Overview
Description
Written by Google, the Google HTTP Client Library for Java is a flexible, efficient, and powerful
Java library for accessing any resource on the web via HTTP. The library has the following
features:
- Pluggable HTTP transport abstraction that allows you to use any low-level library such as
java.net.HttpURLConnection
, Apache HTTP Client, or URL Fetch on Google App Engine.
- Efficient JSON and XML data models for parsing and serialization of HTTP response and request
content. The JSON and XML libraries are also fully pluggable, and they include support for
Jackson
and Android’s GSON libraries for JSON.
The library supports the following Java environments:
- Java 7 or higher
- Android 4.4 (Kit Kat) or higher
- Google App Engine

Beta Features
Features marked with the
@Beta
annotation at the class or method level are subject to change. They
might be modified in any way, or even removed, in any major release. You should not use beta
features if your code is a library itself (that is, if your code is used on the
CLASSPATH
of users
outside your own control).
Deprecated Features
Deprecated non-beta features will be removed eighteen months after the release in which they are
first deprecated. You must fix your usages before this time. If you don’t, any type of breakage
might result, and you are not guaranteed a compilation error.
