When I use the barcode app in Android it doesn’t show results. I try going to web search or product search after scanning but nothing appears. Where do I get information?
get another barcode app
Problem is not in the app but barcode apps obtain the details through the codes via Google product/shopping/web search yielding no links for not a single code
Try to google just the last 5-7 digits of the barcode
Use a better scanner for scanning the bar codes. Most of the time, the information is based on the information stored about the item in it's database/ So it will be hard to get info for items that are not generic.
Google web search yields no results for any code scanned
I guess you are trying to read some bar-codes which have information that''s not in the apps DB.
Download another app i guess.
