I could be wrong but I think you could change part of Sub CreateDetector like this:
B4X: 
    #IF B4A
        builder.RunMethod("setBarcodeFormats", Array(0)) ' ALL_FORMATS constant, value 0
    #ELSE
        builder.RunMethod("setBarcodeFormats", Array(format))
    #End If
I think probably that way all formats for Android would be automatically supported, without having to add all the constants, even any new ones.

Maybe so, but you're currently passing it a list of formats, it seems to me, so you might as well pass zero.

Thinking about it, even though I haven't had a coffee yet ? , that's an example. At the very least there might be a spinner filled with formats.
This makes me think of a question... which as a good member of B4X.com I don't post here.

P.S. Indeed, I have to look first, perhaps the example project already does what I was thinking.

Well, I won't open a new thread because I don't need the answer, it was just a curiosity.

I would have liked to see if I could get the format, as well as the value.

Oddly that Maches variable which indicates the size of that sparse array returns 1 but if you log the "toString" method the values are more (but they don't contain the name of the format).

I thought about asking for the list of keys but... ok, it doesn't matter, it was just curiosity.

Solved :

B4X: 
    mapFormats.Initialize
    mapFormats.Put(4096, "AZTEC")
    mapFormats.Put(1, "CODE_128")
    mapFormats.Put(2, "CODE_39")
    mapFormats.Put(4, "CODE_93")
    mapFormats.Put(8, "CODABAR")
    mapFormats.Put(16, "DATA_MATRIX")
    mapFormats.Put(32, "EAN_13")
    mapFormats.Put(64, "EAN_8")
    mapFormats.Put(128, "ITF")
    mapFormats.Put(2048, "PDF417")
    mapFormats.Put(256, "QR_CODE")
    mapFormats.Put(512, "UPC_A")
    mapFormats.Put(1024, "UPC_E")
B4X: 
Dim FormatField As Object = barcode.GetField("format")
If FormatField <> Null Then
    Log(FormatField & "  " & mapFormats.Get(FormatField))
Else
    Log("format field is null")
End If
