In embodiments of the present invention, can by aforementioned Hook Function after statistics unexpected message, by the unexpected message of statistics with the form transmission of broadcast, the first process then receives this broadcast, and the unexpected message of therefrom adding up processes.
In actual applications, the process sending the unexpected message of statistics by the form broadcasted is centered by ActivityManagerService.Broadcast sender by broadcast transmission to ActivityManagerService, after ActivityManagerService receives this broadcast, will check which process have subscribed this broadcast in the registration center of oneself, then this broadcast transmission in these processes.In short, the transmit path of broadcast is exactly from sender to ActivityManagerService, then from ActivityManagerService to recipient, two processes in the middle of this have all been come by Binder inter-process communication mechanisms.
In embodiments of the present invention, the broadcast that the unexpected message of the first process subscription statistics is corresponding can be set in advance in the registration center of ActivityManagerService.
Sub-step 252, after described first process receives the unexpected message of described statistics, is undertaken recording or showing by the unexpected message of described statistics.
First process, after receiving the unexpected message of statistics, can show the unexpected message of this statistics on the specific interface of the android system of correspondence.
In embodiments of the present invention, after the unexpected message receiving whole statistics that a certain APP comprises, then the unexpected message of each statistics can be shown on specific interface.Certainly, also can show the unexpected message of statistics according to other modes, to this, the embodiment of the present invention is not limited.
In embodiments of the present invention, the window of the Activity of monitoring objective application is enabled function and whether is called exception catching function, if function call exception catching function enabled by the window of Activity, then hook up described exception catching function by Hook Function, unexpected message is obtained by described exception catching function, and described unexpected message is added up, all can apply in android system, obtain the unexpected message that intended application collapse is corresponding, thus improve the comprehensive and applicability of intended application collapse statistics.

With reference to Fig. 2, show the flow chart of steps of a kind of according to an embodiment of the invention Android intended application collapse statistical method embodiment, specifically can comprise the steps:
Step 210, injects the application process of described intended application by Hook Function.
In embodiments of the present invention, the Authority Verification result that Hook Function returns for tackling Authority Verification function, performs the logical process Authority Verification result represented by checking being back to system simultaneously.So the embodiment of the present invention needs the application process first Hook Function being injected each application.
Preferably, step 210, comprising:
Sub-step 211, when system starts, initial hatching process system carried replaces with the first predetermined hatching process.
In actual applications, the normal boot process of android system is roughly: start up system->init process reads init.rc->init process creation zygote (incubator) process that starts->zygote process creation java virtual machine loading zygoteInit class-> and waits for that the establishment message->zygote process of ActivityManagerService to socket write establishment process is according to the corresponding process of described establishment message establishing by socket-> that described virtual machine registration needs are monitored.
In embodiments of the present invention, in order to realize the monitoring to each application call Authority Verification function, first initial to android system incubator process and zygote process is needed to replace, replace with the first incubator process of specifying, an i.e. zygote process, one zygote process can monitor the application process of each application the need of establishment, namely monitor aforementioned socket and whether have establishment message, if had, create this application process, this application process of function call injection is respectively hooked up by the embodiment of the present invention in constructive process, a zygote process can create one and specify process in android system simultaneously, read privately owned class in order to calling interface from assigned address and complete the read registration of privately owned class android system, the each privately owned class being about to read normal operation also can not have influence on the operation of other programs in android system.
In actual applications this application process is injected in the SO storehouse hooking up function corresponding, this SO storehouse comprises the logical code of Hook Function, thus can monitor this application process and whether call Authority Verification function.
In android system, all program process and system service process SystemServer breed (fork) out by zygote process, therefore, the present invention replaces with a zygote process by the zygote process that android system is initial and realizes monitoring and injection process.
Certainly, after the zygote process that replacement android system is initial is a zygote process, need to restart android system.The function of the zygote process after replacement, except comprising the function of initial zygote process, also added each application of monitoring and whether calls Authority Verification function.
In actual applications, Xposed framework can be utilized to realize incubator process initial for android system being replaced with the first incubator process of specifying.Wherein, Xposed framework aly can not revise APK (AndroidPackage, Android installation kit) when affect program run framework services, many powerful modules can be produced based on it, and operate when function is not conflicted simultaneously.So, in embodiments of the present invention, utilize Xposed framework, incubator process initial for android system is replaced with the first incubator process of specifying, but other original any functions of android system can not be affected.
