OkHttp. Overview HTTP is the way modern applications network.
It’s how we exchange data & media. Doing HTTP efficiently makes your stuff load faster and saves bandwidth. OkHttp is an HTTP client that’s efficient by default: HTTP/2 support allows all requests to the same host to share a socket. OkHttp perseveres when the network is troublesome: it will silently recover from common connection problems. Using OkHttp is easy. OkHttp supports Android 2.3 and above. Examples Get a URL This program downloads a URL and print its contents as a string. OkHttpClient client = new OkHttpClient(); String run(String url) throws IOException { Request request = new Request.Builder() .url(url) .build(); Response response = client.newCall(request).execute(); return response.body().string();} Post to a Server This program posts data to a service.

Apache HttpComponents - HttpClient for Android. This project represents an effort to provide an implementation of Apache HttpClient, which can be deployed on Google Android in parallel to the outdated version shipped with the platform while remaining partially API compatible with Apache HttpClient 4.3.
Background Google Android 1.0 was released with a pre-BETA snapshot of Apache HttpClient. To coincide with the first Android release Apache HttpClient 4.0 APIs had to be frozen prematurely, while many of interfaces and internal structures were still not fully worked out. As Apache HttpClient 4.0 was maturing the project was expecting Google to incorporate the latest code improvements into their code tree. Unfortunately it did not happen. Apache HttpClient 4.3 port for Android is intended to remedy the situation by providing official releases compatible with Google Android. Differences with the stock version of Apache HttpClient Compatibility notes Download. Android’s HTTP Clients. [This post is by Jesse Wilson from the Dalvik team.
—Tim Bray] Most network-connected Android apps will use HTTP to send and receive data. Android includes two HTTP clients: HttpURLConnection and Apache HTTP Client. Both support HTTPS, streaming uploads and downloads, configurable timeouts, IPv6 and connection pooling. Apache HTTP Client DefaultHttpClient and its sibling AndroidHttpClient are extensible HTTP clients suitable for web browsers. But the large size of this API makes it difficult for us to improve it without breaking compatibility. HttpURLConnection HttpURLConnection is a general-purpose, lightweight HTTP client suitable for most applications. Prior to Froyo, HttpURLConnection had some frustrating bugs. Private void disableConnectionReuseIfNecessary() { // HTTP connection reuse which was buggy pre-froyo if (Integer.parseInt(Build.VERSION.SDK) < Build.VERSION_CODES.FROYO) { System.setProperty("http.keepAlive", "false"); }} Accept-Encoding: gzip Which client is best?
Android HttpUrlConnection getInputStream throws NullPointerException. Android Asynchronous Http Client. Overview An asynchronous callback-based Http client for Android built on top of Apache’s HttpClient libraries.
All requests are made outside of your app’s main UI thread, but any callback logic will be executed on the same thread as the callback was created using Android’s Handler message passing. Features Make asynchronous HTTP requests, handle responses in anonymous callbacks HTTP requests happen outside the UI thread Requests use a threadpool to cap concurrent resource usage GET/POST params builder (RequestParams) Multipart file uploads with no additional third party libraries Tiny size overhead to your application, only 25kb for everything Automatic smart request retries optimized for spotty mobile connections Automatic gzip response decoding support for super-fast requests Binary file (images etc) downloading with BinaryHttpResponseHandler Built-in response parsing into JSON with JsonHttpResponseHandler Persistent cookie store, saves cookies into your app’s SharedPreferences Instagram.
