It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
Embodiment one
Referring to Fig.1, show that a kind of Android intended application collapse statistical method according to an embodiment of the invention is implemented
The step flow chart of example, can specifically include following steps：
Step 110, the window of the Activity of monitoring objective application enables whether function calls exception catching function；If
The window of Activity enables function call exception catching function, then enters step 120.
Above-mentioned intended application may include each application for needing to obtain crash info run in android system,
Such as 360 security guards, 360 secure browsers.
It is also most commonly seen one of four big components that Activity, which is most basic in Android components, and Activity is
One application component, provides a screen, and user can be used for interaction to complete a certain task.In an Android
In, an Activity is exactly usually an individual screen, it can show that some controls can also be monitored simultaneously above
The event of processing user responds.In practical applications, an Activity is included at least in an application.
Exception catching function, i.e. UncaughtException functions are the exceptions for obtaining corresponding intended application collapse
The function of message, in practical applications, unexpected message may include cause intended application crash reason, it is specific in the application
Position etc..In embodiments of the present invention, as unit of Activity, the window of the Activity of monitoring objective application enables letter
Whether number calls exception catching function.If the window of the Activity of intended application enables function call exception catching function,
120 can be then entered step, and if the window of the Activity of intended application enables function never call exception catching function,
Any step is not executed.
In practical applications, it for an APP, if to start an Activity of the APP, needs first to call
The Activity run functions of system, i.e. OnCreate functions, then execute subsequent operation.OnCreate functions are a message
Receptance function is in response to a function of WM_CREATE message, and WM_CREATE message is by Create function calls.
OnCreate functions mainly do some necessary initial works when this Activity starts, after this function call is complete, this
A Activity is not to say that and just has been started up, or jumps to foreground.But other extensive works are also needed to, we
Know：There are onRestart functions and onStart functions etc. after onCreate.Actually onStart function calls finish
This Activity not yet completely start, also only foreground as it can be seen that after onResume function calls this OnCreate
It just calculates and starts completely.
Step 120, the exception catching function is hooked up by Hook Function.
In embodiments of the present invention, UncaughtException functions can be hooked up using Hook Function, then no matter mesh
Whether UncaughtExceptionHandler is had been carried out in mark application, can be continued to execute for intended application
The window of Activity enables the logic that exception catching function is hooked up in function.So as to so that external process can be to target
The unexpected message of application is counted.
In practical applications, if the window for monitoring the Activity of intended application enables function, i.e. OnCreate functions,
Exception catching function is called, then shows that intended application occurs abnormal and causes to collapse at this time, then can trigger calling Hook Function
Hook up exception catching function.
Step 130, unexpected message is obtained by the exception catching function.
As above-mentioned, the effect of exception catching function is to obtain the unexpected message for causing intended application to be collapsed, so in this hair
In bright embodiment, after hooking up exception catching function using Hook Function, can be obtained by exception catching function causes target to be answered
With the unexpected message of collapse.
Step 140, the unexpected message is counted.
In practical applications, the unexpected message of acquisition can be counted according to current system time, and be stored in
In message queue, then the message queue can also be sent to the first process, then remembered by the first process according to demand
Record or carry out subsequent displaying.It is of course also possible to be counted and stored otherwise, not to this embodiment of the present invention
It is limited.
Preferably, after step 140, further include：
The unexpected message that statistics obtains is sent to the first process by sub-step 251 in the form of broadcasting.
In embodiments of the present invention, statistics unexpected message is executed by the application process of intended application, if that wanting
The unexpected message obtained to statistics is handled, then needs other process.Broadcast can be utilized so in the embodiment of the present invention
Form the obtained unexpected message of statistics is sent to the first process, the first process then receives the unexpected message that statistics obtains, right
It is recorded or is shown.
It in embodiments of the present invention, can be by aforementioned Hook Function after counting unexpected message, by the unexpected message of statistics
It is sent in the form of broadcast, the first process then receives the broadcast, and the unexpected message therefrom counted is handled.
In practical applications, in the form of broadcast send statistics unexpected message process be with
Centered on ActivityManagerService.The sender of broadcast by broadcast transmission to ActivityManagerService,
After ActivityManagerService receives this broadcast, it will check which process is ordered in the registration center of oneself
The broadcast is read, then in this broadcast transmission to these processes.In short, the transmitting path of broadcast is exactly from sender
To ActivityManagerService, then from ActivityManagerService to recipient, this two intermediate process
All completed by Binder inter-process communication mechanisms.
In embodiments of the present invention, first can be set in the registration center of ActivityManagerService in advance
Process subscribes to the corresponding broadcast of unexpected message of statistics.
