Android Question Java Object and NFC-V

[akinnovation]

Hi,
I'm try to get the AFI from an Iso15693 tag using the NFC library 2.0.
I have seen that this field is into the java object returned from the getTag method.

  TagTech.Initialize("TagTech", "android.nfc.tech.NfcV" , si)
            Dim jo As JavaObject = TagTech
       
            Dim tagNfc As JavaObject = jo.RunMethod("getTag", Null)

if I watch the tagNfc variable in debugger I see that the value I wish is:
mtagNfc.mTechExtras[0].mMap[1]
How I can read this value ?
I have try with tagNfc.getfield, with .getfieldjo, but the return is always an error
with " mtagNfc.mTechExtras[0].mMap[1] doesn't exist".
Please help me.

Best regards
marco

Is AFI the same as DSF ID ?

I'm sorry, but no.

Can you post a screenshot of the debug window which shows the value?

This is the screenshot. I need to read the 0x30 value -mArray(1)-

Try this:

Log(GetType(jo))
Log(jo.RunMethod("getResponseFlags", Null))

OK EREL, Great !

jo.RunMethod("getResponseFlags") return exactly the iso15693 AFI byte.

Many Thanks
