Unable to open database file error on using subseq

I have the following code, the first cursor object works fine, but when i do another query and assign it to the flightCursor, it gives the error.

Cursor cursor = database.query( CityAndAirportsTable.notificationsTable, new String[] { CityAndAirportsTable.notifyFlightId },
                null, null, null, null, "Id DESC" );
        cursor.moveToFirst();
        while( !cursor.isAfterLast() ){
            String id = String.valueOf( cursor.getInt( 0 ) );
            Cursor flightCursor = database.query( CityAndAirportsTable.flightTable, new String[] { CityAndAirportsTable.fromDestinationCode,
            CityAndAirportsTable.toDestinationCode, CityAndAirportsTable.currentPrice }, CityAndAirportsTable.flightId + "=" + id,
                    null, null, null, null );
}

Here in the flightCursor = database.query, i get the error.

There are similar question on stackoverflow, but in my case the first query works but the second one fails.

Close your cursor when you're done with it! I think you've just got too many cursor objects open

Cursor cursor = database.query( CityAndAirportsTable.notificationsTable, new String[] { CityAndAirportsTable.notifyFlightId },
                null, null, null, null, "Id DESC" );
cursor.moveToFirst();
while( !cursor.isAfterLast() ){
  String id = String.valueOf( cursor.getInt( 0 ) );
  Cursor flightCursor = database.query(
    CityAndAirportsTable.flightTable,
    new String[] { CityAndAirportsTable.fromDestinationCode,
      CityAndAirportsTable.toDestinationCode,
      CityAndAirportsTable.currentPrice },
    CityAndAirportsTable.flightId + "=" + id,
    null, null, null, null );

  /* Close the cursor here! */
  flightCursor.close();
  /* ---------------------- */
}

Hopefully this fixes your issue
