This unofficial Java library is for Android developers interested in working with App.net. Although the library is still being developed, it currently supports most of App.net's APIs like: post and user endpoints, message and channel endpoints, file creation and retrieval endpoints, and place search. The library is also set up to be used with Android Studio.
Another day, another API... Keeping on top of all the APIs that have been made public to support the plethora of web services that are available these days can be a full time job. Yahoo thought so too, and so they created the Yahoo Query Language (YQL), which provides access to hundreds of web services with a single SQL like syntax. And now YQL supports Google Buzz.
