Hi,
I used your instructions with some tweaks to build a JavaFX application
for android on Windows. However, it turns out that Android's dex format
is putting a spoke into our wheel with the 65k method reference limit.
The JavaFX runtime itself already contains 51k method references and
because of that I was not yet able to bring our full application
showcase to android.
So if some android expert could contribute to the project by showing how
to use multiple dex files, one containing the javafx runtime and one for
the application, that would be great. Any help on the mailing list is
appreciated as well.
Kind regards,
Sebastian Rheinnecker

Hi,
Since I (and others) think it is very important that we can have
JavaFX applications running on Android (and IOS, but in this mail I
limit myself to Android), I created a bitbucket project containing
code and build instructions to run JavaFX applications on Android.
I didn't do much myself. Rather, this project is about providing easy
and consistent build instructions. I combined information from this
mailinglist with information I could find online, and with help from
the JavaFX team.
The project is here: https://bitbucket.org/johanvos/jfx78
After I gathered the information, it didn't cost me much time to get
HelloWorld running on my Samsung S3 mini. I never wrote an Android
project before, and I never used the Android SDK or NDK before I
started with this thing almost a week ago. Hence, it is not that hard
to create a JavaFX application on Android.
This project is far from finished. There are a number of things that
have to be done:
* Improve build instructions
* Simplify build
* Fix bugs (e.g. touch-events are not processed yet)
* Manage the synchronization with the main JavaFX repo
* create plugins for IDE's or maven to automatically build the Android packages
I want to open this project at this early stage, though, since I think
it is important to have more community input. Also, I want to give a
shout to the world that JavaFX on Android is not a dream.
I hope many of you try out the instructions, improve them, correct
them, and test your applications on Android.
Thanks a lot to all the people on this mailinglist for telling how
they were dealing with JavaFX on Android. Again, I didn't write much
code, but rather tried to combine the information and make it useful
for everybody.
I know there is an intense debate about the role of Oracle on the
Android (and IOS) ports. Let me close with a similar situation. About
17 years ago (sigh, time flies), I was involved with the port of Java
to Linux, as part of the Blackdown team. Initially, we didn't get much
help from Sun Microsystems (it was even not easy to get the latest
code). But once we showed that we could run the thing on Linux, and
that many developers were interested in it, Sun started to add
resources on this as well. Eventually, we became obsolete. I hope to
reach the obsolete stage on this project as well.
Again, the project can be found here:https://bitbucket.org/johanvos/jfx78
