Does anyone know of a good lightweight reactive library? RxJava is simply to bulky imo.

Android has its own reactivity — Broadcasts and BroadcastReceivers. Also, as my collegue suggests: https://github.com/google/agera

I don't see a reason why one would choose Agera over RxJava2.

The reasons would be that it’s more lightweight, but I don’t know of anyone who has tried it out. @miha-x64 have you tried it out?

what do you mean by lightweight actually

@enighma no, I haven’t.

@masc3d small footprint in terms of size (kb and method count)

@enighma having proguard this is a debug build concern only, right

@masc3d Using, proguard was one of the solutions. But it’s hard to tell how much of the 600+ kb I can get rid of in a normal project.

@enighma hm. with

rxjava

becoming the defacto reactive standard for java and more and more building on it (

rxbinding

,

rxlifecycle

etc.) this would probably not be reason enough for me to switch.

Yes, but if you’re building an Android app and want use instant apps and have a limit of 4MB (I think that was the limit) you have to be careful about which libraries you pull in. Especially if they have a large footprint.

@enighma especially considering those size/method count constraints will become less and less relevant

@masc3d not for instant apps though

so ~1000 methods and ~220kb including rxkotlin is too bulky

@masc3d isn’t the RxJava jar over 600kb?

@enighma even larger yes, but proguard brings it down to that size

Yeah, that I understand, but how much depends on how many of the operators you use and I’m curious how many I would use is a standard project.

that’s true, I took this from a project of mine, so this would probably be a realistic value
