Using a projected out of memory score to selectively terminate a process without transitioning to a background mode

Abstract

Methods and apparatus such as a processor platform to manage a process under a memory constraint are disclosed herein. An example method includes detecting that a process is to transition from a foreground mode of operation to a background mode of operation. Without transitioning the process to the background mode of operation, a projected out of memory score is calculated. The projected out of memory score is compared to a score threshold, and the process is terminated when the projected out of memory score is greater than the score threshold. When the projected out of memory score is less than or equal to the score threshold, the process is allowed to transition to the background mode of operation. A priority adjustor may determine a projected adjustment value, for example by determining a default adjustment value, or by performing a lookup of an adjustment value currently associated with a second process operating in the background mode. The background mode of operation may be at least one of a visible application, a secondary server, a hidden application, a content provider, or an empty application. Freeing up memory in advance of a subsequent low memory check ensures that low memory conditions are avoided more promptly.
