Configuring your Expo app to use this library

app.json

Make the following changes to your app.json file to enable usage of the Twilio Voice React Native SDK in your Expo application.

iOS

This library requires three permissions that need to be set in your app.json file.

{
 "expo": {
 ...,
 "ios": {
 ...,
 "infoPlist": {
 "NSMicrophoneUsageDescription": "Voice calling",
 "UIBackgroundModes": ["audio", "voip"]
 },
 "entitlements": {
 "aps-environment": "development"
 }
 }
 }
}

Consider modifying the "NSMicrophoneUsageDescription" string value for your use case and setting the "aps-environment" value to "production" for production builds.

Android

This library requires a Google Services JSON file to enable your Expo app to receive incoming calls. Make the following changes to your app.json file to support this.

{
 "expo": {
 ...,
 "android": {
 ...,
 "googleServicesFile": "./google-services.json"
 }
 }
}

Consider modifying the "googleServicesFile" string value to match your development environment.
