Releasing memory can preferentially be closed.
When current shielded application program is current foreground program, specifically, such as: probe service routine is rear
Platform counts the data of foreground IPTV application program, and priority is judged as low.But probe server program and IPTV application program
Has relevance.When memory is lower than preset threshold value, due to IPTV application priorities highest, even if probe program
Priority is low, is also unlikely to be closed.
By the above-mentioned means, can guarantee core application and its associated program, foreground application and its association journey
Sequence is not released.
In conclusion in the present embodiment, due to establishing the incidence relation between each application program, and associated with
Form be stored in the system of intelligent terminal.After intelligent terminal starting, intelligent terminal residue is detected
Memory lower than threshold value need to close application program carry out releasing memory when, it is minimum that inquiry application priority list finds out priority
Application name, read associated with, and judge whether the minimum application program of priority shielded answers with current
Use program.If can be closed without incidence relation.Otherwise the higher leveled process of priority is required to look up, is recycled above-mentioned
Process.Due to designating the incidence relation of each application program in associated with, then needing to close application program in low memory
When, it can guarantee that pent application program does not interfere with the business for the application program being associated.
