You are trying to set the list of Custom Objects List<Country> By default array adapter takes list of String. List<String>.

You have to tweak your code to set List of Custom objects in spinner.

Android: How to bind spinner to custom object list?

This should solve your problem.

Uncomment your , You are not setting data to spinner anywhere..

ArrayAdapter countryAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, countries);
        pmcountry.setPrompt("--Select Country--");
        pmcountry.setAdapter(countryAdapter);
        pmcountry.setAdapter(new NothingSelectedSpinnerAdapter(countryAdapter,
                R.layout.contact_spinner_row_nothing_selected,this));
