returns null. First of all I suggest you to write the if condition more null safety:
if("1".equals(monthstring))
will never throws a NPE.
Furthermore: monthstr is null.
you passed it with a null value.
Unfortunality you dont post enough code to see the reason for that.
Please post the whole class UserDetailsActivity
