Google is developing a feature called "App Cast" within the Android ecosystem, as indicated by references found in the 25.24.31 beta release of Google Play Services. This feature may allow users to gather information from remote Android devices and access their installed applications, potentially enabling app streaming between devices. Code snippets suggest functionalities for multi-device synchronization, including device selection and progress indicators. There are also hints of new notification sync capabilities related to App Cast. Further updates from future Play Services builds are expected to clarify the details and implications of this feature.
