title: How to install the barcode scanning library without a google account?
body: <p>I would like to install the android-vision portion of google play services on devices that are not allowed to have a google account signed in. Traditionally, the android-vision library is downloaded through the play store as an update to google play services.</p>
  
  <p>According to <a href="https://developers.google.com/android/reference/packages" rel="noreferrer">this</a>, the package name should be com.google.android.gms.vision.barcode. I used adb to list all packages installed on my rooted nexus device that has the barcode scanning library downloaded and the package was not in the list. I was hoping to pull the package itself and then distribute it.</p>
  
  <p>Thank you for your time and effort.</p>
