I've been testing your repro sample. To have the MediaElement working, some details are missing. The first point is the experimental flag. MediaElement is in preview and you need the use the following flag: Device.SetFlags(new string[] { "MediaElement_Experimental" }); Then, if you want to auto play the video, you can use the Autoplay property. If you want to start playback by pressing the Play button, you need to handle the Click event and use the MediaElement Play method.

void Button_Clicked(object sender, System.EventArgs e)
{
     MediaPlayer.Play();
}

Please, test when you can the attached sample (is your sample modified): Issue9785.zip

@jsuarezruiz You are right that I forgot to add Device.SetFlags(new string[] { "MediaElement_Experimental" }); in Android project. After adding this I have noticed that the media player is still not displaying. Then I have changed this:

        <MediaElement Source="https://sec.ch9.ms/ch9/5d93/a1eab4bf-3288-4faf-81c4-294402a85d93/XamarinShow_mid.mp4"
                      ShowsPlaybackControls="True" VerticalOptions="StartAndExpand"/>

to this

        <MediaElement Source="https://sec.ch9.ms/ch9/5d93/a1eab4bf-3288-4faf-81c4-294402a85d93/XamarinShow_mid.mp4"
                      ShowsPlaybackControls="True" VerticalOptions="FillAndExpand"/>

So when you have VerticalOptions="StartAndExpand" it is not working but if change to VerticalOptions="FillAndExpand" it is working.

I had the same issue now have implemented: VerticalOptions="FillAndExpand"

I only see an issue with no playback when the video source is a local resource on android.

I only see an issue with no playback when the video source is a local resource on android.

I have the same issue, but for some reason It works after hot reloading the page

[Gogsi]

As a temporary workaround I manually play the video and resize it to refresh the view

Device.StartTimer(TimeSpan.FromSeconds(1), () =>
            {
                videoPlayer.Play();

                videoPlayer.ScaleTo(0.99f);
                videoPlayer.ScaleTo(1.00f);

                return false;
            });

We also can confirm this issue on Android 10 (API Level 29) with the video loaded from local resources.

This is still happening with the Toolkit version. There is a couple of workarounds already mentioned.

• It seems to work if you use FillAndExpand
• Specify a width- or heightrequest
• Do the little scale trick

Still good to take a look what is going on and hopefully fix it :)

I was about to give up on using "mediaElement". Luckily I saw this thread so I was able to add the "FillAndExpand" attribute. Now it works fine. I didn't need to add storage access to the manifest, nor did I need to set the experimental flag.

Same Issue in 2022 as this not been fixed yet? Even with this am getting nothing display though am using https://github.com/Tyrrrz/YoutubeExplode to covert to stream might be causing a dealy possilby will youtube stream support come in eventually

[apovetkin]

I have same issue.

Asked question here https://docs.microsoft.com/en-us/answers/questions/939040/mediaelement-is-not-working-for-xamarin-android.html

Any ideas why it's not show up?

Had the same problem when media element was contained in a grid. This is what I found:

The grid had 2 rows. Media element is in the second row. Upper row had a label and a button.

1. Containing grid had a RowDefinitions='Auto,*' Media element's VerticalOptions='FillAndExpand' Media element was not visible.
2. Containing grid had a RowDefinitions='*,*' (or '*,6*' for that matter) Media element's VerticalOptions='FillAndExpand' Media element was visible.
3. Containing grid had a RowDefinitions='*,*' (or '*,6*' for that matter) Media element's VerticalOptions='StartAndExpand' The video itself was not visible but the media element took some space (could see it's "BackgroundColor").

Adding this up to the discussion above leads me to believe that it is highly probable that the media element does not request for space(WidthRequest?\HightRequest) from it's parent after assessing the size of the video.
