How big is the download for my users if my app requires the 2015 Android Vision API?
<p>I am interested in adding face detection to my app (com.google.android.gms.vision.face the Google Play services 7.8 version as described <a href="http://android-developers.blogspot.co.uk/2015/08/face-detection-in-google-play-services.html" rel="nofollow">here</a> <a href="https://developers.google.com/vision/?utm_campaign=facedetection-815&amp;utm_source=dac&amp;utm_medium=blog" rel="nofollow">here</a> and <a href="https://developers.google.com/android/reference/com/google/android/gms/vision/package-summary" rel="nofollow">here</a>) </p>

<p>But in the documentation it says 'Adding the vision functionality dependency to your project's AndroidManifest.xml will indicate to the installer that it should download the dependency on app install time'</p>

<p>Its very important to me that my App size should be small and not require a huge  download- so does anyone know how big the 'dependency' for com.google.android.gms.vision.face will be and how much it will add to my download for users that don't already have it?</p>

<p>Also do people know if iOS works the same way?</p>
