Facebook SDK for Android integrates with Facebook with the aim to build social apps and engage audiences. This SDK requires Android API level 9. It offers bolts, audience network, and Facebook packages. Android SDK includes login, app events, share, ads, custom stories, graph API, app links, send request, and app center. The particular functionality of each feature aims to enhance development experience. For example, app events measure the effectiveness of an application according to users' behavior; ads can increase user engagement via news feed; custom stories show how to use the Object API; and app links allows to handle incoming links to redirect users to an application using shared posts, stories, and requests.
