JAVAFX on ANDROID

[Felipe Heidrich]

Hi, I'm not familiar with the Android build process but basically this is what you need:

Build graphics/src/main/native-font/fontpath_linux.c to a library called "javafx_font", that it will be loaded by PrismFontFactory.java (but used by FontConfigManager.java).
This is our fontconfig binding used to locate fonts. All references to fontconfig in the native code are dynamic, so you should only need the JNI references while building this object.


Build 
graphics/src/main/native-font/freetype.c
and
graphics/src/main/native-font/pango.c
To a library named "javafx-font-pango"

The cc flags to build them are "pkg-config --cflags pangoft2" + "-D_ENABLE_PANGO", the lib flags are pkg-config --libs pangoft2
(see rt/buildSrc/linux.gradle, search pangoCCFlags and pangoLinkFlags).

This library will be used by graphics/src/main/java/com/sun/javafx/font/pango/OS.java

During runtime you will need to explicitly set "-Dprism.text=native" so that PangoFactory.java is used (instead of T2KFactory.java).

Note: if that is too hard to build pango.o I suppose you could link javafx-font-pango.so only with freetype.o, you should not see any unsatisfied link exception as long as PangoFactory.createGlyphLayout is not called.

Setting -Dprism.debugfonts=true should help to see what is getting loaded, -Djavafx.verbose=true prints what library as being loaded by JFX.

Regards,
Felipe
