Today, we're releasing a new version of Facebook for Android that's been rebuilt in native code to improve speed and performance. To support the unique complexity of Facebook stories across devices, we're moving from a hybrid native/webview to pure native code, allowing us to optimize the Facebook experience for faster loading, new user interfaces, disk cache, and so on.
We rebuilt several of Facebook for Android's core features in native code, including news feed and Timeline, to create a faster experience whether you're opening the app, looking at photos, or interacting with friends. Now, you can comment and like a story more quickly, and photo loading is optimized to be much faster. We also built a new, automatically updated story banner to bubble up the newest stories, no matter where you are in news feed.
We found that we had to develop new solutions and abstractions in order to address several performance challenges along the way.
