As part of the continued development of the Ubuntu platform, the Content Hub has gained the ability to share links (and soon text) as a content type, just as it has been able to share images and other file-based content in the past. This allows applications to more easily, and more consistently, share things to a user’s social media accounts.
Thanks to the collaborative work going on between the Content Hub and the Ubuntu Webapps developers, it is now possible for remote websites to be packaged with local user scripts that provide deep integration with our platform services. One of the first to take advantage of this is the Facebook webapp, which while displaying remote content via a web browser wrapper, is also a Content Hub importer. This means that when you go to share an image from the Gallery app, the Facebook webapp is displayed as an optional sharing target for that image. If you select it, it will use the Facebook web interface to upload that image to your timeline, without having to go through the separate Friends API.
This work not only brings the social sharing user experience inline with the rest of the system’s content sharing experience, it also provide a much simpler API for application developers to use for accomplishing the same thing. As a result, the Friends API is being deprecated in favor of the new Content Hub functionality.
What it means for App Devs
Because this is an API change, there are things that you as an app developer need to be aware of. First, though the API is being deprecated immediately, it is not being removed from the device images until after the release of 14.10, which will continue to support the ubuntu-sdk-14.04 framework which included the Friends API. The API will not be included in the final ubuntu-sdk-14.10 framework, or any new 14.10-dev frameworks after -dev2.
After the 14.10 release in October, when device images start to build for utopic+1, the ubuntu-sdk-14.04 framework will no longer be on the images. So if you haven’t updated your Click package by then to use the ubuntu-sdk-14.10 framework, it won’t be available to install on devices with the new image. If you are not using the Friends API, this would simply be a matter of changing your package metadata to the new framework version. For new apps, it will default to the newer version to begin with, so you shouldn’t have to do anything.Read more
