To improve the mobile performance of its social network, Facebook is enhancing Java bytecode on the Android platform with its Redex project, providing a pipeline for optimizing Android DEX (Dalvik Executable) files.
In a blog post, Facebook engineers Marty Greenia, Bert Maher, and Shane Ney emphasized a responsibility to "keep things fast," particularly in developing areas where devices stay in the market longer. "Android is one of our biggest platforms, and it's also the mobile platform with the greatest diversity of devices. Any performance or efficiency improvements on these devices could improve the experience of millions of people around the world," according to the post.
