Abstract: This disclosure provides synchronization methods and apparatuses for cross-device navigation tasks. One method includes: a first terminal obtains navigation data from a first navigation application through a first navigation transfer module in response to a preset cross-device transmission condition is satisfied. The first terminal generates navigation synchronization information of the navigation data through the first navigation transfer module. A second terminal receives the navigation synchronization information sent by the first terminal, and transmits the navigation synchronization information to a second navigation application through a second navigation transfer module, and updates a navigation task of a second navigation application based on the navigation synchronization information.
