Handle Server Response in Android

After seeing the logcat you have posted, I feel you are fetching a JSON String as a response. When you get the response you want you will need to parse it.

So, in order that you are not held up afterwards in your code, I am helping you to continue after you get your response by giving following example of mine:

In one of my projects the response I got from the web service was:

{"checkrecord":[{"rollno":"abc2","percentage":40,"attended":12,"missed":34}],"Table1":[]}

In order to parse I did the following:

      JSONObject jsonobject = new JSONObject(result);
      JSONArray array = jsonobject.getJSONArray("checkrecord"); 
      int max = array.length();
      for (int j = 0; j < max; j++) 
   {
      JSONObject obj = array.getJSONObject(j);
      JSONArray names = obj.names();

     for (int k = 0; k < names.length(); k++) 
   {
      String name = names.getString(k);
      String value= obj.getString(name);  

   }

My JSONObject looks like this:

{"Table1":[],"checkrecord":[{"missed":34,"attended":12,"percentage":40,"rollno":"abc2"}]}

This is what the @gwa was trying to suggest. I just gave a code sample to you. Get your result first and determine whether it is valid.

Hope it helps
