Google now forces apps to use SAF with specific permission for each file.
If it is lost by SD card (or OEM), the apps can do nothing, but ask it again.
(for security, Google allows user only to initiate the process)
Something strange seems to happen in your device or workflow,
as I cannot reproduce it.
Or you took out the card and open the app,
or you connected the phone with pc and open the app?
(where the card was used by the pc)
And exactly THIS i miss.
I never noticed such a message - after restart of the smartphone the app opened online map without any notification.
How does the notification look like? (Then I will have another trial wether I will see it.)
You can open a map file, close the app, rename the map file and open the app again.
A toast message will appear at the bottom of the screen, informing of invalid map file
and the online map will be activated.
…agree, offline/online maps info should be visible always, my old Huawai Phone lost many times the offline
maps, ans switch to online maps. This should be never happen in Switzerland and Roaming is on. The cost can be massive…
sorry the Huawai battery management is kill my Offline map conection (internal storage) always during App is closed (screen switch off), and there is no warning. If you aware with problems like that you can configer the battery management, thats work.
May these INFO can be more visible:
Maps are huge. So SD-card is a good place if your device is short on memory
If user had selected offline map, and than some time later (for whatever reason) offline map becomes inaccessible the app switches back to online maps.
Although there is a short info, the switching to online map is done automatically.
Wouldn’t it be better to ask the user for confirmation before doing the switch to online map?
