Digest of interesting materials for the mobile developer # 290 (March 11 - March 17)

The new digest tells about the idempotency of the API, the struggle of Apple and Spotify, the design laws of the name, the most earning applications and pure gold of mobile games.

Trainee Vasya and his stories about idempotency API

An API is called idempotent, and calling it again does not change state. There is a subtle point here: the result of an idempotent call may vary. For example, when you call the idempotent order creation API again, the order will not be created again, but the API can answer both 200 and 400.

Kotlin as the future of Android application development

Since the advent of version 1.0, only a few years have passed, and many large companies and developers have adopted the language. This is due to the fact that the creators of the language managed to achieve the goals set at the beginning of the path - to develop a tool that would be more convenient and safer than Java, but less complicated than Scala.
