Dailymotion propose, sur son site Web, une grande liste de SDKs officiels, permettant de couvrir la grande majorité des plateformes existantes à l’heure actuelle:

Cependant, l’éditeur ne mets pas à disposition, des développeurs, de SDK utilisable dans le cadre d’une application Xamarin.Android. Fort heureusement, comme souvent avec Xamarin, il est possible de s’appuyer sur le code source du SDK en version Android, accessible depuis Github: https://github.com/dailymotion/dailymotion-sdk-android

Ainsi, il suffit de prendre le code source Java pour Android et de “l’adapter”, en C#, pour une application Xamarin. On a donc besoin d’une classe qui va représenter notre vue et qui va hériter de la classe “WebView” car le player DailyMotion s’appuie sur un objet HTML5 pour afficher les vidéos:

public class DailyMotionWebVideoView : WebView
{
    private WebSettings mWebSettings;
    private WebChromeClient mChromeClient;

    private String mEmbedUrl = "http://www.dailymotion.com/embed/video/{0}?html=1&fullscreen={1}&app={2}&api=location";
    private String mExtraUA = "; DailymotionEmbedSDK 1.0";
    private FrameLayout mVideoLayout;
    private FrameLayout mRootLayout;
    private Boolean mAllowAutomaticNativeFullscreen = false;

    public bool AutoPlay { get; set; }
    public bool IsFullScreen { get; set; }
    public WebChromeClient.ICustomViewCallback ViewCallback { get; set; }
    public VideoView CustomVideoView { get; set; }

    #region Constructors

    public DailyMotionWebVideoView(IntPtr javaReference, JniHandleOwnership transfer)
        : base(javaReference, transfer)
    {
        this.Initialize();
    }

    public DailyMotionWebVideoView(Context context)
        : base(context)
    {
        this.Initialize();
    }

    public DailyMotionWebVideoView(Context context, IAttributeSet attrs)
        : base(context, attrs)
    {
        this.Initialize();
    }

    public DailyMotionWebVideoView(Context context, IAttributeSet attrs, int defStyleAttr)
        : base(context, attrs, defStyleAttr)
    {
        this.Initialize();
    }

    public DailyMotionWebVideoView(Context context, IAttributeSet attrs, int defStyleAttr, bool privateBrowsing)

    public DailyMotionWebVideoView(Context context, IAttributeSet attrs, int defStyleAttr, int defStyleRes)

    #endregion

        mChromeClient = new DailyMotionWebChromeClient(this, this.Context);

        SetWebChromeClient(mChromeClient);
        SetWebViewClient(new DailyMotionWebViewClient(this));
    }

    public void CallPlayerMethod(string method)
    {

         * Otherwise the back button will be handled by the topmost Window, id-est the player controller

        mVideoLayout = new DailyMotionFrameLayout(this, this.Context);
        mVideoLayout.SetBackgroundResource(Android.Resource.Color.Black);
        mVideoLayout.AddView(video);

        var lp = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MatchParent, ViewGroup.LayoutParams.MatchParent);
        lp.Gravity = GravityFlags.Center;

        mRootLayout.AddView(mVideoLayout, lp);

    }

    public void HandleBackPress(Activity activity)

        else

    }

    public void SetAllowAutomaticNativeFullscreen(bool allowAutomaticNativeFullscreen)
    {
        mAllowAutomaticNativeFullscreen = allowAutomaticNativeFullscreen;
    }
}

Cette classe s’appuie sur 3 autres, représentant les objets nécessaires à la bonne exécution et au bon affichage de la vue:

public class DailyMotionWebChromeClient : WebChromeClient, MediaPlayer.IOnCompletionListener
{
    private readonly DailyMotionWebVideoView _dailyMotionWebVideoView;
    private readonly Context _context;

    public DailyMotionWebChromeClient(DailyMotionWebVideoView dailyMotionWebVideoView, Context context)
    {
        _dailyMotionWebVideoView = dailyMotionWebVideoView;
        _context = context;
    }

    public override View VideoLoadingProgressView
    {
        get
        {

            pb.Indeterminate = true;

            return pb;

    }

            if (child != null)

        }
    }

    public override void OnHideCustomView()
    {
        base.OnHideCustomView();

        _dailyMotionWebVideoView.HideVideoView();
    }

    public void OnCompletion(MediaPlayer mp)
    {
        _dailyMotionWebVideoView.HideVideoView();
    }
}

public class DailyMotionWebViewClient : WebViewClient
{
    private readonly DailyMotionWebVideoView _dailyMotionWebVideoView;

    public DailyMotionWebViewClient(DailyMotionWebVideoView dailyMotionWebVideoView)
    {

            return true;
        }

        return base.DispatchKeyEvent(e);
    }
}

A présent, il ne reste plus qu’à utiliser le player dans votre vue Android:

<TestDailymotionXamarin.DailyMotionWebVideoView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/dmWebVideoView" />

Maintenant, il reste à utiliser les méthodes permettant de charger la vidéo (par son id), gérer l’appui sur le bouton Back (pour quitter le plein écran si nécessaire), etc.:

private DailyMotionWebVideoView _dmView;

protected override void OnCreate(Bundle bundle)
{
    base.OnCreate(bundle);

    // Set our view from the "main" layout resource
    SetContentView(Resource.Layout.Main);

    _dmView = this.FindViewById<DailyMotionWebVideoView>(Resource.Id.dmWebVideoView);
    _dmView.SetVideoId("x10iisk");
}

public override void OnBackPressed()
{
    base.OnBackPressed();

    _dmView.HandleBackPress(this);
}

Et le tour est joué!

Attention à bien modifier le fichier manifest de votre application pour rajouter les propriétés/permissions suivantes:

android:hardwareAccelerated="true"

<uses-permission android:name="android.permission.INTERNET" />
