Android ZXing集成错误

Question

我是学生，作为我在学校的Android项目的一部分，我需要包含一个条形码应用程序。我清楚地遵循

http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/

给整合斑马线指令。我在3班，CaptureActivityHandler，DecodeHandler和SearchBookContentsActivity，这是由改变的switch-case语句的if-else解决有错误如下：

if(message.what==R.id.decode){ 
     decode((byte[]) message.obj, message.arg1, message.arg2); 
    } 
    else if(message.what==R.id.quit){ 
     running = false; 
     Looper.myLooper().quit(); 
    } 

在我的应用程序，在按下一个按钮，条形码扫描器意图应该开始。但是我只收到一个错误，说我的应用程序已经停止。 logcat消息如下：

有人可以帮我吗？我已经通过StackOverflow上的许多帖子，但无法找到答案。

Answer 1

如果你真的要嵌入的斑马线，而不是它的意图整合，我建议使用开箱库，你可以找到here: https://github.com/kennydude/zxing-lib

正如马克建议，最常用的方法是整合与他们的应用程序的意图。

Answer 2

您需要按照一步链接

http://www.androidaz.com/development/zxing-qr-reader-direct-integration

给出你可以从

http://repo1.maven.org/maven2/com/google/zxing/core/2.2/

以上是为我工作的下载core.jar添加，如果你的程序仍然崩溃，只需将core-2.2.jar放在libs中并清理你的项目
