so I have an activity with radiobuttons a datepicker and a timepicker that appear when you click two different buttons. Then I have another button underneath that puts text in a textview with the radio button selected, the day and time displayed on the bottom of the screen. The application stops running when I click the third button. The timepicker and the datepicker work just fine but when I click on the third button it crashes.
