Xamarin Android Forms.Context obsolete - How to fix it in a dependent method?

I am getting a message saying FormsContext is obsolete. I saw numerous suggestions on how to fix it but none apply to my case below:

[assembly: Xamarin.Forms.Dependency(typeof(SoundMethods))]
namespace J.Droid
{
    public class SoundMethods : ISoundMethods
    {
        public void IsDeviceSilent()
        {
            AudioManager am = (AudioManager)Forms.Context.GetSystemService(Context.AudioService);
        }
    }
}

Can anyone suggest how I can fix this for my example?

I usually use the Plugin.CurrentActivity from James Montemagno.

Nuget: https://www.nuget.org/packages/Plugin.CurrentActivity

Github: https://github.com/jamesmontemagno/CurrentActivityPlugin

You have to initialize the plugin in your AppDelegate OnCreate:

CrossCurrentActivity.Current.Init(this, bundle);

Then in your services (or in any class in the Android Project) you can get the current context with this:

var context = CrossCurrentActivity.Current.AppContext

You can get the context in your constructor like this:

private Context _context;

public ContentPageRenderer(Context context) : base(context)
{
    _context = context;
}

And then access it with the _context variable.

You can add a method to init and pass the Context from the MainActivity:

  static Context _context;

        public static void Init(Context context)
        {
            _context = context;
        }


        public void IsDeviceSilent()
        {
            AudioManager am = (AudioManager)_context.GetSystemService(Context.AudioService);
        }

then, in MainActivity

SoundMethods.Init(this);
