Ask for storage permissions on Marshmallow

[dgw]

After upgrading my device from Android 5.1.1 to Android 6.0.1, SIF Train began crashing immediately on startup.

When I went into its App Info screen and manually turned on its ability to access the device storage, it worked again.

This seems to be the only thing keeping the app from working flawlessly on Marshmallow.

As of Android M, permissions for storage read/write are considered 'dangerous' and have to be explicitly enabled by the user. Sadly, the library used in this project doesn't request the missing permissions on demand, which is why there's nothing much I can do. Perhaps I could add a check on the splash screen and display a message if the permissions are not present.

I assume you mean libgdx? I'm presently trolling through the issue archive over there hoping to find some mention of this problem. You might not have to do anything about it except update libgdx when it's fixed, who knows?
