Android Couchbase queryViewNamed on a null object reference

Hello I have a big problem. I have implemented logout functionality to my app. When user logouts I delete database and all the replications and then immediately create new database
//delete database
@Override
public void deleteDatabase() {
try {
database.removeChangeListener(this);
manager.close();

            noteCreatedView.delete();
            notesView.delete();
            poiView.delete();
            sessionsView.delete();

            database.delete();
            database = null;
        } catch (CouchbaseLiteException e) {
            e.printStackTrace();
        }
    }

//create database

 @Override
    public void createDatabase(Context context) {
        this.context = context;
        try {
            manager = new Manager(new AndroidContext(context), Manager.DEFAULT_OPTIONS);
            database = manager.getDatabase(COUCHBASE_DB_NAME);
            database.addChangeListener(this);

            noteCreatedView = database.getView(DocNote.KEY_CREATED);
            notesView = database.getView(DocNote.TYPE);
            poiView = database.getView(DocPoi.TYPE);
            sessionsView = database.getView(DocSession.TYPE);

            setCreatedIndexMap();
            setTypeIndex();
            setPoiIndex();
            setSessionsIndex();

            boolean isSimulationDeleted = database.getDocument(DEMO_TRIP_DOC_ID) == null;

couchbaseAnalytics = new CouchbaseAnalyticsImpl(notesView, sessionsView, isSimulationDeleted);
} catch (IOException | CouchbaseLiteException e) {
e.printStackTrace();
Crashlytics.logException(e);
}
}

ant then after user login I immediately call this method

@Override
    public int getNotesCount() {
        ThreadUtils.assertIsWorkerThread();
        Query query = notesView.createQuery();
        try {
            QueryEnumerator result = query.run();
            return result.getCount();
        } catch (CouchbaseLiteException e) {
            e.printStackTrace();
        }
        return 0;
    }

and here QueryEnumerator result = query.run(); I got this crash. Any ideas what I may be doing wrong?

Hi @deividas.aukstakalni,

What kind of crash did you get? Is there an error message?
