title: Activate Android with touch instead of power button
body: <p>We've got a tablet application for which we want to screen to timeout after a certain period, but would like the user to re-enable it by touching the screen instead of the 'power'-button on the side of the device.</p>
  
  <p>What's the best approach (battery performance) to this?</p>
  
  <ol>
  <li>Using a Partial Wake Lock (will the screen react?)</li>
  <li>Disable the screen in some way, but keep everything (including touch response) working?</li>
  <li>Other?</li>
  </ol>
  
  <p>Any suggestions on this?</p>
