detector.isOperational() always false on android

Question

I\'m using the new google plays service: Barcode detector, for this porposue I\'m following this tutorial : https://search-codelabs.appspot.com/cod

Answer 1

Sometimes detector dependencies are downloaded when the app runs for the first time and not when the app installs. I too faced the same issue, the problem is either your network connection is weak or you don't have enough storage for download say 10% of the total space though it does not take that much space but downloads from Google Play Services does require good amount of storage and don't forget to clear cache(Simple check try to update any application from playstore). Refer this Github thread for more information.
