Abstract

The invention provides a terminal device pre-loaded application management method. When a terminal device is powered on for the first time, a link file is established in a user data partition, the link file is used for linking to a pre-loaded application installation package of a pre-loaded application list and preset in a system partition, and the pre-loaded application list is set in a way that the pre-loaded application list is not scanned when the terminal device is powered on. The identification is set to be a preset value, and therefore when the terminal device is powered on not for the first time, the link file established when the terminal device is powered on for the first time can be directly obtained. When the terminal device is upgraded, a newly increased pre-loaded application installation package exists in the upgrade version relative to the original version, the identification is reverted to be a default value, and therefore when the terminal device is powered on for the first time after being upgraded, a new link file used for linking to the newly increased pre-loaded application installation package is established in the user data partition. According to the invention, the case that the link needs to be established repeatedly when the terminal device is powered on each time can be avoided, at the same time, the fact that when a newly increased pre-loaded application exists in the upgrade version, the newly increased pre-loaded application can be used normally can be guaranteed.

Description

A management method for pre-installed applications on terminal equipment and terminal equipment

technical field

The present invention relates to the field of application management, in particular to a management method for pre-installed applications in terminal equipment and terminal equipment.

Background technique

The applications of terminal equipment are divided into system applications and user applications. The significant difference between the two is that the former cannot be uninstalled while the latter can be uninstalled. The reason is that system applications are installed in the read-only system partition, and users do not have permission to uninstall them. The user application is installed in the user data partition with read and write permissions, and the user can uninstall it by himself. In fact, there is also a pre-installed application between the system application and the user application. The so-called pre-installed application is the application that is preset in the system version or the application that is upgraded to the terminal when the system is upgraded (such as QQ, WPS) , these applications are directly provided by the third party with the installation package to the mobile phone manufacturer, and the mobile phone manufacturer integrates it into the system version or the upgraded version. Strictly speaking, pre-installed apps belong to system apps, but they are different from system apps because users expect pre-installed apps to be uninstallable, while third parties want users to uninstall pre-installed apps and restore them to factory settings. . This problem arises. If the pre-installed application is placed under the system partition, the pre-installed application cannot be uninstalled; if it is placed under the user data partition, the pre-installed application will be completely lost after the user restores the factory settings.

In response to such problems, the usual practice in the industry is to copy the pre-installed application installation package preset under the system partition to the user data partition during the first boot process, and install it under the user data partition, so that when the user data is scanned The pre-installed application of the partition will have the user application attribute, so it can be uninstalled by the user. Moreover, since the installation package is also located in the system partition, after restoring the factory settings, the pre-installed applications can still be reinstalled. However, the problem with this method is that the copying process of the pre-installed application installation package takes up the boot time, resulting in a longer boot time. In addition, the same pre-installed application installation package occupies not only the resources of the system partition but also the resources of the user data partition, resulting in a waste of space resources. In response to this problem, the following improvements have been made: Preinstall the pre-installed application installation package in the system partition and set it to not be scanned during the startup scan, link the pre-installed application installation package to the user data partition, so that the startup scan can reach the user When the data partition is used, the pre-installed application installation package is actually scanned. However, due to the scanning in the user data partition, the pre-installed application has user application attributes, so it can be uninstalled. Since the installation package is located in the system partition, pre-installed applications can still be reinstalled after factory reset. This method has a short link establishment process and a fast link speed, which greatly saves boot time compared to copying the installation package. Moreover, the same pre-installed application installation package only occupies system partition resources, which will not cause waste of space resources.

However, there are still many problems in the above solution, for example, the terminal device has to repeatedly establish a link every time it is turned on, or it will prolong the startup time.

Contents of the invention

The present invention provides a management method for pre-installed applications on terminal equipment and the terminal equipment, so as to solve the problem of repeatedly establishing links every time the system is turned on.

In order to solve the above problems, the present invention discloses a management method for pre-installed applications in terminal equipment, which includes the following steps.

When the terminal device is turned on for the first time, a link file for linking to the pre-installed application installation package is established in the user data partition, the pre-installed application installation package is preset in the pre-installed application directory of the system partition, and the pre-installed application directory Set to not be scanned at startup.

The flag is set as a preset value, and the flag is a preset value used to enable the terminal device to directly obtain the link file created when the terminal device is powered on for the first time when it is not powered on for the first time.

When the terminal device is upgraded, if there is a newly added pre-installed application installation package in the upgraded version relative to the original version, the identification will be restored to the default value, and the identification is the default value used to enable the terminal device to be turned on for the first time after the upgrade. , creating a new link file in the user data partition for linking to the newly added pre-installed application installation package.

Preferably, when the terminal device is upgraded, if there is a new pre-installed application installation package in the upgraded version relative to the original version, restoring the identification to the default value includes: when the terminal device is upgraded, executing the preset in the upgrade package command, the preset command is a command set when there is a new pre-installed application installation package in the upgraded version compared with the original version, and restores the identifier to a default value.

