Ray Wenderlich is having a sale on a few Android books - one of which is is about reactive programming with Kotlin on Android. Check it out if you're interested! <https://www.raywenderlich.com/2887766-advanced-spring-fling-sale-ends-this-friday-may-10>

I'm a bit biased because I helped write the reactive programming book, but I do think it's a great source of information. Also the other books RW offers are all fantastic and worth checking out
