Abstract: A method includes setting an execution condition of a custom function of an electronic device; determining whether a touch operation performed by an external device is detected; if a touch operation performed by the external device is detected, obtaining status information of the electronic device in response to the touch operation; determining whether an authorization status of the electronic device is a first state; if the authorization status of the electronic device is the first state, waiting to receive a connection request sent by the external device, where the connection request carries authentication information; determining whether the authentication information is correct, and whether a quantity of valid touches and a touch time meet the execution condition; and if the authentication information is correct, and the quantity of valid touches and the touch time meet the execution condition, performing the custom function.

Abstract: This application provides a stereo networking method, an electronic device, an audio device, and a storage medium. In a system including the electronic device and the audio device, the audio device generates a Bluetooth broadcast message and sends to the electronic device, where the Bluetooth broadcast message indicates whether the audio device has established stereo and whether the audio device is allowed to establish stereo. When determining, based on the Bluetooth broadcast message, that a second audio device available for establishing stereo exists, the electronic device pops up a stereo establishment pop-up box, to ask a user whether to allow the electronic device to establish stereo or re-establish stereo. Based on short-range communication, the electronic device may directly and automatically discover an audio device available for establishing stereo, and establish stereo with the audio device based on a user requirement.
