Android: Datepicker Dialog causes crash?

I made an android app that sends date to mysql. It was successful, then I tried making a tab widget. Both tabs contain the same code but are two different classes now after doing this the date picker dialog started to crash when activated.

What is the causes to this?

It happens when the activity which is calling the dialog was finishing for some reason or another when it tried to show a dialog.

This is what you can do

Replace

dpd.show();

with

if(!((Activity) SickLeave.this).isFinishing())
{
    dpd.show();
}
