title: How can I timeout my application?
body: <p>I have a requirement where i need to show a pin entry screen to the user after a time out value which the user will select in the application ( for example he selects time out ) . 
  What i plan to do is note down the current time on deactivated event . In activated event calclate the time difference + time out set in the mobile. If difference is more than time out show the pin screen else dont show. </p>
  
  <p>But my question is how do we get the "Screen times out after" value which is an option set in the mobile settings screen </p>