Sub-step 212, injects the application process of described intended application by described Hook Function by described first hatching process.
Based on the logic of an aforementioned zygote process, by a zygote process, Hook Function can be injected the application process of each application.
Preferably, sub-step 212, comprising:
Whether sub-step 2121, start to start by the intended application process of intended application described in described first hatching process monitoring.
In actual applications, before each application call Authority Verification function, first need the application process starting this application, 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, if the intended application process of described intended application starts to start, then injects the application process of described intended application, completes the startup of intended application process by described Hook Function.
The essence of hook (Hook) function is one section of program in order to disposal system message, can pass through system call, its injected system.In embodiments of the present invention, when application process starts, by a zygote process, Hook Function can be injected each application process, then completes the startup of application process.
In actual applications this application process is injected in the SO storehouse hooking up function corresponding, this SO storehouse comprises the logical code of Hook Function, thus can monitor this application process and whether call Authority Verification function.
Step 220, the window of the Activity of monitoring objective application is enabled function and whether is called exception catching function; If function call exception catching function enabled by the window of Activity, then enter step 230.
Step 230, hooks up described exception catching function by Hook Function.
Step 240, obtains unexpected message by described exception catching function.
Step 250, adds up described unexpected message.
Step 260, judges whether the unexpected message of repetition; If there is the unexpected message of repetition, then enter step 270.
In actual applications, when carrying out collapse statistics for intended application, after opening an interface, tester may switch to another interface, the position of the Activity that then last interface is corresponding in stack can move down, and the Activity that the interface of new generation is corresponding can replace Activity corresponding to last interface in the position of stack top.The program that now last interface is corresponding still keeps the state run on backstage.
So, when intended application occurs extremely causing collapse, the Activity of then now corresponding with intended application display and all can simultaneously call exception catching function at the Activity of running background, then step 230-250 is performed, so will for these abnormal conditions, obtain multiple unexpected message, so in this case, the multiple unexpected messages obtained are the same simultaneously.
As can be seen here, may occur that the unexpected message obtained is the situation of repetition in actual applications, so in embodiments of the present invention, the unexpected message of repetition can be judged whether.
In embodiments of the present invention, in order to improve efficiency and the validity of follow-up performance evaluation and Optimization Work, duplicate removal process can be carried out to the unexpected message obtained.First, the unexpected message judging successively whether to have repetition in the unexpected message after adding up is needed.If there is the unexpected message repeated, then can carry out merger to the unexpected message repeated, if there is not the unexpected message of repetition, then not perform any operation.
Preferably, step 260, comprising:
Sub-step 261, judges whether that life period stabs identical unexpected message; If life period stabs identical unexpected message, then enter step 270.
Timestamp is a character string normally, identifies the time at certain a moment uniquely.In actual applications, there is the timestamp of mark acquisition time in the unexpected message utilizing exception catching function to obtain.
Unexpected message according to aforesaid repetition obtains simultaneously, timestamp so be wherein identical or difference between timestamp between each unexpected message in very little scope.So in embodiments of the present invention, preferably, can by judging whether that life period stabs identical unexpected message, or whether the difference between the timestamp judging each unexpected message is less than threshold value, such as whether be less than 1s, thus determine whether the unexpected message of repetition.
Step 270, carries out merger to the unexpected message repeated.
In embodiments of the present invention, merger just refers to the unexpected message for repeating, only retain wherein any one.In addition, in embodiments of the present invention, for the unexpected message repeated, the unexpected message read first in storage space can be only retained in, to complete the merger to repeating unexpected message.Certainly, other mode also can be adopted to carry out merger, and to this, the embodiment of the present invention is not limited.
Such as, the unexpected message that as if statistics obtains is respectively A, B, C, D, and wherein the timestamp of A with B is the same, and the timestamp of C with D is the same.
Then through step 260-270, the unexpected message finally obtained can be A or B, C or D.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 is enabled function and whether is called exception catching function, if function call exception catching function enabled by the window of Activity, then hook up described exception catching function by Hook Function, unexpected message is obtained by described exception catching function, and described unexpected message is added up, all can apply in android system, obtain the unexpected message that intended application collapse is corresponding, thus improve the comprehensive and applicability of intended application collapse statistics.
