Integrating TUILiveRoom (Android)

Download PDF
Overview
TUILiveRoom is an open-source video live streaming scenario UI component. After integrating it into your project, you can enable your application to support interactive video live streaming simply by writing a few lines of code. It provides source code for Android, iOS, and mini program platforms. Its basic features are as shown below:
Note
All TUIKit components are based on two basic PaaS services of Tencent Cloud, namely TRTC and Chat. When you activate TRTC, the Chat SDK trial edition (which supports up to 100 DAUs) will be activated automatically. For Chat billing details, see Pricing.

Integration
﻿
Step 1. Download and import the TUILiveRoom component
Go to GitHub, clone or download the code, copy the Android/debug, Android/tuiaudioeffect, Android/tuibarrage, Android/tuibeauty, Android/tuigift, and Android/tuiliveroom directories to your project, and complete the following import operations:
Add the code below in setting.gradle:
include ':debug'
include ':tuibeauty'
include ':tuibarrage'
include ':tuiaudioeffect'
include ':tuigift'
include ':tuiliveroom'
Add dependencies on tuiliveroom to the build.gradle file in app:
api project(":tuiliveroom")
Add the TRTC SDK (liteavSdk) and Chat SDK (imSdk) dependencies in build.gradle in the root directory:
ext {
  liteavSdk = "com.tencent.liteav:LiteAVSDK_TRTC:latest.release"
  imSdk = "com.tencent.imsdk:imsdk-plus:latest.release"
}
﻿
Step 2. Configure permission requests and obfuscation rules
1. Configure permission requests for your application in AndroidManifest.xml. The SDKs need the following permissions (on Android 6.0 and later, the camera and storage read permissions must be requested at runtime.)
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus" />
2. In the proguard-rules.pro file, add the SDK classes to the "do not obfuscate" list.
-keep class com.tencent.** { *;}
﻿
Step 3. Initialize and log in to the component
// 1. Add a listener and log in
TUILogin.addLoginListener(new TUILoginListener() {
    @Override
    public void onConnecting() {      // Connecting …
        super.onConnecting();
    }
    @Override
    public void onConnectSuccess() {  // Connected
        super.onConnectSuccess();
    }
    @Override
    public void onConnectFailed(int errorCode, String errorMsg) {  // Failed to connect
        super.onConnectFailed(errorCode, errorMsg);
    }
    @Override
    public void onKickedOffline() {  // Callback for forced logout (for example, due to login from another device)
        super.onKickedOffline();
    }
    @Override
    public void onUserSigExpired() { // Callback for `userSig` expiration
        super.onUserSigExpired();
    }
});
TUILogin.login(mContext, "Your SDKAppID", "Your userId", "Your userSig", new TUICallback() {
    @Override
    public void onSuccess() {
    }
    @Override
    public void onError(int errorCode, String errorMsg) {
        Log.d(TAG, "errorCode: " + errorCode + " errorMsg:" + errorMsg);
    }
});
﻿
// 2. Initialize the `TUILiveRoom` component
TUILiveRoom mLiveRoom = TUILiveRoom.sharedInstance(mContext);
Parameter description:
SDKAppID: TRTC application ID. If you haven't activated TRTC, log in to the TRTC console, create a TRTC application, click Application Info, and select the Quick Start tab to view its SDKAppID.
﻿
﻿
Secretkey: TRTC application key. Each secret key corresponds to a SDKAppID. You can view your application’s secret key on the Application Management page of the TRTC console.
userId: ID of the current user, which is a string that can contain only letters (a-z and A-Z), digits (0-9), hyphens (-), and underscores (_). We recommend that you keep it consistent with your user account system.
UserSig: Security signature calculated based on SDKAppID, userId, and Secretkey. You can click here to quickly generate a UserSig for testing. For more information, see UserSig.

Step 4. Implement an interactive video live room
1. The anchor starts streaming.
mLiveRoom.createRoom(int roomId, String roomName, String coverUrl);
2. The audience member watches.
mLiveRoom.enterRoom(roomId);
3. Audience member and the anchor co-anchor together through TRTCLiveRoom#requestJoinAnchor.
// 1. The audience member sends a co-anchoring request
// `LINK_MIC_TIMEOUT` is the timeout period
TRTCLiveRoom mTRTCLiveRoom=TRTCLiveRoom.sharedInstance(mContext);
mTRTCLiveRoom.requestJoinAnchor(mSelfUserId + "requested to co-anchor", LINK_MIC_TIMEOUT
 new TRTCLiveRoomCallback.ActionCallback() {
 @Override
 public void onCallback(int code, String msg) {
     if (code == 0) {
         // The request is accepted by the anchor
         TXCloudVideoView view = new TXCloudVideoView(context);
         parentView.add(view);
         // The audience member turns on the camera and starts pushing streams
         mTRTCLiveRoom.startCameraPreview(true, view, null);
         mTRTCLiveRoom.startPublish(mSelfUserId + "_stream", null);
     }
 }
});
﻿
// 2. The anchor receives the co-anchoring request
mTRTCLiveRoom.setDelegate(new TRTCLiveRoomDelegate() {
 @Override
 public void onRequestJoinAnchor(final TRTCLiveRoomDef.TRTCLiveUserInfo userInfo, 
     String reason, final int timeout) {
     // The anchor accepts the co-anchoring request
     mTRTCLiveRoom.responseJoinAnchor(userInfo.userId, true, "agreed to co-anchor");
 }
﻿
 @Override
 public void onAnchorEnter(final String userId) {
     // The anchor receives a notification that the co-anchoring audience member has turned on the mic
     TXCloudVideoView view = new TXCloudVideoView(context);
     parentView.add(view);
     // The anchor plays the audience member's video
     mTRTCLiveRoom.startPlay(userId, view, null);
 }
});
4. Anchors from different rooms communicate with each other by calling TRTCLiveRoom#requestRoomPK.
// Create room 12345
mLiveRoom.createRoom(12345, "roomA", "Your coverUrl");
// Create room 54321
mLiveRoom.createRoom(54321, "roomB", "Your coverUrl");
﻿
// Anchor A:
TRTCLiveRoom mTRTCLiveRoom=TRTCLiveRoom.sharedInstance(mContext);
﻿
// 1. Send a cross-room communication request to anchor B
mTRTCLiveRoom.requestRoomPK(54321, "B", 
 new TRTCLiveRoomCallback.ActionCallback() {
 @Override
 public void onCallback(int code, String msg) {  
     // 5. Receive a callback of whether the request is accepted by anchor B
     if (code == 0) {
         // Accepted
     } else {
         // Declined
     }
 }
});
﻿
mTRTCLiveRoom.setDelegate(new TRTCLiveRoomDelegate() {
 @Override
 public void onAnchorEnter(final String userId) {
     // 6. Receive a notification about anchor B’s entry
     mTRTCLiveRoom.startPlay(userId, mTXCloudVideoView, null);
 }
});
﻿
// Anchor B:
// 2. Receive anchor A’s request
mTRTCLiveRoom.setDelegate(new TRTCLiveRoomDelegate() {
 @Override
 public void onRequestRoomPK(
    final TRTCLiveRoomDef.TRTCLiveUserInfo userInfo, final int timeout) {
     // 3. Accept anchor A's request
     mTRTCLiveRoom.responseRoomPK(userInfo.userId, true, "");
 }
 @Override
 public void onAnchorEnter(final String userId) {
     // 4. Receive a notification about anchor A’s entry and play anchor A's video
     mTRTCLiveRoom.startPlay(userId, mTXCloudVideoView, null);
 }
});
