i want to fetch the sqlite database then according to the date existing in it i want to create a notification.. but the system display an error

Question 1

After iterating through the whole cursor with getAllRows()

you try to get one more element:

c.getString(c.getColumnIndex("match_date"))
                                + (c.getColumnIndex("team1"))
                                + (c.getColumnIndex("team2"))
                                + (c.getColumnIndex("flags1"))
                                + (c.getColumnIndex("flags2"))).build();

This won't work. You will have to remove these lines.

try following:

        NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(myNotificationId , notification);
    }

}

Question 2

It crashes because you try to access a slot outside of the cursor bounds:

Caused by: android.database.CursorIndexOutOfBoundsException: Index 48 requested, with a size of 48

Instead of

while (!c.isAfterLast()) {
 [...]
 c.moveToNext();
}

use

do {
  [...]                 
} while (cursor.moveToNext());
