Abstract: A method and apparatus for displaying a target application across one or more devices is disclosed. The method includes determining a functional module within the target application running on a first device, where the module comprises one or more pages. A transfer parameter and a configuration parameter of the functional module are parsed. The transfer parameter identifies the target device—either the first device or a second device—for display of the module, while the configuration parameter defines display-related information. Based on the transfer parameter, the functional module is selectively transferred to and laid out on the determined target device. The system supports flexible multi-device display scenarios, including fixed, sequential, exclusive, or terminal transfer modes, enabling adaptive rendering of application modules across heterogeneous devices.
