Answer 1

You do not have the Barcode Scanner app installed, but you are trying to call to it by Intent . That is exactly why you get ActivityNotFoundException . Install Barcode Scanner in your emulator. The latest .apk is at https://github.com/zxing/zxing/releases

You do not need to include other classes from the project. In fact you shouldn't. They are irrelevant.
