exoplayer and xamarin.android

Question

exoplayer and xamarin.android

I am totally new to xamarin. So, basically what I need help with is just to make a videoplayer which is able to play m3u8 hls stream and also pause it and step back a few seconds. I don't why but this task seemed easy at first but now I am really confused. I encoutered a problem meaning that I can't use PlayerView.setPlayer. VS says there's no such method so I don't know how to make this player work.

Was it changed in the updates? How do I make it happen?

using System;
using Android.App;
using Android.OS;
using Android.Runtime;
using Android.Views;
using AndroidX.AppCompat.App;
using Google.Android.Material.FloatingActionButton;
using Google.Android.Material.Snackbar;
using Com.Google.Android.Exoplayer2;
using Com.Google.Android.Exoplayer2.UI;
using Android.Widget;
using Toolbar = AndroidX.AppCompat.Widget.Toolbar;

 protected override void OnCreate(Bundle savedInstanceState)
        {

            PlayerView playerView;
            ProgressBar progressBar;
            ImageView btFullScreen;


            base.OnCreate(savedInstanceState);
            Xamarin.Essentials.Platform.Init(this, savedInstanceState);
            SetContentView(Resource.Layout.activity_main);

            Toolbar toolbar = FindViewById<Toolbar>(Resource.Id.toolbar);
            SetSupportActionBar(toolbar);

            FloatingActionButton fab = FindViewById<FloatingActionButton>(Resource.Id.fab);
            fab.Click += FabOnClick;

            playerView = FindViewById<PlayerView>(Resource.Id.playerview);

            Android.Net.Uri stream = Android.Net.Uri.Parse("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4");

            SimpleExoPlayer player = new SimpleExoPlayer.Builder(this).Build();
            PlayerView.SetPlayer(player);   // here I tried writing it differently but nothing worked.


        }

Hello,

Welcome to our Microsoft Q&A platform!

Xamarin.Android uses the C# code language, and its syntax is slightly different from that of Java. To set player for the playerView, try using playerView.Player = player command instead. The PlayerView.Player is both the get and set method for the property.

   playerView = FindViewById<PlayerView>(Resource.Id.playerview);  
     
   SimpleExoPlayer player = new SimpleExoPlayer.Builder(this).Build();  
   playerView.Player = player;

Best Regards,

Thanks a lot! It really helped! Is there a website or a manual where I could learn all of this exoplayer methods on Xamarin? I mostly try to adapt the code from Java but sometimes I end up in dead ends.

@Александр Прошанов To get what method the class provides, you could place the cursor of the mouse on the class and press F12 to check the source code.

yeah, I know about F12 but the thing is that there is a very limit list of things and I still don't understand how to call certain methods. For example, on the website of Exoplayer developer there's this:

// Create a player instance. SimpleExoPlayer player = new SimpleExoPlayer.Builder(context).build(); // Set the media item to be played. player.setMediaItem(MediaItem.fromUri(hlsUri)); // Prepare the player. player.prepare();

But I couldn't find anything about setMediaItem when I pressed F12.

Sorry, it's my mistake. Some methods may be in it's parent class. Try to search with the keyword as android Class SimpleExoPlayer to check the related document about the SimpleExoPlayer class, you could get all the fields and methods of the SimpleExoPlayer there.
