org.json.JSONException: Value at 0 of type org.json.JSONArray cannot be converted to JSONObject
I have values of the states and cities of India stored in JSON. That code will be to big to put up in here so I tried the same thing but with only states. But that file is not getting compiled.

jsonArray is pointing towards incorrect reference. If you check your raw JSON, it's containing an array inside an array.
[ // -> Outer JSONArray
[ // -> Inner JSONArray
{ // -> JSONObject
"State Name":"Andaman & Nicobar Islands"
},....
]
]
Replace this:
JSONArray jsonArray = new JSONArray(response);
With:
JSONArray outerJSONArray = new JSONArray(response);
JSONArray jsonArray = outerJSONArray.getJSONArray(0)