Preferably, when the terminal device is upgraded, if there is a new pre-installed application installation package in the upgraded version relative to the original version, then restore the identification to the default value, and the default value is used to make the terminal device after the upgrade When starting up for the first time, after the user data partition establishes a new link file for linking to the newly added pre-installed application installation package, it also includes: when the terminal device is powered on for the first time after upgrading, judging whether the identification is the default value ; If the identification is the default value, then create a new link file for linking to the newly added preinstalled application installation package in the user data partition, and the newly added preinstalled application installation package is preset in the preinstalled application directory .

Preferably, if the identifier is a preset value, the link file created when the terminal device is turned on for the first time is directly acquired.

Preferably, there are at least two preinstalled application installation packages, and the link files correspond to the preinstalled application installation packages respectively.

The present invention also discloses a terminal device, which includes a link establishment unit, which is used to establish a link file in the user data partition for linking to a pre-installed application installation package when the terminal device is turned on for the first time, and the pre-installed application installation package The pre-installed application directory is preset in the system partition, and the pre-installed application directory is set not to be scanned when starting up.

The identification setting unit is configured to set the identification as a preset value, and the identification is a preset value used to enable the terminal device to directly obtain the link file created when the terminal device is turned on for the first time when it is not turned on for the first time.

The upgrade unit is used to restore the identification to the default value when the terminal device is upgraded, if the upgraded version has a new pre-installed application installation package compared with the original version, and the default value is used to make the terminal device after the upgrade When booting for the first time, a new link file for linking to the newly added pre-installed application installation package is created in the user data partition.

Preferably, the upgrade unit is also used to execute a preset command in the upgrade package when the terminal device is upgraded, and the preset command is set when there is a new pre-installed application installation package in the upgrade version compared to the original version. The above identifies the command to restore the default values.

Preferably, the terminal device further includes an identification judging unit, configured to determine whether the identification is a default value when the terminal device is powered on for the first time after being upgraded; the link establishment unit is also configured to determine whether the identification is a default value At this time, a new link file for linking to the newly added preinstalled application installation package is established in the user data partition, and the newly added preinstalled application installation package is preset in the preinstalled application directory.

Preferably, the link establishment unit is further configured to directly acquire the link file created when the terminal device is turned on for the first time when the flag is a preset value.

Preferably, there are at least two preinstalled application installation packages, and the link files correspond to the preinstalled application installation packages respectively.

Compared with the prior art, the present invention includes the following advantages:

In the present invention, when the terminal device is turned on for the first time, a link file is established in the user data partition, and the link file is used to link to the pre-installed application installation package. The pre-installed application installation package is preset in the pre-installed application directory of the system partition, and the pre-installed application The directory is set not to be scanned at startup. Then set the identification as a default value, which is used to enable the terminal device to directly obtain the link file established when the terminal device is powered on for the first time when it is not powered on for the first time. In this way, when the terminal device is not turned on for the first time, it does not need to re-establish the link file, but directly uses the already established link file. When the terminal device is upgraded, if there is a newly added pre-installed application installation package in the upgraded version relative to the original version, the identification will be restored to the default value, and the identification is the default value used to enable the terminal device to be turned on for the first time after the upgrade. , creating a new link file in the user data partition for linking to the newly added pre-installed application installation package. When there are new pre-installed applications in the upgraded version, if the logo is not restored to the default value, the terminal device will not create a new link file corresponding to the newly-added pre-installed applications in the user data partition, and the newly-added pre-installed applications will not work normally. Installation and use, so the present invention can avoid the need to repeatedly establish a link every time it is turned on, and can also ensure that the new pre-installed application can be used normally when there is a new pre-installed application in the upgraded version.

detailed description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to FIG. 1 , it shows a flow chart of a method for managing pre-installed applications on a terminal device according to an embodiment of the present invention. The method may specifically include the following steps:

Step 101, when the terminal device is turned on for the first time, a link file for linking to the pre-installed application installation package is created in the user data partition, the pre-installed application installation package is preset in the pre-installed application directory of the system partition, and the pre-installed application installation package is preset in the pre-installed application directory of the system partition. The installed application directory is set to not be scanned at startup. .

In the embodiment of the present invention, terminal equipment refers to electronic equipment installed with Windows, IOS, Android and other systems, such as smart phones, tablet computers, notebook computers, ultra-mobile personal computers (English: Ultra-mobile Personal Computer, referred to as UMPC), netbook, personal digital assistant (English: Personal Digital Assistant, referred to as PDA) and other terminal equipment.

The user data partition is also called the data partition, which contains the user's data and stores information such as the user's contacts, text messages, settings, and applications. The data partition has read and write attributes, and restoring the factory settings is equivalent to erasing the partition and restoring it to the state when the device was started for the first time. The system partition, also known as the system partition, contains important files of the operating system and has read-only attributes. Restoring factory settings will not cause data loss in the system partition. If the pre-installed application installation package is stored in the user data partition, the installation package will be lost after the factory settings are restored, which cannot meet the requirements for reinstalling the third-party pre-installed application. In the embodiment of the present invention, the link file is established when the first boot is started. If the factory settings are restored, even if the previously established link file is deleted, the link file will still be re-established when the first boot after the factory settings are restored, and the pre-installed application will be installed. The package is stored in the system partition and will not be lost with the factory reset. Moreover, compared with copying the installation package, establishing a link file is much faster, and hardly affects the booting speed of the system.

