Xamarin Android Play Video From URL In Default Media Player

Xamarin Form Code

Create Xaml Page and add following Code

MainPage.xaml

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:d="http://xamarin.com/schemas/2014/forms/design"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             mc:Ignorable="d"
             x:Class="TestApp.MainPage">

    <StackLayout Margin="10,10,10,10">
        <Label Text="https://www.w3schools.com/html/mov_bbb.mp4" />
        <Button Text="Click Here to Play Video In Default Player" x:Name="btnPlayVideo" Clicked="BtnPlayVideo_Clicked" />
    </StackLayout>
</ContentPage>

MainPage.xaml.cs

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using TestApp.Services;

using Xamarin.Forms;

namespace TestApp

{

    // Learn more about making custom code visible in the Xamarin.Forms previewer

    // by visiting https://aka.ms/xamarinforms-previewer

    [DesignTimeVisible(false)]

    public partial class MainPage : ContentPage

    {

        public MainPage()

        {

            InitializeComponent();

        }

        private void BtnPlayVideo_Clicked(object sender, EventArgs e)

        {

            DependencyService.Get<IMediaService>().PlayVideo("https://www.w3schools.com/html/mov_bbb.mp4");

        }

    }

}

Now create the IMediaService Interface and add the following Code.

IMediaService.cs

using System;

using System.Collections.Generic;

using System.Text;

namespace TestApp.Services

{

   public interface IMediaService

    {

        void PlayVideo(string uri);

    }

}

Now Implement this interface in Platform specific

TestApp.Android

Create the MediaService.cs Class that Implement IMediaService Interface.

MediaService.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Android.App;

using Android.Content;

using Android.OS;

using Android.Runtime;

using Android.Views;

using Android.Widget;

using Plugin.CurrentActivity;

using TestApp.Droid.Services;

using TestApp.Services;

[assembly: Xamarin.Forms.Dependency(typeof(MediaService))]

namespace TestApp.Droid.Services

{

    public class MediaService : IMediaService

    {

        Context CurrentContext => CrossCurrentActivity.Current.Activity;

        public void PlayVideo(string uri)

        {

            Intent intent = new Intent();

            intent.SetAction(Intent.ActionView);

            intent.SetDataAndType(Android.Net.Uri.Parse(uri), "video/*");

            ((Activity)CurrentContext).StartActivity(intent);

        }

    }

}

Note:   For accessing the CurrentContext  Install the NuGet Package (Plugin.CurrentActivity) from NuGet Package Manager
