ListView problem. Cursor gets closed

Software Development and Hacking
I am using ListView to display a small list. I know it’s on the main thread, but this is not a problem. It used to run under earlier API levels but gives a problem under 27.

Code:

    private void populateListViewFromDB() {

        Cursor cursor = myDb.getAllLogRows();

        // Allow activity to manage lifetime of the cursor.
        // DEPRECATED! Runs on the UI thread, OK for small/short queries.
        startManagingCursor(cursor);

        // Setup mapping from cursor to view fields:
        String[] fromFieldNames = new String[]{DBAdapter.KEY_LOG_ID, DBAdapter.KEY_LOG_DATE, DBAdapter.KEY_LOG_TIME, DBAdapter.KEY_LOG_LOG};

        int[] toViewIDs = new int[]{R.id.item_id, R.id.item_date, R.id.item_time, R.id.item_log};

        // Create adapter to many columns of the DB onto elements in the UI.
        SimpleCursorAdapter myCursorAdapter = new SimpleCursorAdapter(this,    // Context
                R.layout.log_item_layout,                                              // Row layout template
                cursor,                                                                // cursor (set of DB records to map)
                fromFieldNames,                                                        // DB Column names
                toViewIDs);                                                            // View IDs to put information in

        // Set the adapter for the list view
        ListView myList = (ListView) findViewById(R.id.id_log_list);
        myList.setAdapter(myCursorAdapter);
    }


On executing the last line (myList.setAdaper…) it bombs out with:

Can anyone please tell me what is happening to the cursor?
