+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: +
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 also recovers from problematic + proxy servers and failed SSL handshakes. + +
You can try OkHttp without rewriting your network code. The core module implements
+ the familiar java.net.HttpURLConnection API. And the optional
+ okhttp-apache module implements the Apache HttpClient API.
+
+
OkHttp supports Android 2.2 and above. For Java, the minimum requirement is 1.5.
