# This script imports the translations from the Translation Console into
# TalkBack. It puts the resulting files directly into the res/values-??/
# directories and does a g4 add or g4 edit on them, but you have to create
# the changelist to submit the changes.
#
# Note that the translation system that Android uses is different than other
# systems in google3, so a special android-internal tool must be built and
# used. Here are the full instructions, from scratch:
#
# 1. Get android-internal
#
# 2. Compile all of Android
#
# bash
# source build/envsetup.sh
# make -j 8
# wait an hour
#
# 3. It's okay if something fails, but make sure transconsole is compiled:
#
# mmm vendor/google/tools/transconsole
#
# 4. Add out/host/linux-x86/bin to your path (transconsole is there)
#
# 5. Update the list of locales below, look at the file
#    vendor/google/tools/localization/import-from-xtb in the android-internal
#    source to get the best list.
#
# 6. Update the list of xml files containing strings (look in res/values/
#    inside TalkBack)
#
# 7. Now run this script from your google3 directory like this:
#      sh research/android/marvin/talkback/import_translations.sh
#
# 8. Make a changelist with research/android/marvin/talkback/res/...
