Google Vision barcode library not found

Question

I\'m trying to use the new feature in Google Play Services (Vision) to add QR code scanning to my application. But when I run my app I get this:

I/Vision﹕ Su         


        

Answer 1

I also experienced this, the vision library could not be found on one of my test devices, although the console showed a request of the library on every start of the app, but never finished. I tested on Nexus 4,5 Motorola X2, Samsung S 2-6 and various other devices, the S5 was the only devices with the Problem. There was enough free space with over 2Gb, after hard resetting the device the scanning worked instantly as intended.
