Background Application Management via Whitelist Priority

The patent applies local quality by differentiating between ordinary background applications and frequently used applications. A whitelist mechanism is introduced to identify frequently used applications, allowing the system to treat them differently from other background applications. When memory pressure occurs, only non-whitelisted applications are exited, while whitelisted applications are preserved regardless of their memory consumption. This localized differentiation resolves the contradiction by protecting user experience for important applications while still managing memory resources effectively.

The patent implements feedback through the whitelist mechanism that captures user preferences about frequently used applications. The system continuously monitors which applications users access and maintains this information in a whitelist. When memory management decisions need to be made, the system refers back to this feedback information to determine which applications to preserve. This feedback loop ensures that memory management aligns with actual user behavior and preferences, resolving the contradiction between memory release and user experience.

The patent applies local quality by creating distinct treatment categories for different applications based on their importance to the user. The whitelist identifies locally important applications that deserve special protection, while other background applications can be managed more aggressively. This allows the system to maintain multiple background applications for user convenience while selectively managing memory resources to preserve processing speed, resolving the contradiction through differentiated quality treatment.

The patent changes the parameter of application priority by introducing a whitelist flag that modifies how applications are treated during memory management. Applications in the whitelist have their effective priority changed from normal to high, ensuring they are preserved during memory pressure events. This parameter change allows the system to simultaneously support multiple background applications and maintain processing speed by dynamically adjusting which applications consume memory resources.
