Android二维码开源项目zxing编译

浏览数：70 / 时间：2015年06月11日

ZXing是一个开放源码的，用Java实现的多种格式的1D/2D条码图像处理库，它包含了联系到其他语言的端口。Zxing可以实现使用手机的内置的摄像头完成条形码的扫描及解码。该项目可实现的条形码编码和解码。

目前支持以下格式：

zxing官网说明：https://github.com/zxing/zxing/wiki/Getting-Started-Developing

源码下载：https://github.com/zxing/zxing

我下载的是releases版本：https://github.com/zxing/zxing/releases

需要的工具：

Ant: http://ant.apache.org/bindownload.cgi

Maven: http://maven.apache.org/download.cgi

我下载的是Windows版的，如果是Linux需要下载Linux版，这里只尝试Windows下编译。

下载后在合适的目录下解压，将bin目录添加到环境变量，跟JDK方法一样。

这里只配置下ant的环境变量

1.我的电脑右键

2.点击“属性”

3.点击“环境变量”

4.点击“编辑”

添加解压后的bin到Path就可以了，记得用;结束，验证下

配置编译

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-zxing-3.1.0\android目录，输入命令：android update project --path .

D:\zxing\zxing-zxing-3.1.0\android>android update project --path .
Error: The project either has no target set or the target is invalid.
Please provide a --target to the 'android.bat update' command.

D:\zxing\zxing-zxing-3.1.0\android>

但提示出错了，需要我们提供一个target，输入命令：android list targets

根据输出的ID，加上target，命令：android update project --target 7 --path .

D:\zxing\zxing-zxing-3.1.0\android>android update project --target 7 --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 D:\zxing\zxing-zxing-3.1.0\android\build.xml
Added file D:\zxing\zxing-zxing-3.1.0\android\proguard-project.txt

D:\zxing\zxing-zxing-3.1.0\android>

会生成以下文件

BUILD FAILED

D:\zxing\zxing-zxing-3.1.0\android>

这里报了两个问题

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。

二、是JDK版本的问题

修改：E:\Android\adt-bundle-windows-x86\sdk\tools\ant\build.xml

<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="" />

改成

<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="" />

前面的错误没有了，但出现新的问题

缺少CameraConfigurationUtils类

通过搜索，在以下目录找到了这个类

直接把这个目录拷贝到D:\zxing\zxing-zxing-3.1.0\android\src\com\google\zxing\client\android\camera

apk就生成了。

也可以导入到Eclipse后再进行修改。

修改后没有报错，但在运行时出现以下问题

按照网上很多说法都是把

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，我就忘记clean反反复复折腾了好几次
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

但对于我的工程还是会报这个错误，后来还是在网上找到的解决办法，缺少了javase-3.1.0.jar库

生成办法跟core一样D:\zxing\zxing-zxing-3.1.0\javase>mvn -DskipTests -Dgpg.skip=true install
