Embodiment 1
See Fig. 2, in order to realize shortening Android operation system start-up time, the present invention includes following setting:
Step 101: start Android device, performs boot, loads linux kernel by boot; Perform the loading of Android user's space resource again, local service is opened and user partition is scanned, namely based on the initialization of existing Android operation system completion system.
Step 102: after having loaded class needed for Android virtual machine and resource by Zygote process, interrupt Zygote process (the procr_freeze_process function (this function has pre-service audit function) provided by the storehouse libprocr.so of system is cut off interrupt clock and blocked coherent signal to freeze Zygote process)
Step 103:
(1) function provided by storehouse libprocr.so completes and creates the restoration point of Zygote process, and namely after calling the related function that storehouse libprocr.so provides, process will be Zygote process creation restoration point:
In this step, based on the file structure of the current Android operation system file obtained, for restoration point file writes the header information (be restoration point file and arrange the indications that can be identified by storehouse libprocr.so) that can be identified by storehouse libprocr.so.
After the preload () function of Zygote process, add procr_request_check () built-in function, this function sends signal to kernel and makes Zygote process be absorbed in kernel for oneself establishment restoration point file (in the present embodiment, restoration point file designation is Zygote.procr); First the file directory of restoration point file is specified, in the present embodiment, be set to/data/, then the internal memory execution environment information of current Zygote process link information, Zygote process ID, CPU status information, Zygote process, signal information (gauge outfit file, for arranging the respective action of a certain signal) are saved in created restoration point file;
(2) restoration point file checking process (the present embodiment called after procr process) is created, and procr process is set loads after linux kernel in boot and start, for whether there is the restoration point file of above-mentioned setting under judgement/data/, if exist, then according to restoration point file, Zygote process is reduced; Otherwise perform Zygote process based on existing mode.
In the present embodiment, the setting of procr process is specially:
Write file procr.sh: first whether there is process restoration point file under inspection/data/.If existed, reduction Zygote process; Otherwise, create procr process, and by procr process creation Zygote process, perform Zygote process based on existing mode.
Procr.sh file is put into/system/bin catalogue under and revise its authority for performing, amendment init.rc script (function that initialize process performs in this script logging) makes system first create procr process before establishment Zygote process.
Individual in the present embodiment, when carrying out reduction treatment according to restoration point file to Zygote process, recovered the internal memory execution environment information of Zygote process ID, CPU status information, Zygote process according to restoration point file content by the proc_restart program (/system/bin/proc_restart-f/data/Zygote.procr//recovering process state) of procr process.Proc_restart is put into/system/bin catalogue under be modified as and can perform authority, and original Zygote.procr will be gone back be kept at/data catalogue under, be read-only authority.Zygote process resumption after running status, can continue at restoration point place run thus skip class consuming time and the preloading phase of resource, achieves the quick startup of system.
Step 104:Zygote process completes restoration point and creates, if Zygote process continues to run and finally successfully enters Android user interface the success of backup Zygote process restoration point file is described, otherwise enters step 102 and again backs up;
In this step, Zygote process completes after restoration point creates and returns to procr process, first the interrupt clock cut off is opened and again the signal recuperation of blocking is come, more whether continuation operation subsequent processes (to enter Android user interface) backs up the success of Zygote process to test.
Android device after above-mentioned setting, user, after startup Android is equipment, first performs boot, loads linux kernel by boot, open in the loading of execution Android user's space resource, local service and after the scanning of user partition, then perform procr process; First process procr can check/data/ under whether there is restoration point file, if not, then re-create Zygote process by procr process and enter existing start-up mode; If, then enter fast attack mode of the present invention (entering Android user interface according to going back after Zygote process is carried out running status reduction rear execution subsequent processes by original), namely continue at restoration point place run thus skip class consuming time and the preloading phase of resource, achieve the quick startup of system.
Embodiment 2
The set-up mode of embodiment 1 being set up the setting about postponing installation kit, Delay Service, being specially:
In a step 101, according to user's request investigation pick out user be of little use or system start after the installation kit that can not be used immediately by user and service, be defined as and postpone installation kit, Delay Service, remaining is defined as and starts installation kit, starts service;
Then delay installation kit, Delay Service are moved on to user partition from system partitioning, thus realize the temporary occlusion init.rc script (function that initialize process performs in this script logging) to inessential service;
In this step, we provide concrete embodiment to block service A.First, in init.rc script, code is added:
On property:ro.user.start＝1
Start A
In init.rc script file, record the action will taked after certain attribute changes, the executive condition of action provides with " onproperty:<key>=LEssT.LTssT. LTvalue> " form.After the key assignments that certain executive condition is relevant is set, the trigger relevant to this condition will be triggered.As implied above, when ro.user.start property value is set to 1, A service will be activated.
Finally, start delay installation kit and service after Android operation system has started, in the present embodiment, adopt and apply (in the present embodiment called after Delayinit.apk) by the Android customized, select user inactivity state start blocked service and the bag of user partition is installed.In this step, by the application of the Android of customization---Delayinit.apk adds system.After system has started, Android Application Framework can send an Intent message to Delayinit.apk, called after BOOTCOMPLETED Intent.For above-mentioned service A, Delayinit.apk receive about service A intent message after can select user inactivity state arrange ro.user.start attribute be 1 and wake up init process open service A.When user is in inactivity state, Delayinit.apk also can call " PM " instrument and go to scan the installation kit installing user partition.Described " PM " instrument is provided by Android operation system, its can implicit expression call scanning and the installment work that Package Manager system service completes installation kit and service in particular zones (the present embodiment is user partition).
Recovery Zygote process of the present invention is to the difference of specific executing state and the existing sleeping/waking technology based on ARM Hibernation: Zygote process resumption brings into operation to restoration point place the preloading phase not influential system renewal of applying having merely skipped class and resource, therefore need the quantity of information of recovery few, recover rapidly.And the existing sleeping/waking technology based on ARMHibernation can skip Android user's space start even linux kernel start, although saved the start-up time being skipped part, but need containing much information of recovery, recover consuming time, and recover to cause upgrading system application from the image file of backup at every turn.
Adopt the method described in embodiment 1, the process initiation temporal information normally being started by the collection of BootChart instrument and start fast.During normal startup, from Zygote process creation to having loaded class and about 18 seconds resource used time; During quick startup, complete this process only about 4 seconds used time.
Adopt the method described in embodiment 2, the process initiation temporal information normally being started by the collection of BootChart instrument and start fast.When not adopting delay technology, be built into from SystemServer process and finally enter user interface, about 10 seconds used time; After adopting delay technology, complete this process only about 5 seconds used time.
