title: Android for Work ANDROID_ID is returning NULL
body: <p>I'm using the following code to get the device id:</p>
  
  <pre><code>String androidID = Settings.Secure.getString(getActivity().getContentResolver(), Settings.Secure.ANDROID_ID);
  </code></pre>
  
  <p>According to the doc <a href="http://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID" rel="nofollow">here</a>, ANDROID_ID value is unique to each user. What I found is that the above string "androidID" is null when I tested my app under a managed profile (using BasicManagedProfile sample).</p>
  
  <p>I'm assuming Android for Work is built on multi-user implementation. Why ANDROID_ID value is NULL here? </p>
  
  <p><strong>EDIT:</strong> Is there any other way to get device id from the work profile?</p>
