The Twitter Kit for Android, supported by Twitter as part of the Fabric developer suite, helps developers create Android applications that integrate various Twitter functionalities. The SDK can be used to implement easy Twitter login, composing tweets, displaying tweets, and authentication all from a 3rd party application. The Twitter Kit includes "TwitterCore" for standard login, "TweetUi," for displaying a user's Twitter stream, "TweetComposer," for composing and posting new tweets, and "Digits," a new way that users can verify with Twitter via their mobile phone number over SMS-based authentication.
Active development on Google Wave, a collaboration tool that used features of email, chat and document sharing, has been shut down. Google announced that the chief reason for discontinuing Wave was the low user adoption. The platform will live on within other Google projects, as well as the many portions of Wave that have been open sourced.
