Where possible, Web API uses appropriate HTTP verbs for each action: MethodĬhanges and/or replaces resources or collections Data resources are accessed via standard HTTPS requests in UTF-8 format to an API endpoint.

The Spotify Web API is based on REST principles. Authorization is via the Spotify Accounts service.

To access private data through the Web API, such as user profiles and playlists, an application must get the user’s permission to access the data. The API provides a set of endpoints, each with its own unique path. Such access is enabled through selective authorization, by the user. Web API also provides access to user related data, like playlists and music that the user saves in the Your Music library. Note: By using Spotify developer tools, you accept the Spotify Developer Terms of Service.īased on simple REST principles, the Spotify Web API endpoints return JSON metadata about music artists, albums, and tracks, directly from the Spotify Data Catalogue.

Public static JSONObject requestWebService(String serviceUrl) else if (statusCode != HttpURLConnection. This is how you get it running with HttpUrlConnection including place holders for some basic error handling: Also check David Chandler’s BasicHttpClient which he considers as simpler to use because it already implements all basic operations such as URL encoding, exception handling and reading the input stream.

If you still want to use Apache’s HTTP client, I recommend to have a look at their tutorial and how to set up a more stable client in your App.

According to the Android developers, HttpUrlConnection should be preferred due to more speed and less energy consumption. You will see later what that means.Īndroid provides already two APIs with that you can send requests to web servers and handle their responses: Apache HTTP Client and HttpUrlConnection. James Clark compared XML and JSON in more detail and pointed out why also I considered to use JSON for my own web services: “By contrast with JSON, especially with a dynamic programming language, you can get a reasonable in-memory representation just by calling a library function”. The syntax is the same like defining JavaScript objects as it is specified in ECMAScript (3rd edition). Some people consider JSON also as more leightweight and easier to read than XML. The advantage of JSON, compared to XML, is the ability to not only provide primitive types, such as strings or numbers, but also objects and arrays. JSON is a specified format for the exchange of structured data.

Update your manifest XML file so that it registers the permission, like: Well, your App will need to connect to the internet in order to request your web services.

This little turorial shows how you send HTTP requests, parse JSON string responses and display the results in a ListActivity, showing a progress dialog while loading. I am sharing my findings of how to implement an Android client for services implemented according to the Representational State Transfer (REST) approach. Web services make it easy for mobile devices to communicate with applications running on a web or application server.
