Android Question PubSub Library for B4A

[deboerr]

Greetings all ... B4A noob here.

Is there a simple PubSub event library for B4A which I can use for global async communication between classes or activities.
A library that includes a couple of methods like ON (or LISTEN) and EMIT

eg
- <Object>.ON("START_IMPORT", Callback_Sub)
- <Object>.EMIT("START_IMPORT", Data_Passed_to_Each_Listener)

Sorry if it's a stupid question.

cheers

Don't use activities and everything will be simpler. Switch to B4XPages.
It is not a stupid question at all.

I don't think that anyone has created such library, but it should be quite simple to implement using CallSub / CallSubDelayed.
