Method.Shown in Figure 3, Fig. 3 is a kind of basic procedure schematic diagram for the method for preventing application crashes provided in this embodiment, packet
It includes:
S301: the function of each UI (User Interface, user interface) view of application is called to be tested；
It should be noted that often relating to need in application initial development and later maintenance or new version development process
Will to view each in UI method (in actual operation, method i.e. correspond to function, realized by function) operated, the operation
For Developmental Engineer, what is be allowed to is operated in main thread, but in practical projects, Developmental Engineer is past
It is careless or the case where accidentally carried out operation in sub thread toward being likely to occur, and the operation that these are carried out in sub thread
Essence be it is illegal, may result in the appearance of C or C++ layers of collapse (i.e. ncrash).It should be noted ncrash
Although appearance be caused by the operation carried out in sub thread Developmental Engineer, and it is not all in sub thread
The operation of middle progress inevitably results in the appearance of ncrash, i.e., the appearance of ncrash is sporadic, rather than must show.
It should be understood that in order to control and guarantee product quality, in application initial development and later maintenance or new version
It often can all be tested in development process, to find the various defects of product, and supervise corrective pitting.In the present embodiment,
The illegal operation that Developmental Engineer carries out in sub thread can be found in test phase, so that Developmental Engineer be supervised to repair
Change, to prevent the appearance of ncrash from the root.
S302: in test, main thread differentiation is carried out to the function of each UI view；
During the test, it would be desirable to which the method (function of i.e. each UI view) of each view in the UI of application is surveyed
Examination.When test, can method to each view whether be that the main thread operation carried out judges, and then determines that Developmental Engineer is
The no illegal operation being had in sub thread.
In the present embodiment, test when can it is conventional using Looper class by way of, using by checking
The mode of the current thread of Thread class or the thread that the function currently tested is judged using the mode that thread handle judges are
No is main thread.For using the mode of Looper class, can by with code Looper.myLooper ()！=
Looper.getMainLooper () similar code is realized；For using the current thread by checking Thread class
For mode, can by with code Thread.currentThread ()==Looper.getMainLooper ()
.getThread () similar code is realized；It, can be in advance by main line for the mode for using thread handle to judge
The Thread.currentThread () of journey gets the current handle of main thread, saves, calling when needing to judge
Thread.currentThread () compares therewith, that is, can determine whether current thread is main thread.

It can also include: to be counted to the function of each UI view, and then find out and do not carry out main thread operation before number is tested
Function, then preset mark is added in the function for not carrying out main thread operation.Main line is carried out in the function to each UI view in this way
When journey differentiates, main thread differentiation can be carried out according to function of the preset mark to each UI view.
It should be noted that the certain methods (i.e. function) itself for view will grasp main thread in system code
Judged as UI, and having certain methods then does not have, such as setScale this, it is therefore desirable to all meetings to view control
The function for being related to UI is all counted, do not have in code carry out main thread operation method find out.
It should be noted that in the present embodiment, carrying out main thread differentiation according to function of the preset mark to each UI view
It specifically may is that in the function of each UI view of detection application with the presence or absence of preset mark；If it exists, then determine currently to be differentiated
Function belong to non-master threading operation；Otherwise, it determines determining that the function currently differentiated belongs to main thread operation.It should be understood that
It is that can be in the function of each UI view of aforementioned detection application with the presence or absence of preset mark and executing the test to current function
It is preceding that detection is just first marked, but be also possible in executing the test process to current function, the function of execution is carried out
Label detection.
Especially, it should be noted that preset mark can be in a kind of feasible specific embodiment of the present embodiment
Pre-set code.And in the case where not carrying out adding pre-set code in the function of main thread operation, it can be set in the present embodiment

Pre-set code in preceding function is performed, then the implementing result of the pre-set code is that prompt is abnormal, to be directly realized by each UI
The function of view carries out main thread differentiation.
In the present embodiment, it after adding preset mark in the function for not carrying out main thread operation, can also will add
The function of preset mark is saved in database；Or the corresponding relationship of the preset mark of addition and the function is saved in database
In.It should be understood that may have found that certain bug (loophole) needs in actual use due to after initial development
Later maintenance or update are wanted, or needs to be updated application version according to actual operation, then in these later maintenance
Or it when update, is actually developed engineer and needs to modify on the basis of original function, then at this time can be straight
It connects and the corresponding preset mark of function for pre-saving each UI view in the application in the database is called to be added.
It should be understood that the scheme in above-mentioned addition database is more suitable for, there are the feelings of multiple and different preset marks
Condition.In fact, preset mark can also only be arranged one in the present embodiment, i.e., identical pre- bidding is added to all functions
Note, such benefit is that workload is smaller for test equipment, while being also more convenient for managing.
S303: when testing out a certain function and belonging to non-master threading operation, it is corresponding abnormal to record the function；
In the present embodiment, when testing out a certain function and belonging to non-master threading operation, the function is corresponding abnormal, the exception

Example, is illustrated mode of the invention.It is specific:
1, some classification are carried out to the method for view.
Main thread operation UI is judged because certain methods of view itself just have in system code, and has one
A little methods do not have then, such as setScale this, need that all counting for UI can be related to all of view control, code
In do not have main thread operate method find out.
2, Hook mechanism is introduced in our app, Hook mechanism is that one of android can cut method
It obtains, then can add the code of oneself some program.
Due to the method that we have come out the operation UI that those do not carry out main thread judgement in step 1, because
We can carry out successively hook to them for this, execute the judgement of main thread in corresponding before when hook, once
Detect that current thread belongs to non-main thread, then program can dish out corresponding abnormity prompt Developmental Engineer, allow Developmental Engineer
It is clearly visible this illegal operation for oneself having carried out updating UI in sub thread, so that Developmental Engineer can will be non-
Method operation is modified to main thread, causes to be difficult to analyzing and positioning to avoid exploitation from accidentally updating UI by sub thread with this
The appearance for the case where ncrash collapses directly fundamentally prevents occasionally existing ncrash as that must be handled first
The possibility that ncrash occurs, the working efficiency and program for improving exploitation are stablized.
