Re: JavaFX on Android build (instructions)
Hello Tomas,
I attached the patch for the FXActivity and DalvikLauncher classes. To
make this work, you need to patch the build process for the created
projects as well. I couldn't find where this is done in the repo, so I
did this manually every time :-), this is also the reason why it isn't
included in the patch file. This is not optimized so there is still a
hardcoded reference to the application jar in here, perhaps you can
generalize this:
custom_rules.xml:
target init-env:
add
target install-application:
change to
build-extras.xml:
add
value="${out.absolute.dir}/app_dex/${dex.file.name}"/>
right after the first
I hope I didn't forget anything.
Kind regards,
Sebastian

Hi again,
I just wanted to let you know that I solved the issue with the max

accomplish this I patched the classes FXActivity and DalvikLauncher

patched the build process so that any application jar can be used for
this. If anyone runs into the same issue, just contact me.

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.

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

Re: JavaFX on Android build (instructions)
Thanks Johan for gathering this information! I just tried to run my simple JavaFx application on Android with your build instructions, and I got it build and deployed rather easily. When trying to run it the UI appeared (albeit rather distorted), but when touching the app it crashed, I guess because of the know touch issues. Also, my app was using Google Guice, which gave me some reflection errors when trying the run it on the device (it crashed upon startup). So I swapped Guice with RoboGuice and it worked (for as far as I could test it). So for anyone who wants some dependency injection in their JavaFx Android app, try out RoboGuice as it seems to work.

Re: JavaFX on Android build (instructions)
Thanks Johan for stepping up to the plate on this one. Whilst I've not been actively involved with the iOS and Android work, I have been observing the community interest and progress. I was getting very close to the point of proposing a similar project myself, as I was very worried about community duplication of effort. I think if people interested in this can rally around a single project then the progress will be swifter and you can all share in the reward. -- Jonathan On 17/11/2013 7:53 a.m., Johan Vos wrote: > 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.
