Android billing - where in the app flow is the best way to verify that the user is subscribed or not? -

-

i have application able user subscribe.

but not best way manage subscription inside app. since user can unsubscribe outside app, need check status of subscription every time open app? or slow down app flow?

or there better way that? thanks!

all of apis asynchronous. shouldn't slow application down if ask verify application loads , response when it's ready. far know, should tell once subscription status changes, there's no need poll it. user can fool disconnecting internet connection while using app, next time connects, should pick on that.

if aren't already, i'd suggest use androidbillinglibrary. it's pretty easy use , abstracts away of difficulties. should enough basic cases. make sure apply this patch or version applied.
