 # 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.
