title: FaceDetectorHandle﹕ Native face detector not yet available. Reverting to no-op detection
body: <p>I'm trying to incorporate the Google Play Services 7.8 Face API in my app, but every time I try to detect faces it gives me the error:</p>
  
  <blockquote>
    <p>FaceDetectorHandle﹕ Native face detector not yet available.  Reverting to no-op detection</p>
  </blockquote>
  
  <p>According to the bottom of the post <a href="http://android-er.blogspot.com/2015/08/face-detection-with-google-play.html" rel="nofollow">Android-er Face Detection</a>, this problem occurs on devices running Lollipop or later. Specifically, they said it works on a "RedMi 2, running Android 4.4.4 with Google Play services version 7.8.99 installed, but not on a Nexus 7 2012 (WITHOUT front camera) running Android 5.1.1, with the same Google Play services version 7.8.99 installed." It also doesn't work on my OnePlus One running 5.0.2. Does anyone know the cause or fix? Will it eventually install the library and work?</p>
  
  <p>Edit:
  Here are some logs. I just copied logs warning and higher around the time that the face detector was used, so it might not all be relevant.</p>
