MxSession have empty rooms

[london-tokyo]

Hi all!
I can't get rooms\groups.

This is how i create session

HomeServerConnectionConfig hsConfig = new HomeServerConnectionConfig.Builder()
.withHomeServerUri(Uri.parse(BuildConfig.SERVER_URL))
.build();
Credentials credentials = new Credentials();
WellKnown known = new WellKnown();

        WellKnownBaseConfig homeServer = new WellKnownBaseConfig();
        homeServer.baseURL = authCredentials.getHomeServer();

        known.homeServer = homeServer;
        credentials.accessToken = authCredentials.getAccessToken();
        credentials.deviceId = authCredentials.getDeviceId();
        credentials.userId = authCredentials.getUserId();
        credentials.homeServer = authCredentials.getHomeServer();
        credentials.wellKnown = known;
        hsConfig.setCredentials(credentials);

        IMXStore store = new MXMemoryStore(credentials, context);
        MXDataHandler dataHandler = new MXDataHandler(store, credentials);
        hsConfig.setHomeserverUri(Uri.parse(BuildConfig.SERVER_URL));
        mMXSession = new MXSession.Builder(hsConfig, dataHandler, context).build();
        mCredentials = authCredentials;

        mMXSession.startEventStream(authCredentials.getAccessToken());
        if (!mMXSession.getDataHandler().isInitialSyncComplete()) {
            mMXSession.getDataHandler().getStore().open();

And than i tried get rooms like:
Collection summaries = store.getSummaries(); or
Collection list = session.getDataHandler().getStore().getRooms();

Maybe someone has the same issue?
