Okhttputils

OkHttpUtils is a convenience wrapper for the OkHttp HTTP client that simplifies common networking operations on Android. It provides a straightforward interface for executing GET and POST requests, including sending form parameters and JSON payloads, as well as uploading files via multipart form data and downloading remote files to local storage.

The library distinguishes itself through a set of practical utilities built on top of OkHttp's core architecture. It wraps synchronous calls into an asynchronous callback pattern, includes an interceptor-based logging layer for request and response details, and offers a custom SSL trust manager for handling self-signed or custom certificates. Cookie persistence is handled via an interceptor that saves session and persistent cookies to disk, while file transfers are augmented with progress reporting that tracks upload and download progress as a decimal ratio. Request lifecycle control is provided through tag-based cancellation, allowing active HTTP requests to be grouped and cancelled together.

Additional capabilities include a JSON body serialization helper for POST requests, a multipart form data builder for constructing complex uploads, and the ability to fetch and display remote images as bitmaps. The library also supports configuring HTTPS connections with custom certificates and persisting cookies across application restarts to maintain session state.
