	<key>NSMicrophoneUsageDescription</key>
	<string>use microphone to start video call</string>

	<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" />

Setup CrossCurrentActivity plugin in MainActivity:

public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
    protected override void OnCreate(Bundle savedInstanceState)
    {
        TabLayoutResource = Resource.Layout.Tabbar;
        ToolbarResource = Resource.Layout.Toolbar;
        PlatformOpenTokService.Init();
        base.OnCreate(savedInstanceState);
        
        // ==== Add this line ==== //
        CrossCurrentActivity.Current.Activity = this;
	// ==== ............. ==== //

        Forms.Init(this, savedInstanceState);
        LoadApplication(new App());
    }
}

Samples

The sample you can find here: https://github.com/AndreiMisiukevich/OpenTok-Xamarin.Forms/tree/master/Xamarin.Forms.OpenTok.Sample

Use CrossOpenTok.Current for accessing OpenTok service.

Full api you can find here: https://github.com/AndreiMisiukevich/OpenTok-Xamarin.Forms/blob/master/Lib/Xamarin.Forms.OpenTok/Service/IOpenTokService.cs

Firstly you should setup your service

CrossOpenTok.Current.ApiKey = keys.ApiKey; // OpenTok api key from your account
CrossOpenTok.Current.SessionId = keys.SessionId; // Id of session for connecting
CrossOpenTok.Current.UserToken = keys.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(!CrossOpenTok.Current.TryStartSession())
{
    return;
}
//Session is starting, you may show Chat Page

Use OpenTokPublisherView and OpenTokSubscriberView for showing video from your camera and for recieving video from another chat participant. Just put them to any laouyt as you wish. When session was started, they would recieve video.
