Android Question B4xpages barcode reader example problem.

[calloatti]

I am testing the example barcode reader project from https://www.b4x.com/android/forum/threads/b4x-b4xpages-barcode-reader.120417/

It works fine in 2 devices, but on a cheap tablet it fails to work with the message "Failed to create detector" (I guess its the toast in the Sub CreateDetector (Codes As List))

This is the full debug log:

Any hints as to what is wrong with this particular Android 10 tablet?

Maybe the problem is that the android vision api is being deprecated?

The Mobile Vision API is now a part of ML Kit. We strongly encourage you to try it out, as it comes with new capabilities like on-device image labeling! Also, note that we ultimately plan to wind down the Mobile Vision API, with all new on-device ML capabilities released via ML Kit.

Maybe an updated example using this ML Kit could be posted?

Is anyone else seeing my posts? Just checking.

Have you tried with other model of phone? What model exactly you are using?

It works fine in 2 devices, but on a cheap tablet

This sound like a hardware issue. It may also due to the error “mapper 3.x is not supported”

Try download some barcode reader apps from play store and see if the device can function?
