 # 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'],
 # }
 #
-# If you have package_name="content_shell" and
+# 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/org/chromium/base/Foo.java
 # content/shell/android/java/src/org/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_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 absolute path to the directory where assets are located
-#    (default: <(ant_build_out)/<(package_name)/assets).
+#  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.
 #  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
