Answer 1

Here is an example how I manage to decode 1D Barcode and 2d QR Codes using Zxing libraryin Android.

QR DECODE

     Intent intent = new Intent("com.google.zxing.client.android.SCAN");
     intent.putExtra("SCAN_MODE", "QR_CODE_MODE");  
     startActivityForResult(intent, REQUEST_BARCODE);

     Toast toast = Toast.makeText(this, "Start scanning QR code", Toast.LENGTH_SHORT);
     toast.show();

BARCODE DECODE

     Intent intent = new Intent("com.google.zxing.client.android.SCAN");
     intent.putExtra("SCAN_MODE", "PRODUCT_MODE");  
     startActivityForResult(intent, REQUEST_BARCODE);

     Toast toast = Toast.makeText(this, "Start scanning Barcode", Toast.LENGTH_SHORT);
     toast.show();

This code is Working on Android Samsung Galaxy S (Version 2.2). If you want to check different Scan modes check this link: Zxing Intents.java
