First code snippet using rxJava. Retrieves a list of repositories from Github and passes it to a CardsList

FragmentRepos.java

public class FragmentRepos extends DefaultListFragment {
    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        GithubClient client = new GithubClient(true);
        RepoService repoService = client.createService(RepoService.class);
        Observable<List<Repo>> repos = repoService.getRepos("fnk0");
        AppObservable.bindFragment(this, repos);
        repos.subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Action1<List<Repo>>() {
                    @Override
                    public void call(List<Repo> repos) {
                        Collections.sort(repos);
                        ArrayList<Card> cards = new ArrayList<>();
                        for (Repo r : repos) {
                            cards.add(new CardRepo(getActivity(), r));
                        }
                        mCardArrayAdapter = new CardArrayRecyclerViewAdapter(getActivity(), cards);
                        recyclerViewList.setAdapter(mCardArrayAdapter);
                        refreshList();
                        progressWheel.setVisibility(View.GONE);
                    }
                });
    }
