Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistented with the present invention.On the contrary, they be only with it is such as appended
The example of device and method being described in detail in claims, some aspects of the invention are consistent.
The embodiment of the invention provides a kind of downloading management method, this method can be used in terminal device, as shown in Figure 1,
The method comprising the steps of S101-S105:
In step s101, when application program carries out resource downloading, control application program is the interim memory of resource allocation
Value；The interim memory value is less than maximum committed memory value of the application program in terminal device；
In step s 102, maximum committed memory value of the application program in terminal device is obtained；
In step s 103, the ratio between interim memory value and maximum committed memory value is calculated；
In step S104, ratio is compared with default ratio；
In step s105, when ratio is greater than or equal to default ratio, start garbage collecting function GC (Garbage
Collection), to be recycled to the corresponding waste resources of application program.
In the technical scheme, when application program carries out resource downloading, calculating application program is the interim of resource allocation
The ratio of the maximum committed memory value of memory value and application program in terminal device, and the ratio and default ratio are carried out
Compare, when the ratio is greater than or equal to default ratio, start garbage collecting function, to the corresponding waste resources of application program into
Row recycling avoids memory load excessive and influences speed of download, cause in this manner it is ensured that downloading process smooth can carry out
There is Caton in downloading.
For example, it is 60% that default ratio, which is arranged, then the ratio between interim memory value and maximum committed memory value is greater than
Or when being equal to 60%, downloading is it is possible that therefore Caton can star garbage collecting function, recycling rubbish, thus under guaranteeing
Load process smooth can carry out, and avoid memory load excessive and influence speed of download, downloading is caused Caton occur.
As shown in Fig. 2, in one embodiment, before above-mentioned steps S104, the above method further includes step S201-
S204:
In step s 201, the unused memory value in interim memory value is obtained；
In step S202, it is calculated according to unused memory value and interim memory value and has used memory value；
In step S203, the usage rate used between memory value and interim memory value is calculated；
In step S204, default ratio is determined according to usage rate.
In this embodiment it is possible to default ratio be determined according to the usage rate of interim memory value, to guarantee
Start GC when suitable, because if pre-cooling GC, because GC itself is also cost source, the consumption of system can be increased.
If delaying starting GC, cause downloading not smooth.Therefore, default ratio is determined according to the usage rate of interim memory value
Value, it is ensured that downloading process smooth can carry out.
As shown in figure 3, in one embodiment, above-mentioned steps S204 includes step S301-S302:
In step S301, the peak value of usage rate is obtained；
In step s 302, the peak value of usage rate is determined as default ratio.
In this embodiment, the usage rate of interim memory value is dynamic change, but it has peak value to be
Interim memory value accounts for the ratio of the maximum committed memory value of each application, when getting this value by calculating and test, under
Carrying speed can reach most fast, therefore, can be using this peak value as default ratio.
For example, temporarily distribute in save as 4M, rubbish can download generation Caton, that is, 2M after occupying 50%.It is so real
When monitor rubbish quantity, start GC when reaching 2M.
Alternatively, the size of a high definition picture is 500K, text be can be ignored.So 4 high definition pictures with regard to it is poor not
More 2M.So downloading and just starting GC after loading 4 high definition pictures.
As shown in figure 4, in one embodiment, above-mentioned steps S101 includes step S401-S402:
In step S401, controls corresponding application program and obtain currently available memory value；
It is the interim memory value of resource allocation according to currently available memory value in step S402.
In this embodiment, application program can carry out the distribution of interim memory according to the currently running memory situation of system,
To guarantee the normal operation of system.
As shown in figure 5, in one embodiment, the above method further includes step S501-S502:
In step S501, the default ratio setting command of input is received；
In step S502, default ratio is arranged according to default ratio setting command.
In this embodiment, default ratio can also rule of thumb oneself be arranged in user, to guarantee when suitable
Starting GC, because GC itself is also cost source, can increase the consumption of system because if pre-cooling GC.It is opened if delayed
Dynamic GC, then cause downloading not smooth.Therefore, the suitably default ratio of setting, it is ensured that downloading process smooth can carry out.
Wherein, each application program maximum committed memory value is one dynamic value-calculation formula are as follows:
IntmaxMemory (the current maximum committed memory value of terminal device)=((int) Runtime.getRuntime
().maxMemory())/1024/1024；
The memory value that interim memory value i.e. current application program are got, calculation formula are as follows:
Long totalGetMemory=((int) Runtime.getRuntime () .totalMemory ())/1024/
1024；
Interim memory value accounts for the percentage of each application program maximum committed memory value are as follows:
Int maxPercent=totalGetMemory/maxMemory
Unused memory value in interim memory value are as follows:
Long freeMemory=((int) Runtime.getRuntime () .freeMemory ())/1024/1024；
The usage rate of interim memory value are as follows:
Int usingMemoryPercent=(totalGetMemory-freeMemory)/totalGetMemory
Following is embodiment of the present disclosure, can be used for executing embodiments of the present disclosure.
