This folder is where you would put your instrumented tests. It starts out with a skeleton unit test file.
This folder is where you would put your unit tests. This folder contains the Java and Kotlin source code files for your app. The folder contains three main subfolders: : All your Java and Kotlin language files are well organized here. This file describes all components of your Android Application and the Android run-time system compiles it when your app is executing.Īfter that, Expand the java folder file. This Manifests folder contains the AndroidMainifests.XML file. Then you have to Expand the Manifests folder.

The features it offers made an increasing number of developers start building apps, with it even way before Google made it an officially supported language for Android development. It becomes useful for Android developers, as features like extension functions have allowed developers to write useful abstractions (see Kotlin Android Extensions), which makes code much more concise and readable. IntelliJ (JetBrains IDE for Java) even allows direct conversion of Java code to Kotlin. This means you can write Kotlin and Java in the same project, and they will work together. Because Java and Kotlin are highly compatible, we can use them together in the same project.įor the JVM, it compiles to Java byte-code and it’s completely interoperable with Java. It has many features like functions, operator overloading, and lambda expressions. Kotlin is a statically typed programming language for the JVM(Java Virtual Machine), Android, and the browser which is now officially supported by Google For Android. Kotlin is a programming language that was developed by Jet Brains for modern multi-platform applications.
