This talk was held during Android Fest BH 2019, that happened on July 6th, in Belo Horizonte, Brazil.
I gave a 40min talk about what's the evolution of Kotlin since version 1.0, how is the status of the language on Android in general, the current state of the language in terms of adoption and user perception and what's new on Kotlin 1.3 for Android developers in terms of new APIs and features.
The content is in pt-BR.
