    Nice! Is there an iOS implementation? And to push the luck- Xamarin Forms abstraction?

    I see that there is a project on Github for firebase-dispatcher-ios, but it doesn't seem like anything is happening (going to happen?) with that project. So, I'd expect that this will be Xamarin.Android for now.

    how about the interaction with the Doze mode? same problems that we can find using GcmService or it can be more flexible? I'm try to find a way to avoid the fight with the Doze mode... :-(

    @andrekiba : Not sure 100% sure I get what you mean by "interaction with Doze" (although I think I have an idea): When you schedule a job with FJD, you're ultimately just making a request to run some work. FJD will try to honour your request as best as it can, but it's possible that the operating system (i.e. Doze mode) may "devalue" some of the criteria for that request.

    A good way to think of FJD: "Please run this work at some point, and here is a guideline on when".

    I hope that answers your question.

    yes :smile: with GcmTaskService you can setup a task that tries to follow a schedule...but in Doze mode background tasks are deferred (and executed only during active windows) and so the only why to make a sort of “sync in background” when the device is inactive is to move to push notifications. Following your answer I think the same thing is maybe true also for FJD... :-( ...not so good...

    You might could try off sending a high priority Firebase Cloud Message. In theory, that should wake the device for a few minutes. Exercise with discretion however.
