Figure 3 shows that mobile terminal first embodiment of the present invention, for simplicity, illustrate only the unit module that in mobile terminal, function data cached to Automatic clearance is relevant in Fig. 3, eliminate other general module and parts.Described mobile terminal comprises judge module and cleaning module, wherein:
Judge module: for judging whether terminal stops data transmitting, when terminal stops data transmission, judges whether the data cached application being greater than first threshold, and judged result is sent to cleaning module.
When detecting that terminal closes data service, or when not having data to transmit in Preset Time (as there is no packet or network interaction), judge module then judges that terminal stopped data transmission, now clears up data cached, can not affect the normal use of user to mobile terminal.Then, whether there is the data cached application being greater than first threshold (as 500M) in judge module sense terminals, and judged result is sent to cleaning module.
Described first threshold can have multiple, is namely provided with different threshold values for different application, according to the characteristic of application and the needs of user, for some application arrange higher threshold value, for other application arrange lower threshold value.
Cleaning module: for when judged result be have data cached be greater than the application of first threshold time, delete the data cached of described application.
If judged result is do not have the data cached application being greater than first threshold in terminal, then do not perform cleaning operation; If judged result is have the data cached application being greater than first threshold in terminal, cleaning module then delete these application in data cached, realize, to Automatic clearance data cached in terminal, vacateing the storage space of terminal in time.Further, cache garbage collection mechanism can also be set, after clearing up by mistake, the data by mistake can deleted according to the reduction of cache garbage collection mechanism.
In a preferred embodiment, judge module, after terminal stops data transmission, also judges whether residual memory space is less than Second Threshold (as 300M) simultaneously, and judged result is sent to cleaning module.
When judged result be residual memory space be less than Second Threshold and have in terminal data cached be greater than the application of first threshold time, cleaning module then delete these application data cached.Further, when delete these application data cached after, judge module continues to judge whether residual memory space is less than Second Threshold, and judged result is sent to cleaning module.When judged result be residual memory space be still less than Second Threshold time, cleaning module then according to preset ordering rule each application is sorted, according to sequence delete the data cached of each application successively, until residual memory space is more than or equal to Second Threshold.Such as, according to data cached size, each application is sorted, delete the data cached of each application successively according to order from big to small, until residual memory space is more than or equal to Second Threshold.In other words, cleaning module is deleted at every turn currently has the data cached of the application of largest buffered data, often delete once, judge module then judges whether a current residual storage space is less than Second Threshold, when residual memory space is still less than Second Threshold, cleaning module continuation deletion is current has the data cached of the application of largest buffered data, final until judge module judges that current residual storage space is more than or equal to Second Threshold, cleaning end.Described ordering rule can also be: the importance according to application program sorts, and the frequency of utilization according to application sorts, and the data cached size exceeding first threshold according to each application sorts, etc.
When judged result be residual memory space be less than Second Threshold but do not have in terminal data cached be greater than the application of first threshold time, cleaning module then sorts to each application according to data cached size, the data cached of each application is deleted successively according to order from big to small, judge module continues to judge whether residual memory space is less than Second Threshold during this period, when residual memory space is still less than Second Threshold, it is data cached that cleaning module then continues deletion, until residual memory space is more than or equal to Second Threshold.Or, cleaning module also can random erasure apply arbitrarily data cached, until residual memory space is more than or equal to Second Threshold.Or cleaning module also can delete the data cached of all application.
When judged result be residual memory space be more than or equal to Second Threshold but have data cached be greater than the application of first threshold time, cleaning module then delete these application data cached or do not perform cleaning operation.
When judged result be residual memory space be more than or equal to Second Threshold and do not have data cached be greater than the application of first threshold time, cleaning module then do not perform cleaning operation.
Or, only have when judge module judges that residual memory space is less than Second Threshold, just continue to judge whether the data cached application whether being greater than first threshold; Otherwise no longer respond, terminate this clean-up process.When have data cached be greater than the application of first threshold time, cleaning module then delete these application data cached; Otherwise, according to data cached size, each application is sorted, deletes the data cached of each application successively according to order from big to small, until residual memory space is more than or equal to Second Threshold, just terminate this cleaning operation.
Thus, the mobile terminal of the present embodiment, when stopping data transmission, then judge whether satisfied cleaning condition, when satisfied cleaning condition, then delete the data cached of related application, achieve Automatic clearance data cached in terminal, both can not affect user and use terminal, prevent too much buffer memory rubbish from taking storage space, vacate the storage space of terminal in time, and avoid a large amount of buffer memory rubbish to affect the travelling speed of terminal.
