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

A memory management method includes determining a memory page that needs to be swapped out of a memory, for each memory page that needs to be swapped out, generating, based on the memory page, a work task reclaiming the memory page, and allocating each work task to a dedicated worker thread for execution.

Memory management method and apparatus

This disclosure disclose a terminal control method and a terminal. The method may include: when detecting that the front-facing camera is in a low power consumption mode, sending, by the second processor, a first message to the first processor, where the first message indicates that the front-facing camera is in the low power consumption mode; after receiving the first message, controlling, by the first processor, the front-facing camera to collect a low-power-consumption-mode image in the low power consumption mode; receiving, by the first processor, the low-power-consumption-mode image and identifying whether there are a predetermined quantity of consecutive low-power-consumption-mode images that include preset characteristic information, where the preset characteristic information is characteristic information indicating that a user currently needs to use the terminal; and adjusting, by the first processor, brightness of a screen of the terminal according to an identification result.

Embodiments of the present disclosure disclose example broadcast message management methods and a broadcast message management apparatus. One example method includes receiving a broadcast message sent by a target application program, determining a user experience assurance priority of the target application program, and determining a target broadcast queue corresponding to the target application program. The broadcast message is saved in the target broadcast queue, and, when a broadcast message scheduling request is received, the broadcast message stored in the target broadcast queue is scheduled according to a target broadcast message scheduling priority corresponding to the target broadcast queue.

Broadcast message management method and apparatus

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.

A memory management method and apparatus to resolve a problem that a memory reclaiming rate is relatively low, severely affecting memory allocation performance in a scenario in which system memory is insufficient. The method includes determining a memory page that needs to be swapped out of a memory, for each memory page that needs to be swapped out, generating, based on the memory page, a work task reclaiming the memory page, and allocating each work task to a dedicated worker thread for execution. In this way, a plurality of central processing units (CPUs) process memory reclaiming in parallel, thereby accelerating memory reclaiming, and improving user experience.

Embodiments of the present disclosure disclose a broadcast message management method, including: receiving a broadcast message sent by a target application program; determining a user experience assurance priority of the target application program, and determining a target broadcast queue corresponding to the target application program; saving the broadcast message in the target broadcast queue; and when a broadcast message scheduling request is received, scheduling, according to a target broadcast message scheduling priority corresponding to the target broadcast queue, the broadcast message stored in the target broadcast queue. The embodiments of the present disclosure further disclose a broadcast message management apparatus.
