DATA SYNCHRONIZATION METHOD, ELECTRONIC DEVICE, AND COMPUTER READABLE STORAGE MEDIUM

Embodiments of this application disclose a data synchronization method, an electronic device, and a computer-readable storage medium. The method includes: obtaining first to-be-synchronized data of a first application in a first electronic device; determining a first channel identifier, where the first channel identifier is an identifier allocated by a second electronic device to a second application in the second electronic device, and each first channel identifier corresponds to one second electronic device; determining a connection channel corresponding to the first channel identifier, where the connection channel is a connection channel that has been established between the first electronic device and the second electronic device, and each first channel identifier corresponds to one connection channel; and transmitting the first to-be-synchronized data to the second electronic device through the connection channel corresponding to the first channel identifier, to indicate the second electronic device to synchronize the first to-be-synchronized data to the second application. In embodiments of this application, cross-device application data synchronization in a near field environment is implemented without depending on a cloud server and an account login mechanism.
