Access a JSON Object inside another JSON Object
<p>I have a JSON like this in my Android app :</p>

<pre><code>{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJtZWhkaS5hZ291emFsQGdtYWlsLmNvbSIsImV4cCI6MTQ2ODU1NTU4MjQ5MX0.A6-xNIZdbPv9mpjLO9jnnfbAeq1y-DC08SBUt2xBnYo",
    "expires": 1468555582491,
    "user": {
        "imageURL": "http://app.com/images/null",
        "email": "mail@gmail.com",
        "firstname": "mister",
        "lastname": "lalalala",
        "password": "$2a$10$VDGtxjz9w7f170Wc66OJi.1T",
        "id": "c19349c4044d34333",
        "language": "EN",
        "createdAt": "2015-07-07T14:15:54.000Z",
        "updatedAt": "2016-05-06T08:25:20.000Z"
    }
}
</code></pre>

<p>I can access to the "token" like this :</p>

<pre><code>String json = new String(bytes);
                JSONObject jsonObj = null;

     try {
            jsonObj = new JSONObject(json);
          } catch (JSONException e) {
             e.printStackTrace();
          }

Log.d("debug", "TOKEN : " + jsonObj.getString("token"));
</code></pre>

<p>But I don't know how to get the user email or firstname for example.
How can I do that ?</p>

<p>Thanks</p>
