Android : How do I get the key for each object in a dynamic JSON array?

How do I parse this object and get the name (key) for each person?

I can't just do String name = jsonObject.getString("name"); because the name is the key, not the value.

JSONArray jArray =

[{
    "Bob": {
        "last-name": "Jorgenson",
        "email": "b@b.com",
    },

    "Steve": {
        "last-name": "Bobson",
        "email": "steve@juno.com",
    },
}]

So what's the best way to parse it with the dynamically-named keys?

Disclaimer

Yes, this is pretty basic stuff. The dynamic bit is throwing me off though. There are many similar questions, but they usual involve a number of other factors. I can successfully download the data and store it in the JSONArray jArray above. I just need to figure out how to parse the data as outlined above.
