        return (database.rawQuery("SELECT " + SQLiteHelper.product_id
                + " as _id,"

Solution

return (database.rawQuery("SELECT " + SQLiteHelper.product_id
                + " as _id," 
                + SQLiteHelper.productName + " ," +SQLiteHelper.productDesp
                + "," + SQLiteHelper.productQtty + ","
                +SQLiteHelper.product_CategoryF+" FROM " 
                + SQLiteHelper.productTable+"  WHERE "
                + SQLiteHelper.productName +" LIKE '"+id+"%'",null));

Answer 1

You don’t need to form your SQL like that. rawQuery makes it very easy to bind arguments.

rawQuery("SELECT ? as _id, ?, ?, ?, ? FROM ? WHERE ? LIKE 'id%'", new String[] {SQLiteHelper.product_id, SQLiteHelper.productName, SQLiteHelper.productDesp, SQLiteHelper.productQtty, SQLiteHelper.product_CategoryF, SQLiteHelper.productTable, SQLiteHelper.productName});

As far as your code is concerned, notice ,"+ on your CategoryF line should be +",

    return (database.rawQuery("SELECT " + SQLiteHelper.product_id
            + " as _id," 
            + SQLiteHelper.productName + " ," +SQLiteHelper.productDesp
            + "," + SQLiteHelper.productQtty + ","
            ,"+SQLiteHelper.product_CategoryF+" FROM " 
            + SQLiteHelper.productTable+"  WHERE "
            + SQLiteHelper.productName +" LIKE 'id%'",null));
