An image loading and caching library for Android focused on smooth scrolling

Android library for using the Honeycomb (Android 3.0) animation API on all versions of the platform back to 1.0! Animation prior to Honeycomb was very limited in what it could accomplish so in Android 3.x a new API was written. With only a change in imports, we are able to use a large subset of the new-style animation with exactly the same API. This library also includes support for animating rotation, translation, alpha, and scale on platforms prior to Honeycomb!

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. Connection pooling reduces request latency (if HTTP/2 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 supports modern TLS features (TLS 1.3, ALPN, certificate pinning). It can be configured to fall back for broad connectivity. 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.
