So I'm reading about Optimistic UI and it's something I would like to implement in my android java app.
My android app connects with my rest api. My confusion is how do I go about this?
I have a products api that I call from the android app to save data. How do I do this using the optimistic ui approach.
The easiest way? I assume the rest API will either call a callback, or send a message some other way (like rxJava or a message bus). Have your rest API call the callback/send the message once with the optimistic result, then again with the real result.
Remember that the problem with an optimistic result is that its a (possibly educated) guess. It can be very wrong. So there's places where its a viable solution, and places it isn't. For example, a banking app shouldn't optimistically guess someone's balance. I'd say the number of places where it makes sense are dwarfed by the number it doesn't.
