isn't this the correct way to add?
package com.example.model;
import java.util.Map;
import java.util.Set;
import java.util.HashMap;
public class Contact {
private String mFirstName;
private String mLastName;
private Map<String, String> mContactMethods;
public Contact(String firstName, String lastName) {
mFirstName = firstName;
mLastName = lastName;
/* This stores contact methods by name
* eg: "phone" => "(555) 555-1234"
*/
mContactMethods = new HashMap<String, String>();
}
public void addContactMethod(String method, String value) {
mContactMethods.add(method, value);
// TODO: Add to the contact method map
}
/**
* Returns the available contact methods. eg: phone, pager,
*
* @return The name of the contact methods that are available
*/

/**
