https://tokbox.com/ https://www.vonage.com/

Setup

• Available on NuGet: Xamarin.Forms.Vonage

Platform	Version
Xamarin.iOS	9.0+
Xamarin.Android	19+

• Add Xamarin.Forms.Vonage nuget package to Xamarin.Forms shared project and to all platform-specific projects (iOS & Android)

iOS

• Set "Minimum system version" to "9.0" or higher in Info.plist (!)

• Setup Vonage by calling PlatformVonage.Init(this) in AppDelegate

public partial class AppDelegate : FormsApplicationDelegate
{
    public override bool FinishedLaunching(UIApplication app, NSDictionary options)
    {
        PlatformVonage.Init(this); // Setup Vonage
        Forms.Init();
        LoadApplication(new App());
        return base.FinishedLaunching(app, options);
    }
}

• Add messages for requesting permissions to Info.plist file

	<key>NSCameraUsageDescription</key>
	<string>Use camera to start video call</string>
	<key>NSMicrophoneUsageDescription</key>
	<string>Use microphone to start video call</string>

Android

• Setup Vonage by calling PlatformVonage.Init(this) in MainActivity

protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);
    PlatformVonage.Init(this); // Setup Vonage
    Forms.Init(this, savedInstanceState);
    LoadApplication(new App());
}

• Add permissions to Manifest file.

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

• checking for permission "WRITE_EXTERNAL_STORAGE" will return false from Android13 and not required.
• add READ_MEDIA_AUDIO, READ_MEDIA_IMAGES, READ_MEDIA_VIDEO from Android 13

Samples

Please open Xamarin.Forms.Vonage.sln if you want learn more about this library or run sample app

Use CrossVonage.Current for accessing Vonage service.

Full api you can find here: https://github.com/AndreiMisiukevich/Xamarin.Forms.Vonage/blob/main/lib/Xamarin.Forms.Vonage/IVonageService.cs

Firstly you should set up Vonage

CrossVonage.Current.ApiKey = "{YOUR_API_KEY}"; // Vonage API key from your account
CrossVonage.Current.SessionId = "{YOUR_SESSION_ID}"; // Id of session for connecting
CrossVonage.Current.UserToken = "{YOUR_USER_TOKEN}"; // User's token

Then check wheather you have enough permissions for starting a call and if everything is fine it will start a session.

if(!CrossVonage.Current.TryStartSession())
{
    return;
}
//Session is starting, you may show Chat Page

Use VonagePublisherView and VonageSubscriberView for showing video from your camera and for recieving video from another chat participant. Just put them to any laouyt you prefer. When session is started, they will recieve video/audio streams.
