title: when is BLUETOOTH_ADMIN android permission required
body: <p>I read here <a href="http://developer.android.com/guide/topics/connectivity/bluetooth.html" rel="noreferrer">http://developer.android.com/guide/topics/connectivity/bluetooth.html</a> that :</p>
  <blockquote>
  <p>If you want your app to initiate device discovery or manipulate Bluetooth settings, you must also declare the BLUETOOTH_ADMIN permission</p>
  </blockquote>
  <p>What I think is that methods like</p>
  <blockquote>
  <p>cancelDiscovery()</p>
  <p>isDiscovering()</p>
  <p>startDiscovery()</p>
  </blockquote>
  <p>requires the BLUETOOTH_ADMIN permission.</p>
  <p>Are there any other methods that requires this permission?</p>
