I have a problem with ac2dm. I have implemented it on my apps and it
worked.
All users that have lauched my apps before 29 of september, I can send
them a push with their devicetoken I have in my database (return
id=0:1323957028222391%279cbdef00000030 for example). Since, with all
new lauch of the app (and then, all new devicetoken), when I send a
push with the same method it return Error=InvalidRegistration.
Device token changes correctly when I launch the app but I can't send
any push. I don't publish any update of the app...
Thanks
check if you have the correct developers email id in the app. it should be the same email id as the one which signed up for c2dm.
I have the correct developer email. And I can send push to users that
have launched my app before 1st of october (I've made others tests and
it's definitively since the 1st of october that all device token I
push on doesn't work.)