Sub-step 252, after first process receives the unexpected message of the statistics, by the unexpected message of the statistics
It is recorded or is shown.
First process, can be on the specific interface of corresponding android system after receiving the unexpected message of statistics
Show the unexpected message of the statistics.
In embodiments of the present invention, can receive the unexpected message all counted that a certain APP is included and then
The unexpected message of each statistics is shown on specific interface.It is of course also possible to the unexpected message of statistics is shown otherwise,
In this regard, the embodiment of the present invention is not limited.
In embodiments of the present invention, the window of the Activity of monitoring objective application enables whether function calls exception catching
Function hooks up the exception by Hook Function and catches if the window of Activity enables function call exception catching function
Function is obtained, unexpected message is obtained by the exception catching function, and the unexpected message is counted, can be directed to
It is all applied in android system, obtains intended application and collapse corresponding unexpected message, to improve intended application collapse system
The comprehensive and applicability of meter.
Embodiment two
With reference to Fig. 2, show that a kind of Android intended application collapse statistical method according to an embodiment of the invention is implemented
The step flow chart of example, can specifically include following steps：
Step 210, Hook Function is injected in the application process of the intended application.
In embodiments of the present invention, Hook Function is used to intercept the Authority Verification of Authority Verification function return as a result, simultaneously
The logical process that system is back to by the Authority Verification result verified will be indicated by executing.So the embodiment of the present invention needs elder generation
Hook Function is injected in the application process of each application.
Preferably, step 210, including：
Sub-step 211, when system starts, by system carry initial hatching process replace with scheduled first hatch into
Journey.
In practical applications, the normal boot process of android system is substantially：Activation system->Init processes are read
Start init.rc->Init process creations zygote (incubator) process->Zygote process creation java virtual machines are loaded into
ZygoteInit classes->The socket-monitored is needed by virtual machine registration>It waits for
The establishment message-of establishment process is written to socket by ActivityManagerService>Zygote processes are according to the establishment
Message establishing corresponds to process.
In embodiments of the present invention, in order to realize the monitoring to each application call Authority Verification function, it is right first to need
The initial incubator process, that is, zygote processes of android system are replaced, and replace with the first specified incubator process, i.e.,
Whether the first zygote processes, the application process that the first zygote processes can monitor each application need to create, that is, before monitoring
State whether socket has establishment message, if there is then creating the application process, by each of the embodiment of the present invention during establishment
The function call injection application process is hooked up, while the first zygote processes can create a specified process in android system,
Privately owned class is read from designated position to calling interface and complete registration of the read privately owned class in android system, i.e.,
Each privately owned class of reading normal operation can will not be influenced into the operation of other programs in android system.
The corresponding libraries SO of function will be hooked up in practical applications and inject the application process, which includes patrolling for Hook Function
Code is collected, so as to monitor whether the application process calls Authority Verification function.
In android system, all program process and system service process System Server be all by
Zygote processes breed (fork) come out, therefore, the present invention can be replaced with by the initial zygote processes of android system
First zygote processes realize monitoring and injection process.
Certainly, it after replacing the initial zygote processes of android system and being the first zygote processes, needs to restart
Android system.The function of replaced first zygote processes is other than the function including initial zygote processes, also
It is added to whether each application of monitoring calls Authority Verification function.
In practical applications, Xposed frames can be utilized to realize to replace the initial incubator process of android system
For the first specified incubator process.Wherein, Xposed frames be it is a can not change APK (AndroidPackage, peace
Tall and erect installation kit) in the case of influence program operation framework services, many powerful modules can be produced based on it, and
In the case where function does not conflict while operating.So in embodiments of the present invention, using Xposed frames, by Android systems
The incubator process for uniting initial replaces with the first specified incubator process, but does not interfere with original its of android system
His any function.
Sub-step 212, by the first hatching process by the Hook Function inject the application of the intended application into
Cheng Zhong.
Based on the logic of aforementioned first zygote processes, Hook Function injection can respectively be answered by the first zygote processes
In application process.
Preferably, sub-step 212, including：
Whether sub-step 2121, the intended application process for hatching intended application described in process monitoring by described first start
Start.
In practical applications, before each application call Authority Verification function, it is necessary first to start the application of the application into
Journey, and then application process can be utilized to call Authority Verification function.
In embodiments of the present invention, can by the first application process that respectively apply of hatching process monitoring whether start.
Sub-step 2122 notes the Hook Function if the intended application process of the intended application starts to start
Enter the application process of the intended application, completes the startup of intended application process.
The essence of hook (Hook) function is one section of program to processing system message, can be called by system,
Its injected system.It in embodiments of the present invention, can be when application process starts, by the first zygote processes, by Hook Function
It injects in each application process, then completes the startup of application process.
