Comprising large number of rows and many column informations in the standard output result of PS, each of which row one process of correspondence,
Be classified as a field per each in a line, for correspondence process is described a feature (for example：Process name
Title, process user, process ID, etc.), but substantial amounts of reality is included in the standard output result of PS
The unwanted information in border is (for example：The progress information of some invalid system process), and the core of the application
Part is to construct in the version with Andoid below 5.0 as object RunningApprocessInfo
Process list, so needing further to perform step S102-S105.
Step S102：Based on a filtering rule, to output result in whole progress informations filter.
In specific implementation process, the principle of filtering is the progress information for leaving consumer process, rejects some nothings
The progress information of the system process of effect, while need to retain some system process (for example again：System is pre-installed
App progress information).Specific filtering rule is as follows：
(1) if the process user in the first progress information (i.e.：User) opened with the first preset characters string
The user of head, then retain first progress information；Wherein, the first progress information is complete in output result
Any progress information in portion's progress information, the first preset characters string is " u0_ " or " u1_ " or " app_ ".
If that is, the title of the user of a certain progress information be " u0_ ", " u1_ ", " app_ " beginning,
Then corresponding process is the process of user App processes or most of built-in App certainly, so needing to retain
The progress information.
(2) if the process user in the first progress information (i.e.：User) it is system, and first enters
It is comprising the first preset characters but also pre- not comprising second not comprising the second preset characters in the process title of journey breath
If character string, then retain first progress information；Wherein, the first progress information is complete in output result
Any progress information in portion's progress information, the first preset characters are " ", and the second preset characters are "/", second
Preset characters string is " system_ ".That is, the progress information for being system for user, then exclude
Fall into journey title containing "/" (for example：/ system/) and " system_ " is (for example：system_server)
With there is no the progress information of " " in process title.For example：The entitled com.android.systemui of process
Progress information meet the requirements, retain；Process is entitled/the process letter of system/bin/su or zygote
Breath is not inconsistent requirement, excludes.
(3) if the process user of the first progress information (i.e.：User it is not) system nor with
The user of one preset characters string beginning, and in the process title of the first progress information comprising the first preset characters but
Not comprising the second preset characters, then retain first progress information；Wherein, the first progress information is output
Any progress information in whole progress informations in result, the first preset characters string be " u0_ " or " u1_ ",
Or " app_ ", the first preset characters are " ", and the second preset characters are "/".If that is, process is believed
User in breath be other situations (for example：Root, nfc etc.), then exclude in process name containing "/" but
There is no the progress information of " ".For example：The progress information of the entitled com.android.phone of process meets
It is required that, retain；The progress information of the entitled radio of process is not inconsistent requirement, excludes.
Step S103：Every progress information after filtering is parsed, the every process letter after being filtered
Whole fields that breath is included.
As a kind of optional embodiment, when step S103 is performed, String.split can be directly used
Method, parses to every progress information after filtering.But, String.split inside has used canonical
Expression formula is realized, less efficient.After tested, using String.split parsing needs for up to more than 200
Millisecond.
As a kind of preferred embodiment, when step S103 is performed, because the output result of PS orders is
One field for arranging, it is possible to every progress information after scanning filtering, writes down every after filtering and enters
Each in journey information becomes the position for turning to nonblank character from NUL (i.e.：Opening for field is determined
Beginning position), and each is become from NUL turn to position of nonblank character and save as array array；Using number
The index of group, intercepts each and becomes the character string turned to after the position of nonblank character from NUL, so as to obtain
The whole fields included in every progress information after must filtering.After tested, parse what is needed using this method
Time only needs more than 70 milliseconds, and efficiency is higher, can meet actual demand.
Step S104：Predetermined word is extracted in the whole fields included from every progress information after the filtering
Section.
, it is necessary to construct the object in Andorid below 5.0 in version in specific implementation process
RunningApprocessInfo, so the preset field extracted as object herein
The field included in RunningApprocessInfo, including：Process title is (i.e.：processName)、
Process user is (i.e.：User), process ID is (i.e.：Pid), ID is (i.e.：Uid), process is used
Bag list of file names (i.e.：PkgList), process material information is (i.e.：importance).
In specific implementation process, process can be extracted from the first row in every progress information after filtering
User is (i.e.：User) field；Process can be extracted from the secondary series in every progress information after filtering
ID is (i.e.：Pid) field；Can from the last first row in every progress information after filtering, extract into
Journey title is (i.e.：ProcessName) field.
In specific implementation process, android.os.Process.getUidForName functions can be called, obtained
The ID in every progress information after must filtering is (i.e.：Uid) field.
In specific implementation process, the bag where every progress information after filtering being based on, it is determined that filtering
The bag list of file names that the process in every progress information afterwards is used is (i.e.：PkgList) field.That is,
