[Android] java.lang.classcastexception org.json.simple.jsonarray cannot be cast to org.json.simple.Jsonobject

Symptom)
While responding json object from the server side to Android side through HttpGet & HttpClient, I got this Unchecked Exception. The problem was neither request to server side nor response from server side. It was that I couldn't get JSON Object and parse it in the Android side.

Root Cause)
By mistake, I imported 2 different kinds of json libraries such as json-simple & json. As you can see in the picture right beneath, I imported org.json(blue box) & org.json.simple(red box) at the same time.

<Picture1> import clauses with org.json(blue box) and org.json.simple(red box)

That is the main reason why I got this exception.

Solution)
Just use only one JSON library org.json or org.json.simple like beneath.

Import org.json.simple.json.JSONException; Import org.json.simple.JSONObject; Import org.json.simple.parser.JSONParser; Import org.json.simple.parser.ParseException;
