Hi:

I’m not in my computer now, but you’re trying to read some qr code not supported.
Read this, in some place in the app you have to set ALL_FORMATS if ypu don’t know the format you’re reading

Check this post. If with that list in the array you’re not success, then just put ALL_FORMATS

EDITED: See post 8 in the thread, I can’t set the link

hi - thanks for the input ALL_FORMATS works
Change code in B4XPage_Created( ): 
CreateDetector (Array("CODE_128", "CODE_93", "QR_CODE"))

'Changed to
CreateDetector (Array("ALL_FORMATS"))

I am looking at QR codes so I tried
B4XPage_Created(): 
CreateDetector (Array("QR_CODE"))

And that also worked, but what I don't understand is the original code supported 3 formats including "QR_CODE" but for some reason it did not work.

Anyway, once again thanks for your help
