• https://github.com/square/retrofit public interface GitHubService { @GET("/users/{user}/repos") List listRepos(@Path("user") String user); } GitHubService service = restAdapter.create(GitHubService.class); List repos = service.listRepos("octocat"); 28.06.2013 © MAKING WAVES 17 retrofit 

• https://github.com/square/picasso • Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(i mageView); • Many common pitfalls of image loading on Android are handled automatically by Picasso: – Handling ImageView recycling and download cancelation in an adapter. – Complex image transformations with minimal memory use. – Automatic memory and disk caching. 28.06.2013 © MAKING WAVES 18 Picasso 

• Android Universal Image Loader by nostra13 – Multithread image loading – Possibility of wide tuning ImageLoader's configuration (thread executors, downlaoder, decoder, memory and disc cache, display image options, and others) – Possibility of image caching in memory and/or on device's file sysytem (or SD card) – Possibility to "listen" loading process – Possibility to customize every display image call with separated options – Widget support – Android 2.0+ support 28.06.2013 © MAKING WAVES 19 Other similar libs 

• Volley (https://developers.google.com/events/io/sessions/325304728) – Nice and easy API for executing REST requests; – unifies the mechanism for REST requests by abstracting the "bottom" layer, i.e. you don't care any more about HttpClient or HttpUrlConnection. On lower versions (<= GINGERBREAD) Volley uses AndroidHttpClient and no higher it uses HttpUrlConnection; – it is very fast. In the I/O presentation the guy states that they tested it at Google with several different apps and Volley was clear winner in all categories; – it is extensible -- you can use it as a basis to create your own custom type of requests (and response handling/parsing) 28.06.2013 © MAKING WAVES 20 

//create a stack CardStack stack = new CardStack(); stack.setTitle("title test"); // add 3 cards to stack stack.add(new MyCard("3 cards")); stack.add(new MyCard("3 cards")); stack.add(new MyCard("3 cards")); // add stack to cardView mCardView.addStack(stack); // draw cards mCardView.refresh(); 28.06.2013 © MAKING WAVES 21 Cards UI https://github.com/nadavfima/cardsui-for-android 

UnifiedPreference 28.06.2013 © MAKING WAVES 22 • Easy to use • Takes care of most of the boilerplate code • Use a single pane for phones, or headers and fragments for tablets • Binds preference values to summaries according to Android Design Guidelines • Translated to 50 locales (imported from AOSP internal strings) • Uses ActionBarSherlock (optional) https://github.com/saik0/UnifiedPreference
