zxing QRスキャナが動作しないlollipop 5.1 version

Question

私はアンドロイドアプリケーションでQRスキャナの実装を行っています。それは6.0といくつかの他のOSバージョンで動作しますが、QRスキャナをクリックしてハンドルの意図を得ていないときにクラッシュするロリポップ5.1バージョンでは動作しません。

コード：

 public void aadahrScan() { 
      Intent intent = new Intent("com.google.zxing.client.android.SCAN"); 
      startActivityForResult(intent, 0); 
     } 

    @Override 
     public void onActivityResult(int requestCodeTools, int resultCodeTools, Intent intentTools) { 
      if (requestCodeTools == 0 && intentTools != null) { 
       requestCodeTools(resultCodeTools, intentTools); 
      } 
     } 

Error:

の誰のおかげで、あなたのAndroidManifestにこれを追加、この問題を解決してください、私はカメラに

にアクセスする必要がありますされ、すべての許可を与えたもマニフェストファイルを追加しました：

<activity android:name="com.google.zxing.client.android.CaptureActivity" 
    android:screenOrientation="landscape" 
    android:configChanges="orientation|keyboardHidden" 
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
