In the Android system of offer of the present invention Launcher be operating abnormally restoration methods, in Android system
The main Activity and spare Activity of built-in Launcher attribute in the APK of Launcher.The main Activity is used for
Launcher starts when being in normal, and the spare Activity starts when being in abnormal for Launcher.It is described spare
Activity is only to provide system list of application and entrance, does not influence the normal use of whole equipment.Also, it is described spare
The priority of Activity is higher than main Activity, and the original state of spare Activity is disabling.It can be by preparatory
It is configured in the allocation list of Android system, the original state of spare Activity is provided with disabling, is existed in this way
When Launcher normally starts, starting is to live in Activity in available mode.Meanwhile the excellent of spare Activity is set
First grade is higher than main Activity, when arriving Launcher exception in this way, sets available for the state of spare Activity, again
When starting Launcher, since the priority of spare Activity is higher than main Activity, to start spare Activity.It keeps away
Exempt to repeat when main Activity is in abnormal, the main Activity of repeated priming causes Launcher repeated priming, Wu Fazheng
The problem of being often used.
The Launcher is the desktop starter in Android system, and the desktop UI of Android system is referred to as Launcher.
The Activity is an application component in android system, provides a screen, and user can be used to
Interaction is in order to complete a certain task.All operations are all closely related with user in Activity, are one and are responsible for interacting with user
Component.
The APK is for AndroidPackage, i.e. Android installation kit.
With reference to the accompanying drawing, by the description of the embodiment, further explanation of the contents of the invention are made.
Referring to Figure 1, Fig. 1 provides the restoration methods that Launcher is operating abnormally in Android system for the present invention and preferably implements
The flow chart of example.The described method includes:
S100, starting Launcher process, listen to Launcher and are operating abnormally event.
Specifically, the starting Launcher process can be intelligently sets in mobile phone, tablet computer, television set, wrist-watch etc.
It is standby to be switched on and start Launcher process.After Launcher process initiation, one can be created for listening to Launcher fortune
The thread A of row anomalous event listens to Launcher by thread A and is operating abnormally event.The Launcher is operating abnormally event
In the starting of Launcher process and in use process, the generation of operation exception event all might have.Here operation is different
Ordinary affair part refers mainly to the class anomalous event out of service for lacking the generations such as necessary configuration or setting due to running environment, e.g.,
Null pointer is abnormal, writes data exception, reads data exception etc..Due to directly be cut off using meeting, nothing once this exception occurs
Method continues to run, constant to the use agency of user.
In the present embodiment, the Launcher that listens to is operating abnormally the callback method progress that event is carried using Android system
It listens to.Such as: Thread.setDefaultUncaughtExceptionHandler (new
UncaughtExceptionHandler())；When being operating abnormally event there are Launcher, it will adjust back
The uncaughtException of UncaughtExceptionHandler.And exception can be carried out in this callback method
The setting of label etc..
S200, when listening to Launcher and being operating abnormally event, setting Launcher is operating abnormally the abnormal mark of event
Will position, and the state of spare Activity is changed to can be used, restart Launcher process.
Specifically, it is that boolean one by one is arranged that the setting Launcher, which is operating abnormally the abnormality mark position of event,
The variable of type, value are true or false.When value is true, specification exception flag bit exists, and when value is false, says
Bright abnormality mark position is not present.Meanwhile it can be by the state of Activity spare in the configuration file prestored in Android system more
It is changed to available mode, and restarts Launcher.In this way, each service in Android system is activated to and can be realized interface
When initialization, the configuration file prestored in Android system is read.In turn, higher spare according to configuration file starting priority
Activity avoids main Activity repeated priming, Launcher starter is caused to restart, and influence that user uses asks
Topic.
Further, in order to avoid user is not available desktop for a long time, Launcher operation exception event will be listened to and arrived
The time of restarting Launcher shortens as far as possible, so that abnormality mark position is only set when noting abnormalities event, it will be described different
Ordinary affair part reports server.But in order to which producer or research staff can quickly understand the Launcher anomalous event,
After restarting Launcher, the Launcher anomalous event is reported into server.It can pass through abnormal log
Formation reports server, that is, generates abnormal log when setting up abnormality mark position, by Launcher anomalous event
When reporting server, abnormal log is reported into server.Ze You producer or research staff incite somebody to action according to abnormal log modification program
Amended program formulates new upgrade package, is uploaded to server.Abnormal problem can be solved by online upgrading in this way, greatly
Reduce and return factory and lead and rate of visiting after sale.
