OkHttp is an HTTP client that’s efficient by default:

1.HTTP/2 support allows all requests to the same host to share a socket.
2.Connection pooling reduces request latency (if HTTP/2 isn’t available).
3.Transparent GZIP shrinks download sizes.
4.Response caching avoids the network completely for repeat requests.

Using OkHttp is easy. Its request/response API is designed with fluent builders and immutability.
It supports both synchronous blocking calls and async calls with callbacks.

OkHttp works on Android 5.0+ (API level 21+) and Java 8+.

OkHttp depends on Okio for high-performance I/O and the Kotlin standard library.
Both are small libraries with strong backward-compatibility.

We highly recommend you keep OkHttp up-to-date. As with auto-updating web browsers,
staying current with HTTPS clients is an important defense against potential security problems.
We track the dynamic TLS ecosystem and adjust OkHttp to improve connectivity and security.
