雖然eclipse SDK的獨立qr掃描儀爲Android但在執行時得到一個運行時錯誤

Question

我想創建一個應用程序在eclipse中使用sdk，它有一個獨立的qr掃描儀。我遵循一個非常好的教程來合併zxing並複製所有相關庫等，但是當涉及到在設備上運行掃描器時，我不斷收到錯誤「不幸的是，項目名稱已停止工作」。 我是全新的創建應用程序，沒有詞彙來理解錯誤和正確。我想這是與清單有問題....

這是我的清單

     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

    public void scanNow(View view){ 
     Intent intent = new Intent("com.google.zxing.client.android.SCAN"); 
     intent.putExtra("com.google.zxing.client.android.SCAN.SCAN_MODE", "QR_CODE_MODE"); 
     startActivityForResult(intent, 0); 

    } 

    public void onActivityResult(int requestCode, int resultCode, Intent intent){ 
    if (requestCode == 0){ 
     if (resultCode == RESULT_OK){ 
       String contents = intent.getStringExtra("SCAN_RESULT"); 
       String format = intent.getStringExtra("SCAN_RESULT_FORMAT"); 
       Log.i("xZing", "contents: "+contents+" format: "+format); 
       // Handle successful scan   
       //else if (resultCode == RESULT_CANCELED) 
       // Handle cancel Log.i("xZing", "Cancelled"); 
      } 
     } 
    } 
} 

如果任何人都可以在正確的方向指向我，我將永遠感激

乾杯

您需要安裝條碼掃描儀。如果您使用過提供的IntentIntegrator，則可以爲您完成：https://code.google.com/p/zxing/wiki/ScanningViaIntent並正確處理。您不需要清單條目來使用相機等。
