# This file is meant to be included into a target to provide a rule
# to build Android APKs in a consistent manner.
#
# To use this, create a gyp target with the following form:
# {
#   'target_name': 'my_package_apk',
#   'type': 'none',
#   'variables': {
#     'apk_name': 'MyPackage',
#     'java_in_dir': 'path/to/package/root',
#     'resource_dir': 'path/to/package/root/res',
#   },
#   'includes': ['path/to/this/gypi/file'],
# }
#
# Required variables:
#  apk_name - The final apk will be named <apk_name>.apk
#  java_in_dir - The top-level java directory. The src should be in
#    <(java_in_dir)/src.
# Optional/automatic variables:
#  additional_input_paths - These paths will be included in the 'inputs' list to
#    ensure that this target is rebuilt when one of these paths changes.
#  additional_res_dirs - Additional directories containing Android resources.
#  additional_res_packages - Package names of the R.java files corresponding to
#    each directory in additional_res_dirs.
#  additional_src_dirs - Additional directories with .java files to be compiled
#    and included in the output of this target.
#  asset_location - The directory where assets are located.
#  generated_src_dirs - Same as additional_src_dirs except used for .java files
#    that are generated at build time. This should be set automatically by a
#    target's dependencies. The .java files in these directories are not
#    included in the 'inputs' list (unlike additional_src_dirs).
#  input_jars_paths - The path to jars to be included in the classpath. This
#    should be filled automatically by depending on the appropriate targets.
#  is_test_apk - Set to 1 if building a test apk.  This prevents resources from
#    dependencies from being re-included.
#  native_libs_paths - The path to any native library to be included in this
#    target. This should be a path in <(SHARED_LIB_DIR). A stripped copy of
#    the library will be included in the apk.
#  resource_dir - The directory for resources.
#  R_package - A custom Java package to generate the resource file R.java in.
#    By default, the package given in AndroidManifest.xml will be used.
#  java_strings_grd - The name of the grd file from which to generate localized
#    strings.xml files, if any.
#  library_manifest_paths'- Paths to additional AndroidManifest.xml files from
#    libraries.
