Link Assemblies Task failed unexpectedly Error

I have added the Plugin.MediaManager.Forms in my xamarin forms project for video view. The project was working fine before adding this plugin in my project, but after i have added the plugin, the project doesn't compile for android giving " Link Assemblies Task failed unexpectedly " error. Can somebody help me ?

It works fine for IOS.

Moreover, the plugin installs with warnigs too :

Package 'Plugin.MediaManager.Forms 0.4.5' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETStandard,Version=v2.0'. This package may not be fully compatible with your project.
