I want to reboot targeted phone by SMS. Is it possible? How can we implement this?
Your problem has two core parts. Can you reboot the phone programatically? Can you write a program to intercept incoming SMS? If you answered YES to both of your question, it is possible to do this.
I am not a Android developer but i think this should be quite possible.
take a look @ Android SMS intercept without notification icon or WAP-PUSH messages and http://mobiforge.com/developing/story/sms-messaging-android
I think BroadcastReceiver is the one you are looking for.
I have no idea whether you can programatically reset the android phone using java... Someone else might answer you about that
EDIT: I guess according to the link Bill has posted, 3rd party applications are not permitted to do a reset
