Push-button synthesis of watch companions for Android apps
Cong Li, Yanyan Jiang, Chang Xu · Proceedings of the 44th International Conference on Software Engineering · 2022
Most Android apps lack their counterparts on convenient smart-watch devices, possibly due to non-trivial engineering efforts required in the new app design and code development. Inspired by the observation that widgets on a smartphone can be mirrored to a smartwatch, this paper presents the Jigsaw framework to greatly alleviate such engineering efforts. Particularly, Jigsaw enables a pushbutton development of smartphone's companion watch apps by leveraging the programming by example paradigm, version space algebra, and constraint solving. Our experiments on 16 popular open-source apps validated the effectiveness of our synthesis algorithm, as well as their practical usefulness in synthesizing usable watch companions.
