build_android_project.sh

#!/bin/bash

# This script can be invoked manually or by a jenkins job, and performs the
# the full Android build process with 'ant' for internal releases (signed with
# debug key) or external ones (signed with release key for Google, unsigned
# and converted market:// links for submission to Amazon).
#
# Usage
#
#   build_android_project.sh <ACTION> <WORKSPACE_DIR> [<RELATIVE_PROJECT_PATH>]
#
# Actions
#
#   --debug ..... build signed apk with debug key 
#   --release ... build signed apk with release key for google, unsigned apk  
#                 for amazon (with replaces market links) 
#
# Example Usage
#
#   # build project in current directory
#   build_android_project.sh --release .
#
#   # build project in ./source/ which references library in ./lib1/
#   build_android_project.sh --release . source
#
# Overview
#
#   1. checks that the Android project has all files in place
#   2. builds the current version
#   3. after building, the apk's are renamed to include 'debug' or 'release'
#      and 'Google' or 'Amazon' as well as the date, and can be found in bin/
#
# Amazon Market
#
#   Requires that all market:// links are replaced with links to Amazon's
#   website. This script automatically replaces all links and exits with
#   an error if there were links that couldn't be converted (which would
#   cause Amazon to reject the app submission.
#
# Required files:
#
#   default.properties (contains android-version to build for)
#
# Optional files:
#
#   build.properties (may contain the keystore infos including
#   passwords for alias and key to auto-sign the apk)
#
#   build.xml files are ignored and replaced on hudson with the
#   most current one from 'android update project'
