Method provided in this embodiment is primarily adapted for use in Android (Android) system.Android system is a kind of in not
The open source system of disconnected evolution state, there are multiple and different versions, and different version android systems is in and deposits
State.Method provided in this embodiment is suitable for the version of 2.2 or more Android, and applicable range is big.
In order to be compatible with the version of 2.2 or more Android, can all be had using the version of 2.2 or more Android
OnUpdate method trigger above-mentioned process reclaimer operation, and start to be polled, determine whether to recycle some process.
In general, the four big basic modules that android system all has are Activity (activity), Service respectively
(service), ContentProvider (content provider), BroadcastReceiver (radio receiver), separately below to this
Four components are introduced.
Firstly, Activity is the concept of a user interface, Activity usually indicates a screen in application program
Curtain.It generally comprise one or more View (View is user interface element, be constitute user interface basic building block,
View can be a button, label, the text field or various other user interface elements), however, you can also not include View.
The meaning of this word of Activity and it itself is much like: helping user to complete a certain operation, this operation may be to look at number
According to, creation data or editor data.Multiple Activity are owned by most of Android application program.
Service in Android is similar to the service in Windows (window) or other platforms, they are all possible
The background process of long-play.Android defines two kinds of Service: local Service and long-range Service.
Local Service is the component that can only be accessed by the application program for carrying the Service.And long-range Service is in equipment
The Service of the other applications remote access of upper operation.Email application is used for the component of poll new mail, just
It is a Service example.If the other applications that this Service cannot be run in equipment use, it
It is exactly local Service.If there is multiple application programs use the Service, then it is exactly long-range Service.
Android is that application program defines a kind of standard mechanism and comes shared data (such as contacts list), without public affairs
Open bottom storage, structure and realization.By ContentProvider application program can be allowed to use and come from it with public data
The data of his application program.
Android application program can be used BroadcastReceiver and be filtered to external event, only to interested
External event (e.g., when phone incoming call or when data network is available) received and responded.
BroadcastReceiver does not have user interface, however, they can star an Activity or Serice to respond them
The information received, or user is notified with NotificationManager (notice management class).Notice can use many kinds side
Formula attracts the attention of user, such as flashes back light, vibration, plays sound, in general can put one on status bar
Lasting icon, user can open it and obtain message.
Four big basic modules, which require registration, to be used, each Activity, Service, ContentProvider
It needs to be configured in AndroidManifest file.It is not stated in AndroidManifest file
Activity, Service and ContentProvider will not be system finding, thus it is also just unavailable, and
The registration point static registration (being configured in AndroidManifest file) of BroadcastReceiver and pass through code
Dynamic creation is simultaneously registered to system in a manner of calling Context.registerReceiver ().It should be noted that
The BroadcastReceiver configured in AndroidManifest file can be constantly in active with the starting of system
State, even if program not running, as long as receiving interested broadcast will trigger.
Operation Android application program and its process of component can undergo various life cycle events (Android application journey
The life cycle of sequence is to be managed by Android frame, rather than directly controlled by application program), Android is provided back
It adjusts, by realizing that they can handle state change.
By taking the various life cycle callbacks of an Activity as an example, the life cycle callback method of Activity is as follows:
onCreate()、onStart()、onRestart()、onResume()、onPause()、onStop()、onDestroy
().It is illustrated in figure 2 the state transition diagram of Activity.
System can start and stop Activity according to other events of generation.Just when creation Activity,
Android calls onCreate () method, then can always call onStart (), but calls not total before onStart ()
It is to call onCreate (), because can stop in application program and (call calling onStart () after onStop ()).Work as tune
When with onStart (), Activity is invisible to user, but later will be visible.After calling onStart (),
Activity is in foreground and calls onResume () when can access for user, and at this moment, user will interact with Activity.
