Selfi Stick Shutter Button, How Make?

[Nehmo Sergheyev]

I want to use an Android Phone with camera to take pic's, but I want to use a remote "shutter" button, like on a 1m cord (or wireless). Actually, I want to fix the phone/camera on a selfi stick and have the trigger, the shutter button, on the handle end of the stick. Ideally, the button would be electrical and plug into the mini-usb port of the phone. A mechanical one would be workable, though. A bluetooth method would work too.
So, is there any way of using a remote shutter button on an Android 4.0.4 phone?
