此脚本是针对于android在线更新的SDK，以前android有离线安装包，后来改为直接在线安装进行，两者的成本在于sdk的路径和一些工具类的路径不同。
此脚本用于进行自动编译用户需要的APK安装包，使用时候，请将签名用的*.keystore放在和build.xml同一目录，并命名为android.keystore，（如想更改，请在build.xml 中的jarsigner target进行更改）

如果keystore不在此目录，
你就修改 ： <target name="jarsigner" depends="release">

<arg value="-storepass" />
<arg value="${password}" />
<arg value="-keystore" />

<arg value="${out-unsigned-package-ospath}" />
<arg value="android" />
</exec>
</target> 中的
<arg value="android.keystore" />
<arg value="android" />
路径， 这个两个参数值要一样即可
