Getting an error after trying to open TimePickerDialog

//When user clicks "choose time"
    public void setTime(View view)    {
        DateTime dateTime = new DateTime().now();
        Context context = getApplicationContext();
        new TimePickerDialog(context,  onTimeSetListener, dateTime.getHourOfDay(), dateTime.getMinuteOfDay(), true).show();
    }

    TimePickerDialog.OnTimeSetListener onTimeSetListener=new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {


        }
    };

I get an error after the user clicks on the "choose time" button, which should use this method. I know that the onTimeSetListener method is empty, but I don't think it's related to the crash..

This is the error I get after trying to open it up:
