Android app to silent your phone when faced down

This is my 3rd app. Everyone knows I am bad at XML and designing, so this new app is devoid of any user interface. But before you exit, hey its pretty useful. The app doesn't need to be opened every time. Just install the app, and open it once. Now you are good to go.

Uses(a few) :
-1. When you enter a meeting you simply just put your device face down, and when you exit the meet you hold your phone in a state that its not face down and now you are reverted to your previous state. No messing with sound settings. -

-2.Put your phone faced down and incoming call is silenced.-


This is my first productive app, and I beg you for your invaluable feedbacks in comment
