Embodiment one
The embodiment of the present application provides a kind of method for preventing Activity life cycle exception, this prevents Activity life
The method of period exception is applied to electronic device, which can be the tool such as smart phone, tablet computer, wearable device
The equipment of the standby function of preventing Activity life cycle exception, the operating system of above-mentioned electronic device can be ios,
Android, windows system or other operating systems, are not construed as limiting herein.
Referring to Fig. 1, the method for preventing Activity life cycle exception mainly includes the following steps that 101 to step
103:
Step 101, the state of monitor process.
Generally, a process includes creation, ready, execution, obstruction and terminates five states such as (or terminations).Process
State can be called by process manager monitors function to obtain, and monitors function when calling, the return value of the parameter obtained
Show state of a process.
If step 102, monitored process have terminated, detect whether to rebuild the process that terminated.
By taking android system as an example, the process that terminated is created again, and a scene is not have enough time moving due to AMS
Remove or clear up the related data of the process of termination.Therefore, after process termination, a detection can be done, to determine whether weight
Build this process that terminated.Specifically, if process manager detects that process creation function is called, and parameter therein is institute
State the title or mark of the process of termination, it is determined that this process that terminated is created again.
The process if step 103, reconstruction have terminated forces the Activity for returning to stack top portion carrying out recovery operation, with
The Activity of recovery is corresponded into the foreground that user interface is shown in terminal.
It remarks additionally herein to the life cycle of the Activity of android system.The life of so-called Activity
Period refers to Activity various states experienced from start to end, that is, turns from a state to another state
Become, arrive nothing again from scratch, such a state experienced in the process is just called life cycle.Android is using task
(Task) Activity is managed, a task is exactly the one group of Activity being stored in stack set, this stack is referred to as
Return to stack.Except irrevocable stack is at sky, always there is an Activity to be in and return to stack top portion, in return stack top portion
Activity is in operating status, the Activity only through over recovery (resume) this operation, corresponding user interface
The foreground of terminal, user's ability normal use, for example, carrying out human-computer interaction can be just shown in.Rebuild in order to prevent terminated into
The generation of user interface exception when journey is forced to restore the Activity for returning to stack top portion in the embodiment of the present application
(resume) it operates, before the corresponding user interface of the Activity (i.e. resumed Activity) restored is shown in terminal
Platform.
From the exemplary method for preventing Activity life cycle exception of above-mentioned attached drawing 1 it is found that the technical solution of the application
When reconstruction has terminated process, forces the Activity that will return to stack top portion to carry out recovery operation, exist with existing android system
AMS be not yet in time for cleaning terminated process related data but rebuild the process, since AMS is not to current Activity
Relevant operation is executed, user interface is caused to be compared extremely, the technical solution of the application is forced due to taking to return stack top portion
Activity carry out recovery operation measure, thus it is guaranteed that current system always have an Activity be in restored shape
The Activity of recovery is corresponded to user interface and is shown in terminal by state so that the life cycle of Activity be allowed to be in normal
Foreground.
Embodiment two
Attached drawing 2 is the method that Activity life cycle exception is prevented described in another embodiment of the application, specific to wrap
Step 201 is included to step 204, detailed description are as follows:
Step 201, the state of monitor process.
Term, concept that step 201 is related to etc. are identical as term, the concept that the step 101 of 1 example of attached drawing is related to etc.,
Realization process is also identical, can refer to the description of previous embodiment, is not repeated herein.
If step 202, monitored process have terminated, detect whether to rebuild the process that terminated.
Term, concept that step 202 is related to etc. are identical as term, the concept that the step 102 of 1 example of attached drawing is related to etc.,
Realization process is also identical, can refer to the description of previous embodiment, is not repeated herein.
The process if step 203, reconstruction have terminated, obtains triggering and rebuilds the reason of having terminated process.
Either creation process still rebuilds the process of termination for the first time, can be realized by process creation function, and
The value of some parameters in process creation function is practical to may indicate that the reason of triggering creation process, therefore, at the present invention one
In embodiment, acquisition triggering is rebuild the reason of having terminated process and be can be by calling process creation function, according to process creation
It is any in Activity, broadcast reception device assembly, serviced component or the content supplier's component that the value of parameter includes in function
One kind determining that the reason of having terminated process is rebuild in triggering.For example, for the program that Java language is write,
In the startProcessLocked function of ActivityManagerServcice.java file, it is called with one
The parameter of hostingType, the value of this parameter be exactly service, broadcast, content provider or
Activity can be determined according to this parameter and be rebuild the reason of having terminated process, for example, if the value of parameter is
Broadcast, then trigger reconstruction terminated process the reason of be to start this component of radio receiver.
If step 204, triggering rebuild terminated process the reason of be starting broadcast reception device assembly, starting serviced component or
Start any one in content supplier's component, then will return to stack top portion when removing the related data for process of being killed
Activity carries out recovery operation.
