I want to reboot targeted phone by SMS. Is it possible? How can we implement this?
For the record, it IS possible to intercept SMS messages on a stock Android phone - I've written a little app which pops up a Toast when I get a text rather than having to go in to the messages app.
It's NOT possible to perform a normal shutdown/reboot/??? without rooting the phone or being Google (at least, convinving the phone you're Google) but that would be a violation of the developer agreement.
In fact, you will find huge barriers in your way if you try to do anything to the OS or any other app - Which is usually a good thing
