Android : send string[] as JSON

I need help sending JSON to server side. This is how it should look:

 "myProfile": { "languages": [ "English", "German" ] }

So myProfile is a JSONObject that contains "languages" which is array of strings, right? Can someone help me send JSON to server?

JSONObject myProfileObject= new JSONObject();
JSONObject languagesObject = new JSONObject();

String[] languagesToServer = {"English", "German"};
languagesObject.put("languages", languagesToServer);
myProfileObject.put("myProfile", languagesObject);

This is creating "myProfile": {"languages":"[Ljava.lang.String;@42b82168"} which is obviously not good.

Can someone guide me please?
