I made this tool for practice purpose and my own use.
※This tool is not usb driver.Please install usb driver if you can''t connect device and pc.Usually you can download it from device vendor''s site.
I got inquiry,so add notes.
At first, I try to make this tool as widget which can toggle USB Debug settings directly if you touch it.But I don''t adapt it because it''s not recommended way from Android 1.5. So I choose normal Activity which just finishes after calling Settings UI.
