External sdcard detection on Sony Xperia Compact F5321 @ 8.0.0 #3558

SD Maid can match the SAF permission if manually granted, but can't related it to the external card.

The system exposes only exposes EXTERNAL_STORAGE=/sdcard.

And that's not enough for SD Maid to understand the relation.

The system also doesn't expose the external sdcard via API: 

D/SdcardModule: getExternalCacheDirs(): {/storage/emulated/0/Android/data/eu.thedarken.sdm/cache}
d4rken commented 4 years ago

Adding /sdcard is too vague to match against /storage/4E39-DCD4 as /sdcard is present on any device.

Matching would need to be reversed, instead of:

we'd need to

Basically include the list of mapped permissions as source for storage detection, that would allow users on any device where SD Maid doesn't detect external storage to manually add it.
