Android Oreo (8.0)

Affected device model

Xperia XZ

How did you install the app?

F-Droid / IzzyOnDroid

Steps to reproduce the bug

Install the application for the first time on a device and run it.

Expected behavior

It should just request storage permission as it's needed for the application to operate. Nothing triggering this exception should be done if it doesn't have the requested permission.
That aside, does it even make sense for a file manager to allow the user to interact with it before providing the needed permission? It doesn't seems like a file manager can have any use if it can't access storage, does it?

Actual behavior

Application triggers an exception in a popup related to the storage permission, even on the first time the application is launched and before the user could do anything to give the application the requested permission. See screenshot below.

Note that as I wanted to reproduce the issue for the screenshot, rather than uninstalling the application to reinstall it, I just wiped data and removed storage permission but it didn't act as the first launch curiously: it didn't request the storage permission again.
