Android Question java.lang.NullPointerException

[badal405]

Hi,
Unexpectedly I am getting an error and I could not find out why. If i debug line by line I don't get any report but when i release the app and run again I am getting the following error.

** Activity (startup) Create, isFirst = true **
** Activity (startup) Resume **
** Activity (startup) Pause, UserClosed = false **
** Activity (update_gflc) Create, isFirst = true **
** Activity (update_gflc) Resume **
update_gflc_spinner6_itemclick (java line: 2162)
java.lang.NullPointerException

java.lang.NullPointerException

then i open the java file and look to the line number 2162 and i found following comments.

_col = (int) (2);
//BA.debugLineNum = 951;BA.debugLine="If fn.cCursor.GetString2(col)<>zone AND fn.cCursor.GetString2(col)<>Null Then'loading zone";
if ((mostCurrent._fn._ccursor.GetString2(_col)).equals(_zone) == false && mostCurrent._fn._ccursor.GetString2(_col)!= null) {
//BA.debugLineNum = 952;BA.debugLine="Spinner12.Add(fn.cCursor.GetString2(col))";
mostCurrent._spinner12.Add(mostCurrent._fn._ccursor.GetString2(_col));
//BA.debugLineNum = 953;BA.debugLine="zone=fn.cCursor.GetString2(col)";
_zone = mostCurrent._fn._ccursor.GetString2(_col);
};

Check for null before you check for any other value.
