8u20b2 available for download

[Johan Vos]

Hi,

I just uploaded dalvik-sdk-8u20b2 to https://bitbucket.org/javafxports/android/downloads/dalvik-sdk-8u20b2.zip
Most important changes:
* support for WebView
* fix for lifecycle crashes
* the dalvik-sdk now contains a "samples" directory with currently 1 sample: HelloWorld

I can use some feedback on the HelloWorld sample. If everything goes well, you have to change only a single parameter (the location of the downloaded Android SDK) and apart from that, the preconfigured parameters should work. The result of the process described in the samples/HelloWorld/README is an apk that can be installed on a device.
I tested it on Linux and Mac OS X and I am looking for a version of the "convertJavaFXToAndroid" script for Windows. Who can help with this?

Thanks,

- Johan

I am able to build my project with no errors.

But it fails in the start(Stage) method.

I have narrowed the failure down to one of these two lines (Where root is a BorderPane)

        Rectangle2D b = screen.getVisualBounds();

        Scene scene = new Scene(root, b.getWidth(), b.getHeight());

The logcat has this

So a font seems to be missing?

I have no idea what I need to do to fix this.

BTW Today is a holiday here in the States. I may not be doing any more on this until Tuesday.

[Johan Vos]

My mistake. I double-checked and then created the build on a system without freetype support.
I corrected that, and uploaded b2 again. There were only a few downloads yet, so apologizes to the early adopters that already downloaded it.

Thank you very much for reporting this issue so fast!

What version of Android is this? Can you show a bit more of the logcat output, e.g. starting here:
V/FXActivity(....): onCreate called, using 8udev

Can you attach the .apk that has been created?

This seems to be similar as https://bitbucket.org/javafxports/android/issue/39/crash-helloworld

The strange thing is that the .apk that caused the crash there, is working fine on devices with API level 16 and 19.

[Johan Vos]

... the reason for this might be similar to the reason in https://bitbucket.org/javafxports/android/issue/39/crash-helloworld

Are you using an emulator instead of a real device? Emulators won't work at this moment, due to missing opengl extensions.
