B4X:

If File.Exists(File.DirInternal, "/Saved") = False Then
File.MakeDir (File.DirInternal, "/Saved")
End If
If File.Exists(File.DirInternal, "/Saved/LowJoe") = False Then
File.MakeDir (File.DirInternal, "/Saved/LowJoe")
End If

B4X:

If File.Exists(File.DirInternal & "/Saved/LowJoe", "LowJoe_Stats.txt") Then
List1 = File.ReadList(File.DirInternal & "/Saved/LowJoe", "LowJoe_Stats.txt")

If you are targeting SDK API 23 or above, you will need to use the new runtime permissions (specifically the RuntimePermissions.GetSafeDirDefaultExternal("") method):

Also, you probably should be using the RandomAccessFile library and the new(ish) WriteB4XObject/ReadB4XObject methods which are more robust than read/writelist and in addition support custom types.

Small clarification, you don't need to do anything special for your app to work on all Android versions including Android 7. Runtime permissions are only relevant if you decide to set android:targetSdkVersion to 23+.
