#   'type': 'none',
#   'variables': {

#   },
#   '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.
