<Embodiment>
<Method>
In the present embodiment, a kind of picture loading method is provided.The picture can pass through the electricity arbitrarily with display device
It is applied to corresponding application interface after sub- equipment load, for example, it may be the icon of application interface, button graphic etc..
The picture loading method, as shown in Fig. 2, including step S2100-S2300.
Step S2100 obtains the bitmap file of Target Photo to be loaded, determines whether bitmap file meets preset add
Carrier strip part.
In the present embodiment, the picture that can be used when Target Photo is corresponding application rollouts application interface, such as
Can be program icon, notification bar icon etc..
Bitmap file (also known as raster pattern, digital image or bitmap), is indicated using pel array
The color information of image, each pixel is indicated by RGB combination or gray value.
The bitmap file for obtaining Target Photo can middle reading be locally stored, or the electronics of implementation the present embodiment is set
Standby other application module, obtains after being encoded according to the data of the Target Photo received；It usually can be by reading mesh
It marks on a map the data file of piece, file type is obtained by preceding 2 bytes in the byte stream of the data file, judges the Target Photo
Data file whether be corresponding bitmap file.
In this application, it is not in abnormal or failure condition that loading environment, which is picture load, can be according to specific
Picture loading scenario or picture load demand setting.By the way that loading environment is arranged, for judging that the bitmap file of Target Photo is
The no normal load for supporting Target Photo, to trigger corresponding position when the bitmap file of Target Photo does not meet loading environment
Reason avoids the occurrence of picture load failure.
In an application scenarios, inventor has found, if the bitmap file of file destination, which does not have to meet, answers scene
Target code format, it may appear that Target Photo load failure.For example, for some application program, the mobile phone of certain types is installed
After can will appear the notification bar icon in application interface after the mobile phone installation of certain types without Faxian with normal presentation application interface
Show or blackening as picture load failure the phenomenon that, applicant by largely testing and interpretation of result, be the discovery that because
There is the mobile phone of picture load when Loading Image display application interface, has used and do not met the bitmap that the application program is supported
The coded format of file, for example, it is Bitmap.Config.ARGB_8888 formats that application program, which requires the bitmap file used,
And the bitmap file for the Bitmap.Config.ARGB_565 formats that the mobile phone acquiescence for picture load failure occur uses, cause to answer
It is mounted on such mobile phone and is failed with program, and the bitmap file of Bitmap.Config.ARGB_565 formats can due to it
To use capacity more smaller than Bitmap.Config.ARGB_8888 format that 8 bits is used to express each pixel, using more
Generally.
For above-mentioned application scenarios, loading environment, which can be set to bitmap file, has preset target code lattice
Formula.For example, target code format is Bitmap.Config.ARGB_8888.
Accordingly, the step of whether bitmap file meets preset loading environment determined, as shown in figure 3, including：Step
S2110-S2130。
Step S2110, parsing bitmap file obtain corresponding byte stream, determine and whether there is key parameter in byte stream.
In the present embodiment, key parameter includes at least one of transparency parameter or color mode parameter.It is transparent
Spending parameter is and the relevant parameter of Target Photo.Color mode parameter is and the color mode of Target Photo (such as RGB patterns)
Relevant parameter.
Include one of transparency parameter or color parameter in the byte stream of bitmap file, corresponds to after Loading Image
The visual effect of displaying is generally more abundant, and user experience is more preferable, and accordingly, the coded format of the bitmap file is to meet application
The target code format of scene demand.
For example, bitmap file generally includes bitmap file head, message bit pattern head and bitmap data.When parsing bitmap file
Byte stream obtains message bit pattern head, when the digit for reading message bit pattern head is 8 (256 color), passes through before interception bitmap data 8
(since the digit for being bitmap is 8, preceding 8 units can indicate a pixel, and this 8 are come according to bluish-green red Alpha for position
Sequence), two judgements last in this 8 are read, then prove to be not provided with transparency parameter if it is 0 value, i.e., in byte stream
There is no this key parameter of transparency parameter, then corresponding coded format be Bitmap.Config.ARGB_565 and if it is
Non-zero value, then there are this key parameters of transparency parameter, corresponding coded format i.e. in byte stream is
Bitmap.Config.ARGB_8888。
Step S2120, when in byte stream there are when key parameter, determine bitmap file have target code format, meet
Loading environment.
