Try changing TimePicker Hour and Minutes and resubmit AlertDialog (TimePickerDialog), they key method being ((TimePickerDialog) pickerDialog).updateTime(hh,mm);

// try adding a second reminder & alarm
addButton.performClick();

((TimePickerDialog) pickerDialog).updateTime(18, 30);

pickerOKButton.performClick();
