[ // json array node 
{  // json object node 
"Hospital": { // json object Hospital

To parse

JSONArray jr = new JSONArray("jsonstring");
for(int i=0;i<jr.length();i++)
{
   JSONObject jb = (JSONObject)jr.getJSONObject(i);
   JSONObject jb1 =(JSONObject) jb.getJSONObject("Hospital");
   String name =  jb1.getString("hospital_name");
   Log.i("name....",name);
}

Log

gives error here JSONObject jb = jr.getJSONObject(i); The method getJSONObject(String) in the type JSONObject is not applicable for the arguments (int) – Asim Zaidi Feb 18 '14 at 07:30
@Autolycus check whether its a valid json @ jsonlint.com – Raghunandan Feb 18 '14 at 07:31
JSONArray jr = new JSONArray(responseData); //JSONArray jr = jsonResponse.get for(int i=0;i – Asim Zaidi Feb 18 '14 at 07:43

You won't- its invalid JSON. You're missing most of your "" around field names.

Try this..

JSONArray tot_array = new JSONArray(response);

for(int i = 0; i< tot_array.length(); i++){
    JSONObject obj = tot_array.getJSONObject(i);
    JSONObject hospital_obj = obj.getJSONObject("Hospital");
    String hospital_name =  hospital_obj.getString("hospital_name");
}

Checkout this cool libray for parsing JSOn in Android its called GSON https://code.google.com/p/google-gson/ . Via this parsing this very simple.

Your string is not a valid JSON object. Check out jsonlint before trying to parse a string as JSON. After which, you can read about parsing JSON in Android. It's easy enough with the built-in org.json, but should be much easier if you use one of the many Java libraries out there that simplifies it further. You can look into Jackson or google-gson, two of the most capable utilities for your purpose.
