# The current version code scheme for the package apk is:
# Mbbbba
# where
# M - Chromium milestone number minus 36. (1 or more digits). This is to
# ensure that our version codes are lower than the ones currently used by
# Chrome for Android, so that we can adopt their scheme in future.
# bbbb - manually specified build number (exactly 4 digits). This defaults to
# 0000, or 9999 in local builds.
# a - device architecture (exactly 1 digit). Current valid values are:
# 1 : armv7-a
# 2 : armv8-a (arm64)
# 4 : mips
# 7 : x86
# 8 : x86_64
# 64-bit architectures must be higher than their corresponding 32-bit
# architectures to ensure that 64-bit devices receive the multiarch APK.
# x86 must be higher than ARM to avoid x86 devices receiving ARM APKs
# and running them in emulation.
# TODO(torne): get this from Chromium automatically.
