OK, may comprise steps of：
Step 210, monitors selective recovery Default Value broadcast.
Selective recovery Default Value broadcast be for notifying terminal user to need to carry out selective recovery to go out
Factory is arranged.Based on this, terminal unit, will in order to be known when user needs to carry out selective recovery Default Value in time
Selective recovery Default Value broadcast is monitored.
Further, when user has carried out the selection behaviour of selective recovery Default Value in the operation interface of terminal unit
When making, selective recovery Default Value broadcast is generated and is broadcasted, and then it is extensive to cause terminal unit to listen to the selectivity
Multiple Default Value broadcast.
Step 230, when selective recovery Default Value broadcast is listened to, obtains user in CONFIG.SYS
Retention data, and store to relief area.
When selective recovery Default Value broadcast is listened to, terminal unit has known that user needs to be selected
Property factory reset.
So-called selective recovery Default Value refers to not carry out user data subregion entirely in factory reset
Disk is Physical Formatting, and only the user data of the non-selected reservation of user is purged.Therefore, dispatch from the factory carrying out selective recovery
Before setting, need to carry out the acquisition of user's retention data, to know that user selects the user for retaining by user's retention data
Which data have.
CONFIG.SYS is generated when user carries out the selection operation of selective recovery Default Value, is wherein preserved
The content related to the selection operation carried out by user, i.e. user's retention data.
For example, represent the selective listing for being available for user's selection in operation interface, the selective listing includes media number
According to the option such as, account and password, contact person, application and corresponding application data, if user have selected contact people option, generate
CONFIG.SYS in preserve user's retention data be contact people option.
Thus, user's retention data will be obtained by CONFIG.SYS.After user's retention data is obtained, you can will
User's retention data is stored to relief area, in order to carry out follow-up selective recovery Default Value.
Step 250, in being serviced by calling system, predefined selective recovery Default Value service, divides to user data
User data in area conducts interviews, and executes terminal according to the user's retention data in relief area to the user data having access to
The selective recovery Default Value of equipment.
Predefined selective recovery Default Value service is available for application layer and calls, in order to execute according to user's retention data
The selective recovery Default Value of terminal unit.
After storing user's retention data in the buffer, you can carry out the predefined selective recovery Default Value
Serviced calls, to realize the selective recovery Default Value of terminal unit.
Specifically, no matter whether terminal unit is in encrypted state, by vold process automatically carry user data
Subregion, realizes the access to the user data in user data subregion.After user data is had access to, you can according to relief area
In user's retention data carry out selective clearing to the user data having access to, that is, retain the use involved by user's retention data
User data, removes the user data of the non-selected reservation of user.
By process as above, it is achieved that the selective recovery Default Value of terminal unit in application layer, i.e., at end
End in encrypted state when, by vold process automatically carry encryption user data subregion, and then indirectly to encryption
The access of user data in user data subregion, extensive with the selectivity that this user data that realizes to having access to executes terminal unit
Multiple Default Value, it is to avoid in prior art terminal unit in encrypted state when, the user data in user data subregion is no
Method is accessed and causes the problem of selective recovery Default Value disabler.
On the other hand, due to having carried out the predefined of selective recovery Default Value service, the selection not only can be defined
Property factory reset service need execute function, and can be the selective recovery Default Value service definition rank relatively
High execution authority, thus avoid terminal unit in prior art carries out also needing to exploitation during selective recovery Default Value respectively
Plant and execute authority and cause the affected problem of security of system.This can not only reduce because lack corresponding execution authority and
User data is caused to remove the probability of failure, while the user data for also reducing the more privacy such as user account, password is stolen
The risk for taking, it is ensured that the safety of user's using terminal equipment.
Fig. 3 is referred to, in one exemplary embodiment, before step 210, method as above can also include following
Step：
Step 310, intercepts and obtains triggering the selective recovery Default Value instruction for generating.
Selective recovery Default Value entrance will be set up for selective recovery Default Value function in terminal unit, if user
Need terminal unit that selective recovery Default Value is carried out, will be clicked in the selective recovery Default Value entrance accordingly
Operation.
After the clicking operation that user is completed in the selective recovery Default Value entrance, generate in terminal unit
Corresponding selective recovery Default Value instruction, and then terminal unit is intercepted obtain the selective recovery Default Value and refer to
Order.
Certainly, in other embodiments, existing factory reset entrance can also be utilized in terminal unit, to carry out
What the factory reset that triggering is generated was instructed intercepts.Intercept obtain the factory reset instruction when, by operation circle
Show in face that selective listing carries out the acquisition of user's retention data.If user's retention data is got, selectivity is subsequently carried out
Factory reset, if not getting user's retention data, subsequently carries out factory reset.
Step 330, obtains, according to the instruction of selective recovery Default Value, user's retention data that triggering is generated.
