Hi, I've been using Volley to send HTTP requests to my back-end. However this is causing the application to react slowly since it has to wait for the response in order to actually do anything. I want to make a query when the app first loads and use the data at a later point instead, but I'm unsure how I would go about that. (presumably setting some global variable or smthn) any advice?

How big is your response? How old can it be before need refreshing?

It never needs refreshing, and it's not very large, maybe 500 Bytes

Don't think that such small request could slow down anything. But nothing prevents you from save it to a top level property or in case if Android to Application instance, what is exactly do you want to know?