By taking Andriod system as an example, Andriod system mainly has radio receiver (Broadcast Receiver), uses
Family interface (Activity), the service four big components such as (Service) and content supplier (Content Provider), triggering wound
It builds whether the reason of having terminated process starts this four components nothing more than, i.e., whether is starting radio receiver, starting
Activity, starting service or starting content supplier.
If due to rebuilding the process that terminated being starting this component of Activity, stack top portion will obviously will be returned to
Activity carry out recovery operation, there is no the problems of the life cycle of Activity exception in this case.However, if
The reason of having terminated process is rebuild as appointing in starting radio receiver, starting service or starting these three components of content supplier
When anticipating a kind of, for background technique, the life of Activity is then likely to occur when removing the related data for process of being killed
Period is abnormal.Therefore, rebuild terminated process the reason of for starting radio receiver, starting service or starting content supplier this
When any one in three components, the Activity that stack top portion will be returned to when removing the related data for process of being killed is carried out
Restore (resume) operation, the corresponding user interface of the Activity (i.e. resumed Activity) restored is shown in terminal
Foreground.
From the exemplary method for preventing Activity life cycle exception of above-mentioned attached drawing 2 it is found that the technical solution of the application
The reason of having terminated process is rebuild in confirmation triggering to start radio receiver, starting service or starting content supplier etc. three
When any one in component, the Activity for returning to stack top portion is restored when removing the related data for process of being killed
Operation, with existing android system AMS be not yet in time for cleaning be killed process related data but rebuild should be into
Journey causes user interface to be compared extremely, the technical side of the application since AMS does not execute relevant operation to current Activity
Case is due to taking the measure for forcing to carry out recovery operation to the Activity for returning to stack top portion, thus it is guaranteed that current system
Always there is an Activity to be in and restored state, to allow the life cycle of Activity to be in normal, by recovery
Activity corresponds to the foreground that user interface is shown in terminal.
Embodiment three
Attached drawing 3 is the method that Activity life cycle exception is prevented described in another embodiment of the application, specific to wrap
Step 301 is included to step 305, detailed description are as follows:
Step 301, the state of monitor process.
Term, concept that step 301 is related to etc. and the step 201 of 2 example of step 101 or attached drawing of 1 example of attached drawing are related to
Term, concept etc. it is identical, realize that process is also identical, can refer to the description of previous embodiment, be not repeated herein.
If step 302, monitored process have terminated, detect whether to rebuild the process that terminated.
Term, concept that step 302 is related to etc. and the step 202 of 2 example of step 102 or attached drawing of 1 example of attached drawing are related to
Term, concept etc. it is identical, realize that process is also identical, can refer to the description of previous embodiment, be not repeated herein.
The process if step 303, reconstruction have terminated, forbids the process of having terminated to send broadcast message before being terminated.
As previously mentioned, a loophole existing for Android native system is, and if some process is terminated, before being terminated,
The process can issue a broadcast message and need itself processing, and AMS can restart the process when the process sends and broadcasts the message.
AMS can also handle the work of some data scrubbings after old process is terminated during restarting process, be not carried out at this time
Resume returns to the Activity this operation in stack top portion, and then no one of leads to system Activity is to be in
Resumed state causes user to use abnormal.Therefore, if the process of having terminated is forbidden to send broadcast message before being terminated,
It is not in the above problem.Since broadcast message is to send function by broadcast message to realize, wherein there is an enabled parameter, when
The enabled Parameter then can normally send broadcast message when calling the parameter when being set as " enabling ", conversely, if being set as
Broadcast message then cannot be sent when calling the parameter when " make cannot ", therefore, as one embodiment of the invention, is forbidden eventually
Knot process sends the broadcast message transmission letter that broadcast message can be process manager for broadcast transmission process before being terminated
Several enabled parameters is set as making cannot.
Step 304, the process termination notice for waiting the process that terminated.
For process after termination, system can send the process termination notice of the process, and AMS waits the process for the process that terminated whole
Knot notice, this is the primary process of android system, is not repeated them here.
Step 305, the process of having terminated process termination notify reach when to return stack top portion Activity execute it is extensive
Multiple operation.
After executing recovery operation to the Activity for returning to stack top portion, current system just has the Activity of a reply
(i.e. resumed Activity), it is meant that this Activity restored is corresponded to before user interface can be shown in terminal
Platform.
