# in order to easily ship to Android 23 devices (and, by extension, all devices
# before Android 23).
#
# Google did not remove all code that referenced said package in their own
# com.google.android.gms namespace!  It turns out that the org.apache.http
# package is not removed, only deprecated and hidden by default.  Google added a
# a `useLibrary` Gradle directive that allows legacy code to reference the
# package, which is still (hidden) in the Android 23 platform.
#
# Fennec code doesn't need to compile against the deprecated package, since our
# code doesn't reference the package anymore.  However, we do need to Proguard
# against the deprecated package.  If we don't, Proguard -- which is a global
# optimization -- sees Google libraries referencing "non-existent" libraries and
# complains.  The solution is to mimic the `useLibraries` directive by declaring
# the legacy package as a provided library jar.

# [Comment 1/3] We don't have correct dependencies for strings.xml at

# multiple strings.xml files, and we need to rebuild gecko.ap_ if any
# of them change.  But!  mobile/android/base/locales does not have
# enough information to actually build res/values/strings.xml during a
# language repack.  So rather than adding rules into the main
# makefile, and trying to work around the lack of information, we
# force a rebuild of gecko.ap_ during packaging.  See below.

# Since the sub-Make is forced, it doesn't matter that we touch the
# target file before the command.  If in the future we stop forcing
# the sub-Make, touching the target file first is better, because the
# sub-Make outputs will be fresher than the target, and not require
# rebuilding.  This is all safe because Make removes the target file
# if any recipe command fails. It is crucial that the sub-Make touch
