        String latitude = lat.getText().toString();

        Intent i = new Intent("com.google.zxing.client.android.ENCODE");
        i.putExtra("ENCODE_TYPE", Contents.Type.LOCATION);
        i.putExtra("ENCODE_DATA", data);

        int smallerDimension = width < height ? width : height;
        smallerDimension = smallerDimension * 3 / 4;

        // Encode with a QR Code image
        QRCodeEncoder qrCodeEncoder = new QRCodeEncoder(null, data,
                Contents.Type.LOCATION, BarcodeFormat.QR_CODE.toString(),
                smallerDimension);

        try {
            Bitmap bitmap = qrCodeEncoder.encodeAsBitmap();
            ImageView myImage = (ImageView) findViewById(R.id.locQRCode);
            myImage.setImageBitmap(bitmap);

        } catch (WriterException e) {
            e.printStackTrace();
        }
        break;

No. I am testing it on emulator. I generated the QR codes for URL,Text,SMS without ZXing scanner installed. I only face a problem with multiple fields data — user3541112, Jul 18 '14 at 10:26
check this out https://github.com/zxing/zxing/tree/master/android/src/com/google/zxing/client/android/encode — user3541112, Jul 18 '14 at 10:27
And I assume you have included that? If so, then I guess it is a problem with the include. — MalaKa, Jul 18 '14 at 10:28

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.
