osu!lazer not loading rulesets (Android)

[X4X5]

Describe the bug: I don't really know how serious this is, mainly because Lazer ran fine with few lag spikes, but whenever I open Lazer, I keep getting a notification saying, "Could not load rulesets from directory."

Screenshots or videos showing encountered issue:

osu!lazer version: 2019.1011.0

Logs:
runtime.log

[bdach]

This is due to Environment.CurrentDirectory pointing to the filesystem root / on Android devices, and the OS quite rightly complaining about not having permissions to access it, here:

osu/osu.Game/Rulesets/RulesetStore.cs

Line 133 in 8d6851c

string[] files = Directory.GetFiles(Environment.CurrentDirectory, $"{ruleset_library_prefix}.*.dll");

It's not fatal, but we should probably consider not even trying to load from fs on mobile/if permissions are missing.

[X4X5]

Meaning there are permission I have to manually give Lazer access to?

[bdach]

No, this is not a permission-granting issue, we shouldn't even go looking there on Android. / is not going to be accessible on any unrooted device.

[bdach]

Seems to not be completely fixed, as I've seen a log on 2019.1021.0 where this persisted (see #6605)

/ root of android is still accessible on lollipop to marshmallow version (and i think, nought too..), and but still, lazer should point access direct to it's data folder,

private location /data/data/sh.ppy.osulazer/

or

public {INTERNAL_OR_EXTERNAL_MEMORY}/Android/data/sh.ppy.osulazer/

not the root "/" to find such file cause on newer versions of android, access to root folder is impossible

[X4X5]

If it's a root folder, don't you have to root the device? And my phone isn't like one of the nicer phones; it's a Samsung Galaxy J3 V, so I wonder if just the type of phone it is has something to do with the issue, idk.

[dragonGod97677]

Rooting not necessarily required, it's maybe lazer side problem, not the phone it self. Just wait X4X5 until they fixed it

[X4X5]

Got it

[smoogipoo]

A fix was attempted in #6510 but it seems like it didn't work, since this is still occurring. It's likely that the reason is Environment.CurrentDirectory being reset in https://github.com/ppy/osu-framework/blob/94bfa3473f15824180ea4fcc3f3a3e716c0fc735/osu.Framework/Platform/GameHost.cs#L495

[sentry-io]

Sentry issue: OSU-LAZER-38P

[X4X5]

So is there anyway that this can go about getting fixed?

[dragonGod97677]

Same as #7282

[bdach]

@dragonGod97677 As far as I'm aware this error shouldn't be fatal or cause hangs, so it's not a duplicate of the issue you mention.

[dragonGod97677]

Oh ok...

This also happens on Mii 9, it does find the rulesets but cannot load them.

[bdach]

@Flutterish that is not the exact same error and as such does not fall within the scope of this issue.
