Answer 1

I had the same problem when I first started using ZXing.

You need to make sure you are requesting the correct barcode format when starting the ZXing activity.

When calling (based on the example)

intent.putExtra("SCAN_MODE", "QR_CODE_MODE");

I'm guessing you actually want to use

intent.putExtra("SCAN_MODE", "PRODUCT_MODE");

Ensure that you include the correct barcode formats as per the Intents.java file:

/**
 * By default, sending Scan.ACTION will decode all barcodes that we understand. However it
 * may be useful to limit scanning to certain formats. Use Intent.putExtra(MODE, value) with
 * one of the values below.
 *
 * Setting this is effectively shorthand for setting explicit formats with {@link #FORMATS}.
 * It is overridden by that setting.
 */
public static final String MODE = "SCAN_MODE";

/**
 * Decode only UPC and EAN barcodes. This is the right choice for shopping apps which get
 * prices, reviews, etc. for products.
 */
public static final String PRODUCT_MODE = "PRODUCT_MODE";

/**
 * Decode only 1D barcodes.
 */
public static final String ONE_D_MODE = "ONE_D_MODE";

/**
 * Decode only QR codes.
 */
public static final String QR_CODE_MODE = "QR_CODE_MODE";

/**
 * Decode only Data Matrix codes.
 */
public static final String DATA_MATRIX_MODE = "DATA_MATRIX_MODE";

/**
 * Comma-separated list of formats to scan for. The values must match the names of
 * {@link com.google.zxing.BarcodeFormat}s, e.g. {@link com.google.zxing.BarcodeFormat#EAN_13}.
 * Example: "EAN_13,EAN_8,QR_CODE"
 *
 * This overrides {@link #MODE}.
