Cant get permissions to work for media plugins!

Hi guys!

I followed https://github.com/jamesmontemagno/MediaPlugin on how to fix permissions for Andriod for camera and browsing pictures. I still get error for "Cannot throw 'Plugin.Media.Abstractions.Mediapermission' on thread..." i have been trying to fix this for a while and can somone be so kind and check my code?

Thank you beforehand!
