In this tutorial we build JavaFX Hello World on Android. It is worth noting that if you are planning to write an exclusive Android app, you'll be better off using Android Studio and native Android API. On the other hand, JavaFX allows writing cross-platform (desktop, Android, iOS) apps with small to no code change.
Note: this tutorial may be outdated.
