You can see how it is done in another example: HelloFXML. In the case of a mobile it’s not necessary - our app will take the whole available space on the screen.Īnother way to set up and display widgets in JavaFX is to use a WYSIWYG editor called Scene Builder which generates FXML files, a version of XML, that you can then load into your app.

Since we want to test the app on our laptop before we install it on a mobile, we use postInit also to check on which platform the app is being run, and if it’s a desktop, we set the dimensions on the app’s window. The Main class extends MobileApplication from the Glisten library and then construct the main view programmatically, in two methods: init() for creating the widgets, and postInit(Scene) for decorating them.

HelloScala is just a simple example app - the actual Scala code only sets up a few widgets and displays them.

  • javafx-maven-plugin which is a requirement for gluonfx-maven-plugin.
  • #ANDROID STUDIO TUTORIAL WINDOWS#

    From those we will use directly only display (to set the dimensions of the app’s windows in case we run the app on a desktop and not in the full-screen mode on a mobile) and util (to check if we run the app on a desktop or a mobile), but the others are needed by these two and by Gluon Glisten. In its configuration you will find the attachList with Gluon Attach modules we need: device, display, storage, util, statusbar, and lifecycle. gluonfx-maven-plugin lets us compile Gluon dependencies and JavaFX code into a native image.

  • scala-maven-plugin lets us use Scala in Maven builds (well, d’oh).

    For us, it means we should be able to use it to access everything on Android from the local storage to permissions to push notifications. Attach is an abstraction layer over the underlying platform. Glisten enriches JavaFX with additional functionality specifically designed for mobile applications.

  • We will use two Gluon libraries: Glisten and Attach.
  • A tiny Scala library which resolves this problem in the interaction between Scala 2.13 and GraalVM Native Image.
  • In the pom.xml of HelloScala you will find a list of plugins and dependencies our example app uses. If you decide to write something more complex with this tech stack, you will quickly see that you can use Gluon’s libraries and JavaFX (maybe together with ScalaFX) to achieve the same results other developers get by tinkering with Android SDK, while you are writing code that can be easily re-used on other platforms as well. If we are on Android, we can just let the app’s window take the whole screen. It has some interesting implications: for example, you will see in the code that we check if we are on the desktop instead of Android, because if yes then we need to provide window size for our app. Gluon is a company that maintains JavaFX and provides libraries that give us a layer of abstraction between our code and the device - be it desktop, Android, or iOS. HelloScala is based on HelloGluon from Gluon samples. If you reached this point and everything seems to work, it means you probably should be able to compile and run the example app called HelloScala.

    How to build an Android app with GraalVM Native Image Requirements

    android studio tutorial

    At the end of this tutorial, you will find links to materials discussing other options. Here, in this document, we will focus on how to write a modern Android app with Scala that uses GraalVM Native Image and JavaFX. As a consequence, it is possible to write Android apps in Scala, and in fact it’s possible to do it in more than one way. The Android platform runs on Android Runtime which is a virtual machine based on JVM and, although not identical, it’s very similar to it.
