This application provides information processing methods, terminal devices, and distributed networks. In an implementation, after determining target information including at least one piece of text information and at least one piece of non-text information, a terminal device may determine, based on a predetermined playing speed and a predetermined time, at least one first location associated with at least one piece of non-text information. Text-to-speech is sequentially performed on the at least one piece of text information, to obtain and sequentially play speech information respectively corresponding to the at least one piece of text information. In response to speech information corresponding to first text information being played, target non-text information is sent to a second terminal device, so that the second terminal device displays the target non-text information.

Information processing method, terminal device, and distributed network

An application permission management method, device, and medium. The method includes obtaining, by an electronic device, operation information of starting, by a user, a first application installed in the electronic device, sending a permission query request for the first application to a server, where the permission query request includes an identifier of the first application, receiving a permission authorization record of the first application sent by the server, and configuring permission of the first application on the electronic device based on the permission authorization record.

Application permission management method and apparatus, and electronic device

A display method, an apparatus, and a storage medium are provided. The method includes: rendering, by a first container, a to-be-displayed page to generate to-be-displayed image data, and encrypting the image data; and writing, by the first container, encrypted image data into a buffer corresponding to the first container, and sending instruction information to a second container of a terminal, where the instruction information is used to instruct the second container to securely display the encrypted image data. Because the containers are isolated from each other, the malware in the first container cannot access the image data displayed in the second container, and the second container securely displays the encrypted image data. In this way, security of displaying the image data can be improved while ensuring that an image display function is not restricted.

Display method, apparatus, and storage medium

The disclosure provides a method for managing multiple operating systems in a terminal. The terminal includes multiple operating systems and a management system. The management system is configured to manage the multiple operating systems. The management system includes a cross-system application database. The method includes: when a first operating system in the multiple operating systems runs in a foreground, and a second operating system in the multiple operating systems runs in a background, if the second operating system receives a first message of a first application in the second operating system, sending, by the second operating system, a notification message to the management system; storing, by the management system, the notification message into the cross-system application database; and listening, by the first operating system, on the cross-system application database, and outputting a prompt of the first message when listening and obtaining the notification message.

Method for managing multiple operating systems in a terminal

The disclosure provide a method for prompting a message in a terminal and a terminal. The terminal includes multiple operating systems and a management system. The management system is configured to manage the multiple operating systems. The management system includes a cross-system application database. The method includes: when a first operating system in the multiple operating systems runs in a foreground, and a second operating system in the multiple operating systems runs in a background, if the second operating system receives a first message of a first application in the second operating system, sending, by the second operating system, a notification message to the management system; storing, by the management system, the notification message into the cross-system application database; and listening, by the first operating system, on the cross-system application database, and outputting a prompt of the first message when listening and obtaining the notification message.

An operating system hot-switching method, applied to a mobile terminal running multiple operating systems, where the multiple operating systems include one foreground operating system and at least one background operating system, a current foreground operating system is a first operating system. The method includes obtaining an operating system switching instruction, where the operating system switching instruction includes an identifier of the second operating system and a switching identifier, releasing, according to the switching identifier, a hardware resource occupied by the first operating system, and switching the foreground operating system from the first operating system to the second operating system. Hence, the operating system hot-switching method ensures, to some extent, mutually exclusive access to and coordinated use of a hardware resource by multiple operating systems, thereby ensuring use reliability of the hardware resource after switching of an operating system.
