LrkFM 1.6.4: App crashes as it tries to go beyond the device root folder

Project Information

• Repository:
  https://github.com/lfuelling/lrkFM
• Project Name: LrkFM
• Publisher: Lukas Fülling

Expected behavior

Taking the directory back to a parent folder making use of the arrow cap icon at the bottom right, when the device root folder is reached it isn't suppose to go any further. There shouldn't be any more activity to perform beyond that.

Actual behavior

On going back the directory levels and reaching the root folder '/', the application crashes when the icon is tapped again.

How to reproduce

1. On the app main page showing the files, make use of the arrow cap icon at the bottom right to go back the directory levels till the root folder is reached.
2. You can check the current folder by looking at the top of the side menu.
3. Try to go back again using that icon and app will crash.
