• Error Log

  LOG  WifiP2P initialized
  LOG  Permissions granted never_ask_again never_ask_again granted
  LOG  {"code": 0, "message": "Operation failed due to an internal error."}
  LOG  {"code": 0, "message": "Operation failed due to an internal error."}

Looks like ACCESS_COARSE_LOCATION and ACCESS_BACKGROUND_LOCATION is granted, but others are never_ask_again

Adb Logcat

Hello 👋

From the logs:

WifiPermissionsUtil: UID 10413 has no location permission

I think you need to grant permissions properly 🤔

[BRAVO68WEB]

I gave it BTW @kirillzyusko

[kirillzyusko]

@BRAVO68WEB but according to logs the service doesn't have a permission and because of that it can not be started 🤷‍♂️

[BRAVO68WEB]

But my ACCESS_FINE_LOCATION says granted

[kirillzyusko]

@BRAVO68WEB my expectation is that never_ask_again !== granted. Again, I would trust logcat output - if it's saying that location permission is not granted, then it means it's not granted and you need to figure out what's going wrong there...

[BRAVO68WEB]

Any hints what and where to check?

My background in not from Android but Web and DevOps

@BRAVO68WEB try to grant proper location permission. Can't give more exact direction - I don't have real Android 10 device.The only one way here is trial and error. Maybe try to use react-native-permission library 🤷‍♂️
