我已將zxing庫集成到我的應用程序以掃描QR碼。正如我按下一個按鈕，啓動斑馬線掃描活動，應用程序崩潰，並給這些下列消息上的logcat，

我無法檢測到什麼實際問題。因此，需要一些幫助來解決問題，以便發現問題所在。

Answer 1

問題是，您已將我們所有android/代碼複製並粘貼到您的項目中，並且不太瞭解您所複製的內容。以這種方式複製我們的應用程序是強烈沮喪。如果您是Android新手，那麼嘗試重複使用我們的代碼可能過於複雜。

1. 刪除您從android/和core/
2. 複製所有的代碼添加android-integration/
3. 實現條碼掃描與3行代碼按http://code.google.com/p/zxing/wiki/ScanningViaIntent

我也面臨着同樣的問題，當我使用的Zxing圖書館和我通過這種技術解決了它

在Manifes中給出啓動器活動的完整路徑科技檔案，如「PacakageName.StartActivity」
