The major difference between RxAndroid and RxJava is Schedulers. Why were early 3D games so full of muted colours? Why would people invest in very-long-term commercial space exploration projects? There is the third solution by: AbacusUtil. According to documentation: A small regret about introducing backpressure in RxJava 0.x is that instead of having a separate > base reactive class, the Observable itself was retrofitted. Could you provide a simple example using the existing retrofit implementation so I can award you the bounty? RxJava is designed to take the pain out of working with asynchronous streams of data—although as you'll see, RxJava's definition of "data" is pretty broad. RxJava on Android They are simple to use and do not require any 3rd party lib integration. With this schedulers, you can define an observable which does its work in a background thread, and post our results to the main thread. Project Set-Up. Why you should use RxJava in Android a short introduction to RxJava. back in RxJava 1, ... there is an alternative solution with the new announced Android Jetpacks Libraries: Paging Library. There's no need to call .subscribeOn(Schedulers.io()) as RetroFit already takes care of this -, @MartynasJurkus additionally to stuff said by ataulm, unlike. I read a retrofit example (because I'm extremely familiar with it) of a simple request and it was ten or fifteen lines of code and my first reaction was you gotta be kidding me =/ . while doing something else in the background (networking). For simple networking stuff, the advantages of RxJava over Callback is very limited. First off subscribeOn and observeOn are not necessary with retrofit. One minor feedback. RxJava 2 is this idea that we want to take the things which are fundamentally asynchronous in Android, whether it be the network, Android itself, a database, or even the UI, and write code that reacts to changes in these sources instead of trying to cope with changes and manage state ourselves. How come there are so few TNOs the Voyager probes and New Horizons can visit? Source. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. When I asked this, I really needed the answer to the question - so I offered a bounty. and there is no need in flatmap, 3 answers from @Niels. your coworkers to find and share information. For now, let's ignore the error handling. Making statements based on opinion; back them up with references or personal experience. I'm working on networking for my app. Why do we need to use RxAndroid with RxJava? RxAndroid can be understood as an extension to RxJava, that helps you to use it on Android platform easily. It will do the network call asynchronously and notify on the same thread as the caller.
