I think the issue was by ths following , There're different barcode symbologies that can encode text. The main problem is how much text you want to encode and which apps are you going to use to decode the barcode.
If you're using an URL shortener and you want to stick to a 1D barcode, CODE128 is probably the best choice.

I hope this helps you . I have collection of products in which some product has barcode and some has not. So, I want to show all products which doesn't have any barcode and if any product has barcode then they will be grouped by barcode so that I can show only one.
code :
;WITH cte
AS
(
    SELECT ID, Name, Barcode
    FROM (
        VALUES
        (1, 'ABC', '349377934434'),
        (2, 'DEF', '349377934434'),
        (3, 'XYZ', NULL),
        (4, 'XXX', NULL),
        (5, 'ABC1', '34937'),
        (6, 'DEF1', '34937'),
        (7, 'DEF2', '34937')
    )v(ID, Name, Barcode)
)

SELECT DISTINCT v.ID, v.Name, c.Barcode
FROM cte c
    CROSS APPLY (SELECT TOP 1 ID, Name FROM cte WHERE Barcode = c.Barcode) v
WHERE c.Barcode IS NOT NULL
UNION
SELECT ID, Name, Barcode
FROM cte c
WHERE c.Barcode IS NULL
CREATE TABLE temp(id INT, name VARCHAR(20), barcode VARCHAR(20));
    INSERT INTO temp SELECT 1, 'ABC', '349377934434';
    INSERT INTO temp SELECT 2, 'DEF', '349377934434';
    INSERT INTO temp SELECT 3, 'XYZ', NULL;
    INSERT INTO temp SELECT 4, 'XXX', NULL;
    INSERT INTO temp SELECT 5, 'ABC1', '34937';
    INSERT INTO temp SELECT 6, 'DEF1', '34937';
    INSERT INTO temp SELECT 7, 'XYZ2', '34937';

    SELECT DISTINCT v.ID, v.Name, c.Barcode
    FROM temp c
        INNER JOIN temp v ON v.ID = (SELECT ID FROM temp WHERE Barcode = c.Barcode LIMIT 1)
    WHERE c.Barcode IS NOT NULL
    UNION
    SELECT ID, Name, Barcode
    FROM temp
    WHERE Barcode IS NULL;

    DROP TABLE temp;

Hope that helps I have worked with similar device. When you click on some area where you can edit text, and scan a bar code, will it print it on the field? If yes, then you can use the following snippet inside your Activity:
Override dispatchKeyEvent method. Small sample:
code :
   @Override
    public boolean dispatchKeyEvent(KeyEvent event) {
        if (event.getCharacters() != null && !event.getCharacters().isEmpty())
        //Add more code...
        return super.dispatchKeyEvent(event);

    }
