I dont think you can use NFC witout an intent. If NFC is switched off the it wont read cards (obviously) but when on it only works with an intent.

yes, thank you Joham

now i got it to work.
but maybe because my app is very complex (many views etc not just one) i manage to read several times perfectly and then with no reason the app crashed with this error message in the log

this error also happens with your sample app

after that nothing will make it work only reset to the phone sometimes multiple times
any ideas?

there are 2 errors each from a different device

this is from a phone with android 9
