 # 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.
 #
 # We tried adding this 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 intended output directory. So to avoid this we created a simple
 # shim here that includes the android_deps.gypi file.  The actual dependencies
 # are defined and maintained in that gypi file.
