首先这里是自己花了整整一个下午的时间查找整理出来的，借鉴了一个比较不错博客，也很感谢他的详细步骤。
支持的格式如下：
我的环境是win8.1专业版。
zxing官网说明：https://github.com/zxing/zxing/wiki/Getting-Started-Developing
源码下载：https://github.com/zxing/zxing
或者releases版本：https://github.com/zxing/zxing/releases（其实都差不多一样）
需要的工具：
Ant: http://ant.apache.org/bindownload.cgi
Maven: http://maven.apache.org/download.cgi
然后下载的东西都解压我的是桌面临时创建的一个文件夹test
下面就是分别配置ant和Maven环境变量了，至于怎么进入系统环境变量，我就不那么墨迹的说了，只给截图我认为关键的地方。
两个方法一样，我这里配置ant一个给大家看看：
就是你刚刚解压的位置我的如下到bin目录下复制
C:\Users\xiang\Desktop\test\apache-ant-1.9.4-bin\apache-ant-1.9.4\bin;
path里面最后加英文分号，然后把我的那个路径贴进去，你们的都要贴自己的路径，
然后运行cmd，输入ant验证
这就ok了。
Maven的配置方法不在赘述，
这就ok了。
确保你已经有了java运行环境，如JAVA_HOME、CLASSPATH、PATH都配置好了
进入到zxing-master\android目录，输入命令：android update project --path .
（上面的命令不要省略“--”和后面的点）
1 C:\Users\xiang\Desktop\test\zxing-master\android>android update project --path. 2 Error: Flag ‘--path.‘ is not valid for ‘update project‘. 3 4 Usage: 5 android [global options] update project [action options] 6 Global options: 7 -h --help : Help on a specific command. 8 -v --verbose : Verbose mode, shows errors, warnings and all messages. 9 --clear-cache: Clear the SDK Manager repository manifest cache. 10 -s --silent : Silent mode, shows errors only. 11 12 Action "update project": 13 Updates an Android project (must already have an AndroidManifest.xml). 14 Options: 15 -l --library : Directory of an Android library to add, relative to this 16 project‘s directory. 17 -p --path : The project‘s directory. [required] 18 -n --name : Project name. 19 -t --target : Target ID to set for the project. 20 -s --subprojects: Also updates any projects in sub-folders, such as test 21 projects.
出错了，需要我们提供一个target，输入命令：android list targets
C:\Users\xiang\Desktop\test\zxing-master\android>android list targets Available Android targets: ---------- id: 1 or "android-8" Name: Android 2.2 Type: Platform API level: 8 Revision: 3 Skins: HVGA, QVGA, WQVGA400, WQVGA432, WVGA800 (default), WVGA854 Tag/ABIs : default/armeabi ---------- id: 2 or "android-18" Name: Android 4.3.1 Type: Platform API level: 18 Revision: 3 Skins: HVGA, QVGA, WQVGA400, WQVGA432, WSVGA, WVGA800 (default), WVGA854, W XGA720, WXGA800, WXGA800-7in Tag/ABIs : default/armeabi-v7a, default/x86 ---------- id: 3 or "android-19" Name: Android 4.4.2 Type: Platform API level: 19 Revision: 4 Skins: HVGA, QVGA, WQVGA400, WQVGA432, WSVGA, WVGA800 (default), WVGA854, W XGA720, WXGA800, WXGA800-7in Tag/ABIs : default/armeabi-v7a, default/x86 ---------- id: 4 or "android-21" Name: Android 5.0 Type: Platform API level: 21 Revision: 1 Skins: HVGA, QVGA, WQVGA400, WQVGA432, WSVGA, WVGA800 (default), WVGA854, W XGA720, WXGA800, WXGA800-7in Tag/ABIs : android-tv/armeabi-v7a, android-tv/x86, default/armeabi-v7a, default /x86, default/x86_64 ---------- id: 5 or "Google Inc.:Google APIs:8" Name: Google APIs Type: Add-On Vendor: Google Inc.

