update: well I'm stuck.
I installed astro on the Kobo tablet, but i cant find where Moon reader & various other apps are stored, in order to try the backup process. I do have other paid-for apps on here that were bought from aamzon that I can test with, if i can find them - like the birds of britain app.

but I can't figure out the porcess for locating and backing up an app - can you help please
am I missing some obvious menu in the app for making backups, all I seem to have is the file explorer facilities, which presupposes an extensive knowledge of android folder structures & naming conventions ?

UPDATE :
duh - after a trip to developer website - I did not think of swiping left to right!

so I found the backup option, I backed up the birds of britain app that I bought from amazon OK, though I can't now see where it's put that backup file , so If i were wanting to copy it say to my dropbox or google drive I dont' see how, still.

I did see that the moon reader pro app was labelled "locked" so it's not going to back up any paid for app from google store - fair enough.

update 2: Ok I found the backup folder, with more help from google. I can see the backed up birds app.

so is this how protection works: the paid for amazon apps only run on a tablet registered to the account from which they were purchased ? but they will tun on and device if its compatible & so registered. whereas the google store apps have to be downloaded from play store ( which implies ytou are looged in) & they are then locked byt the android OS on that device.
