Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment,
And referring to the drawings, the present invention is described in more detail.
The schematic flow sheet of the embodiment of the method for a kind of internal memory optimization that Fig. 1 provides for the present invention.As schemed
Show, in the embodiment of the method for a kind of internal memory optimization of present invention offer, including:
S10, arranges at least two copy varied in size for resource file；In the process that foreground program runs
In, for transferring and perform the state of the service processes of resource file in detection operation:
S11, has detected whether that service processes suspends；If there being service processes to suspend, perform step S12.
S12, terminates this service processes.
In the prior art scheme, the service processes of time-out can be suspended without being terminated, so on the one hand
Conveniently again call, on the other hand can reduce judgement step during programming, reduce program capacity.
But, for mobile terminal, for particularly configuring relatively low mobile terminal, service processes is EMS memory occupation
Major part, the service processes of hang-up can take substantial amounts of memory source, so that perform system every time
Memory source amount available after cleaning is still little, will soon again trigger cleaning, cause program card to pause.
S13, has detected whether service processes calling resource file；If there being service processes calling resource file,
Perform step S14.
S14, obtains the EMS memory occupation state that system is current, transfers this resource according to described EMS memory occupation state
The copy that file is appropriately sized.

Source file copy is finished, and performs step S16.
S16, discharges this resource file copy.
Similar with service processes, in the prior art, resource file copy also will not be at once after being finished
Cleaned, but hang up with service processes belonging to it, this result in some service processes actually used in
Resource file amount is little, but the memory headroom that useless resource file takies is the biggest, and these are useless
Resource file system perform cleaning time can be judged as cannot being cleared up by service processes, with
Reason also can cause program frequently to clear up internal memory card.
Service processes running status is monitored by the present embodiment, by terminate in time time-out process, choose suitable
When the resource file copy of size discharges the modes such as resource file copy with timely, before ensureing Consumer's Experience
Put the EMS memory occupation amount reducing foreground program as far as possible, thus reduce system and perform the frequency of internal memory cleaning,

With resource file, it is determined that described service processes suspends；If described service processes is currently in use resource file, hold
Row step S21.
S21, detects whether this resource file is in system background；If this resource file is in system background,
Judge that described service processes suspends.
In the present embodiment, the criterion that service processes suspends this state is extended.Except logical
The upper service processes of Chang Yiyi does not use resource file then to judge outside its time-out, if this service processes is currently in use
Resource file be in system background, also judge that this service processes suspends；So used when this service processes
Resource file (such as some specially good effects or operation interface etc.) when being temporarily hidden in backstage, then by this money of support
The service processes of source file is also judged to suspend；And the service processes suspended is terminated, discharges what it took
Memory source, to reduce the internal memory usage amount of program.

S30, obtains the free memory value of system spare.
S31, by the copy of described resource file according to data volume from big to small order sequence.
S32, judges whether the copy of described resource file is less than the free memory value of described system spare successively；
If so, first described copy less than the free memory value of described system spare is transferred.
Method in the present embodiment can accommodate by choosing current system remaining free memory value
Big resource file copy, uses on the premise of not triggering Installed System Memory cleaning that data volume is big as far as possible, product
The Resource Replica that matter is the highest, thus bring preferably Consumer's Experience.
The schematic flow sheet of the alternative embodiment of the method for a kind of internal memory optimization that Fig. 4 provides for the present invention.As

Whether duplicate of the document is finished；If it is determined that this resource file copy is finished, its status indicator is arranged
It is discarded.
S41, after usable levels Installed System Memory being detected is less than the cleaning threshold preset, by status indicator be
Discarded described resource file copy removes from Installed System Memory.
Present embodiments provide a kind of method solving the resource file halfway problem of cleaning.Solve
Releasing, resource file copy also will not be the most cleaned after being finished, but with service belonging to it into
Journey is hung up, this result in some service processes actually used in resource file amount little, but useless money
The memory headroom that source file takies is the biggest, and the meeting when system performs cleaning of these useless resource files
It is judged as cannot being cleared up by service processes, program the most also can be caused frequently to clear up internal memory also
Card.
Therefore, the present embodiment arranges status indicator to the copy of the useless resource file that these are finished is useless
Abandon, these resource file copy with discarded mark be can be removed, without wait when performing cleaning

EMS memory occupation desired value.
S51, uses the total amount of Installed System Memory to deduct the sum of described service processes EMS memory occupation desired value, then subtracts
Remove the adjusted value preset, obtain described cleaning threshold.
The adjusted value here preset at for balanced service process in actual moving process contingent, take
Actual memory amount is more than the situation of its EMS memory occupation desired value.In some cases, if after above-mentioned calculating
The cleaning threshold obtained is the value of no more than 0, then explanation service processes is more；In an alternate embodiment of the invention,
If the value that cleaning threshold is no more than 0 obtained after calculating, described cleaning threshold is set in system
The total amount deposited is multiplied by default cleaning coefficient.Here the preferable span clearing up coefficient be [0.7,1).
S52, if that described service processes EMS memory occupation desired value detected and change, after changing
Described EMS memory occupation desired value and recalculate described cleaning threshold.
Step S52 updates cleaning threshold for the change calculations according to service processes running status.Deposit into when interior
When journey is more, a less cleaning threshold can be calculated；When internal memory process is less, can be calculated
One bigger cleaning threshold.The establishing method of this dynamic adjustment is relative to cleaning threshold is set to one
Definite value, can obtain a less cleaning threshold, thus avoid because of cleaning threshold when internal memory process is more
Excessive cause frequently internal memory cleaning；In like manner when internal memory process is less, a bigger cleaning can be obtained
Threshold value, the most internally counter foil row cleaning, removes useless service processes or resource file in time,
To ensure that new service processes has the Installed System Memory of abundance to use when being activated.
