* IMPORTANT NOTE: The variables defined here must _not_ be 'final'.
* The reason for this is very subtle:
* - This template is used to generate several distinct, but similar
* files used in different contexts:
* o .../gen/templates/org/chromium/base/library_loader/
* This file is used to build base.jar, which is the library
* jar used by chromium projects. However, the
* corresponding NativeLibraries.class file will _not_ be part
* of the final base.jar.
* o .../$PROJECT/native_libraries_java/
* This file is used to build an APK (e.g. $PROJECT
* could be 'content_shell_apk'). Its content will depend on
* this target's specific build configuration, and differ from
* the source file above.
* - During the final link, all .jar files are linked together into
* a single .dex file, and the second version of NativeLibraries.class
* will be put into the final output file, and used at runtime.
* - If the variables were defined as 'final', their value would be
* optimized out inside of 'base.jar', and could not be specialized
* for every chromium program. This, however, doesn't apply to arrays of
* strings, which can be defined as final.
* This exotic scheme is used to avoid injecting project-specific, or
* even build-specific, values into the base layer. E.g. this is
* how the component build is supported on Android without modifying
* the sources of each and every Chromium-based target.
