usage:

(1) Press the Make Folder button to make a working dir in /storage/emulated/0/000dateset/. All images captured will be put into 000dateset folder.

(2) Adjust 3 seekbars (ISO, shortest exposure time, longest exposure time.

(3) Fix the device, press the BIG burst button to commit burst. Now the program will play a music as a reminder that you shoud HAND OFF the cam, and the program will sleep for a few seconds, waiting for the vibration of tripod to decrease.
