# This GYP file stores the dependencies necessary to build Skia on the Android
# platform. The OS doesn't provide many stable libraries as part of the
# distribution so we have to build a few of them ourselves.
#
# NOTE: We tried adding the gyp file to the android/ directory at the root of
# the Skia repo, but that resulted in the generated makefiles being created
# outside of the out directory. We may be able to move the bulk of this gyp
# to the /android directory and put a simple shim here, but that has yet to be
# tested.
