Abstract: A cross-device content projection method includes a first electronic device starting to play first content. The first electronic device obtains, from a near-field communication (NFC) tag, N second electronic devices bound to the NFC tag, where N is an integer greater than 1. The first electronic device projects, according to a preset projection policy, the first content onto at least two of the N second electronic devices for continuous playing.
