So here you’ve defined the adapter as a lateinit variable - lateinit is telling Kotlin that you want to initialize this at some stage after creation, not the default in Kotlin classes - normally you have to initialize things immediately. For example, often you’ll see curly brackets used as function parameters:īuildscript It resembles other languages you may have seen but some things look off, often because it is so concise!ĭon’t panic - because it is so extensible there are many ways to write the same code, and many shortcuts that aren’t available in other languages. Here is the complete code if you rather go straight to the end.īefore we start, let’s talk a bit about Kotlin. If you don’t have any Android experience you should be able to follow along but you might have to Google a few things here and there. I’m going to assume you have some Java experience and have at least played around with creating an Android app. Spring Boot is a great way to create a robust REST API with a minimal amount of code.
In this tutorial, you’ll use Spring Boot for the API that powers your Android (+ Kotlin) mobile app. The best way to start is by creating a complete app yourself, which you’ll do in this tutorial. Similarly Windows and Linux are done too.Kotlin was recently given official Android support status by Google, but it remains difficult to understand for many developers. name: Build with Gradle with: arguments: macosX64Binaries # to build mac binary - name: Upload MacOS Build uses: with: name: macos-build path: build/bin/macosX64/releaseExecutable/ParkingLot-LLD-Kotlin-MPP.kexe MacOS build_macos: runs-on: macos-latest # build this on a Mac steps. name: Build with Gradle with: arguments: assembleDist # java distribution - name: Upload JVM Build uses: with: name: jvm-build path: build/distributions/ParkingLot-LLD-Kotlin-MPP-*.zip # this is the path where it is created 3.

So how does that work, you'll ask? Here's how. exe executable (via mingw)Īnd they way I have set it up on Github, on every tag, it releases all these binaries. The interesting thing is, it is made using Kotlin Multiplatform, which means it can be compiled to the following formats You can check the following terminal recording. So I recently made a Parking Lot CLI program (the kind of ones you make for low-level system design interview questions).
