Code-128 with less than 6 characters not detected

I'm not quite sure if this is a bug or a matter of proper configuration, but I've been running the sample code from this github and tried it on some barcodes I generated.

In general it works very well, but when using Code-128, there seems to be a minimum number of "letters" the barcode needs to contain before the barcode reader detects it.

I've attached a screenshot visualizing the issue:

Thanks for reporting this issue. We will take a look.

Thanks WACMemphis. Do you need Code-128 to detect less than 6 chars? What's the application?

@juliangsf Yes, I would need to be able to detect any valid barcode. AFAIK, there is no minimum length requirement for Code-128.
The reason for this is that our users should be able to use all the barcodes they define. We specify which kind of barcodes they can use (Code-128, QR, EAN-8/13, etc.) and they can use any valid barcode of these types. Consequently, we'd need to be able to scan/detect them.

Detecting shorter barcodes requires making some tradeoffs that would increase the false positive rate. We may be able to mitigate this with some careful tuning, but we still have to make sure not to degrade quality for other users and that takes time.

Ok, so I'll stick to ZXing in the meantime.

1. Can we have any temporary fix or work around for this issue.

[apvasanth03]

1. We have started using "Google Vision API" for barcoding scanning.
2. Can you kindly let us know when can we expect the fix or can you provide us with any temporary fix.
3. Kindly let us know if it takes time so we can look for other library.

Unfortunately, there's no workaround for the 6 character limit.

We expect a future release will lower or remove the limit, but have no target date to announce right now.

I have a doubt that in future if this issue is fixed, do I need to update Google play sdk in my application or it will be automatically updated in user device.

[pchx-zz]

Nothing in the SDK code compiled into your application is involved in the six-character limit, and the fixed code would be rolled out automatically.

Thanks pchx.
