// 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.
