title: android ringing vibration activate/deactivate
body: <p>I can't find a way I can activate and deactivate the vibration at the time of incoming calls.</p>
  
  <p>The option in the menu --> Settings --> Sounds &amp; Display mentions - PHONE VIBRATE - vibrate phone for incoming calls...</p>
  
  <p>I want to activate and deactivate it through code (if possible).</p>
