System.NotImplementedException: 'This functionality is not implemented in the portable version of this assembly

Question

I have added Plugin.MediaManager and Plugin.MediaManager.Forms into my xamarin forms project for playing video.

CrossMediaManager.Current.Init(this);

when I am trying to add above code, it shows error (No overload for method Init();)

But getting below exception on android when running the project with below line of code.

CrossMediaManager.Current.Init();

System.NotImplementedException: 'This functionality is not implemented in the portable version of this assembly. You should reference the NuGet package from your main application project in order to reference the platform-specific implementation.'

IOS and UWP apps are working fine, only android project has this issue. Please help me to fix this.

System.NotImplementedException: 'This functionality is not implemented in the portable version of this assembly. You should reference the NuGet package from your main application project in order to reference the platform-specific implementation.'

The above error often appears when the version of Android target is lower . Here is a similar issue that you can check https://github.com/martijn00/XamarinMediaManager/issues/437 .

In addition, in your case . You should make sure the format of video url is xxx.mp4 .The plugin couldn't support the url with such a format(player.vimeo.com/video/361089481).
