Freshly Cloned Doesn't Show Anything

[Ep0chalypse]

Hi and first off thanks for creating this repository and the accompanying blog posts explaining it! I'm trying to learn rxjava/mvp/content providers and this is great.

I can't seem to get this app to work. On a freshly cloned version the app starts up but does not display anything on the ui. From my limited knowledge of how DP works and MVP it seems the remote datastore is never called. If I manually call getPost() on the AppRemoteDataStore it works properly and fetches data

'AppRemoteDataStore remote = new AppRemoteDataStore();

    remote.getPost().subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Action1<List<Post>>() {
                @Override
                public void call(List<Post> posts) {
                    Log.d(TAG, "MainActivity hack: " + posts.size());
                }
            });`

I'd love to play around with this app more and continue my learning, but I've pretty much hit a wall here and I can't figure out the issue.

I have the same issue, it seems the rx concat is not calling the remote data

I followed also this tutorial some time ago and had a similar problem. After reading about Observables I realized that when using Observable.concat() the next emiting source is called only after the previous one has finished, hence quering the database and returning asRxObservable() gives us a listener to the database that has no end, so .concat never calls the next observable. An easy fix is to replace asRxObservable() with executeAsBlocking() and emit the resulting list using Observable.just().

Hope this helps someone