根据输出的ID，加上target，命令：android update project --target 2 --path .
C:\Users\xiang\Desktop\test\zxing-master\android>android update project --target 2 --path . Updated and renamed default.properties to project.properties Updated local.properties No project name specified, using Activity name ‘CaptureActivity‘. If you wish to change it, edit the first line of build.xml. Added file C:\Users\xiang\Desktop\test\zxing-master\android\build.xml Added file C:\Users\xiang\Desktop\test\zxing-master\android\proguard-project.txt
会生成以下文件：
上面生成的文件我已经标注出来了。
其中：local.properties文件的内容是：SDK的目录
# This file is automatically generated by Android Tools. # Do not modify this file -- YOUR CHANGES WILL BE ERASED! # # This file must *NOT* be checked into Version Control Systems, # as it contains information specific to your local configuration. # location of the SDK. This is only used by Ant # For customization when using a Version Control System, please read the # header note. sdk.dir=D:\\adt-bundle-windows-x86_64-20130917\\sdk
编译jar包在zxing-master\core目录下输入：mvn -DskipTests -Dgpg.skip=true install
这里有些地方可能被和谐，导致无法下载，至于FQ或者怎么的，各自显神通吧。
我的成功后如下，你们看看
这就表明ok了。
运行完之后core目录下会生成一个target目录，其中：core-3.1.0.jar就是我们需要的jar包
这个后缀名跟选的版本有点关系，都能使用，我选的这个是id为2的，也就是4.3.1。
我也选过5.0那个，出来的效果是一样的，直接就可以使用了。
下面开始编译Android项目，生成apk了，这里有两种方法：
一、命令实现
继续在cmd下执行，进入zxing-master\android里输入ant debug

一般有两个问题：
一、[gettarget] WARNING: Attribute minSdkVersion in AndroidManifest.xml (15) is higher than the project target API level (14)
原因是：
project.properties文件中配置的target=android-14而AndroidManifest.xml文件中
<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="19"/>
修改ses-sdk android:minSdkVersion="14"就可以了。
（这个我的版本比较高，就没有报这个错）
二、是JDK版本的问题
修改：D:\adt-bundle-windows-x86_64-20130917\sdk\tools\ant\build.xml
<!-- compilation options --> <property name="java.encoding" value="UTF-8" /> <property name="java.target" value="1.5" /> <property name="java.source" value="1.5" /> <property name="java.compilerargs" value="" /> <property name="java.compiler.classpath" value="" />
为如下
<!-- compilation options --> <property name="java.encoding" value="UTF-8" /> <property name="java.target" value="7" /> <property name="java.source" value="7" /> <property name="java.compilerargs" value="" /> <property name="java.compiler.classpath" value="" />
改好之后又有新问题了

没有CameraConfigurationUtils类
搜索下就可以找到，应该在android-core里面有这个类
直接把这个目录拷贝到C:\Users\xiang\Desktop\test\zxing-master\android\src\com\google\zxing\client\android\camera里面
然后再编译，效果图如下，不用多说了
apk已经生成了。你看看
看bin里已经有对应的apk了，自己跑跑看。
二、第二种方法就是直接导入到Eclipse，这种方法我不再详细演示了，直接导入android项目,然后把添加lib文件夹，放入前面生成的jar包，
加入对应的那个类
运行的时候可能会报错。

按照网上很多说法
到处搜索解决方案，终于在google的帮助下解决了。
在eclipse中 Properties -> Java Build Path -> "Order and Export"
在Order and Export选项卡中将core.jar提前到第一位 并选中它
然后clean你的工程,这一步非常重要，别忘记了
重新编译运行就可以了
估计是在core.jar之前的包里已经有了同名的class所以编译之后产生的apk运行时找不到真正的引用。而且这个包也需要被同时发布到程序中去
如果还是有错误的话，那就缺少了javase-3.1.0.jar库
生成办法跟core一样C:\Users\xiang\Desktop\test\zxing-master\javase>mvn -DskipTests -Dgpg.skip=true install
后面我就不贴图了，同样把对应的包放入lib然后add buildpath编译，还有问题，你就考虑考虑吧Eclipse换个高版本的吧。
至于扫描效果图，我真机也就不展示了，截个图给你们看看吧
正常运行代码我稍后添加。
