title: Can't resolve getSystemService(FINGERPRINT_SERVICE)
body: <p>Very strange issue faced. The following code </p>
  
  <pre><code>fingerprintManager = (FingerprintManager) mContext.getSystemService(Context.FINGERPRINT_SERVICE);
  </code></pre>
  
  <p>underlines in red color the Context.FINGERPRINT_SERVICE and says: "must be one of following... " and prints me all the possible system services, where FINGERPRINT is absent. But if i go into sources of Context class I can see the FINGERPRINT_SERVICE constant present. 
  Permission included in manifest.
  Build tools is 23.0.1.
  Worked in another project with the same studio and api level. What is wrong ?</p>
