jsonArray JsonShow

having different errors mainly pertaining to the value of i variable.......any thoughts?

CodeChallenge.java 
JSONArray jsonShows = jsonData.getJSONArray("Shows");
for (int i=0;  i<jsonShows.length(); i++); {
  JSONObject showsObject = jsonShows.getJSONObject(i);
  Log.i("CodeChallenge", showsObject.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
        }
    ]

I am having the same problem and I don't think our code looks really different.... did you find out what was wrong?

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

for (int i = 0; 1 < jsonShows.length(); i++){
  JSONObject show = jsonShows.getJSONObject(i);

  Log.i("CodeChallenge", show.getString("title"));
}

Try changing your "Shows" to just lower s "shows"

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

to

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

That is what I believe the JSONArray name value is...

Cheers! Stephen

Ok my code does not have any compiler errors so I must be logging wrong somehow. Should I put the "title" into a var before using in the Log call? Not sure if that would make any difference or not,

I think what will solve your problem is just the letter "S" to a small "s" in your array call. I found my problem, I had the number 1 in my for loop instead or the "i" like it should of been (DOH!).... I hope your code work once you get that crazy "S" under control, silly "S" stop being on difficult :)

Cheers! Stephen