Step S2130 determines that bitmap file does not have target code format when key parameter is not present in byte stream,
Loading environment is not met.
And for certain electronic equipments for implementing the present embodiment, it is limited to equipment performance, can not support side as described in Figure 3
By parsing the byte stream of bitmap file determines the step of whether corresponding Target Photo meets loading environment in method.
Therefore, in one example, loading environment can be set to bitmap file and have with corresponding sample bitmap file
There is consistency.
Accordingly, the step of whether bitmap file meets preset loading environment determined, as shown in figure 4, including：Step
S2101-S2104。
Step S2101 is based on preset target code format, generates the sample bitmap file of Target Photo.
In this example, target code format is arranged according to corresponding application scenarios demand, is arranged to corresponding
The coded format that the bitmap file of more abundant visual effect is presented after picture load, for example, target code format is set as
Bitmap.Config.ARGB_8888。
Based on target code format, the sample bitmap file with Target Photo is generated, to compare mesh in conjunction with subsequent step
Mark on a map piece (actual) sample file and sample bitmap file consistency, determine whether the bitmap file of Target Photo meets
Loading environment so that without implementing as parsing bitmap file obtains byte stream to applying the higher step of performance requirement, drop
Low application performance consumption.
Step S2102 compares all bytes of bitmap file and sample bitmap file.
Step S2103 determines bitmap file and sample when bitmap file is identical as all bytes of sample bitmap file
File is with uniformity, meets loading environment.
Step S2104 is determined when bitmap file and sample bitmap file are there are when byte is different or file size difference
Bitmap file does not have consistency with sample file, does not meet loading environment.
After step S2100 determines whether bitmap file meets preset loading environment, S2200 is entered step：
When bitmap file does not meet loading environment, coded treatment is re-started to bitmap file, obtains meeting loading environment
New bitmap file.
Loading environment is arranged according to specific application scenarios or application demand.
For example, loading environment, which is bitmap file, has preset target code format.Accordingly, when bitmap file is not met
Loading environment re-starts coded treatment to bitmap file so that bitmap file has target code format, meets load item
Part.
In another example loading environment is that bitmap file and corresponding sample bitmap file are with uniformity.Accordingly, work as bitmap
File does not meet loading environment, and coded treatment is re-started to bitmap file so that bitmap file has with sample bitmap file
Consistency meets loading environment.
Bitmap file is stored in the application memory for the destination application for needing to load Target Photo by step S2300,
It is used when loading Target Photo for destination application.
Destination application is the application program needed by loading the corresponding application interface of intended display.Application program is logical
Often with there is corresponding application memory, for storing the related data provided needed for application service.Application memory is installation or load
A part for the memory of the electronic equipment of the application program, can be distributed automatically by the operating system of electronic equipment, or
It is that application program is distributed to the operating system application of electronic equipment.
In practical applications, inventor has found, when Target Photo meets loading environment, still has certain probability to scheme
The problem of piece load failure.Inventor is had found by largely testing and analyzing work when Target Photo meets loading environment
Still there is picture load failure, is because RAM leakage (OOM, out of occurs in the electronic equipment for implementing picture load
Memory), that is, the memory of application program that Loads Image is larger, leads to picture load failure.
For such case, the picture loading method provided in the present embodiment further includes：
Obtain the memory usage of application memory；
When memory usage is more than preset occupancy threshold value, preserved after bitmap file is carried out compression processing.
The memory usage of application memory is the ratio that corresponding application memory occupies all free memories.
