• Android二维码开源项目zxing编译


    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:UsersxiangDesktop estapache-ant-1.9.4-binapache-ant-1.9.4in;

    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-masterandroid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:UsersxiangDesktop	estzxing-masterandroid>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

    根据输出的ID,加上target,命令:android update project --target 2 --path .

    C:UsersxiangDesktop	estzxing-masterandroid>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:UsersxiangDesktop	estzxing-masterandroiduild.xml
    Added file C:UsersxiangDesktop	estzxing-masterandroidproguard-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-mastercore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-masterandroid里输入ant debug

    C:UsersxiangDesktop	estzxing-masterandroid>

    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_64-20130917sdk oolsantuild.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:UsersxiangDesktop estzxing-masterandroidsrccomgooglezxingclientandroidcamera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:UsersxiangDesktop estzxing-masterjavase>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

    完整正常运行源码如下:
