# This file is meant to be included into a target to provide a rule
# to generate jni bindings for Java-files in a consistent manner.
#
# To use this, create a gyp target with the following form:
# {
#   'target_name': 'base_jni_headers',
#   'type': 'none',
#   'variables': {
#       'java_sources': [
#         'android/java/org/chromium/base/BuildInfo.java',
#         'android/java/org/chromium/base/PathUtils.java',
#         'android/java/org/chromium/base/SystemMessageHandler.java',
#       ],
#       'jni_headers': [
#         '<(SHARED_INTERMEDIATE_DIR)/base/jni/build_info_jni.h',
#         '<(SHARED_INTERMEDIATE_DIR)/base/jni/path_utils_jni.h',
#         '<(SHARED_INTERMEDIATE_DIR)/base/jni/system_message_handler_jni.h',
#       ],
#   },
#   'includes': [ '../build/jni_generator.gypi' ],
# }
#
# The ordering of the java_sources must match the ordering of jni_headers. The
# result is that for each Java file listed in java_sources, the corresponding
# entry in jni_headers contains the JNI bindings produced from running the
# jni_generator on the input file.
#
# See base/android/jni_generator/jni_generator.py for more info about the
# format of generating JNI bindings.