The corresponding libraries SO of function will be hooked up in practical applications and inject the application process, which includes patrolling for Hook Function
Code is collected, so as to monitor whether the application process calls Authority Verification function.
Step 220, the window of the Activity of monitoring objective application enables whether function calls exception catching function；If
The window of Activity enables function call exception catching function, then enters step 230.
Step 230, the exception catching function is hooked up by Hook Function.
Step 240, unexpected message is obtained by the exception catching function.
Step 250, the unexpected message is counted.
Step 260, the unexpected message of repetition is judged whether there is；If there is the unexpected message repeated, then 270 are entered step.
In practical applications, when carrying out collapse statistics for intended application, after opening an interface, tester can
Another interface can be switched to, then positions of the corresponding Activity in previous interface in stack can move down, newly generated interface pair
The Activity answered can replace the corresponding Activity in previous interface in the position of stack top.The corresponding program in previous interface is still at this time
So in the state remained operational from the background.
So when intended application occur it is abnormal lead to collapse when, then display corresponding with intended application at this time
Activity and exception catching function can be all called simultaneously in the Activity of running background, then execute step 230-250,
The abnormal conditions will be so directed to, while obtaining multiple unexpected messages, then in this case, acquired multiple exceptions
Message is the same.
It can be seen that in practical applications it is possible that the unexpected message obtained is the case where repetition, so in this hair
In bright embodiment, the unexpected message of repetition is determined whether.
It in embodiments of the present invention, can be right in order to improve the efficiency and validity of subsequent performance evaluation and Optimization Work
The unexpected message of acquisition carries out duplicate removal processing.Firstly, it is necessary to judge whether there be the different of repetition in the unexpected message after statistics successively
Normal message.If there is the unexpected message repeated, merger can be carried out to the unexpected message repeated, if there is no the exceptions repeated to disappear
Breath, then do not execute any operation.
Preferably, step 260, including：
Sub-step 261 judges whether the identical unexpected message of timestamp；Disappear if there is the identical exception of timestamp
Breath, then enter step 270.
Timestamp is typically a character string, uniquely identifies the time at certain a moment.In practical applications, exception is utilized
It captures and there is the timestamp that mark obtains the time in the unexpected message that function obtains.
It is obtained simultaneously according to the unexpected message of repetition above-mentioned, then timestamp therein is identical or each
The difference between timestamp between unexpected message is to a very small extent.So in embodiments of the present invention, it is preferable that can be with
By judging whether the identical unexpected message of timestamp, or judge whether is difference between the timestamp of each unexpected message
Less than threshold value, than such as whether less than 1s, determining whether the unexpected message of repetition.
Step 270, merger is carried out to the unexpected message repeated.
In embodiments of the present invention, merger refer to just for repeat unexpected message, only retain wherein any one.Separately
Outside, in embodiments of the present invention, for the unexpected message repeated, it can only be retained in and be read for the first time in memory space
Unexpected message, to complete the merger to repeating unexpected message.It is of course also possible to use other modes carry out merger, in this regard, this
Inventive embodiments are not limited.
For example, it is assumed that the obtained unexpected message of statistics is respectively A, B, C, D, wherein A as the timestamp of B, C and D's
Timestamp is the same.
Then pass through step 260-270, finally obtained unexpected message can be A or B, C or D.Such as, A, C or A, D or B,
C or B, D.
In embodiments of the present invention, the window of the Activity of same monitoring objective application enables whether function calls exception
Function is captured, if the window of Activity enables function call exception catching function, is hooked up by Hook Function described different
Often capture function obtains unexpected message by the exception catching function, and the unexpected message is counted, and can be directed to
It is all applied in android system, obtains intended application and collapse corresponding unexpected message, to improve intended application collapse system
The comprehensive and applicability of meter.
Moreover, in embodiments of the present invention, original in android system incubate is replaced using specific first hatching process
Change process injects Hook Function in each intended application of android system to realize, and is respectively answered using Hook Function monitoring
With whether exception catching function is called, if then hooking up exception catching function using Hook Function, the then exception by hooking up
It captures function and obtains unexpected message, all applied so as to be directed in android system, it is corresponding to obtain intended application collapse
Unexpected message further improves the comprehensive and applicability of intended application collapse statistics.
In addition, in embodiments of the present invention, by judging that statistics obtains disappearing with the presence or absence of the exception repeated in unexpected message
Breath, and the unexpected message to repeating carries out merger, to realize the duplicate removal processing to unexpected message, so as to reduce
The repetitive rate of acquired unexpected message improves validity, and can also improve the efficiency of follow-up test personnel analysis.
For embodiment of the method, for simple description, therefore it is all expressed as a series of combination of actions, but this field
