Answer 1

Method 1: Using Gson

Create a class

public class RequestJson {
     String email;
     public RequestJson(String email){
          this.email = email;
     }
}

RequestJson requestJson = new RequestJson("user@gmail.com");

Change ApiInterface to

@POST("check_login.php")
Call<Login> checkEmail(@Field("x") RequestJson requestJson);

call directly with the object.

Method 2: Using JSONObject

JSONObject jsonObject = new JSONObject();
jsonObject.put("email", "user@gmail.com");
String email = jsonObject.toString();

Pass this string to Retrofit. You will get {"email":"user@gmail.com"} as request
