Hello! In my app i need to read tagid via NFC.
But when i run APK (or run via Companion) and put NFC tag behind device, i got question from Android - which app i want to run to read tag. And it’s happens on main screen and other screens. It impossible to read tag.
I have Android 9 on Galaxy Fold, same problem on Galaxy S9. What i do wrong?
Of course i put Near Field component on Screen1 and place logical block “whean NFC.tag read”…
With Galaxy S5 and Galaxy S7 I tested, I have the same problem.
Update july 2020: I had the same problem but formatting a NFC, with NDEF format, solves the problem.
Do not test in companion but as apk. Appinventor warns for this behavior.
IMPORTANT: Applications built with the NFC component will not respond to tags while in live development mode. To test your application, you must build your app and download the APK to your phone .
Yeah, i am, but this example utilize message written to tag not its ID. In event block when Near_Field.TagRead are blocks named tag ID and massage. Massage works but tag ID show nothing.
Hi,
so I am having the same issues, has anyone found out how to suppress these Android Pop ups?
I made a little Test apk but it couldn’t solve the problem.
Hi,
sadly no.
I have put my project on hold until this is fixed.
Also semmes kind of funny to me that this topic has gone under the radar for this long now.
It is not a bug, it works but you have to take every step in the right order, in the right environment. For instance use a NDEF pre-formatted tag otherwise it fails.
NFC failure is not due to Appinventor nor Kodular.
If you want you can get paid support, to find out what step fails.
