# The version code scheme for the package apk is:
#      Mmbbbtad
# where
#    M - major version (one or more digits)
#    m - minor version (exactly 1 digit)
#  bbb - manually specified build number (exactly 3 digits)
#    t - build type (exactly 1 digit).  Current valid values are:
#           0 : eng build
#           1 : build server build
#    a - device architecture (exactly 1 digit).  Current valid values are:
#           0 : non-native
#           1 : armv5te
#           3 : armv7-a
#           5 : mips
#           7 : x86
#    d - asset density (exactly 1 digit).  Current valid values are:
#           0 : all densities
#           2 : mdpi
#           4 : hdpi
#           6 : xhdpi
# Mmbbb is specified manually.  tad is automatically set during the build.
#
# For the client jar, the version code is agnostic to the target architecture and density: Mmbbbt00
#
# NOTE: arch needs to be more significant than density because x86 devices support running ARM
# code in emulation mode, so all x86 versions must be higher than all ARM versions to ensure
# we deliver true x86 code to those devices.
