which technology should give preference

[AmnoJeeuw]

I am learning hands-on how to program using JavaFX and in the process 
doing so I’ve come across FXML; which I find most interesting. Since the 
principal is “Think hand held device first” -TH2DF, my intention is to 
port the my future application to Android device, but I am concerned 
that there will be too many issues when doing that. So, my question is, 
which technology should give preference to, JavaFX or FXML?

Please, keep in mind that I am using a Windows 8.1 machine and 
Eclipse-Photon.


Thanks in advance
