// Definitions for building the Android core library and associated tests.
//

// The Android core library provides low-level APIs for use by the rest of the
// Android software stack. It is made up of various parts, some of which can be
// found in libcore/ and other parts that can be found in various external/
// directories.
//
// libcore has some sub-directories that follow a common structure:
// e.g. dalvik, dom, harmony-tests, json, jsr166-tests, luni, libart, ojluni,
// support, xml, xmlpull.
//
// The structure of these is generally:
//
//   src/
//       main/               # To be shipped on every device.
//            java/          # Java source for library code.
//            native/        # C/C++ source for library code.
//            resources/     # Support files.
//       test/               # Built only on demand, for testing.
//            java/          # Java source for tests.
//            native/        # C/C++ source for tests (rare).
//            resources/     # Support files.
//
// All subdirectories are optional.

// Provided solely to contribute information about which hidden parts of the

//
// The build system determines that this library provides hiddenapi information
// for the core-oj bootjar because its name is of the form <x>-hiddenapi, where
// <x> is the name of a boot jar. That triggers the generation of a flags.csv
// file which encapsulates information extracted from the UnsupportedAppUsage
// annotations in the dex. The information from that file is then encoded into
// the core-oj file.
//
// Usually, e.g. for core-libart, the UnsupportedAppUsage annotations are
// added to the source that is compiled directly into the bootjar and the build
// system extracts the information about UnsupportedAppUsage directly from
// there.
//
// This approach of having separate annotated source and a separate build
// target was taken for ojluni to avoid having to maintain local patches in the
// ojluni source for UnsupportedAppUsage annotations as that would make it more
// difficult to pull down changes from upstream.
