Consumer Initialization

Consumer app must provide sdkToken.
accessToken is optional at constructor time and can be supplied later in authenticate.

const sdk = new ZyraTwilioWrapper({
  serverUrl: "https://your-backend.com",
  identity: "user_123",
  sdkToken: "YOUR_SDK_TOKEN",
  // optional:
  // accessToken: "TWILIO_ACCESS_TOKEN",
});

// Optional: provide access token during authenticate
await sdk.authenticate({ accessToken: "TWILIO_ACCESS_TOKEN" });

Android App Setup (Consumer App)

Update MainActivity.kt with VoiceActivityProxy hooks:

private val activityProxy = VoiceActivityProxy(this) { permission -> /* optional UX */ }

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    activityProxy.onCreate(savedInstanceState)
}

override fun onStart() { super.onStart(); activityProxy.onStart() }
override fun onStop() { activityProxy.onStop(); super.onStop() }
override fun onNewIntent(intent: Intent?) { super.onNewIntent(intent); activityProxy.onNewIntent(intent) }
override fun onDestroy() { activityProxy.onDestroy(); super.onDestroy() }

Update MainApplication.kt with VoiceApplicationProxy hooks:

private val voiceApplicationProxy = VoiceApplicationProxy(this)

override fun onCreate() {
    super.onCreate()
    voiceApplicationProxy.onCreate()
}

override fun onTerminate() {
    voiceApplicationProxy.onTerminate()
    super.onTerminate()
}

iOS App Setup (Consumer App)

Enable the following Xcode capabilities for the app target:

• Background Modes:
  • Audio, AirPlay, and Picture in Picture
  • Voice over IP
• Push Notifications

Use physical iOS devices for end-to-end call testing.
