Problems with getting values from JSON object

I'm trying to get data once user logged in successfully but I never get any of results, what I am doing is next:

// response is my request to server
JSONObject obj = new JSONObject(response);
Log.d("RESPONSE",obj.toString());

so in log I do see values, like:

04-19 11:28:16.729: D/RESPONSE(3162): {"data":[{"loses":3,"username":"benedict","level":1,"strength":15,"experience":null,"gold":10,"password":"benedict","intelligence":5,"agility":10,"wins":5}],"status":true}

but once I try to read username for example like this: 

String username = obj.getString("username");

The code above ^ gives me nothing in my string.. Any help how I can retrieve data from JSONObject? Thanks!

Try this...

try {

        JSONObject object = new JSONObject(response);
        JSONArray Jarray = object.getJSONArray("data");

        for (int i = 0; i < Jarray.length(); i++) {

           JSONObject Jasonobject = Jarray.getJSONObject(i);
           String loose= Jasonobject.getString("loses");
           String username=Jasonobject.getString("username");
          ....... 
          ........



        }

    } catch (JSONException e) {

        Log.e("log_txt", "Error parsing data " + e.toString());
    }

You need to first get JSONArray which is data :

    JSONArray data = null;
        data = json.getJSONArray("data");
         for(int i = 0; i < data.length(); i++){
                JSONObject c = data.getJSONObject(i);
         String username = c.getString("username");
}

You can get idea about parsing JSON from HERE

your field username is in array data. To access into this try :

JSONObject obj = new JSONObject(response);
JSONArray array = obj.getJSONArray("data");

for(int i = 0; i < array.length(); ++i){
    JSONObject data = array.getJSONObject(i);
    String username = data.getString("username");
}

That is because the username is present in the data object, which happens to be an JSONArray. Get the data array from the response object, traverse through each JSONObject in the array, and from each object, extract your username.

Something like this:-

JSONObject obj = new JSONObject(response);
JSONArray data = obj.getJSONArray("data");
for(int i=0;i<data.length();i++){
    JSONObject eachData = data.getJSONObject(i);
    System.out.println("Username= "+ eachData.getString("username"));
}
