Energy equipment, this method comprises:
S201, system or application program write-in critical data failure are monitored.
S1202, judge whether the available space of data subregion is less than preset ratio value, if so, step S103 is executed,
It is no to then follow the steps S104.
S203, file is cleared up according to preset strategy, until the available space on data subregion reaches preset ratio value.
Preferably, file is cleared up according to preset strategy, until the available space on data subregion is greater than preset ratio
Value further comprises:
According to built-in SD card, application program redundant data, application data directory, application program installation directory,
The sequence of Recovery service depth cleaning carries out cleaning file, judges whether the available space of data subregion reaches in cleaning
Preset ratio value, if it is, terminating cleaning file.
As shown in figure 3, step S103 further comprises:
File built in S2031, deletion in SD card under preset path；And judge whether the available space of data subregion reaches
Preset ratio value, if it is, terminating cleaning file.
S2032, application program redundant data is deleted；And judge whether the available space of data subregion reaches preset ratio
Value, if it is, terminating cleaning file.
S2033, traversal applications program data catalogue delete size in application data directory and are greater than the first preset threshold
File；One file of every deletion judges whether the available space of a data subregion reaches preset ratio value, if it is,
Ends file cleaning.
S2034, traversal applications program installation directory delete size in application program installation directory and are greater than the second preset threshold
File；One file of every deletion judges whether the available space of a data subregion reaches preset ratio value, if it is,
Ends file cleaning.
S2035, Recovery service is called to carry out depth cleaning.
S204, restarting smart machine.
Abnormal restoring method provided in an embodiment of the present invention based on Android, by monitoring system or using journey
Sequence be written critical data to data subregion due to available space it is insufficient caused by unsuccessfully when, according to the file of deletion to the shadow of user
The degree sequence of sound carries out cleaning file Free up Memory, to solve Android system terminal due to data subregion available space
System caused by deficiency is stuck or cannot be started up.
Embodiment two
As shown in figure 4, being illustrated so that smart machine is switched on as an example, in this example, it is assumed that preset ratio value is
5%, this method comprises:
S401, smart machine booting.
S402, judge whether writing system critical data fails, if it is, terminate process, it is no to then follow the steps S403.
Specifically, it is first determined whether critical data can be normally written, if write-in critical data failure, carries out
Otherwise S403 illustrates that data subregion does not occur and writes full exception for system, terminates process.
S403, judge whether data subregion available space is greater than 5%, if it is, going to step S414, otherwise execute step
Rapid S404.
File built in S404, deletion in SD card under preset path.
Specifically, successively deleting the content in following path when deleting built-in SD card:
/data/media/0
/mnt/media_rw/sdcard0
/mnt/shell/emulated
Such case is that whole deletions are carried out to the content under these paths.
S405, judge whether data subregion available space is greater than 5%, if it is, going to step S414, otherwise execute step
Rapid S406.
S406, application program redundant data is removed.
Specifically, each application program corresponds to the data of privately owned catalogue under deletion/data/data catalogue.
S407, judge whether data subregion available space is greater than 5%, if it is, going to step S414, otherwise execute step
Rapid S408.
S408, traversal applications program data catalogue delete the file that size is greater than first threshold.
Specifically, searching loop/data catalogue, deletes big file (for example being greater than 50M).In order to be caused most to user data
Small modifications, maintenance smart machine is fully functional, and every one big file of deletion just judges primary/data subregion available space size again
Whether 5% is greater than, once available space, which is greater than 5%, can restart smart machine.
S409, judge whether data subregion available space is greater than 5%, if it is, going to step S414, otherwise execute step
Rapid S410.
S410, judge whether to have traversed application data directory, if so, thening follow the steps S411, otherwise return to step
Rapid S408.
S411, traversal applications program installation directory delete the file that size is greater than the second preset threshold.
Finished specifically, (being greater than 50M) if all big files and deleting ,/data subregion available space size still less than
5%, then/data/app catalogue is cleared up, this operation will affect the application of user oneself installation, so last delete.
S412, judge whether data subregion available space is greater than 5%, if it is, going to step S414, otherwise execute step
Rapid S413.
S413, recovery service is called to carry out depth cleaning.
Specifically ,/data subregion available space size just can only still less than 5% if having cleared up/data/app catalogue
Depth cleaning is carried out, this process will remove the critical file that system core process etc. creates in critical directories, and restore intelligence
The default setting of energy equipment, this operation will lead to user information and all remove, so as a last resort.
S414, restarting smart machine.
The present embodiment is only illustrated so that smart machine is switched on as an example, and practical applicable scene includes but is not limited to following several
Kind situation:
1) when smart machine carries out system upgrade, if/data subregion has been occupied full, upgrading finishes carry out system optimization
When need to be written critical data to/data subregion, can cause as/system exception caused by data partition space is insufficient.At this time
The system exception restoration methods can be triggered, repair system is abnormal, so that smart machine be enable normally to start.
2) due in smart machine application program possess the permission to/data subregion write-in data, if some applies journey
Sequence constantly writes data to/data subregion, will lead to/data subregion is occupied full.At this point, if system boots up or restarts,
It needs to/data subregion write-in critical data, it will cause as/system exception caused by data partition space is insufficient.At this time
The system exception restoration methods can be triggered, repair system is abnormal, so that smart machine be enable normally to start.
If 3) to/data subregion data are constantly written in application program in smart machine, cause/data subregion is occupied full,
If system is needed dynamically in the process of running to/data subregion write-in critical data at this time, can also it cause due to/data points
System exception caused by area's insufficient space.The system exception restoration methods can be triggered at this time, and repair system is abnormal, to make intelligence
Equipment can normally start.
4) if to critical positions in/data subregion data are written in application program in smart machine, lead to/data subregion quilt
It takes, if needed in system operation at this time dynamically to/data subregion write-in critical data, can also cause due to/data points
System exception caused by area's insufficient space, not only need in this case pair/data subregion under general spatial clear up, also need
System space is cleared up, the root authority file that system permission can not operate is deleted, system exception recovery can be triggered at this time
Method, repair system is abnormal, so that smart machine be enable normally to start.