After terminal unit is intercepted and obtains the instruction of selective recovery Default Value, further will open up in the operation interface
Existing selective listing, so that user selects which the user data for retaining required for which has.
For example, the selective listing in operation interface includes media data, account and password, contact person, applies and corresponding
The data options such as application data, user is completed selective recovery and goes out by clicking on the contact people option in the option list
The selection operation that factory is arranged.
After user completes the selection operation of selective recovery Default Value, terminal unit is obtained to be entered with user
Content, i.e. user's retention data of the selection operation correlation of row.In other words, user's retention data is the choosing for being carried out by user
Select what operation triggering was generated, what which represented is only the data options related to user data, for example, user's retention data is contact
People option.
Step 350, user's retention data is stored in CONFIG.SYS, generates and broadcast selective recovery and dispatch from the factory setting
Put broadcast.
After user's retention data is obtained, you can in preserving user's retention data to CONFIG.SYS.More preferably,
The storage format of CONFIG.SYS is json, improves the storage efficiency of user's retention data with this.
When user's retention data is preserved, selective recovery Default Value broadcast is will additionally generate, and then by broadcast
The selective recovery Default Value broadcast so that terminal unit is by monitoring the selective recovery Default Value broadcast
Know that user needs to carry out selective recovery Default Value.
Fig. 4 is referred to, in one exemplary embodiment, before step 250, method as above can also include following
Step：
Step 410, before the shutdown process that terminal unit is entered executes the unloading of user data subregion, in parsing relief area
Identify with the presence or absence of selective recovery Default Value.
Selective recovery Default Value will be carried out in shutdown process, and terminal can be entered by calling the interface of restarting of itself
Enter shutdown process, the power-off operation that can also be triggered by responding user enters shutdown process.
For example, terminal unit will be made by calling the interface of restarting of itself before selective recovery Default Value is carried out
Obtain terminal unit and enter shutdown process.
Specifically, restart interface to be called, corresponding reset command in terminal unit, can be got, and then by response
Reset command is executed restarts.
It should be appreciated that restart including shutdown process and starting up's flow process, based on this, after response reset command, whole
End equipment initially enters shutdown process.
Further, as selective recovery Default Value needs to visit the user data in user data subregion
Ask, therefore, after shutdown process is entered, selective recovery Default Value will be carried out before the unloading of user data subregion, with
Avoid because terminal unit can not find user data subregion and cause the failure of user data selective clearing.
Further, before the unloading of user data subregion is executed, whether terminal unit will be to carrying out selective recovery
Default Value makees to judge, when avoiding user from carrying out selective recovery Default Value with this, terminal unit has carried out unnecessary
Process.
Wherein, selective recovery Default Value mark is generated when user's retention data is stored to relief area.Change and
Yan Zhi, selective recovery Default Value mark is generated when terminal unit listens to selective recovery Default Value broadcast
, which may be used to represent that user needs to carry out selective recovery Default Value.
Therefore, whether terminal unit is to carrying out the judgement of selective recovery Default Value by whether depositing in parsing relief area
Realize in selective recovery Default Value mark.
If there is selective recovery Default Value mark in relief area, step 250 is entered so that terminal unit is by adjusting
Selective recovery Default Value with predefined selective recovery Default Value service execution terminal unit in system service.
If conversely, there is no selective recovery Default Value mark in relief area, terminal unit executes existing shutdown
Flow process and starting up's flow process.
By process as above, it is achieved that the selective recovery Default Value in shutdown process, it is to avoid transport
The application of row causes the problem of application crashes because its corresponding user data is eliminated, and effectively further improves user's
Experience.
On the other hand, before selective recovery Default Value is carried out, selective recovery Default Value mark is carried out first
Parsing, avoid terminal unit from carrying out unnecessary process with this, so as to be effectively improved the treatment effeciency of terminal unit.
Fig. 5 is referred to, in one exemplary embodiment, step 250 may comprise steps of：
Step 251, is serviced by selective recovery Default Value is obtained in system service.
As it was previously stated, terminal unit needs to predefine in calling system service to carry out selective recovery Default Value
Selective recovery Default Value service.
Therefore, before the calling of selective recovery Default Value service is carried out, terminal unit will be by entering in system service
The acquisition of row selective recovery Default Value service.
Step 253, calls the retention data Processing Interface in the service of selective recovery Default Value, is parsed by relief area
Go out user's retention data, and the user's retention data to parsing carries out process formation script file of classifying.
After the service of selective recovery Default Value is got, will be by calling in the service of selective recovery Default Value
Predefined interface executes the selective recovery Default Value of terminal unit.
As user's retention data is the content related to the selection operation carried out by user, which is based primarily upon mankind's language
Speech, to be convenient to user's understanding, and terminal unit needs to make which be based on machine language in order to which is used, to be convenient to
Terminal unit is executed.
For this purpose, predefined interface includes retention data Processing Interface, the retention data Processing Interface is in order to buffering
User's retention data in area is parsed and classification is processed, so that the user after terminal unit can better profit from processing protects
Residual is according to execution selective recovery Default Value.
