# dmsfwk

## Introduction

The Distributed Ability Manager Service Framework (dmsfwk) component is used for cross-device component management. It allows the local device to access and control remote components, and enables application collaboration in distributed scenarios. Major functions are as follows:

-   Remote ability startup: starts an ability on a remote device. Data can be returned when the Page ability ends.
-   Ability continuation: continues an ability on a remote device.
-   Remote ability binding: binds an ability on a remote device.
-   Remote call: obtains the caller interface of a remote ability to call the ability across devices.
