Abstract: 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.

Abstract: A method for managing a trigger on a terminal device, and a terminal device are provided. In response to an operation (S301) of setting a trigger by an application program (181), a trigger manager (235) determines a triggering policy of the trigger based on a use habit of a user, characteristic information of the trigger, and characteristic information of the application program. The triggering policy is accelerating triggering, normal triggering, or delaying triggering. Different triggering policies are executed for triggers having different characteristics, to dynamically change timings for the triggers to trigger scheduled tasks. In this way, a malicious trigger configured to keep an application alive or trigger a task that does not match a true will of the user is prevented to reduce resource consumption, and a trigger beneficial to a system or the user can be triggered earlier to improve user experience.

Abstract: An application start method includes obtaining a target application list when a size of free memory is greater than a preset threshold. The target application list is used to store one or more application identifiers of one or more applications whose memory is released. The application start method further includes starting, in the background, a process of an application identified in the target application list.

Abstract: A route selection method and apparatus includes a first mesh node for selecting a route obtains energy consumption information of at least two second mesh nodes, where the second mesh node provides a route for the first mesh node; and the first mesh node selects a route according to the energy consumption information of the at least two second mesh nodes.

Abstract: 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.
