title: Android: Querying contacts saved on the device by other users
body: <p>In multi-user android device, How to query contacts saved by another user from currently active user.</p>
  
  <p>I want to query contacts database from <strong>System UI</strong> Process. Since <strong>System UI</strong> runs in owner mode, it can't access the contacts of another user even if the owner is not an active user. Is there any way to achieve this?</p>
  
  <p>I searched thoroughly about this on the net but could not find any such concept.</p>
