Thanks for your time, but the solution didnt work.
After changing the Array to String, i got another error that "Initial_array" which is my string array name isnt found in my project.

Okay, Got it.

If you had added the planet values in the strings.xml file then change the value of array to string as the value is in string.xml file

var adapter = ArrayAdapter.CreateFromResource(
this, Resource.String.Initial_array, Android.Resource.Layout.SimpleSpinnerItem);

Do let me know, if it works

May be they don't uploaded the full tutorial. It is fetching the values of spinner from a resources file (i.e feom an array.xml file). It must be present in the project. If not then create a new one and write the resource value in it

Make sure your Values folder contains array.xml file, clean and rebuild your project