From the exemplary method for preventing Activity life cycle exception of above-mentioned attached drawing 3 it is found that the technical solution of the application
When confirmation rebuilds and terminated process, broadcast message is sent before being terminated by forbidding rebuilding the process that terminated, and it is existing
Android system AMS not yet be in time for cleaning terminated process related data but rebuild the process, since AMS does not have
Relevant operation is executed to current Activity and user interface is caused to be compared extremely, the technical solution of the application is directly forbidden eventually
Knot process sends broadcast message before being terminated, with the process termination for the process of having terminated notify reach when to return stack top portion
Activity execute recovery operation, thus it is guaranteed that current system always have an Activity be in restored state, thus
It allows the life cycle of Activity to be in normal, the Activity of recovery is corresponded into the foreground that user interface is shown in terminal.
Example IV
Attached drawing 4 is the method that Activity life cycle exception is prevented described in another embodiment of the application, specific to wrap
Step 401 is included to step 406, detailed description are as follows:
Step 401, the state of monitor process.
Term, concept that step 401 is related to etc. and the step 101 of 1 example of attached drawing, the step 201 or attached drawing of 2 example of attached drawing
Term, concept that the step 301 of 3 examples is related to etc. are identical, realize that process is also identical, can refer to retouching for previous embodiment
It states, is not repeated herein.
If step 402, monitored process have terminated, detect whether to rebuild the process that terminated.
Term, concept that step 402 is related to etc. and the step 102 of 1 example of attached drawing, the step 202 or attached drawing of 2 example of attached drawing
Term, concept that the step 302 of 3 examples is related to etc. are identical, realize that process is also identical, can refer to retouching for previous embodiment
It states, is not repeated herein.
The process if step 403, reconstruction have terminated, obtains triggering and rebuilds the reason of having terminated process.
Either creation process still rebuilds the process of termination for the first time, can be realized by process creation function, and
The value of some parameters in process creation function is practical to may indicate that the reason of triggering creation process, therefore, at the present invention one
In embodiment, acquisition triggering is rebuild the reason of having terminated process and be can be by calling process creation function, according to process creation
It is any in Activity, broadcast reception device assembly, serviced component or the content supplier's component that the value of parameter includes in function
One kind determining that the reason of having terminated process is rebuild in triggering.For example, for the program that Java language is write,
In the startProcessLocked function of ActivityManagerServcice.java file, it is called with one
The parameter of hostingType, the value of this parameter be exactly service, broadcast, content provider or
Activity can be determined according to this parameter and be rebuild the reason of having terminated process, for example, if the value of parameter is
Broadcast, then trigger reconstruction terminated process the reason of be to start this component of radio receiver.
If it is starting broadcast reception device assembly that step 404, triggering, which rebuild the reason of having terminated process, forbid to having terminated
The related data of process, which executes, removes operation.
As one embodiment of the invention, forbid that the related data for the process of having terminated is executed to remove to operate to pass through process
Creation function obtains the title or mark of the process that terminated, and according to the record of title or mark to the process of having terminated, jumps
The calling to the process data cleaning function that terminated is crossed to realize.By taking Android as an example, in startProcessLocked function
In, if obtaining the terminated title or mark of process by process creation function, discovery currently terminated process in AMS
There is the record of a same names or mark, and already existing process has been recorded and has terminated, then exists
HandleAppDiedLocked will be called to go to do clearly already existing process record in startProcessLocked function
Reason, judged according to parameter hostingtype, do not done in this process handleAppDiedLocked can, i.e.,
The related data for the process of having terminated is not executed and removes operation.
Step 405 waits the necrology for process of being killed to reach.
For process after termination, system can send the process termination notice of the process, and AMS waits the process for the process that terminated whole
Knot notice, this is the primary process of android system, is not repeated them here.
Step 406, the process of having terminated process termination notify reach when to return stack top portion Activity execute it is extensive
Multiple operation.
After executing recovery operation to the Activity for returning to stack top portion, current system just has the Activity of a reply
(i.e. resumed Activity), it is meant that this Activity restored is corresponded to before user interface can be shown in terminal
Platform.
From the exemplary method for preventing Activity life cycle exception of above-mentioned attached drawing 4 it is found that the technical solution of the application
When confirmation triggering rebuilds the reason of having terminated process to start this component of radio receiver, forbid the phase to the process of having terminated
Data are closed to execute removal operation and the process termination of the process of termination is waited to notify to reach, it is logical in the process termination for the process of having terminated
Know and recovery operation is executed to the Activity for returning to stack top portion when arrival, is not yet in time for clearly with existing android system in AMS
It manages the related data for the process that terminated but rebuilds the process, led since AMS does not execute relevant operation to current Activity
User interface is caused to compare extremely, the technical solution of the application, which forbids executing the related data for the process of having terminated, removes operation, with
Recovery operation is executed to the Activity for returning to stack top portion when the process termination for the process of having terminated notifies to reach, thus it is guaranteed that
Current system always has Activity to be in have restored state, so that the life cycle of Activity is allowed to be in normal, it will
The Activity of recovery corresponds to the foreground that user interface is shown in terminal.
