scripts/sync-android.sh

#!/bin/bash
#
# This script sync and builds the AOSP source for a specified platform version.
#
# Usage:
#   sync-android.sh <src root> <android version>
#
# This will create a <src root>/aosp-<android version>, sync the source for that version, and
# attempt to build.
#
# You may need to customize the JAVA_6 or JAVA_7 install locations environment variables, or ensure
# the right version of java is in your PATH when versions earlier than nougat. See
# https://source.android.com/source/requirements#jdk for more details.
#
# See README.md for additional instructions

JAVA_6=/usr/lib/jvm/jdk1.6.0_45/bin
