRecordingDeviceTest停止mic的录制同时也会停止了音乐的播放

苹果系统CPU占用率过高

您好，我发现node版本SDK在苹果系统CPU占用率太高了，运行一会就风扇转个不停，卡的很。不知道是我配置的版本还是什么原因。

请问这是什么问题

信令SDK版本过低

我看到agora_sig_sdk.dll的版本是1.2.1，根据你们的发布更新日志 是在1.2.1 版 （发布于 2018 年 3 月 20 日）。
但是很多api没有开放出来，如setAttr,getUserAttr,onUserAttrResult,onMessageSendSuccess等非常重要的API。
请问是不是只是AgoraSig-1.2.1.3.js没做兼容而已，dll其实是通用的，我简单试了下AgoraSig-1.2.1.3.js里的session.socket.on("notify", function(msg)...
也没发现有这些回调回来
