I've met these articles:

  • Restful API service
  • Java REST client API for Android

And that lead me to this Google I/O 2010 video about REST client applications

Since now, I've been creating REST component as static component in my Application controller class.

From now, I think, I should change the pattern. Somebody pointed out that Google IOSched application is great sample of how to write REST clients on Android. Somebody else told that this ways is too overcomplicated.

So, can anybody please show us what is the best practice? In short and simple way. The IOSched application is too complex for sample use-case.

Easiest Way To Make REST API calls on Android Beginner Friendly , In this post i will teach you how to make REST API Calls(GET,POST,… and then sanitized the response before feeding it into a JSON parser. Source code for an Android AsyncTask (REST client) example. /** * Android RestTask (REST) from the Android Recipes book. if you wanted to see an Android

Android REST client, Sample?, EDIT 2 (October 2017):. It is 2017. Just use Retrofit. There is almost no reason to use anything else. EDIT: The original answer is more than a� REST APIs are used by your server. If you only make REST API calls from a server that you manage and use to support your app, see Enable Server-Side API Access for instructions on how to authorize on your Android client. Use Google APIs for Android.

Never use AsynTask to perform network request or whatever that need to be persisted. Async Task are strongly tied to your activity and if the user change the orientation of the screen since the App is re created the AsyncTask will be stopped.

I suggest you to use Service pattern with Intent Service and ResultReceiver. Take a look to RESTDroid. It's a library that allows you to perform any kind of REST request asynchronously and notify your UI with Request Listeners implementing the Virgil Dobjanschi's service pattern.

REST API on Android Made Simple or: How I Learned to Stop , It is not an in-depth Retrofit or RxJava tutorial. Rather, it's a short and simple guide on dealing with an API request using said two libraries in� RestClientTemplate is a skeleton Android project that makes writing Android apps sourced from OAuth JSON REST APIs as easy as possible. This skeleton project combines the best libraries and structure to enable quick development of rich API clients.

There is another library with much cleaner API and type-safe data. https://github.com/kodart/Httpzoid

Here is a simple usage example

Http http = HttpFactory.create(context);
http.post("http://example.com/users")
    .data(new User("John"))
    .execute();

Or more complex with callbacks

Http http = HttpFactory.create(context);
http.post("http://example.com/users")
    .data(new User("John"))
    .handler(new ResponseHandler<Void>() {
        @Override
        public void success(Void ignore, HttpResponse response) {
        }

        @Override
        public void error(String message, HttpResponse response) {
        }

        @Override
        public void failure(NetworkError error) {
        }

        @Override
        public void complete() {
        }
    }).execute();

It is fresh new, but looks very promising.

In this example the android client will send some string to server which is reversed and sent back to the android client. Android Restful Web Service Client Example. 1. Create a new android project with package name com.androidrestfullwebservice. 2.

There is plenty of libraries out there and I'm using this one: https://github.com/nerde/rest-resource. This was created by me, and, as you can see in the documentation, it's way cleaner and simpler than the other ones. It's not focused on Android, but I'm using in it and it's working pretty well.

It supports HTTP Basic Auth. It does the dirty job of serializing and deserializing JSON objects. You will like it, specially if your API is Rails like.

Android From Scratch: Using REST APIs - Code Tuts, In this tutorial, I'm going to show you how to use the classes and methods Making use of a REST API obviously involves using the Internet. Retrofit is a REST Client for Java and Android. It makes it relatively easy to retrieve and upload JSON (or other structured data) via a REST based webservice. In Retrofit you configure which converter is used for the data serialization. Typically for JSON you use GSon, but you can add custom converters to process XML or other protocols.

Authorizing and Using REST APIs, compile 'com.google.api-client:google-api-client-android:1.22.0' // Change to the API you want to access: // Below is just an example for People REST API� Retrofit Android. Retrofit is type-safe REST client for Android and Java which aims to make it easier to consume RESTful web services. We’ll not go into the details of Retrofit 1.x versions and jump onto Retrofit 2 directly which has a lot of new features and a changed internal API compared to the previous versions.

Send a simple request, Here is an example that uses a string value for the tag: Define your tag and add it to your requests. Kotlin Java� Combine that with tedious work of manually dealing with any kind of RESTful API, and you soon find yourself in a hell made of disjointed code fragments, repeated loops and confusing callbacks. This article will show you, step-by-step, how to make a simple API call on Android the easy way — using 3rd party libraries.

  • Hello, Generally I develop separate package for web service named "ws", I have generalize class named "WebServicUtils.java". WebServiceUtils.java class has methods to access web service. I am not sure about my technique is best or not but It is reusable every time I copy my ws package in Android Application, Let me know if you want to know more about my technique.
  • I don't think the youtube commenter has a better alternative. We have to work within Android's APIs, even if they are often insanely over-complicated and verbose nonsense.
  • As a side note, Mechanoid, an open-source eclipse plugin for Android can generate JSON-REST clients using a simple DSL, a guide on how to use it can be found here robotoworks.com/mechanoid-plugin/service-client-dsl (I am the author of this plugin, sorry for the shameless plug!)
  • This might be very helpful for people learning Android REST client implementation. Dobjanschi's presentation transcribed into a PDF: drive.google.com/file/d/0B2dn_3573C3RdlVpU2JBWXdSb3c/…
  • I like this answer more due to examples of quite nice code. Thanks
  • Probably worth nothing, this doesn't really follow a proper RESTful MVC pattern, as described by Virgil Dobjanschi. You would need to incorporate a full ContentProvider layer, which uses a SQLite database which the app directly uses. Otherwise, this is a good, lightweight REST client for Android.
  • One small thing, you'll need to call execute on those Get/PostTask's
  • This is really great. How would I make the GetResponseCallback more generic, so it doesn't pass only a Profile back, or would you suggest making a seperate GetResponseCallback for each type of data from the API?
  • @MichaelHerbig Yes, there are ways to make GetResponseCallback more generic. The one I prefer is to use a marker interface : Like interface IGetResopnse{} to denote all classes that could be responses. Then, I have class Profile implements IGetResponse etc. Finally, make GetResponseCallback generic with IGetResponse as the upper bound : public abstract class GetResponseCallback<? extends IGetResponse>.
  • The O'Reilly book, Programming Android, features a full implementation of Dobjanschi's RESTful MVC pattern (chapters 12-13).
  • Thanks for the hint: I found this statement on Amazon: "Chapter 12 and 13 deal with content providers. The extensive treatment of content providers with example code and a sample application provided me several new insights in how this technology works, and how it can be used in real programming situations. The content provider framework for storing and referencing data using URIs is one of the novel features of the Android operating system. Great work in explaining the technology step by step!"
  • The code is on github.com/bmeike/ProgrammingAndroid2Examples (but chapters are missing, you can find them in the first edition code github.com/bmeike/ProgrammingAndroidExamples)
  • Has anybody been able to get this code running on ICS+? The todo file under the FinchVideo example succinctly states "- Crashes under ICS". I was somewhat disappointed after buying the book to discover the code examples are broken...
  • It seems to be running on AsyncTask, what is not good for long running requests and switches between activities, because AsyncTask will be killed when Activity exits.
