Android Question Maximum QR/BarCodes can be read at same time?

[Angel Garcia]

Hello,
I have a maybe silly question.
I have implemented this reader : https://www.b4x.com/android/forum/threads/b4x-b4xpages-barcode-reader.120417/ on my App, but i have noticed it can read at same time a maximum of 10 QRCodes, so the question is if there is a maximum of barcodes the reader can read at same time?. I have been looking at this documentation with no luck.

I have been looking for the "size" method on documentation but, i cant find any reference.

Dim Matches As Int = SparseArray.RunMethod("size", Null)

Any help would be appreciated.
Regards.
Ángel

That depends on your camera and phone. All qr codes on screen could be ready "at same time". My best records is 18 qr codes in one second then it keeps on after one second.

The camera preview will get all qr code visible then returns. The runmethod ("size") will tell you how many detected.

Hello hung,
Thanks, I guess i'll have to try with different phones to analyze behavior.
