The update, the biggest for the Android toolkit so far, comes weeks after the social network gave iOS developers a similar boost. It allows developers to create apps that functions more as a built-in part of the operating system rather than as an afterthought.
These features include a friend picker, places picker, profile pictures, and login controls. Developers build apps faster by dropping these elements into their apps. The new kit will also allow developers to measure clicks and installs for "mobile app install ads" -- i.e., mobile ads that implore users to install new apps. The social network opened up these ads, which allow developers to places these sorts of ads in users' mobile News Feeds, to all third-party developers yesterday.
Facebook says the pre-built interface functions means more installs and more people using the app regularly. The social network is doing more of the development legwork, so developers can spend more time building and improving other parts of their apps. In the end, this should mean better app experiences for users.
