摘要： A message processing method is provided, and includes: first sending, by a terminal, first data to an external display device after the terminal establishes a connection to the external display device, to instruct the external device to display a first interface in full screen mode; sending, by the terminal, a first instruction to the external display device after the terminal receives a new message of a first application, to instruct the external display device to display first notification information; and when the terminal receives a first input operation performed by a user on the first notification information, displaying, by the terminal, a third interface, and sending second data to the external display device, to instruct the external display device to divide a display area of the external display device into a first display area and a second display area; and displaying, in the first display area, a fourth interface obtained after the first interface is scaled down proportionally, and displaying, in the second display area, a fifth interface that has a same interface element as the third interface. In this way, the external display device can simultaneously display a plurality of independent display interfaces in split-screen mode, so that the user can simultaneously operate the plurality of display interfaces.

摘要： An audio playing method and an electronic device relate to the field of electronic device technologies. An audio playing method is provided to resolve a prior-art problem of privacy leakage caused because audios from different multimedia applications are all played by using a speaker of an external audio device. The method includes: after an electronic device establishes a connection to an external audio device, obtaining, by the electronic device, a to-be-played audio; when the to-be-played audio is associated with the electronic device, playing, by the electronic device, the to-be-played audio; and when the to-be-played audio is associated with the external audio device, sending, by the electronic device, the to-be-played audio to the external audio device over the established connection, so that the external audio device plays the to-be-played audio. This application is applicable to a process in which an audio is played after the electronic device is connected to an external device.
