Missing header files in j2objc 2.3 JRE.framework (android/icu/text/UForwardCharacterIterator.h)

[sarsonj]

Hi,

we upgraded to j2objc 2.3. After clean recompile of our project we got compilation error related new support of Android ICU. It looks like, that some referenced header files are not included in JRE.framework. We are using precompiled zip file downloaded from j2objc site.

But there is no UForwardCharacterIterator.h in JRE.framework in android/icu/text/UForwardCharacterIterator.h.

Thanks,

Jindrich

Hi,

I see, this class is hidden in the Android ICU version:
https://android.googlesource.com/platform/external/icu/+/oreo-release/android_icu4j/src/main/java/android/icu/text/UForwardCharacterIterator.java#58

But in our case, we should expose the header file because UCharacterIterator implements UForwardCharacterIterator.

In case I am missing something, your project should be using this new functionality somehow, maybe through a java.time class? Could you share the list (stack) of include files that lead to UCharacterIterator?

Thanks,
Antonio.

Hi,

I don't use any new functionality, but this happen when nothing more but using framework JRE provided by j2ObjC distribution:

@import JRE;

This UCharacterIterator.h is in JRE.framework, not in my generated code. And it references to non-existing file in this framework.

Have a nice day,
Jindrich

Thanks for the additional details! I'll make sure the header is included in the next release. In the meantime, please copy the attached header (rename to .h)
UForwardCharacterIterator.txt

to the following locations inside the J2ObjC distribution folder:
include/android/icu/text/UForwardCharacterIterator.h
frameworks/JRE.framework/Versions/A/Headers/android/icu/text/UForwardCharacterIterator.h

Fixed in 2.3.1.