Further, after user's retention data completes to parse and classification is processed, terminal unit will be also made after process
User's retention data dynamic formation script file, for example, terminal unit can call existing Linux command to carry out script file
Dynamic generation, with the speed of this accelerating selection factory reset, shorten the time of selective recovery Default Value, so as to
The treatment effeciency of terminal unit is further improved.
Step 255, is input into using script file as interface, calls the selectivity in the service of selective recovery Default Value extensive
Multiple Default Value interface carries out selective clearing to the user data in user data subregion.
Further, predefined interface also includes selective recovery Default Value interface, and the selective recovery goes out
Factory arranges interface in order to execute selective recovery Default Value.
Specifically, after according to the user's retention data dynamic formation script file after process, will be with the script file
It is input into as interface, and selective clearing is carried out to the user data in user data subregion according to the script file of input,
Retain the user data in script file involved by user's retention data, remaining user data is removed, terminal is completed with this and is set
Standby selective recovery Default Value.
By process as above, when terminal unit is in encrypted state, the user data that encrypts can not only be divided
User data in area conducts interviews, and without the need for executing authority accordingly according to the user data exploitation that removes, both ensure that
Security of system, it is ensured that terminal unit executes the success rate of selective recovery Default Value.
Fig. 6 is referred to, in one exemplary embodiment, before step 251, method as above can also include following
Step：
Step 510, retention data Processing Interface and selective recovery Default Value interface defined in interface statement.
Step 530, goes out according to retention data Processing Interface and selective recovery Default Value interface definition selective recovery
Factory arranges service.
As it was previously stated, terminal unit needs selectivity in calling system service to carry out selective recovery Default Value
Factory reset is serviced.
The selective recovery Default Value service is to execute the service of selective recovery Default Value in order to terminal unit, can
To understand, before this, selective recovery Default Value service is not there are in system service, needs to be defined which, can
Call for application layer.
Selective recovery Default Value function includes two parts：A part is to obtain user's retention data, so that terminal sets
Which the standby user data for knowing that user's needs retain has；Another part is the choosing for executing user data according to user's retention data
Selecting property is removed, and then completes selective recovery Default Value.
Based on this, in interface statement, retention data Processing Interface and selective recovery Default Value interface is carried out respectively
Definition, with by enabling two interfaces to be called the definition of two interfaces, and then realizes selective recovery and dispatches from the factory
Function is set.
After interface definition is completed, you can carry out selective recovery Default Value service by two interfaces for defining
Definition so that by calling selective recovery Default Value service, that is, complete in selective recovery Default Value service
The calling of above-mentioned two interface.
Step 550, selective recovery Default Value service is added to system service.
After selective recovery Default Value service completes definition, you can add it in system service, so that eventually
End equipment can be by getting the selective recovery Default Value service, and then by calling the selective recovery in system service
Selective recovery Default Value function is realized in Default Value service.
By process as above, it is achieved that it is predefined that selective recovery Default Value is serviced, not only so that selecting
Property factory reset can be realized based on application layer, with this avoid terminal unit in encrypted state when recovery pattern
Down cannot carry user data subregion problem, and enable the selective recovery Default Value service that higher level is set
Execution authority, avoided with this also need to when terminal unit carries out selective recovery Default Value to develop various execution authorities and
Cause the affected problem of security of system.
Fig. 7 is a kind of flow chart of the method for terminal unit factory reset in application scenarios.
As shown in fig. 7, user passes through execution step 601, confirm selective recovery Default Value is executed, select which to need to protect
The user data for staying so that terminal unit gets corresponding user's retention data.
Terminal unit passes through execution step 602, preserves user's retention data in CONFIG.SYS, while generating and wide
Broadcast selective recovery Default Value broadcast so that terminal unit passes through execution step 603, listens to the selective recovery and goes out
Factory arranges broadcast, and then causes terminal unit to pass through execution step 604, and selective recovery Default Value is identified and user
Retention data is stored respectively to relief area.
After the storage for completing relief area, terminal unit passes through execution step 605, restarts interface acquisition weight by calling
Order is opened, and by responding reset command to enter shutdown process.
Before shutdown process executes the unloading of user data subregion, terminal unit passes through execution step 606, judges relief area
In with the presence or absence of selective recovery Default Value identify, if not existing, enter step 607 so that terminal unit is directly executed
Restart.
If conversely, existing, step 608 is entered, the service of selective recovery Default Value is obtained, and passes through execution step
609, call predefined interface in the service of selective recovery Default Value to execute the choosing of the user data in user data subregion
Selecting property is removed, and completes selective recovery Default Value function with this.
After selective recovery Default Value function is completed, terminal unit is executed by execution step 610 restarts.
In embodiments of the present invention, in being serviced by calling system, predefined selective recovery Default Value service, right
