gyp/android_system.gyp

# 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. 

{
  # Define the location of the required Android sources, allowing for override
  # in GYP_DEFINES.
  #
  # These sources are necessary because they must be built using the Android
  # toolchain and they are not expected to be present on the host OS.
