Crash when using SXSSFWorkbook: ava.lang.NoClassDefFoundError: Failed resolution of: Ljava/awt/font/FontRenderContext; about poi-on-android

[centic9]

I have now cherry-picked changes from LePat@d38372b onto branch https://github.com/centic9/poi-on-android/commits/add_dummy_autosize to show how such missing classes from java.awt can be added.

But as the implementation just provides dummy implementations of the methods, I did not merge it into master. The resulting autosized column widths are far off and will not be useful unless a more sophisticated solution is implemented.

If you just want to get SXSSFWorkbook to work should be able to fetch these changes from there in your fork.

It can also serve as example of how to add a more useful implementation in the future.

Android does not provide the java.awt.* packages and also actively refuses if you try to add such classes, this means any part of Apache POI which uses java.awt.* stuff will currently fail this way.

I did some workaround with shading for java.awt.Color before, you can try to do the same for Dimension, see https://github.com/centic9/poi-on-android/blob/master/poishadow/build.gradle#L39 and https://github.com/centic9/poi-on-android/tree/master/poishadow/src/main/java/org/apache/poi/java/awt

The same issue is triggered by calling Sheet.autoSizeColumn(Int row), this also needs the FontRenderContext.
Thanks for adding the example of how to add implementations for missing classes!
