This is not possible without manually processing the results. So after receiving the json data as a response, you need to check if the suggested country is the same as the user's country and if it is then do not display it in the textfield.
A JSON response looks like this: In the value field you can check the country and decide whether or not to display it by comparing it to the user's country that needs to be set somewhere in your App.
I believe the JSON response will be save in a List<HashMap<String, String>>
So you can loop over it and omit the country.
