# 多人音视频demo

demo使用liveKit实现多人音视频通话，通话信令和状态的维护通过imsdk实现。所以需要同时集成imsdk与livekit

## 1. 集成livekit

项目中的`livekit.zip`是livekit的maven库，使用时需发布到自己的maven私服上，
或者解压到本地maven缓存目录下（路径：`用户目录\.m2\repository\`），在App级的gradle中添加`mavenLocal()`引用

livekit使用的是google的protobuf，所以在项目中需要配置proto文件的路径。
在项目级gradle中添加
```
ext{
    generated = [
            protoSrc: "$projectDir/protocol",
    ]
}
```

gradle引用
```
//多人视频库
implementation "io.livekit.android:livekit:0.9.1"
implementation "com.google.protobuf:protobuf-java:3.15.1"
```

## 2. 集成imsdk

imsdk已经打包为aar放在app模块的libs目录中。

因为imsdk存储发送的消息使用了Room数据库，所以需要在项目中引入
```
def roomVersion = "2.4.1"
implementation("androidx.room:room-runtime:$roomVersion")
annotationProcessor("androidx.room:room-compiler:$roomVersion")
// To use Kotlin annotation processing tool (kapt)
kapt("androidx.room:room-compiler:$roomVersion")
// optional - Kotlin Extensions and Coroutines support for Room
implementation("androidx.room:room-ktx:$roomVersion")
// optional - RxJava2 support for Room
implementation("androidx.room:room-rxjava2:$roomVersion")
// optional - Guava support for Room, including Optional and ListenableFuture
implementation("androidx.room:room-guava:$roomVersion")
// optional - Test helpers
testImplementation("androidx.room:room-testing:$roomVersion")
// optional - Paging 3 Integration
implementation("androidx.room:room-paging:$roomVersion")
```

AndroidManifest需要配置PushService用于收发多人视频的信令
```
<service
    android:name="cn.wecloud.im.push.PushService"
    android:enabled="true" />
```

在Application中对imsdk初始化
```
//初始化SDK配置
WeCloud.initialize(this, HTTP_URL, WS_URL)
//注册多人会议事件处理
IMMessageManager.registerMultiMeetMessageHandler(MultiMeetMsgHandler(this))

//后台WS服务配置
//设置自动唤醒
PushService.setAutoWakeUp(true)
//创建通知通道
PushService.createNotificationChannel(
    this,
    "cn.wecloud.chatkitdemo",
    "后台运行",
    "消息渠道",
    NotificationManager.IMPORTANCE_HIGH,
    false,
    0,
    false,
    null
)
PushService.setDefaultChannelId(this, AndroidNotificationManager.DEFAULT_CHANNEL_ID)
PushService.setForegroundMode(true, 123, createForegroundNotification())
PushService.setDefaultPushCallback(this, MainActivity::class.java)
PushService.setNotificationIcon(R.drawable.ic_launcher_foreground)
```
