json url

{   "data":[          "rawat","islamabad mor","kaak pull","lohi bher","koral chowk","gangal",          "khana bridge","zia masjid","kuri road","dhok kala khan","faizabad",          "pirwadhai mor","tanki stop i-8\/4","i-8\/3 stop","al shifa hospital","aiou",          "zero point","children hospital","f-8\/4","ali hospital"   ],   "success":1,   "status":200,   "status_message":"login successfull" } 

error: @ line

 jsonarray = jarray.getjsonarray(i); 

from json, jarray array of string , not array of jsonarray.
replace:

jsonarray = jarray.getjsonarray(i); stopnames = jsonarray.getstring(0); 

with:

stopnames = jarray.getstring(i);
