Android Question Local hotspot error

[Hamied Abou Hulaikah]

Hi,
I got this error when using local hotspot example:

UID 10392 does not have Coarse/Fine Location permission
'the number 10392 is changed every run to another number
'I granted fine location without success

error thrown on android 9 and android 12 devices.

 

[Erel]

Can you post the full stack trace from the logs?

Have you made any changes to the example? The location permission is requested and checked.

Have you made any changes to the example?

No

The location permission is requested and checked

Yes

Can you post the full stack trace from the logs?

Tested on 3 devices:
I see error on android 9 and 11 is the same: location mode is not enabled, but location permission is granted!
And in Android 12 the error as above.
In B4A IDE, I don't see dangerous location permission listed in permission list in log tab. why!!!

[Erel]

Why write the logs like this???

Looks like location services are disabled on the first two devices. Enable them in the settings app.

About the third device - uninstall the app and install again. Do you see the location permission request?

sorry

Enable them in the settings app.

Yes, it is enabled from app settings

Do you see the location permission request?

Yes, requested and granted.
Also in app settings is granted.

FWIW, I've just tested it with an Android 11 device and it works perfectly.
