hello guys.. this is JSONhelper class where i m parsing theurl and
finally in some another class i have written the follwing lines to get
the output
JSONhelper jsoNhelper=new JSONhelper(getApplicationContext());
jsoNhelper.getJson();
ArrayList<PlaceInformation> a=jsoNhelper.resultArrayList;
Log.v("First", " arrayList length="+ a.size());
but above lines show the length as zero... pls check the parser and
let me know where i m wrong. or pls provide the code to me..needed
