Always ask permission to use USB port #49

Closed dariocavada closed 11 months ago

dariocavada commented 3 years ago

Every time I open the program it asks me for authorization to use the USB port every time.

Is it possible to remove the dialog once permissions have been granted? Or somehow add the permissions so that the dialog doesn't open?

altera2015 commented 3 years ago

Not sure what is going on this was certainly not the behavior intended ( nor observed ). Unfortunately I don't have a USB Serial dongle at hand at the moment. Maybe someone with hardware at hand can contribute?

It's an Android Problem...

I've tried all possible manifest configurations without any success.

on a Samsung S8 with Android 9, I don't have this issue. I've just added an intent filter as per the repo README. Once I give the permission after connecting my device, it doesn't pop up anymore.

What worked for me is to create the intent as explained above, install the app with the device disconnected and connect the device. Android will ask if you want to open the application when the device is connected.

If you grant the permission when the application is already running and trying to access the device, it only will work until the next reboot.

Today a user reported that one tablet is asking for permission after every reboot, it does not ask when the device is connected. I plan to remove the permission, reboot and follow the procedure.

Closing since this is an android issue.
