|Today we’ll be looking at the Google APIs Client Library for Java. The API is provided by Google, and is a flexible, efficient, and powerful Java client library for accessing any HTTP-based API’s on the web. According to Google, it is the recommended library for accessing Google API’s based on REST or JSON-RPC. One of the nice things about this library is that it fully supports the Android environment out of the box. So we’ll focus on those features in this article.
To avoid confusion, Google offers the following APIs (the first one being the topic of this post, and compatible with the Android platform) :
Unfortunately, there are no samples available that perform the OAuth dance in Android using this library, so I thought I’d write one myself. The code for this article can be found in the AndroidOauthGoogleApiJavaClient repository

Important note : As an update to this article, I’ve prepared a new post entitled Improved Twitter OAuth for Android focussing on a more simple Oauth / Android experience, and using the Google APIs Client Library for Java.
The goal of this article is to get twitter integration up & running from your Android app in 30 minutes. The guide will show you how to
- setup a twitter test account
- register a twitter application
- authenticate the user in your Android application.
- have the user send tweets from your Android application.
This guide is accompanied by a sample application that’s available in Github in the AndroidTwitterSample repository. To import this project in Eclipse, I suggest using the EGit plugin that can be installed via the Main P2 Repository located at http://download.eclipse.org/egit/updates.
Before running this project, make sure you change the com.ecs.android.sample.twitter.Constants file to include your consumer key and consumer secret. (see subsequent section).
Once you have sample application up & running, you can copy the relevant classes into your projects to have Twitter up & running.
Twitter uses the OAuth protocol to authorize your android application to send tweets on behalf of the end-user. The end-user will need to authenticate against Twitter (meaning that your application will not capture the twitter username / password). Once the user has authorized access, you’ll be able to send tweets on behalf of the user. We’ll use signpost library to handle the OAuth communication, and the Twitter4J library to handle the Twitter specific interactions (sending tweets).
