# 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': {
#     'package_name': 'my_package',
#     'apk_name': 'MyPackage',
#     'java_in_dir': 'path/to/package/root',
#     'resource_dir': 'res',
#   },
#   'includes': ['path/to/this/gypi/file'],
# }
#
# Note that this assumes that there's an ant buildfile <package_name>_apk.xml in
# java_in_dir. So, if you have package_name="content_shell" and
# java_in_dir="content/shell/android/java" you should have a directory structure
# like:
#
# content/shell/android/java/content_shell_apk.xml
# content/shell/android/java/src/chromium/base/Foo.java
# content/shell/android/java/src/chromium/base/Bar.java
#
# Required variables:
#  package_name - Used to name the intermediate output directory and in the
#    names of some output files.
#  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_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 (default:
#    <PRODUCT_DIR>/<package_name>/assets).
#  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.
#  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 and symbolic links to the
#    unstripped copy will be added to <(android_product_out) to enable native
#    debugging.
#  resource_dir - The directory for resources.
