java. Lang.illegalstateexception: cannot read line 0 col 0 from cursorwindow

I need to get all the data from the table. I use the following code to perform the same operation in the SQLite dbhelper class:

public Cursor getData() {
        sqliteDatabase db = this.getWritableDatabase();
        Cursor res = db.rawQuery("select * from " + PRODUCT_DETAILS_TABLE,null);
        return res;
    }

Now I use the cursor to get data in my activity in the following ways:

public HashMap<String,ArrayList<CartModal>> getDatas() {

            map = new HashMap<String,ArrayList<CartModal>>();
            stored_data = new ArrayList<CartModal>();
            Cursor cartdb = dbHelper.getData();
            if (cartdb != null && cartdb.getCount() > 0) {
                if (cartdb.moveToFirst()) {
                    do {
                        String mloggedinuser = cartdb.getString(0);
                        String mname = cartdb.getString(1);
                        String email = cartdb.getString(2);
                        String mobile = cartdb.getString(3);
                        String about = cartdb.getString(4);
                        String pid = cartdb.getString(5);
                        String refnum = cartdb.getString(6);
                        String size = cartdb.getString(7);
                        String weight = cartdb.getString(8);
                        String price = cartdb.getString(9);
                        String catid = cartdb.getString(10);
                        String image = cartdb.getString(11);

                        CartModal cartarray = new CartModal(mloggedinuser,mname,email,mobile,about,pid,refnum,size,weight,price,catid,image);
                        stored_data.add(cartarray);
                        keys = mname;
                        map.put(mname,stored_data);
                    } while (cartdb.moveToPosition(stored_data.size()));
                    cartdb.close();
                }
            }
            return map;
        }

When I run the above program, I receive the following error:

E/AndroidRuntime: FATAL EXCEPTION: main

I have experienced many solutions in stackoverflow (Android Java. Lang. IllegalStateException: couldn't read row 0, col 0 from cursorwindow), but no one has helped me solve this problem Please suggest me a solution

Solution

What I'm doing is right But the problem is, I'm saving an image in DB as Base64 encoded string Although the data is obtained, it shows an illegal exception When I delete the image, it works perfectly
