Developed by JetBrains, Kotlin is an officially supported language for Android development that was officially launched in February 2016. The statically typed programming language has soon become popular among android developers due to its ease of use. One of the most significant advantages that Kotlin has over Java is that one can write the same algorithm in Kotlin with fewer lines of code. Besides, it is compatible with the latest version of Java, which allows one to convert their application developed using Java to Kotlin easily. Such advantages have assisted developers to quickly build android applications and launch in the market. According to GitHub, Kotlin was fourth in the fastest-growing languages in 2019, only behind Dart, Rust and HCL. And one of the reasons why Java lost the first position to Python on GitHub is that android developers are moving away from Java to Kotlin.
Here are the top 7 free resources to learn Kotlin and make powerful android applications:-
