title: SignalStrength has no method getRsrq in api 25
body: <p>When I use <code>api 25</code> as my compile sdk some methods from class <code>SignalStrength</code> are getting marked as hidden. 
  <a href="https://i.stack.imgur.com/012aX.png" rel="nofollow noreferrer">Example</a></p>
  
  <p>How to deal with it if I need to use <code>SignalStrength.getLteRsrp()</code> but it is hidden?</p>
