I can't find much information on that tablet. Can you link me to the manufacturers web page? I just want to be sure I'm looking at the right thing. Have you verified whether any other apps off the app store can write to the removable SD card? That's what we really need to know. I'm not so sure that apps are being given write access to the external SD card on that device.
When you tried to create /mnt/external_sd/Android/data/com.zubersoft.mobilesheetspro/files, did you make sure that every folder was writable? Go ahead and use an external file browser to make them writable and then see if MobileSheetsPro is given access. If not, I'm not sure what can be done, besides me trying to switch all my code over to using that new file storage API (assuming that would even work).
