how to call platform specific page from xamarin.forms

Question

I am new to the xamarin app development, I have some questions :

1. Is it possible to call the platform specific page from the Xamarin.Form page?
2. Can I do Page Navigation from view model?

Let me explain clearly.

I have a Page XFView.xaml , XFView.xaml.cs and XFViewModel.cs in PCL (Xamarin.Forms) project from XFView.xaml.cs or XFViewModel.cs i want to call MAActivity.cs page which is present in Xamarin.Andriod project

I tried a lot but got getting any idea.

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();
