An HTTP+HTTP/2 client for Android and Java applications.
OkHttp
An HTTP & SPDY client for Android and Java applications. For more information see the website and the wiki.
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 and SPDY support allows all requests to the same host to share a socket.
- Connection pooling reduces request latency (if SPDY isn’t available).
- Transparent GZIP shrinks download sizes.
- Response caching avoids the network completely for repeat requests.
OkHttp perseveres when the network is troublesome: it will silently recover from common connection problems. If your service has multiple IP addresses OkHttp will attempt alternate addresses if the first connect fails. This is necessary for IPv4+IPv6 and for services hosted in redundant data centers. OkHttp initiates new connections with modern TLS features (SNI, ALPN), and falls back to TLS 1.0 if the handshake fails.
Using OkHttp is easy. Its 2.0 API is designed with fluent builders and immutability. It supports both synchronous blocking calls and async calls with callbacks.
You can try out OkHttp without rewriting your network code. The okhttp-urlconnection module implements the familiar java.net.HttpURLConnection API and the okhttp-apache module implements the Apache HttpClient API.
OkHttp supports Android 2.3 and above. For Java, the minimum requirement is 1.7.
