Answer 1

First of all add this permissions to you Manifest:

Since Android 6.0 (API 23) you need also to request the permissions manually, add this code on your MainActivity.cs on your Xamarin.Android project:

if ((ContextCompat.CheckSelfPermission(this, Manifest.Permission.WriteExternalStorage) != (int)Permission.Granted)
            || (ContextCompat.CheckSelfPermission(this, Manifest.Permission.ReadExternalStorage) != (int)Permission.Granted))
        {
            ActivityCompat.RequestPermissions(this, new string[] { Manifest.Permission.ReadExternalStorage, Manifest.Permission.WriteExternalStorage }, REQUEST);
        }

Since Android 10 you may also need to add android:requestLegacyExternalStorage attribute to your Manifest like this:
