实施zxing-2.0到我的Android应用 [英] Implement zxing-2.0 into my android app
问题描述
所以我想实现一个进入我的应用程序，但问题是，它不会作为一个单独的应用程序工作，所以美眉evrytime我启动它。我做的事情埃夫里在随后的教程<一个href=\"http://damianflannery.word$p$pss.com/2011/06/13/integrate-zxing-bar$c$c-scanner-into-your-android-app-natively-using-eclipse/\" rel=\"nofollow\">http://damianflannery.word$p$pss.com/2011/06/13/integrate-zxing-bar$c$c-scanner-into-your-android-app-natively-using-eclipse/然而，它在某种程度上是行不通的。所以我tryied启动captureActivity作为应用程序，而不是库，并且当它试图这样做，它崩溃上启动：
So i'm trying to implement that into my app, however the problem is that it doesn't work as a solo application so it crush evrytime i start it. I do evry thing as in followed tutorial http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/ however, it somehow doesn't work. So i tryied to start the captureActivity as application rather than library, and it crashes on start when it tries to do that:
private static final Set<ResultMetadataType> DISPLAYABLE_METADATA_TYPES =
EnumSet.of(ResultMetadataType.ISSUE_NUMBER,
ResultMetadataType.SUGGESTED_PRICE,
ResultMetadataType.ERROR_CORRECTION_LEVEL,
ResultMetadataType.POSSIBLE_COUNTRY);
这导致了我没有正确编译core.jar添加的问题。但是我看不到的地方，我会做一个错误。我在运行核心目录蚂蚁-f，它给了我core.jar添加。任何想法我能做什么？
That leads to the problem that i didn't compile core.jar correctly. However i can't see where would i do a mistake. I run ant -f in core directory, and it gives me core.jar. Any ideas what could i do?

现在我下载了核心从这里 http://mvnrepository.com/artifact /com.google.zxing/core/2.0 ，并用它来偷同样的错误，所以它必须是别的东西......
Now i downloaded the core from here http://mvnrepository.com/artifact/com.google.zxing/core/2.0 and used it and steal same mistake so it must be something else...
推荐答案
转到属性 - > Java构建路径 - >排序和导出
Go to Properties -> Java Build Path -> "Order and Export"
然后责令core.jar添加到第一的位置并选择它！
Then order the core.jar to the first position and select it!
您必须在手术后清理项目。项目 - >清除
you must clean your project after your operation. Project -> clean
这解决了这个问题。我希望这样可以节省别人的时间。
That solves the problem. I hope it saves somebody's time.