When user determines to go to another Activity, system will call onPause () method of current Activity,
Then onResume () or onStop () can be capable of calling.For example, will be called if current Activity is recalled to foreground by user
onResume().If Activity becomes invisible to user, onStop () will be called.Before if Activity has been recalled to
Platform, then after calling onStop () onRestart () will be called.If Activity is located in Activity stack, but
It is invisible to user, and system decision terminates the Activity, then onDestroy () will be called.
It triggers process reclaimer operation by onUpdate method and is polled and need suitable opportunity, that is, need that conjunction is arranged
Suitable preset process recycles event, and the present embodiment provides several preferred preset processes recycling events, including it is following at least
One of: application program launching event, system component starting event, system component exit event, component destruction event, it is counter register into
Cheng Huishou interface management class event.
Application program launching event, system component starting event, system component exit event, component destruction event actually
All reflected that the operating status of current system is changed, then at this time with regard to need judge certain processes whether be can
With recycling, to save system resource.In order to trigger the process reclaimer operation of poll as far as possible, counter will be registered in the present embodiment
Process recycles interface management class event and also recycles event as a kind of optional preset process.
The attribute information for each component mentioned in the above method is primarily referred to as the current state information of each component, below into
Row detailed description.
Fig. 3 shows the method according to an embodiment of the invention for determining whether to be recycled current process
Flow chart.As shown in figure 3, this approach includes the following steps S302 to step S306.
Step S302 judges with the presence or absence of the component being resumed in each component run in current process, if so, continuing
Execute step S304；Otherwise, step S306 is continued to execute.
In this step, the component being resumed is the component for being in front stage operation, can also judge current process indirectly
With the presence or absence of the component for being in front stage operation in each component of interior operation.
Step S304 is determined to current process without recovery processing.
In this step, the component being resumed is in the state of front stage operation, then not to the process where the component into
Row recycling.
Step S306, determination are recycled current process.
It in this step, can be to when advance if there is no the components being resumed in each component run in current process
Cheng Jinhang recovery processing can also further be judged using the subsequent method referred to.
In an embodiment of the present invention, count area each process in application program can be arranged (as worked as application program
In process initiation when, the count area of the process is set), for the group for being resumed component in the process and/or being suspended
Part is counted.For example, when receiving component recovery event (i.e. calling onResume () callback method), to what is be resumed
The count area of process increases count value where component；(onPause () readjustment side is called when receiving component suspending event
Method) when, count value is reduced to the count area of process where the component being suspended.
Counting by taking Activity component as an example, when receiving Activity component recovery event, to process where it
Field mResumedActivityCount increases count value, such as 1 or 2；When receiving Activity component suspending event,
Count value, such as 1 or 2 are reduced to the count area mResumedActivityCount of process where it, the present invention does not do this
Limitation.
Based on to the count area of each process setting in application program, the embodiment of the invention provides a kind of implementations above
The optinal plan of above step S302 can read the count area of current process in this scenario, and then judge count area
Count value whether be greater than specified threshold, there is the component that is resumed in each component run in current process if so, determining；
If not, it is determined that there is no the components being resumed in each component run in current process.
The embodiment of the invention also provides the another kind scheme that selectively determines whether to be recycled current process,
Fig. 4 shows the process of the method in accordance with another embodiment of the present invention for determining whether to be recycled current process
Figure.As shown in figure 3, this method at least includes the following steps S302 to step S306.
Step S402 judges whether current process is null process or background process, if so, continuing to execute step S404；
Otherwise, step S406 is continued to execute.
In this step, the identifier of current process can be first obtained, searches the identifier of current process in systems
RunningAppProcessInfo (information for the process that the interface encapsulation is currently running), calls its importance field.
If the field value is IMPORTANCE_EMPTY, then it represents that current process is null process；If the field value is
IMPORTANCE_BACKGROUND, then it represents that current process is background process.
Step S404, determination are recycled current process.
Step S406 is determined to current process without recovery processing.
In this step, if current process is not null process or background process, can to current process without recycling at
Reason, can also be using method shown in Fig. 3 or the subsequent method referred to further judge above.
