Imma ask again as a noob. Is it recommended or just safe enough to store it on the android wallet for mid-/long terms?
Backup backup backup. (and not on the same device! lol)
(i am assuming android wallet works like PC wallet here...) make backup of your wallet.dat file, email it to your gmail/yahoo account, if nothing else.
better yet, put it on a thumbdrive and put that into a safe.
find other ways, to put the file, safely somewhere else.
