  <p>in the tracking users part I have three "different" (they're the same for testing purposes) JSON strings within the original JSON. How do I go through the inner parameter (user_id[0]),(user_id[1]),(user_id[2])... of tracking_users in a for loop for android?</p>
  
  <p>I am turning my JSON into a string and then using 
  obj = new org.json.JSONObject(response) to change it into an object then I use
  String trackingusers=obj.getString("tracking_users") to get the three objects in the tracking_users variable.</p>
  
  <p>Thanks</p>