Occupancy threshold value, which is corresponding application memory, allows the maximum rate for occupying all free memories.
When memory usage is more than preset occupancy threshold value, it is meant that the memory usage of application memory is larger,
It is likely to occur the risk of memory wrong path, is preserved after the bitmap file of file destination is carried out compression processing, can be reduced and answer
With the memory usage of memory, avoiding the occurrence of RAM leakage (OOM) leads to picture load failure.
In one example, include by the step of bitmap file progress compression processing：
Bitmap file is recompiled as the new bitmap file with prescribed coding format.
The prescribed coding format is the volume so that bitmap file capacity smaller, the corresponding less bitmap file of memory of occupancy
Code format.In one example, prescribed coding format is Bitmap.Config.ARGB_565 formats.
In practical applications, inventor has found that in certain scenes, the memory usage of application memory is excessive, even if will
It is preserved after bitmap file compression processing, can not effectively reduce the memory usage of application memory.
For such case, the picture loading method provided in this implementation can also include：
When memory usage is more than preset occupancy threshold value, bitmap file is stored in anonymous shared drive；
And/or
When memory usage is more than preset occupancy threshold value, release meets preset releasing memory item in application memory
After the process or task of part, implement the preservation bitmap file the step of.
Anonymous shared drive is usually to be provided by operating system, realized in kernel spacing in the form of driver
Shared drive, can auxiliary memory management system effectively manage the memory block not used, and pass through interprocess communication
Mechanism realizes the memory sharing between process.Bitmap file is stored in anonymous shared drive, and no longer preserves application memory
In, the memory usage of application memory further can be effectively reduced, avoiding the occurrence of RAM leakage leads to picture load failure.
Releasing memory condition is the condition that the process being currently running or task meet the corresponding committed memory of release.Releasing memory
Condition can be arranged according to specific application scenarios or application demand, for example, could be provided as the process being currently running or appoint
Business is redundancy, or is set as the running priority grade of the process being currently running or task and is less than preset running priority grade, etc.
Deng.The meeting releasing memory condition of the task or process are discharged, the memory usage of application memory can be reduced, avoided out
Existing RAM leakage leads to picture load failure.
<Example>
The picture loading method provided in the present embodiment is be provided below with reference to example shown in fig. 5.
In this example, loading environment, which is the bitmap file of Target Photo, has target code format.Target code format is
Bitmap.Config.ARGB_8888。
As shown in figure 5, picture loading method includes：Step S501-S507.
Step S501 obtains the bitmap file of Target Photo to be loaded；
Step S502, determines whether the coded format of bitmap file meets Bitmap.Config.ARGB_8888, if not
Meet ARGB888, enter step S503, otherwise, enters step S504；
It determines whether the coded format of bitmap file meets Bitmap.Config.ARGB_8888, may be used such as Fig. 3 institutes
The method shown, details are not described herein.
Step S503, recompiles bitmap file, obtains meeting the new of Bitmap.Config.ARGB_8888 formats
Bitmap file；
Step S504 obtains the EMS memory occupation of the application memory for the destination application for currently needing to load Target Photo
Rate, judge the application memory of destination application memory usage whether be more than occupy threshold value, if it is greater than occupy threshold value, into
Enter step S505, otherwise enters step S507；
Step S505, discharging in application memory has the lower process of priority or task；
Step S506, by bitmap file recompile for Bitmap.Config.ARGB_565 formats obtain newly bitmap text
Part is stored in anonymous shared drive, is used when loading Target Photo for destination application；
Step S507, bitmap file is stored in the application memory of destination application, for destination application plus
It is used when carrying Target Photo.
By this example, implement picture load after the bitmap file of Target Photo can be made to meet loading environment again, reduces
The mortality of picture load, also, effectively avoid picture load caused by RAM leakage occur unsuccessfully now in picture loading procedure
As so that application program, which can effectively Load Image, shows corresponding application interface, promotes user experience.
