When opening a file with an unknown extension, the mime type is empty

[dvmc]

When opening a file with an unknown extension, the mime type is empty/null, and not e.g. application/octet-stream or */*, leaving me in my case just with Intercept the Intent. When I choose one of the aforementioned mime types there, more apps are presented. Might be related to #489. Here is the intercepted intent for extension .md:

intent://media/external/file/47861#Intent;scheme=content;type=;S.real_file_path_2=%2Fstorage%2Femulated%2F0%2FNotes%2FSrpska2023Daten.md;end

It seems that when opening a file with OPEN_AS_DEFAULT, an empty mime type is submitted. I'm not too familiar with Android intents, but is this ever useful? My suggestion is deleting line 49 in Activity.kt, that way OPEN_AS_DEFAULT would yield the mime type */*. https://github.com/SimpleMobileTools/Simple-File-Manager/blob/67f519fb8988ac5e8f0f88d26c891fc40ee84828/app/src/main/kotlin/com/simplemobiletools/filemanager/pro/extensions/Activity.kt#L48-L55

just long press the given file and use Menu -> Open as

Great! That would also be a workaround for issue billthefarmer/notes#44. (EDIT: Well, it worked just once.)

However, this does not work for shortcuts.
