I just upgraded to android 6 as well (i know i'm behind the times). When trying to perform a backup to my sd card (where my books are located) with moon reader pro i get this error:

Backup Failed
Attempt to invoke
virtual method 'void
java.io.outputstream.write(int)' on
a null object reference

Has there been any new ideas/workarounds that will allow backing up of my files?

Thanks for any help you can lend, Tom
