The error you saw is something I display, so it would be the same if the OS was 4.4.2 or 5. Based on your description, this may have been the same kind of problem. If your device was running critically low on memory, I may have tried to force resources to be cleared. I'll have to rework some of that code if that's the case, but I would be very curious to see how much RAM was available on your device when this happened. If you had a large amount of background apps or tasks running (or even just one or two that use a lot of RAM like MobileSheetsPro does), this may have contributed to the problem.

As for the other issues you described, there is a little bit of a problem when using an external SD card with Android 4.4 or higher - MS Pro will not be able to write to it. That means you cannot restore a backup to an external SD card unless you use the application data directory for MS Pro: <external SD card path>/Android/data/com.zubersoft.mobilesheetspro/files. When MobileSheetsPro runs into this situation, it will revert back to the internal SD card so that the backup can proceed. Other posts have been made about this to provide better options for handling this situation and to provide more information to the user. As a side note, I'm not sure if you selected "Original File Locations" as the destination on the restore dialog. If you did not, then MobileSheetsPro wouldn't have even tried to write to the external SD card.

I think your case, if you want to manage your own files, you would be better off just backing up the MobileSheetsPro database file yourself, and backing up your external SD card files when needed. If I can overcome the external SD card limitations for Android 5.0, then this will all be supported through backup/restore again. Unfortunately, as mentioned in other posts, I have a fair amount of work to do there as it turned out to be very difficult.
