android - Kotlin 与 JavaFXPorts 的兼容性

Question

我想用 JavaFXPorts 构建一个 JavaFX And​​roid 应用程序和 Kotlin 代码。是否可以在 JavaFXPorts 项目中使用 Kotlin？这是我的示例 Gradle(版本 5.6.4)项目:

Note: Problem with this code is the Kotlin Runtime... Is there any way to bundle everything in the executable Jar and Apk?

你可以，但你可能会在此过程中遇到一些痛苦，我的建议是使用 TornadoFx，它是基于 JavaFx 构建的 Kotlin UI 框架。它真的很好
