Re-check for mounted SD card

[artpi]

After switching device to Kiosk mode, we have an ability to make the device boot directly to the application (after unlocking screen), which is awesome.

However, this has a sideeffect of starting app before SD card could have mounted and shows 0 books.
It can be solved by killing the app, waiting for the card to mount and then starting app again, but that requires going out of kiosk mode.
It would be nice if when app finds 0 books, it would re-check periodically for mounted sd card again after a timeout.

Device

Moto G 2014 ( XT1068 )

Reproduction steps

1. Set up kiosk mode
2. Put audiobooks on sd card and insert into device
3. Boot the device,
4. After unlocking screen choose HomerPlayer as default launcher
5. Boot the device again
6. See that Homer Player shows no audiobooks even though there are some on sd card
7. Kill Homer Player ( :( )
8. Launch again
9. See that it sees books

Thank you for the detailed bug report.

Can you test one thing for me?

1. Boot the device with Homer Player in kiosk mode, with books on SD card.
2. There will be 0 books.
3. Remove the SD card.
4. Inserd the SD card again.
5. Wait 15-20 seconds.

I wonder if the books will be detected after these steps. Thanks in advance!

I am trying to arrange the proper test, but my grandma does not want me to touch her reader before she finishes the books she is reading :)
Thank you so much for this project, it brings her a lot of joy!
I will write again when she lets me experiment.

The recent version rescans files in search of audiobooks 10s after the first scan if there was no content (and then every time the UI is started).
Please let me know if this helps with the problem.
