It is a common problem in Android development when your API is not sending you exactly the same data, what you want to show in your views, so you need to implement more complex requests. Possibly your app needs to make multiple requests, that wait for each other, or call multiple requests after the previous one finished. Sometimes you even need to combine these two approaches. This can be challenging in plain Java and will often result in unreadable code, what is also painful to test.
Today I’m going to show you in a simple example how this can be achieved in a clean way using RxJava. The example is written in Kotlin, what makes the code more concise and easy to read. If you are completely new to RxJava or Kotlin, I suggest you catch up on the basics. There are some great resources here as well.