When there is no when exception excessively, that start when starting Launcher process is all Activity by Launcher.But
It is if Launcher occurred extremely, when starting Launcher process, starting may be spare Activity.And it is standby
It is fairly simple with the function of Activity, without the feature-rich of active Activity, then how to judge Launcher exception
Whether modification is also the major issue to bring convenience to the users.To be wrapped in Launcher process initiation
A verification process is included, judges Launcher with the presence or absence of abnormal.

Judge whether there is abnormality mark position.It is, being to judge Launcher process by the value for the variable for detecting boolean type
It is no to be transmitted across exception, to start main Activity or spare Activity to determine.
S20, in the presence of abnormality mark position, obtain the current version number of the Launcher；And judge current version number
Whether change, if current version number does not change, starts spare Activity.
Specifically, the version number that current version number refers to obtaining currently running Launcher installation kit is obtained.And sentence
Whether disconnected current version number, which changes, refers to that the version number for running current version number with last time one is compared, if one
It causes, then current version number is to change；If it is inconsistent, current version changes.That is, Launcher process
In each starting, the version number of the Launcher installation kit of this starting is all obtained, and the version number is stored.In next time
When starting Launcher, obtain the version number of current operation Launcher installation kit, and by its version number with last time operation into
Row compares, if version number is identical, it is constant to save version number, if version number is not identical, with the version number of this operation
Update the version number saved.It is of course also possible to when starting Launcher is carried out every time, all using the Launcher of this operation
The version number of installation kit updates existing version number.

When the anomalous event for judging Launcher process whether solve, and affixed one's name to upgrade installation package in server internal.To open
Moving spare Activity can also include later a detection process.It is specifically as follows: after starting spare Activity,
Whether the timer of starting setting predetermined time, dispose upgrade package at interval of predetermined time detection service device, services when detecting
When device disposes upgrade package, upgrade package is downloaded and installed, is then shut off timer, restarts Launcher process.That is,
In the case where starting spare Activity, retrieve whether a server disposes upgrade package, Zhi Daojian at interval of the predetermined time
After rope to upgrade package, upgrade package is downloaded and installed, then stops retrieval.In this way can to avoid when starting main Activity,
The problem of whether continuous retrieve disposes upgrade package, temporary system resource, causes system Caton.
If S30, current version number change, the abnormality mark position of clearing systems anomalous event, and will be described spare
The state of Activity is changed to disable, and restarts Launcher process.
Specifically, if current version number changes, then illustrate that Launcher process is upgraded and eliminates exception
Event.So the abnormality mark position of system exception event is emptied, and the state of spare Activity is changed to disable, again
Start Launcher process.
S40, in the absence of abnormality mark position, then start main Activity, and listen to Launcher be operating abnormally event
Specifically, if abnormality mark position is not present, illustrate that Launcher process is that anomalous event occurred, then start
Main Activity, and listen to Launcher and be operating abnormally event.
In Android system provided in this embodiment Launcher be operating abnormally restoration methods, starting Launcher into
Cheng Shi, judges whether there is the abnormality mark position of anomalous event, and then judges the state of spare Activity for available or disabling.
It can accurately judge currently to need to be started to be main Activity or spare Activity in this way, guarantee Launcher process
Normal operation.Meanwhile abnormality mark position there are when, judge that anomalous event is by the way that whether version number changes
It is no to be solved, realize fast and accurately starting Launcher process.
In yet another embodiment of the present invention, when starting Launcher process, a upgrading thread certainly can be created,
By whether disposing installation upgrade package from upgrading thread detection service device, if deployment installation upgrade package, downloads and installs liter
How grade packet, do not dispose installation upgrade package, then terminates from upgrading thread.This is because the upgrade package of server disposition can be for
Anomalous event is solved, is also possible to normally to upgrade.That is, starting Launcher process all detection service devices every time
Whether upgrade package is disposed, Launcher process can be run using real-time ensuring as latest edition.In practical applications, can also pass through
Upgrade package is detected and downloaded from upgrading thread, while being prompted for there are upgrade package, if needs to install and restarts Launcher
Process, and corresponding operating is carried out according to the user's choice.
