Since push.com services will stop in the near future, this leaves us developers without the possibility to receive push messages in B4A apps. OneSignal seems to be 'the' new reference on the market, but a library for B4A is currently missing.
@Erel, the ability to receive push messages seems to be pretty trivial for a B4A app, no?
Lots of solutions in that list use the parse.com library, which was easy to use. And parse.com shuts down. See Parse service is shutting down: http://blog.parse.com/announcements/moving-on/
I understand the feature request. However saying: "this leaves us developers without the possibility to receive push messages in B4A apps" is far from being true.
