Eclipse下配置Ant脚本 自动打包带签名的Android apk（PC环境为MAC）
虽然eclipse很少用了，但是在古老的项目上还是会用到。一个麻烦事是打带签名包的时候，非常不方便。下边纪录下配置ant，自动打包带签名apk的过程，作为备忘。（PC环境为MAC）
1，第一步得安ant，下载对应安装包，解压后配置环境变量：
export ANT_HOME="/Users/yanzi/work/apache-ant-1.9.4"
export PATH=${PATH}:${ANT_HOME}/bin
通过which ant检查是否安装成功。
2，在项目目录下运行：android update project -p ./ 如果有依赖包，就到每个依赖包目录下再运行下这个命令。运行完这个命令后会多两个文件：build.xml 和 local.properties
local.properties文件内容：
sdk.dir=/Users/yanzi/work/android-tool/android-sdk-macosx
build.xml文件内容：
这两个文件都不用动，最上面project的name里写上自己想要的名字。然后项目根目录下新建个ant.properties，内容如下：
# This file is used to override default values used by the Ant build system. # # This file must be checked in Version Control Systems, as it is # integral to the build system of your project. # This file is only used by the Ant script. # You can use this to override default values such as # 'source.dir' for the location of your java source folder and # 'out.dir' for the location of your output folder. # You can also use it define how the release builds are signed by declaring # the following properties: # 'key.store' for the location of your keystore and # 'key.alias' for the name of the key to use. # The password will be asked during the build when you use the 'release' target. key.alias=com.tongcheng key.store=tongcheng.keystore key.store.password=12377778 key.alias.password=12377778配置上keystore的相关信息。
这样先执行ant clean，然后执行ant release就ok了！
3，当然为了更爽，你还需要下面这个脚本：
vim release.sh,内容如下：
echo -----------------start---------
start=$(date +%s)
ant clean
ant release
adb uninstall com.android.tongcheng
adb install bin/TongCheng-release.apk
end=$(date +%s)
echo "----over,耗时$[${end} - ${start}]秒---"
之后每次想安装带签名的包，直接./release.sh即可！
