Answer 1

Whenever you would like to call something from native (MAActivity.cs in your case), you have to use DependencyService.

For example:

1. Setup dependency service

   // PCL Project
   public interface INativePages
   {
       void StartMA();
   }
   
   // MonoDroid Project
   [assembly: Dependency(typeof(NativePages))]
   
   public class NativePages : INativePages
   {
       public void StartMA()
       {
           var intent = new Intent(Forms.Context, typeof(MAActivity));
           Forms.Context.StartActivity(intent);
       }
   }
   

2. Invoke in PCL

   // PCL Project
   DependencyService.Get<INativePages>().StartMA();
