Android二維碼開源項目zxing編譯

編輯：關於Android編程

ZXing是一個開放源碼的，用Java實現的多種格式的1D/2D條碼圖像處理庫，它包含了聯系到其他語言的端口。Zxing可以實現使用手機的內置的攝像頭完成條形碼的掃描及解碼。該項目可實現的條形碼編碼和解碼。

目前支持以下格式：

\

zxing官網說明：https://github.com/zxing/zxing/wiki/Getting-Started-Developing

源碼下載：https://github.com/zxing/zxing

我下載的是releases版本：https://github.com/zxing/zxing/releases<喎?/kf/ware/vc/" target="_blank" class="keylink">vcD4KPHA+PGltZyBzcmM9"/uploadfile/Collfiles/20140725/20140725091720126.png" alt="\">

需要的工具：

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

\

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

\

我下載的是Windows版的，如果是Linux需要下載Linux版，這裡只嘗試Windows下編譯。

下載後在合適的目錄下解壓，將bin目錄添加到環境變量，跟JDK方法一樣。

這裡只配置下ant的環境變量

1.我的電腦右鍵

\

2.點擊“屬性”

\

3.點擊“環境變量”

\

4.點擊“編輯”

\

添加解壓後的bin到Path就可以了，記得用;結束，驗證下

\

配置編譯

確保你已經有了java運行環境，如JAVA_HOME、CLASSPATH、PATH都配置好了

進入到zxing-zxing-3.1.0\android目錄，輸入命令：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>

但提示出錯了，需要我們提供一個target，輸入命令：android list targets

根據輸出的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.

這裡報了兩個問題

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

修改ses-sdk android:minSdkVersion="14"就可以了。

二、是JDK版本的問題

修改：E:\Android\adt-bundle-windows-x86\sdk\tools\ant\build.xml
改成
前面的錯誤沒有了，但出現新的問題

apk就生成了。

也可以導入到Eclipse後再進行修改。

修改後沒有報錯，但在運行時出現以下問題

按照網上很多說法都是把

到處搜索解決方案，終於在google的幫助下解決了。
在eclipse中 Properties -> Java Build Path -> "Order and Export"
在Order and Export選項卡中將core.jar提前到第一位 並選中它
然後clean你的工程,這一步非常重要，別忘記了，我就忘記clean反反復復折騰了好幾次
重新編譯運行就可以了

估計是在core.jar之前的包裡已經有了同名的class所以編譯之後產生的apk運行時找不到真正的引用。而且這個包也需要被同時發布到程序中去

但對於我的工程還是會報這個錯誤，後來還是在網上找到的解決辦法，缺少了javase-3.1.0.jar庫

生成辦法跟core一樣D:\zxing\zxing-zxing-3.1.0\javase>mvn -DskipTests -Dgpg.skip=true install
