Permissions

info

If you’re using Expo, please refer to the Expo Integration Guide for setting up permissions.

Android

You need to add the below in your App's AndroidManifest.xml file.

AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Also in the same file in buildscript section in ext block make sure you have set minSdkVersion to 24.

build.gradle

buildscript {
  ext {
      buildToolsVersion = "29.0.2"
      minSdkVersion = 24
      compileSdkVersion = 29
      targetSdkVersion = 29
  }
}

iOS

You need to add the below in your App's Info.plist file.

Info.plist

<key>NSCameraUsageDescription</key>
<string>This is for Camera permission</string>
<key>NSMicrophoneUsageDescription</key>
<string>This is for Mic permission</string>

Also, update the minimum target version in the Podfile. Goto ./ios folder and open the Podfile. In the Podfile update the platform version to 12.0.

Podfile

platform :ios, '12.0'

Open the ios/App folder and run pod install this will create an App.xcworkspace open this and run the app.

Initialize CometChatCalls

The init() method initialises the settings required for CometChatCalls. The init() method takes a single paramater, that is the instance of CallAppSettingsBuilder class.

The CallAppSettings class allows you to configure three settings:

• App ID: CometChat app ID.
• Region: The region where you app was created.
• Host(host: string): This method takes the client URL as input and uses this client URL instead of the default client URL. This can be used in case of dedicated deployment of CometChat.

You need to call init() before calling any other method from CometChatCalls. We suggest you call the init() method on app startup, preferably in the index.js file.

Javascript

import { CometChatCalls } from "@cometchat/calls-sdk-react-native";

let appID = "APP_ID";
let region = "REGION";

const callAppSettings = new CometChatCalls.CallAppSettingsBuilder()
  .setAppId(appID)
  .setRegion(region)
  .build();

CometChatCalls.init(callAppSettings).then(
  () => {
    console.log("CometChatCalls initialization completed successfully");
  },
  (error) => {
    console.log("CometChatCalls initialization failed with error:", error);
  }
);

Typescript

import { CometChatCalls } from "@cometchat/calls-sdk-react-native";

let appID = "APP_ID";
let region = "REGION";

const callAppSetting = new CometChatCalls.CallAppSettingsBuilder()
  .setAppId(appID)
  .setRegion(region)
  .build();

CometChatCalls.init(callAppSetting).then(
  () => {
    console.log("CometChatCalls initialization completed successfully");
  },
  (error) => {
    console.log("CometChatCalls initialization failed with error:", error);
  }
);

Make sure you replace the APP_ID with your CometChat AppID and REGION with your App Region in the above code.

Parameter	Description
callAppSettings	An object of the CallAppSettings class
