## What it is
Google's flexible and efficient Java library for making HTTP requests to any resource on the web. It features a pluggable transport abstraction and pluggable JSON/XML data models for parsing and serializing request and response content.

## Use cases
- make http requests from java
- call rest apis from an android app
- parse json http responses in java
- swap http transport implementations like apache http client or urlconnection
- build google api client libraries on a common http layer
- serialize request bodies as json or xml

## When to choose
- you need a lightweight, pluggable HTTP client for Java 8+ or Android
- you are building on Google's API or OAuth client libraries for Java
- you want pluggable JSON/XML serialization with Jackson or GSON support
- you target Google App Engine and need URL Fetch transport support

## When to avoid
- you prefer a modern idiomatic client with built-in reactive or async-first APIs
- you are not on the JVM (e.g., Python, Go, Node.js projects)
- you need advanced features like built-in retry policies, circuit breaking, or service discovery out of the box
- you want a non-Google-maintained community-driven library

## Facets
- artifact type: library
