Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, with reference to embodiments, to the present invention into
Row is further to be described in detail.Described herein the specific embodiments are only for explaining the present invention, is not used to limit invention.
As shown in Figure 1, a kind of multisystem based on Android container of the present embodiment and single system switching device, comprising:
Configuration module 1 specifically includes: initialization of virtual system identifier, Process identifier for initializing cells framework
PID, automatically switch mark autoSwitch, initialization of virtual system rc file creates virtual system configuration file, data road
Diameter, carry data field and file system create virtual system list；
Master scheduling module 2, the module are the nucleus module in cells framework, and cells will be empty by different NameSpaces
Quasi- system is mutually isolated, and different virtual systems possesses different ID, different Process identifier PID and Context, it is ensured that
The Bug or malicious application run in one virtual system will not have a negative impact to other virtual systems, each virtual
System maintenance data field independent, even if the mount point of data field will not in the state that virtual system is out of service
unMount；By safeguarding the front and back operating status of virtual system, realize to the share and access of hardware device, hardware resource by
Currently running foreground virtual system is possessed；Virtual system processes PID in cells synchronous maintenance Kernel and
Context in Framework；Multiple virtual systems are communicated by the channel Socket, use message in Socket communication
The stacking of queue goes out stack mechanism；The master scheduling module is mainly used for obtaining virtual system list, increases, deletes, starting, stopping
Specified virtual system, is switched to appointing system, and safeguards virtual system according to virtual system ID, Process identifier PID or Name
State.
System switching module 3 connects for providing active switching interface on intelligent terminal when user triggers actively switching
When mouth, persist.sys.stop.vpsystem system property value changes, and when attribute value is TRUE, is switched to monosystem
System mode；When attribute value is FALSE, it is switched to multi-mode；It is main or when automatically switching mark autoSwitch opening
The performance indicators such as system meeting real-time monitoring CPU, memory, when CPU usage is more than threshold value CmaxOr memory occupation rate is more than threshold value
MmaxWhen, multi-mode is switched to single system mode, when CPU usage is not above threshold value CmaxAnd memory occupation rate does not surpass
Cross threshold value MmaxWhen, it is multi-mode by single system pattern switching.
As shown in Fig. 2, when being cut using above-mentioned apparatus progress multisystem and single system, the specific steps are as follows:
(1) after intelligent terminal booting, start cells operation in system init.rc file, configuration module 1 starts initially
Change cells framework, including mark autoSwitch, creation and initialization of virtual system configuration file and rc are automatically switched in initialization
File creates virtual system list.Each virtual system in virtual system list includes system identifier, Process identifier PID, fortune
The information such as row state.The operating status of virtual system includes starting START, operation RUNNING, activation ACTIVE, stops STOP
Etc. states.
(2) virtual system list is read, circulation reads the configuration file of each virtual system, according to the virtual system got
The configuration informations such as ID, Process identifier PID of uniting start thread creation virtual system node Node, carry data field and file system
System, operating status are set to START.The data field of virtual system and file system mounted in catalogue data/cells/ virtual system
Under the path ID/.
(3) starting thread thread1 creation Socket monitors switch switching command in real time, according in master scheduling module 2
In the instruction execution that receives create accordingly create/ destroys destroy, starting start/ stops stop, switching switch,
The operation such as setting/acquisition ID, Mount/UnMount.Wherein, creation create instruction is one new virtual system of creation, pin
Destroy instruction is ruined to destroy specified virtual system.Start start instruction for one specified virtual system of starting, virtually
System mode is to become RUNNING from START, stops stop instruction to stop a specified virtual system, virtual system shape
State becomes STOP from RUNNING.After the foreground virtual system for being currently at ACTIVE state is is placed in by switching switch instruction
Platform operation, operating status become RUNNING from ACTIVE；By the backstage virtual system in specified RUNNING operating status
It is placed in front stage operation, operating status becomes ACTIVE from RUNNING.It is virtual in synchronous maintenance Kernel when virtual system switches
Context in system process PID and Framework.
(4) starting thread thread2 creation Socket monitors persist.sys.stop.vpsystem system category in real time
Property, when attribute value is TRUE, start user's switching module 3, the virtual system ID that current operating conditions are ACTIVE saved,
And the instruction for stopping stop virtual system and switching switch main system, the operation of all virtual systems are sent to master scheduling module
State becomes STOP, and the operating status of main system becomes ACTIVE.When attribute value is FALSE, start user's switching module 3,
Starting start virtual system is sent to master scheduling module and switches the instruction of switch virtual system, and main system operating status becomes
Virtual system operating status for STOP, preservation becomes ACTIVE, remaining virtual system operating status becomes RUNNING.
(5) when automatically switching mark autoSwitch is TRUE, starting thread thread3 creates Socket real-time monitoring
The performance indicators such as CPU, memory.When currently for multisystem operation and CPU usage be more than threshold value CmaxOr memory occupation rate is more than threshold
Value MmaxWhen, the virtual system ID that current operating conditions are ACTIVE is saved, and virtual to master scheduling module transmission stopping stop
The instruction of system and switching switch main system, the operating status of all virtual systems become STOP, the operating status of main system
Become ACTIVE.When currently for single system and CPU usage is lower than threshold value CmaxAnd memory occupation rate is lower than threshold value MmaxWhen, to master
Scheduler module sends starting start virtual system and switches the instruction of switch virtual system, and main system operating status becomes
The virtual system operating status of STOP, preservation become ACTIVE, remaining virtual system operating status becomes RUNNING.Wherein Cmax
And MmaxIt can be configured by system property.
Summary, the present invention can provide the solution that multisystem/single system coexists and switches for intelligent terminal, user made to exist
User can have both been allowed to be switched to multisystem under the higher scene of safety with flexible choice on scene compatibility and functional requirement
Mode can also be switched to single system mode in the case where the performance indicators such as the CPU of intelligent terminal, memory are bad, entirely cut
It will not cause the loss of data during changing.
The limitation that technical solution of the present invention is not limited to the above specific embodiments, it is all to do according to the technique and scheme of the present invention
Technology deformation out, falls within the scope of protection of the present invention.