In an embodiment of the present invention, the component that cannot be recovered can be registered in specified class.In an application program
It is interior, usually possess one or more Activity, Service, ContentProvider, BroadcastReceiver, is answering
During being run with program, for the component that cannot be recovered, it can be registered in specified class.For example, self defined class
IKillable, it is impossible to which for the component register being recovered into the self defined class, it has a method isKillable (), is sentencing
When whether disconnected component needs to be recovered, this method isKillable () can be called, by this method isKillable () lookup group
Whether part is registered in the self defined class, if this method returns to false, then it represents that component register is into the self defined class, the group
Part cannot be recovered.If this method return true, then it represents that component is not registered in the self defined class, can recycle the component or
Person continues through other methods and judges whether to recycle the component.
Based on specified class above, the embodiment of the invention also provides another kind selectively determine whether to current process into
The scheme of row recycling, Fig. 5 show another embodiment according to the present invention and determine whether to be recycled current process
Method flow chart.As shown in figure 5, this method at least includes the following steps S502 to step S506.
Step S502, judges whether each component run in current process is registered in specified class, if fortune in current process
There are at least one component registers into specified class in capable each component, then continues to execute step S504；If fortune in current process
There is no component registers into specified class in capable each component, then continues to execute step S506.
In this step, the judgment method that specified class can be called, it is each by being run in judgment method lookup current process
Whether component is registered in specified class, and then receives the lookup result that judgment method returns, and is determined whether back according to lookup result
Receive current process.
Step S504 is determined to current process without recovery processing.
Step S506, determination are recycled current process.
It in this step, can be right if there is no component registers into specified class in each component run in current process
Current process is recycled, and can not also be recycled using conservative scheme, can be using Fig. 3's or Fig. 4 above
Method further judges.
In practical applications, can be determined whether using Fig. 3, Fig. 4 or Fig. 5 method shown in any one to current process into
Row recovery processing can also determine whether to be recycled current process, example in conjunction with Fig. 3, Fig. 4 and method shown in fig. 5
Such as, there is no the components being resumed in each component run in current process, and in each component run in current process not
When there are component registers into specified class, determination is recycled current process.
When current process is multiple processes, can be judged respectively for each process, with determine whether to its into
Row recovery processing, details are not described herein again.
The method for carrying out process recovery processing in the application of the invention is discussed in detail with a specific embodiment below
Realization process.
In this embodiment, the customized class being related to is as follows:
1)IKillable
One interface.It has a method, isKillable ()
isKillable
Search whether the components such as Activity or Service are registered in IKillable, if this method returns to false,
Component register is indicated into IKillable, which cannot be recovered.If this method returns to true, then it represents that component is unregistered
Into IKillable, the component can be recycled or continue through other methods judge whether to recycle the component.
2)KillableMonitor
For managing the class of all IKillable interfaces, i.e., above-mentioned recovery processing interface management class, including it is typical
List<IKillable>。
registerKillable(IKillable)
It is added IKillable interface object (mKillableSet) into List.
unregisterKillable(IKillable)
It deletes IKillable interface object (mKillableSet) into List.It is anti-every time in order to trigger poll as far as possible
A MESSAGE_TRY_KILL_PROCESS (a kind of process reclaimer operation) can be all initiated when registration immediately, can be moved back in time in this way
UI process out.
isAllKillable()
It judges whether there is IKillable.isKillable and returns to false.As long as there is any one, this cannot be recycled by meaning that
Process.
3)KillerHandler
It is inherited from Handler, for handling event: MESSAGE_TRY_KILL_PROCESS
MESSAGE_TRY_KILL_PROCESS
This method is used to call tryKillProcess.Since Handler uses the mode of poll, every between setting time
It walks every (such as 1 minute) once, until the event is terminated.
4)ProcessKiller
Core classes, for dispatching the life and death of entire process.Including method:
onUpdate
MESSAGE_TRY_KILL_PROCESS event is only initiated, automatically into poll once initiating.
However, in triggering scene this method need to be called in following scenario:
Activity.onDestroy (each)
When application program launching
Other possible situations
init()
