i tried to write "R.array."+dynamic_variable_array_name

but i failed..any help

Why don't you initialize your array before you refer it to the ArrayAdapter?

Array myArray = getMyArray();

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, myArray, android.R.layout.simple_spinner_item);

[Update]
Ok, i've just noticed ArrayAdapter.createFromResource doesn't work with non-resources. But this will work:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, myArray);

Try This

Spinner countrySpinner = (Spinner) findViewById(R.id.search_country);
CharSequence[] myArray = new CharSequence[]{
                "Qatar","UAE","India","America"
        };
ArrayAdapter<CharSequence> countryAdapter = new ArrayAdapter<>(getApplicationContext(), android.R.layout.simple_spinner_item,myArray);
        countryAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
countrySpinner.setAdapter(countryAdapter);
