Android Question [B4XPages] Barcode Reader - internet required?

[Mark Stuart]

With Erel's BARCODE READER app using the Camera library, I see it has this reference:
#AdditionalJar: com.google.android.gmslay-services-vision

And in the B4XMainPage - CreateDetector function it references what looks like more internet references:

builder.InitializeNewInstance("com/google/android/gms/vision/barcode/BarcodeDetector.Builder".Replace("/", "."), Array(ctxt))
Dim barcodeClass As String = "com/google/android/gms/vision/barcode/Barcode".Replace("/", ".")

So I'm wondering if the code is requiring an internet connection while being used?
The "List Permissions" button lists: android.permission.INTERNET

My app solution will not have internet connection while being used to scan barcodes.

Appreciate a response.

Regards,

I think it needs an initial internet connection to download some dependencies. Once downloaded the internet connection should no longer be required

1D and 2D Barcode Scanner with ZXING - another Barcode Scanner that is 100% embedded in B4A

The attached project wraps the ZXING part of this Github project. I have not tested all the barcode formats but it should scan the following types: BarcodeFormat.UPC_A BarcodeFormat.UPC_E BarcodeFormat.EAN_13 BarcodeFormat.EAN_8 BarcodeFormat.RSS_14 BarcodeFormat.CODE_39 BarcodeFormat.CODE_93...
