When is Android's backup service not available? -

-

the document here states that:

'data backup not guaranteed available on android-powered devices'

are there examples of when backup service not available on device? backup service guaranteed there if user has installed app via google play (i.e. have google account)?

thanks

well, 1 thing, requires api level 8 (android 2.2) or greater, 6% of devices google play can't use it. otherwise, think it's safe assumption vast majority of devices 2.2+ , google play have access it.
