Android - Permission denied error #60

Closed shashidhar34 closed 2 months ago

Throws permission denied error when calling SerialPort.availablePorts method on Android. I have tried adding the intent filer and meta data fields as per Android USB Host but it still throws the same error.

I had this problem in the emulator and I did not have such a problem in the real device.

For cross-platform purposes, I recommend the "usb_serial" lib for Android, which works, while the "Libserialport" doesn't work.

Have this problem as well, anyone have any updates?

eldhosekm commented 10 months ago

i also have the same problem in arm64

magnus-lpa commented 10 months ago

You could try using usb_serial plugin instead, I got that one working by using the latest commit from Github instead of the release on pub.dev. See my comment on a similar question: https://github.com/jpnurmi/flutter_libserialport/issues/76#issuecomment-1609026132
