android - Parsing JSON to Array Map Produces "The local variable may not have been initialized" -


i'm following tutorial ( http://mobile.dzone.com/news/android-tutorial-how-parse ) how ever // add items doddataitemobj dataitem string - string publiceventtype = d.getstring(publiceventtype); saying local variable publiceventtype may not have been initialized. points line jsonobject d = dataitems.getjsonobject(i); believe defined. i've tried no luck public string d; produces error code have mentioned.

i'd appreciate thoughts.

 string publiceventtype = d.getstring("publiceventtype");  

or

 string publiceventtype = d.getstring("publiceventtype"); // more conventionnal
