I have a DatePickerDialog on my application. I am using DatePickerDialog because I need to show only month and year and it’s easier with dialog than datepicker. Its working fine in 4.0 or higher version but when I try to open the DatePickerDialog clicking an edittext in 2.3 the app get crashed.<\/p>\n
Here the code:<\/p>\n
