# Use of this source code is governed by a BSD-style license that can be
# found in the LICENSE file.
# 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_lib_target - The target_name of the target which generates the final
# shared library to be included in this apk. 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.
