2021 dual-screen year in review

Hakon Strande

Hello Android developers!

2021 was a big year for dual-screen devices with the release of Microsoft Surface Duo 2. It has also been a busy year for developers with Jetpack Window Manager – Google’s common API for foldable device info – graduating from alpha to beta and then release candidate, the SlidingPaneLayout control was enhanced for foldables, and we also expanded our platform support to Jetpack Compose and Flutter.

With the year quickly coming to a close, this week we’re going to revisit some of the most popular content from the Surface Duo developer blog.
