About the Author

Tadas Subonis had began coding approximately whilst he used to be 13. on account that then, he has performed programming with personal home page, JavaScript, Python, C++, and Java (the language within which he most likely has written the main code). He took onto Android fairly lately – round 2014 (while he had a number of extra mild attempts in 2012).

However, he has quickly discovered that Android lacks an honest help for asynchronous programming (Async job was/is a shaggy dog story) whereas extra reckless languages comparable to JavaScript had offers for a very long time. additionally, Java’s common library was once missing a good help for sensible programming primitives (map, filter out) yet that was once simply fixable with libraries reminiscent of Guava.

This lead me to a seek of a library that will support me in achieving Promise-like performance and interface. It didn’t take lengthy until eventually I’ve came upon ReactiveX and their relatives of implementations (including RxJava) to deal with streams in reactive type. It wasn’t precisely the circulate of Promised-like structures yet quickly sufficient I’ve discovered that it’s anything much more powerful.

Since then, he has been utilizing RxJava (and RxKotlin) for his day-by-day Android programming. the standard of the code (lack of insects, clarity, and maintainability) greater ten-fold. Snappy and crash-free adventure for the clients of your software is a needs to nowadays whilst festival for person consciousness on app marketplaces is getting fiercer and fiercer.
