title: ZXing doesn't read 1D barcode in Android app
body: <p>I am developing a new application which hopefully will use a barcode reader to scan and find books. I will then use the ISBN information to get more information.</p>
  
  <p>The intents work and I can scan 2d barcodes ok but not the 1d barcodes of books which I know scan fine using the full application. </p>
  
  <p>This is my code. I have tried it without putting the intent extras and it doesn't change anything.</p>
  
  <pre><code>Intent intent = new Intent("com.google.zxing.client.android.SCAN");
  intent.putExtra("SCAN_MODE", "ONE_D_MODE");
  startActivityForResult(intent, 0);
  </code></pre>
  
  <p>Is there something obvious I am missing? The settings in the app also are selected on 1d scanning only.</p>
  
  <p>Thanks</p>
