java.lang.IllegalStateException: Activity has been destroyed on creating a datepicker dialog

Question

I am trying to create a DatePicker dialog from my main Activity using DialogFragments . I have extended the DialogFragment class and return the new datePickerDialog as per

http://developer.android.com/guide/topics/ui/controls/pickers.html

Here is my class code:

import java.util.Calendar;
import android.app.DatePickerDialog;
import android.app.DatePickerDialog.OnDateSetListener;
import android.app.Dialog;
import android.app.DialogFragment;
import android.os.Bundle;
import android.widget.DatePicker;

public class DatePickerFragment extends DialogFragment implements OnDateSetListener{

    @Override
    public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {
        // TODO set the date for the alarm      
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState){
        //set current date as default date
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        //Create New Instance of the datepicker dialog
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

}

I have a button on the main Acivity to fire the dialog:

public void setAlarm(View view){
        //TextView reminder_title  = (TextView) view.findViewById(R.id.reminder_title); 
        DialogFragment dateFragment = new DatePickerFragment();
        dateFragment.show(getFragmentManager(), "date picker");
    }

However, when I try to click on the button, I get an "java.lang.IllegalStateException: Activity has been destroyed" exception at the below line:

dateFragment.show(getFragmentManager(), "date picker");

Here is the activity log:

Answer 2

Faced similar issue today. It was simple. Just check the following on my button click:

if (!datePickerDialog.isAdded()) {

          datePickerDialog.setStartDate(year, month, day);
          datePickerDialog.show(getFragmentManager(), DATEPICKER_TAG);
}
else
{
  //you can replace or add,,ur wish
}

that's it
