JSONArray

Hello everyone, I missed something, does it come from my JSONObject or just the 2nd parameter of my Log? or something else ? thank you in advance for your help.

CodeChallenge.java
// JSONObject 'jsonData' was loaded from data.json
JSONArray jsonShows = jsonData.getJSONArray("jsonShows");

for (int i = 0; i < 3; i++) {
  JSONObject jsonData1 = jsonShows.getJSONObject(i);

  Log.i("CodeChallenge", "jsonShows");
}
data.json
{
    "name":"Netflix Playlist",
    "shows":[
        {
            "title":"Doctor Who",
            "season":8,
            "episode":3
        },
        {
            "title":"Arrow",
            "season":1,
            "episode":10
        },
        {
            "title":"Portlandia",
            "season":4,
            "episode":5
        }
    ]
}

Ok i see my errors :

I replace: java JSONArray jsonShows = jsonData.getJSONArray("jsonShows"); by java JSONArray jsonShows = jsonData.getJSONArray("shows");

and the other error was in my loop i replace the 3 by java jsonShows.length()

and in the Log.i()...

So i get the badge now!
