after getting json data in responsedata string not able parse it, , catching exception (3rd catch block) ,can tell problem , how overcome this. thanks

i think problem reading input stream .try function read input stream.

public static  string gettextfromstream(inputstream inputstream)throws ioexception{      stringbuilder total = new stringbuilder();     string line="";      bufferedreader reader = new bufferedreader(new inputstreamreader(inputstream));           while ((line = reader.readline()) != null) {             total.append(line);         }      return total.tostring(); } 

use :

string responsedata=gettextfromstream(inputstream);
