Component Overview

TUIKaraoke is an open-source audio/video UI component. After integrating it into your project, you can make your application support the online karaoke scenario and try out the TRTC capabilities such as karaoke, seat management, gift giving/receiving, and text chat simply by writing a few lines of code. It also supports the iOS platform. Its basic features are as shown below:

Chat	Sound Effect Management

Component Integration

Step 1. Download and import the TUIKaraoke component

Go to GitHub, clone or download the code, copy the Source and Debug directories in the Android directory to your project, and complete the following import operations:

• Complete import in setting.gradle as shown below:

  include ':Source'
  include ':Debug'
  

• Add dependencies on TUIKaraoke to the build.gradle file in app:

  api project(':Source')
  

• Add dependencies on TRTC SDK and IM SDK to the build.gradle file in the root directory:

  ext {
   liteavSdk = "com.tencent.liteav:LiteAVSDK_TRTCl:latest.release"
   imSdk = "com.tencent.imsdk:imsdk-plus:latest.release"
  }
  

Step 2. Configure permission requests and obfuscation rules

Configure permission requests for your app in AndroidManifest.xml. The SDKs need the following permissions (on Android 6.0 and later, the mic access and storage read permission must be requested at runtime):

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />        // Use case: This permission is required for the floating window
<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.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.BLUETOOTH" />                  // Use case: This permission is required when a Bluetooth headset is used

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

For more information on relevant APIs, see TUIKaraoke.

// 1. Initialize
TRTCKaraokeRoom mTRTCKaraokeRoom = TRTCKaraokeRoom.sharedInstance(this);
mTRTCKaraokeRoom.setDelegate(this);
// 2. Log in
mTRTCKaraokeRoom.login(SDKAppID, UserID, UserSig, new TRTCKaraokeRoomCallback.ActionCallback() {
    @Override
    public void onCallback(int code, String msg) {
        if (code == 0) {
        // Logged in
        }
    }
});

Parameter description:

• SDKAppID: TRTC application ID. If you haven't activated the TRTC service, log in to the TRTC console, create a TRTC application, and click Application Info. The SDKAppID is as shown below:
  
• Secretkey: TRTC application key, which corresponds to SDKAppID. On the Application Management page in the TRTC console, the SecretKey is as shown below:
• userId: Current user ID, which is a string and can contain up to 32 bytes of letters and digits (special symbols are not supported). You can customize it based on your actual account system.
• userSig: Security protection signature calculated based on SDKAppID, userId, and Secretkey. You can click here to directly generate a debugging userSig online or calculate it on your own by referring to the TUIKaraoke demo project. For more information, see UserSig.

Step 4. Implement the online karaoke scenario

1. The anchor creates a room through TUIKaraoke.createRoom.

   int roomId = "Room ID";
   TRTCKaraokeRoomDef.RoomParam roomParam = new TRTCKaraokeRoomDef.RoomParam();
   roomParam.roomName = "Room name";
   roomParam.needRequest = false; // Whether your consent is required for listeners to speak
   roomParam.seatCount = 8;       // Number of seats in the room. Set it to `8`
   roomParam.coverUrl = "URL of room cover image";
   mTRTCKaraokeRoom.createRoom(roomId, roomParam, new TRTCKaraokeRoomCallback.ActionCallback() {
   @Override
   public void onCallback(int code, String msg) {
     if (code == 0) {
       // Room created successfully
     }
   }
   });
   

2. A listener enters the room through TUIKaraoke.enterRoom.

   mTRTCKaraokeRoom.enterRoom(roomId, new TRTCKaraokeRoomCallback.ActionCallback() {
   @Override
   public void onCallback(int code, String msg) {
       if (code == 0) {
       // Entered room successfully
       }
   }
   });
   

3. *A listener mics on through TUIKaraoke.enterSeat.

   // 1. A listener calls an API to mic on
   int seatIndex = 1;
   mTRTCKaraokeRoom.enterSeat(seatIndex, new TRTCKaraokeRoomCallback.ActionCallback() {
   @Override
   public void onCallback(int code, String msg) {
       if (code == 0) {
       // Mic turned on successfully
       }
   }
   });
   // 2. The listener receives the `onSeatListChange` callback and refreshes the seat list
   @Override
   public void onSeatListChange(final List<TRTCKaraokeRoomDef.SeatInfo> seatInfoList) {
   }
   

Note：

You can implement other seat management operations as instructed in TRTCKaraoke (Android) or by referring to the TUIKaraoke demo project.

4. Play back songs and try out the karaoke scenario
   You can get the music ID and URL to play back a song based on your business. For more information, see Music Playback APIs.

   // Play back the music
   mTRTCKaraokeRoom.startPlayMusic(musicID,url);
   // Stop the music
   mTRTCKaraokeRoom.stopPlayMusic();
   

After completing the previous steps, you can implement the basic karaoke features. If your business needs more features such as text chat and gift giving, you can integrate the following capabilities:

Step 5. Add the text chat feature (optional)

If you want the text chat feature between anchors and listeners, implement message sending/receiving as follows:
For more information on relevant APIs, see sendRoomTextMsg.

// Sender: Sends text messages
mTRTCKaraokeRoom.sendRoomTextMsg("Hello Word!", new TRTCKaraokeRoomCallback.ActionCallback() {
   @Override
   public void onCallback(int code, String msg) {
       if (code == 0) {
           // Sent successfully
       }
   }
});
// Receiver: Listens for text messages
mTRTCKaraokeRoom.setDelegate(new TRTCKaraokeRoomDelegate() {
 @Override
 public void onRecvRoomTextMsg(String message, TRTCKaraokeRoomDef.UserInfo userInfo) {
     Log.d(TAG, "Received a message from" + userInfo.userName + ": " + message);
 }
});

Step 6. Add the gift giving feature (optional)

If you want the gift giving and receiving features, implement gift giving, receiving, and displaying as follows:

// Sender: Customize `CMD_GIFT` to distinguish between gift messages
mTRTCKaraokeRoom.sendRoomCustomMsg("CMD_GIFT",date, new TRTCKaraokeRoomCallback.ActionCallback() {
   @Override
   public void onCallback(int code, String msg) {
       if (code == 0) {
           // Sent successfully
       }
   }
});
// Receiver: Listens for gift messages
mTRTCKaraokeRoom.setDelegate(new TRTCKaraokeRoomDelegate() {
   @Override
   public void onRecvRoomCustomMsg(String cmd, String message, TRTCKaraokeRoomDef.UserInfo userInfo) {
       if ("CMD_GIFT".equals(cmd)) {
           // Received a gift message
           Log.d(TAG, "Received a gift from" + userInfo.userName + ": " + message);
       }
   }
});
