ant build is library project

需求：

android project编译时，需要引用另一个android project项目，另一个android project为is library。现需要通过ant 把两个项目同时打包。

原理：

使用统一build.xml把android project与is library project 的gen生成到android project/gen，把class生成到android project/bin/class中。

方法：

把build.xml放到android project中，修改build.properties中的配置

build.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<project name="APPNAME" default="release" basedir=".">
<property file="config.properties"/>
<property file="build.properties"/>
