startActivityForResult( i,REQUEST_CODE_QR_SCAN);
}

And catch the scan result:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if(resultCode != Activity.RESULT_OK)
    {
        Log.d(LOGTAG,"COULD NOT GET A GOOD RESULT.");
        if(data==null)
            return;
        //Getting the passed result
        String result = data.getStringExtra("com.blikoon.qrcodescanner.error_decoding_image");
        if( result!=null)
        {
            AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
            alertDialog.setTitle("Scan Error");
            alertDialog.setMessage("QR Code could not be scanned");
            alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            dialog.dismiss();
                        }
                    });
            alertDialog.show();
        }
        return;

    }
    if(requestCode == REQUEST_CODE_QR_SCAN)
    {
        if(data==null)
            return;
        //Getting the passed result
        String result = data.getStringExtra("com.blikoon.qrcodescanner.got_qr_scan_relult");
        Log.d(LOGTAG,"Have scan result in your app activity :"+ result);
        AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
        alertDialog.setTitle("Scan result");
        alertDialog.setMessage(result);
        alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                });
