Log.i method is not compiling

Not sure why it is not compiling

CodeChallenge.java 
// JSONObject 'jsonData' was loaded from data.json
JSONArray jsonShows = jsonData.getJSONArray("shows");
for (int i = 0; i < jsonShows.length(); i++) {
    JSONObject show = jsonShows.getJSONObject(i);
    Log.i(CodeChallege, show.getString("title"));
}
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
        }
    ]
}

From what you had originally, you just had to check the spelling and make CodeChallenge a string literal.

// JSONObject 'jsonData' was loaded from data.json
JSONArray jsonShows = jsonData.getJSONArray("shows");
for (int i = 0; i < jsonShows.length(); i++) {
    JSONObject show = jsonShows.getJSONObject(i);
    Log.i("CodeChallenge", show.getString("title"));
}

Hello,

You need to make the first parameter of Log.i() into the string "CodeChallenge" and not the undefined variable CodeChallenge. Also, I'd recommend that you take a look at the spelling of CodeChallenge.

This is what I have now and it doesn't work either. I'm stuck on this can you explain it better? Thanks!

JSONArray jsonShows = jsonData.getJSONArray("shows");

String CodeChallenge;
for (int i = 0; i < jsonShows.length(); i++) {
    JSONObject show = jsonShows.getJSONObject(i); 
    CodeChallenge = show.getString("title");
    Log.i(TAG, CodeChallenge);
}
