Ant打包学习（没有继承sdk的build.xml并且不适用于引用了libraryproject的project）

打包方式有三种：

1、eclipse

2、ant

3、编写批处理主动调用adt工具打包

========================================================================

1、进入命令行模式，并切换到项目目录，执行如下命令为ADT创建的项目添加ant build支持：

android update project -p . -t 17

2、build脚本默认target是help，所以会显示如上信息，修改target为debug或release就可以像无ant时一样编译、生成以及调试了。

3、使用release时  在local.properties添加签名信息

#keystore

key.store=hujiang.p12

key.alias=xxx

key.store.password=xxx

key.alias.password=xxx

======完整如下（没有继承sdk的build.xml并且不适用于引用了libraryproject的project）========================================

<?xml version="1.0" encoding="utf-8"?>

<!-- 步骤 

1.用aapt生成R.java

2.JAVAC编译JAVA文件

3.批处理生成classes.dex

4.aapt打包资源 

5.apkbuilder包资源和类文件为APK文件

6.jarsinger 对APK进行签名-->
