Live Audio Room SDK Integration

Here’s what you need to do to use the Live Audio Room Kit SDK to make a karaoke app for TV:

Run the following code in the root directory of your project to add the ZegoUIKitPrebuiltLiveAudioRoom to your project directory:

flutter pub add zego_uikit_prebuilt_live_audio_room

Add the following line of code to your main.dart file to import the SDK:

import 'package:zego_uikit_prebuilt_live_audio_room/zego_uikit_prebuilt_live_audio_room.dart';

After you’ve completed these steps, you’ll be ready to use the Live Audio Room Kit SDK to create your own karaoke apps for TV.

Steps to Make Karaoke App for TV with Live Audio Room Kit

To access Live Audio Room Kit, you’ll need your userID and username. The roomID represents the live audio room you wish to join.

class LivePage extends StatelessWidget {
  final String roomID;
  final bool isHost;

  const LivePage({Key? key, required this.roomID, this.isHost = false}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: ZegoUIKitPrebuiltLiveAudioRoom(
        appID: yourAppID, // Fill in the appID that you get from ZEGOCLOUD Admin Console.
        appSign: yourAppSign, // Fill in the appSign that you get from ZEGOCLOUD Admin Console.
        userID: 'user_id',
        userName: 'user_name',
        roomID: roomID,
        config: isHost
            ? ZegoUIKitPrebuiltLiveAudioRoomConfig.host()
            : ZegoUIKitPrebuiltLiveAudioRoomConfig.audience(),
      ),
    );
  }
}

It’s simple to host virtual events and gatherings when you have the ability to create a live audio room at your fingertips. Simply create the room and share the unique roomID with your intended audience, and they will be able to join the live audio experience with you.

Configure project (for Android)

To properly incorporate the SDK into your Flutter project, you’ll need to follow a few key steps:

Open the your_project/android/app/build.gradle file and set the compileSdkVersion to 33.
In the app/src/main directory of your project, open the AndroidManifest.xml file and add the following permissions:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

To prevent the obfuscation of the public class names in the SDK during the build process, create a file named proguard-rules.pro in the android > app folder of your project. Add the following line to the file:

-keep class .zego. { *; }

Then, in the release section of the your_project/android/app/build.gradle file, include the following configuration code:

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

By following these steps, you can ensure that the SDK is successfully integrated into your Flutter project and your app can access the necessary functionality.

Configure project (for iOS)

If you want to configure your iOS project to add necessary permissions and disable Bitcode, here’s what you can do:

First, open the Podfile location in the your_project/ios directory. In the post_install do |installer| section, add the following code snippet to enable camera and microphone permissions for your app:

# Start of the permission_handler configuration
target.build_configurations.each do |config|
  config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
    '$(inherited)',
    'PERMISSION_CAMERA=1',
    'PERMISSION_MICROPHONE=1',
  ]
end
# End of the permission_handler configuration

Next, open the Info.plist file located in the your_project/ios/Runner directory. In the dict section, add the following lines of code to provide descriptions for the camera and microphone permissions that will be displayed to the user when they are requested:

<key>NSCameraUsageDescription</key>
<string>We need camera access to connect to a live</string>
<key>NSMicrophoneUsageDescription</key>
<string>We need microphone access to connect to a live</string>

To disable Bitcode, open the Runner.xcworkspace file located in the your_project > iOS directory. Select your target project and follow the instructions in the provided images to disable Bitcode.

By following these steps, you can easily add the necessary permissions and disable Bitcode in your iOS project.

Run a Demo.

Now, you can simply click the Run or Debug button and watch your application come to life on your chosen device with ease.
