Put "List of Objects" in KrollDict with Titanium Android Module Development

I have a custom class declared in the module source code.

public class Friend{
    public String name;
    public List<String> phoneNumbers;
    public List<String> emailAddresses;

    public Friend(String name, List<String>emailAddresses, 
    List<String>phoneNumbers){
        this.name = name;
        this.emailAddresses = emailAddresses;
        this.phoneNumbers = phoneNumbers;
    }
}

I declared an Android Method in the Module

@Kroll.method
protected synchronized void getListOfObjects(){
    List<String> emailAddresses = Arrays.asList("[email protected]", "[email protected]", "[email protected]");
    List<String> phoneNumbers = Arrays.asList("1", "2", "3");

    List<Friend> friendList = new ArrayList<Friend>();
    friendList.add(new Friend("test1", emailAddresses, phoneNumbers));
    friendList.add(new Friend("test2", emailAddresses, phoneNumbers));
    friendList.add(new Friend("test3", emailAddresses, phoneNumbers));


    KrollDict kd = new KrollDict();
    kd.put("friendList", friendList);
    if (hasListeners("onShow")) {
        fireEvent("onShow", kd);
    }
}

Upon Calling the getListOfOjects method in the Titanium App

module.getListOfObjects();
module.addEventListener('onShow', function(e){
    Ti.API.info(JSON.stringify(e.friendList));
});

I cant seem to retrieve the friendList object.

The EXPECTED RESULT that I wanted to achieve would be like this

[
    {test1, ["[email protected]", "[email protected]", "[email protected]"], ["1", "2", "3"]},
    {test2, ["[email protected]", "[email protected]", "[email protected]"], ["1", "2", "3"]},
    {test3, ["[email protected]", "[email protected]", "[email protected]"], ["1", "2", "3"]}
]

The question is, HOW TO ACHIEVE THE EXPECTED RESULT BASED ON THE SAMPLE CODES ABOVE?

Another option is to return an object array like this:

KrollDict kd = new KrollDict();
Object[] obj = new Object[friendList.size()];

for (int i=0; i< friendList.size(); ++i){
    KrollDict model = new KrollDict();
    model.put("name", friendList.get(i).name);
    // ...
    obj[i] = model;
}

kd.put("list", obj);
fireEvent("onShow", kd);

That way you'll have an array in your event and don't need to convert that string into json later on.

If you want to use a JSON you can use TiConvert with toJSON, toJSONArray or toJSONString depending on your parameter. No need for Gson.

Convert the List object into JSON string using GSON and assign the result string to the KrollDict property

KrollDict kd = new KrollDict();
Gson gson = new Gson();
String friendListStr = gson.toJson(friendList);
kd.put("friendList", friendListStr);
