How does Android's WifiManager new 'EXTRA_RESULTS_UPDATED' work?
<p>I noticed a new boolean extra <a href="http://developer.android.com/reference/android/net/wifi/WifiManager.html#EXTRA_RESULTS_UPDATED" rel="nofollow">EXTRA_RESULTS_UPDATED</a> in the WifiManager class.</p>

<p>The documentation, however, is somewhat minimal:</p>

<blockquote>
  <p>Lookup key for a boolean representing the result of previous startScan() operation, reported with SCAN_RESULTS_AVAILABLE_ACTION.</p>
</blockquote>

<p>So how does this work, exactly? Is is only true when my app requested a startScan() and the scan is completed? Is it true whenever some app, including mine, called it? Or is it always true whenever a scan has completed regardless of startScan() was called by an app, system, etc?</p>
