BluetoothLE Error on Android 9 - Error 3300: Error 9101 in Extension BluetoothLE: Expected device index between 1 and 0

[Hans Dampf]

Hello Forum, 

I have a weird problem with an AI2 application. I was using this for some time on Anroid 5, 6, 7 and now installed it on Android 9 (Samsung Galaxy XCover 4, SM-G390F) where it stopped working.

Upon starting (not quite correct, check the edit below) the application I can see this error on screen:

"Error 3300: Error 9101 in Extension BluetoothLE: Expected device index between 1 and 0"

I was browsing the web for an answer or at least a hint, but nothing so far. Does anyone have an idee?

Where I could try fiddling around etc?

Thanks!

edit:

I wanted to add some information.

if the BLE scan does not find any devices, I set the listpicker item to a string like "Nothing found, please go back and try again in some time".

The above error does only appear, if I click my phones back button, so I think it has something to do with not picking anything in the listpicker.

As this was not a problem in Android below 9, has something changed there? Should I try modifying the app to disable BLE or sth like that if the listpicker is left without picking (when listpicker.lostfocus(), for example)?

Which version of the BLE extension are you using?

Cheers, Ghica.

Post your Downloaded Blocks Image, in case it's

a logic error.
