Android TimePickerDialog selected time not passing through to the actual Countdown Timer

Question

I've been working on getting a timepicker dialog to set my countdown timer. I have tried many ways with many different results... none of them worked right. I decided to experiment with some basic code which I will put below.

I cannot get the selected time (I called it selectedStartTime in the code below) to pass through into the actual countdown timer as startTime. I can only get the timer to work right when I use the preset startTime = 10000 (or any number). I don't want the startTime to be a set number. I need it to come from the OnTimeSetListener in the time picker box.

I will be forever grateful to anyone that can show me how to change the code so that the selected time in the dialog box is actually used in the timer.

I'm not completely sure what you're trying to achieve, just create instance of your MalibuCountDownTimer in method onTimeSet, this method will be called only when user selected time.
