Android: SqLite database illegal state exception (database is already closed)

I have a helper database object. It is important that I close it, leaving the activity, so I do it. However, when I return to activity, I get a warning about a database request that is already closed. The query does work, but still something is clearly wrong.

My understanding of the Android activity life cycle is not strong, but I would suggest that I need to open the database again in onResume (). This is not true?

Here onResume ():

@Override
protected void onResume() {

super.onResume();

    dbHelper.setInteger(playerID);        
    dbHelper.openDataBase();
    ourCursor = dbHelper.getPlayerSavedQuestions();        
    startManagingCursor(ourCursor);
    adapter = new MyCustomAdapter(ourCursor);
    myListView.setAdapter(adapter);
}

Here is dbHelper.openDataBase ();

    public void openDataBase() throws SQLException {
    String myPath = DATABASE_PATH + DATABASE_NAME;
    dbSqlite = SQLiteDatabase.openDatabase(myPath, null,
            SQLiteDatabase.OPEN_READWRITE);       
}

Here is my logcat:
