      This document describes how to quickly run the TRTC demo for React Native.

      Environment Requirements

      React Native 0.63 or later
      Node (later than v12) & Watchman
      Developing for Android:
      Android Studio 3.5 or later
      Devices with Android 4.1 or later
      Developing for iOS and macOS:
      Xcode 11.0 or later
      OS X 10.11 or later
      A valid developer signature for your project
      For how to set up the environment, see the React Native official document.

      Prerequisites

      Directions

      Step 1. Create an application

      1. Log in to the TRTC console overview page, click Create Application.
      2. In the popup page, select RTC Engine, enter the application name, and then click Create.
      
      
      

      Step 2. Get your SDKAppId and SecretKey

      After your application created, you can get your SDKAppID and SDKSecretKey on Basic informaction. SDKAppID and SDKSecretKey is needed for running demo.
      
      
      

      Step 3. Download the sample code

      Go to GitHub to download the SDK and demo source code.
      git clone https://github.com/LiteAVSDK/TRTC_ReactNative.git

      Step 4. Configure the project

      1. Open the file downloaded previously, find and open /TRTC-Simple-Demo/debug/config.js, and set the following parameters:
      SDKAPPID: A placeholder by default. Set it to the actual SDKAppID.
      SDKSECRETKEY: A placeholder by default. Set it to the actual key.
      Note
      The method for generating UserSig described in this document involves configuring SDKSECRETKEY in the client code. In this method, SDKSECRETKEY may be easily decompiled and reversed, and if your key is disclosed, attackers can steal your Tencent Cloud traffic. Therefore, this method is only suitable for the local execution and debugging of TRTC-Simple-Demo.
      The best practice is to integrate the calculation code of UserSig into your server and provide an application-oriented API. When UserSig is needed, your application can send a request to your server for a dynamic UserSig. For more information, see How do I calculate UserSig during production?.

      Step 5. Configure permission requests

      You need to configure permission requests in order to run the demo.

      Android

      1. Configure application permissions in AndroidManifest.xml. The TRTC SDK requires the following permissions:
      <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" />
      Do not use android:hardwareAccelerated="false". Disabling hardware acceleration will result in failure to render remote videos.
      You need to request audio and video permissions manually for Android.
      if (Platform.OS === 'android') {
        await PermissionsAndroid.requestMultiple([
          PermissionsAndroid.PERMISSIONS.RECORD_AUDIO, //For audio calls
          PermissionsAndroid.PERMISSIONS.CAMERA, // For video calls
        ]);
      }

      iOS

      1. Configure application permissions in Info.plist. The TRTC SDK requires the following permissions:
      <key>NSCameraUsageDescription</key>
      <string>You can make video calls only if you grant the app camera permission.</string>
      <key>NSMicrophoneUsageDescription</key>
      <string>You can make audio calls only if you grant the app mic permission.</string>

      Step 6. Build and run the project

      Run npm install.

      Android

      1. Start Metro in the demo directory.
      npx react-native start
      2. Open a new window in the demo directory and start debugging.
      npx react-native run-android

      iOS

      1. Run pod install in the demo iOS directory to install dependencies.
      2. Start Metro in the demo directory.
      npx react-native start
      3. Open a new window in the demo directory and start debugging (if an error occurs, please use Xcode to debug your project).
      npx react-native run-ios
