Xmarin.Forms samples for the MediaPlayer …
Simple Xamarin, UWP & WPF samples for the MediaPlayer …
and for those interested some links about the tricks of this library and examples in the wiki section...

Notes and warnings

This is only a preview, so there are missing features. If you are kind and ask for them, perhaps we'll implement them. Otherwise, as is is opensource contribute. PR (pull requests) are wellcome.

Android emulator

12/01/2019 - The mediaplayer control isn't working well in Android emulator, whereas same features work on a physical device.

Current platform support

platform	sample	build	state
UWP	XF.UWP		90 % audio
iOS	XF.iOS		60 % audio
Android	XF.Android		90 % audio
MacOS	XF.Mac		60 % audio
WPF	XF.WPF		70 % audio

Setup

• Available on NuGet: https://www.nuget.org/packages/ZPFMediaPlayer
• For Xamarin.Forms install into your Main and Client projects.

How to use

A Xamarin.Forms sample showing how to use MediaPlayer is in this Git, but here are the basics ...

authorizations

iOS and MacOS - Info.plist

If you wish to access to streamning sites you should add folowing lines to your Info.plist.

	<key>NSAppTransportSecurity</key>
	<dict>
		<key>NSAllowsArbitraryLoads</key>
		<true/>
		<key> NSAllowsArbitraryLoadsInWebContent</key>
		<true/>
	</dict>

Initialization

Before using the MediaPlayer you should initialize it in the platform dependent project.

Start by adding the using at the header of each concerned file ...

using ZPF.Media;

for an Android project: MainActivity.cs: OnCreate:

...
MediaPlayer.Current.Init();  
LoadApplication(new App());

for a UWP project: App.xaml.cs: OnLaunched:

...
MediaPlayer.Current.Init();  
Xamarin.Forms.Forms.Init(e);
...

for a WPF project: MainWindow.xaml.cs: MainWindow():

...
ZPF.Media.MediaPlayer.Current.Init(this);
Forms.Init();
...

Play

MediaPlayer.Current.Play("http://freesound.org/data/previews/273/273629_4068345-lq.mp3");  

On WPF you should try .. catch the Play method for the moment:
[WPF] Fatal exception when playing special song

Native player

Android

Android.Media.MediaPlayer Player = (Android.Media.MediaPlayer)MediaPlayer.Current.Player;  

// Set the low-level power management behavior for the MediaPlayer on Android:
Player.SetWakeMode(Application.Context, Android.OS.WakeLockFlags.Partial);

WakeLockFlags Enum

Remark: The Android Player type will probably change in the future to the ExoPlayer. So check the doc on each release.

UWP

Windows.Media.Playback.MediaPlayer Player = (Windows.Media.Playback.MediaPlayer)MediaPlayer.Current.Player;  

WPF

System.Windows.Controls.MediaElement Player = (System.Windows.Controls.MediaElement)ZPF.Media.MediaPlayer.Current.Player; 

Code Sample

X = implemented, blank = not yet implemented

Next steps

• code review
• iOS, Mac, WPF, ...
• MediaExtractor (WPF)**
• sync native playlist with internal playlist (UWP, ...)
• check ExoPlayer on Android
• video
• enhance/(re)design sample application

How to build
