所以我试图在我的应用程序中实现它,但问题是它不能作为一个单独的应用程序工作,所以它在我每次启动它时都会崩溃。我按照以下教程http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/做所有事情,但是,不知何故不起作用。所以我尝试将 captureActivity 作为应用程序而不是库启动,当它尝试这样做时它会在启动时崩溃:
private static final Set<ResultMetadataType> DISPLAYABLE_METADATA_TYPES =
EnumSet.of(ResultMetadataType.ISSUE_NUMBER,
ResultMetadataType.SUGGESTED_PRICE,
ResultMetadataType.ERROR_CORRECTION_LEVEL,
ResultMetadataType.POSSIBLE_COUNTRY);
这导致我没有正确编译 core.jar 的问题。但是我看不出我会在哪里犯错。我在核心目录中运行 ant -f,它给了我 core.jar。有什么想法我能做什么?

现在我从这里http://mvnrepository.com/artifact/com.google.zxing/core/2.0下载了核心并使用它并窃取了同样的错误,所以它必须是别的东西......
