Modern techniques for implementing REST clients on Android 4.0 and below – Part 2 -

In the last part of this tutorial I covered how to make REST calls using Loaders and the LoaderManager class. In this part of the tutorial, I will be covering how to make REST calls using Services and the motivations behind this approach. Handling Runtime Changes. To test that your application restarts itself with the application state intact, you should invoke configuration changes (such as changing the screen orientation) while performing various tasks in your application.

Handling Runtime Changes

Your application should be able to restart at any time without loss of user data or state in order to handle events such as configuration changes or when the user receives an incoming phone call and then returns to your application much later after your application process may have been destroyed. To learn how you can restore your activity state, read about the Activity lifecycle. Context, What Context? - by Dave Smith of Double Encore. Context objects are so common, and get passed around so frequently, it can be easy to create a situation you didn’t intend.

Context, What Context? - by Dave Smith of Double Encore

Loading resources, launching a new Activity, obtaining a system service, getting internal file paths, and creating views all require a Context (and that’s not even getting started on the full list!) To accomplish the task. What I’d like to do is provide for you some insights on how Context works alongside some tips that will (hopefully) allow you to leverage it more effectively in your applications. Context Types. AndroidDev people you should follow. Android Fundamentals: Properly Loading Data. The UI thread is a bad place for lengthy operations like loading data.

Android Fundamentals: Properly Loading Data

You never know how long data will take to load, especially if that data is sourced from a content provider or the network. Android 3.0 (Honeycomb) introduced the concept of Loaders and, in particular, the CursorLoader class that offloads the work of loading data on a thread, and keeps the data persistent during short term activity refresh events, such as an orientation change. We'll incorporate the Loader as a new feature in our ongoing tutorial series building a yet-to-be-named tutorial reader application. Android Fundamentals: Properly Loading Data. Services. A Service is an application component that can perform long-running operations in the background and does not provide a user interface.


Another application component can start a service and it will continue to run in the background even if the user switches to another application. Additionally, a component can bind to a service to interact with it and even perform interprocess communication (IPC). For example, a service might handle network transactions, play music, perform file I/O, or interact with a content provider, all from the background. A service can essentially take two forms: Started Bound. Your app idea.

AndroidBootstrap/android-bootstrap. OkHttp. Overview HTTP is the way modern applications network.


Retrofit. Introduction Retrofit turns your REST API into a Java interface. public interface GitHubService { @GET("/users/{user}/repos") List<Repo> listRepos(@Path("user") String user);} The RestAdapter class generates an implementation of the GitHubService interface.


RestAdapter restAdapter = new RestAdapter.Builder() .setEndpoint(" .build(); GitHubService service = restAdapter.create(GitHubService.class); Each call on the generated GitHubService makes an HTTP request to the remote webserver. List<Repo> repos = service.listRepos("octocat"); Use annotations to describe the HTTP request: URL parameter replacement and query parameter support Object conversion to request body (e.g., JSON, protocol buffers) Multipart request body and file upload API Declaration Annotations on the interface methods and its parameters indicate how a request will be handled. Request Method Every method must have an HTTP annotation that provides the request method and relative URL. @GET("/users/list") Android : Volley and Gson tutorial. Android Volley is the new way to make network requests.

It has a lot of advantages : configurable thread pool, request priority, caching, request cancel. AsyncTask is no more needed and this is a good new as AsyncTask is known for its memory leak issues. In this quick step tutorial, i show the piece of source code to make it work with google gson library. Test before If you wish to test before, you can install the application with the following link.

We have been writing our own network manager to deal with http 302 redirect and caching responses, but there are many opensource project that already does these things very well. Saving (and Retrieving) Android Instance State - Part 1 - Intertech Blog. Why do we need to save instance state? Android activities have a lifecycle (for a diagram of this lifecycle see here). As an activity becomes partially hidden (paused) or fully hidden (stopped), possibly even destroyed, your applications need a way to keep valuable state (i.e. data) the activity has obtained (probably from user input) or created even after the activity has gone away.

As an example, an orientation change can cause your activity to be destroyed and removed from memory and then recreated again. Unless you avail yourself to certain state saving mechanisms, any data your activity has at the time of orientation change can be completely lost in this seemingly simple act.

Nlefler/NLFoursquare-Android. Loading Data in the Background. Path/android-priority-jobqueue. Android Components. The CommonsWare Android Components, or CWAC, are open source libraries to help solve various tactical problems with Android development. Most CWAC components are packaged as a tiny JAR file that you can add to your project (e.g., drop it in libs/), requiring at most other CWAC JARs as dependencies. Most are also available as AAR artifacts in a CommonsWare repository, ready for inclusion in your Gradle-based project build scripts. The current supported CWAC components, and their GitHub repositories, are: cwac-adapter: Provides an AdapterWrapper, a simple wrapper class that, by default, delegates all ListAdapter methods to a wrapped ListAdapter. Condesales/easyFoursquare4Android. Android and REST. Loaders. Implementing Loaders (part 3)

This post introduces the Loader<D> class as well as custom Loader implementations. This is the third of a series of posts I will be writing on Loaders and the LoaderManager: First things first, if you haven’t read my previous two posts, I suggest you do so before continuing further. Here is a very brief summary of what this blog has covered so far. Life Before Loaders (part 1) described the flaws of the pre-Honeycomb 3.0 API and its tendency to perform lengthy queries on the main UI thread. These UI-unfriendly APIs resulted in unresponsive applications and were the primary motivation for introducing the Loader and the LoaderManager in Android 3.0.

Handling Runtime Changes. Android: Loaders versus AsyncTask. One of the biggest pieces of Android that I have neglected to learn about would be Loaders. Seeing as it’s time for me to learn it, perhaps I can help you out a bit with it as well. My main interest with the Loader concept is how it melds with the tried and true AsyncTask, and if it’s really better or not.

Demonstrate HTTP caching with OkHttp and Retrofit. RoboSpice-InfoGraphics.png (600×5417) Stephanenicolas/robospice. Android Async HTTP Clients: Volley vs Retrofit - Instructure Tech Blog. We recently released a new version of our mobile app for Android. Although it was a huge improvement from previous installments in terms of features, design, and usability, there was one nagging issue in the back of our minds: speed. There are times when the app isn’t as snappy as we’d like it to be. After some profiling, benchmarks, and common sense, we determined that retrieving data from the API (the networking) was the bottleneck. The Old Way: AsyncTasks As of the latest version, we use the built-in AsyncTasks to retrieve data from Canvas’ servers. This is What Michael Jackson Sounds Like in Quechua.
