I am trying to use an intentService from a fragment by using getSystemService which sets an alarm that send intent.But I am getting a nullpointer exception at getsystemservice due to null object reference.Also please help me to get a way to pass the time set to the main activity.
public class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener{
public int hour,minute,id;
private AlarmManager alarmstart;
private AlarmManager alarmstop;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState){
alarmstart = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
alarmstop = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
return new TimePickerDialog(getActivity(),this, hour, minute,
DateFormat.is24HourFormat(getActivity()));
}
public void identify(int identity){
id=identity;
}
public void onTimeSet(TimePicker view, int hourOfDay, int minute){
Calendar calendar = Calendar.getInstance();
if(getActivity()!=null){
Intent start =new Intent(getActivity(),starter.class);
PendingIntent pi=PendingIntent.getService(getActivity(),0,start,0);
Intent stop =new Intent(getActivity(),stopper.class);
PendingIntent pi2=PendingIntent.getService(getActivity(),0,stop,0);
