`Rxify`— a simple spell for complex RxJava operators

Submitted Aug 10, 2016

This talk is about the operators which upon reading the document look daunting at first but if you get a grasp of them, they can be quite useful in almost all the apps you code. RxJava is your friend, it will make your life easier. With RxJava many complex tasks can be accomplished easily and without errors. As the title says, Rxify - you just need to cast the spells and all your work will be done. From hitting the cache-first to performing retries, just cast the spells and you are good to go.


RxJava operators are very useful but a little hard to learn at first. The task of selecting the appropriate operator for a particular scenario. The purpose of this talk will be to make the selection task easier. Giving examples of day-to-day scenarios and explanation of how to apply them. The list of the operators which I will talk about is as follows

  • map()
  • flatmap()
  • concat()
  • merge()
  • debounce()
  • take()
  • repeat()
  • zip()
  • filter()
  • retry()
  • buffer()
  • Others

I will start with the definiton of the operators, explain what it does and then list a scenario in which it can be applied. Will then show a simple code snippet of how to appy those operators. A gist of the talk that I will be presenting can be found on related blog posts on medium (Part1, Part2, Part 3 and Part 4 till now). These posts have also been published on newsletters like androiddevdigest.com importjava.org Part 3 on androiddevdigest.com
