I am trying to create a service that listens Volume key events.
Whenever the volume key presses, the service should send an sms to a number, but I can't detect volume key event.

You can use an OnKeyListener which can detect keyevents (including volume keys). You can find the keycodes here. Good Luck!

OnKeyListener for a android.os.service? does that even work. Service is a background entity. Will it monitor onKeyDown/onKeyUp? – rupinderjeet Sep 02 '16 at 11:49

1@rupinderjeet47 no, that's correct, you can't listen for them in a background service – keyser Sep 07 '16 at 20:01

As far as I understand, you can not listen for key presses directly in a service (see this question).
On an unrelated note, it is hard for me to think of a reason to do what you want aside from writing malware.