Create a new directory (such as system/pre_app) in the system partition in advance, which is called the pre-installed application directory. The pre-installed application directory is used to store the pre-installed application installation package provided by the third party. In the actual process, this step is pre-customized in the system software by the mobile phone manufacturer. Of course, the pre-installed application directory may also be a directory that already exists in the system partition.

For system applications, since they are stored in the application directory under the system partition, system applications will be automatically installed with system-level permissions after scanning the directory, so system applications cannot be uninstalled. In this embodiment, the pre-installed application directory is set not to be scanned when booting, so that the pre-installed application directory is different from the system application directory of the system partition, and the purpose is to distinguish the pre-installed application from the system application.

The link file in the embodiment of the present invention is similar to a shortcut in a computer, and refers to an identifier linked to an actual file, so its size is very small and hardly occupies space resources of the data partition. Create a service for generating link files in init.rc started by the bootloader, where init.rc is a configurable initialization file. Usually, terminal equipment manufacturers can configure init.rc by themselves, and follow the configuration statements in init.rc when starting up Execute the corresponding function. In this embodiment, the Linux link command link is executed. The link command will first determine whether the directory (such as data/app) used to store the link file exists, and if it does not exist, it will be created automatically. Then link the pre-installed application installation package to data/app. The linking process is to create a link file in data/app. The link file points to the address of the pre-installed application installation package. When scanning the link file, the actual scan is the pre-installed application. Installation package.

In practice, there are at least two pre-installed application installation packages. Preferably, the link files are in one-to-one correspondence with the pre-installed application installation packages, that is, one link file corresponds to one pre-installed application installation package. The Link command traverses all pre-installed application installation packages, and creates a link file for each pre-installed application installation package.

It should be noted that the link file may have the same name as the pre-installed application installation package, or a preset name, such as numbers 1, 2, etc., which is not limited in this embodiment of the present invention.

Taking the terminal device of the android system as an example, after the terminal device is turned on for the first time, it will start the Package Manager Service (package management service), Package Manager Service is used to scan the installation package of the application directory and automatically install the application with user-level permissions or system-level permissions according to the partition where the application directory is located. The so-called user-level permissions refer to the operational permissions that users can perform including uninstallation. The so-called system Level permission means that the user does not have permission to uninstall the application. Specifically, during scanning, corresponding attributes, such as read-only attributes or readable and writable attributes, will be set for the application according to the partition where the installation package is located.

For the installation package under the system partition, it will have a read-only attribute after scanning. In the embodiment of the present invention, the pre-installed application directory is set to not be scanned at startup, in order to prevent the pre-installed application in the pre-installed application directory from being set as read-only. . When scanning linked files, since the data partition is scanned, the readable and writable attribute will be set for the preinstalled application corresponding to the linked file. In this way, pre-installed applications can be uninstalled by users themselves.

Step 102: Set the identifier as a preset value, which is used to enable the terminal device to directly obtain the link file created when the terminal device is turned on for the first time when it is not turned on for the first time.

In order to create a link file only when the terminal device is turned on for the first time and avoid creating a link file every time it is turned on, the embodiment of the present invention sets an identifier in the data partition to distinguish whether the data partition already has a link corresponding to the pre-installed application installation package It should be noted that the first startup here refers to the first startup of the terminal device before use or the first startup after restoring factory settings. It is necessary to establish a link file when starting up for the first time, and then set the logo to the default value. If the flag is set to the default value, it means that the link file corresponding to the pre-installed application installation package already exists in the data partition, and the terminal device does not need to create a new link file when it is turned on next time, but directly obtains the link file created when the terminal device is turned on for the first time. link files to avoid duplication of link files.

It should be noted that, in this embodiment of the present invention, no flag can be set before the terminal device is turned on for the first time. It can be understood that the default value of the flag is: no flag exists, which means that no link file is established in the data partition at this time; After the link file is created, add the flag. It can be understood that the default value of the flag is: the existence of the flag means that the link file has been created in the data partition. The logo is stored in the data partition, so that the logo will be deleted after the factory settings are restored. Or set the logo before the terminal device is turned on for the first time. It can be understood that the default value of the logo is: there is a logo, which means that the data partition has not established a link file at this time; and deleting the logo after the link file is established can be understood as, The default value of the flag is: there is no flag, which means that the link file has been established in the data partition. The logo is stored in the data partition, so that after the factory settings are restored, the logo will be added again. The above schemes are all within the protection scope of the present invention.

Step 103, when the terminal device is upgraded, if there is a newly added pre-installed application installation package in the upgraded version compared with the original version, restore the identification to the default value, and the default value is used to make the terminal device first after the upgrade. When booting for the first time, a new link file for linking to the newly added pre-installed application installation package is established in the user data partition.

In the prior art, after the system is powered on for the first time and the link of the pre-installed application has been established, if the link is repeatedly established every subsequent boot, the booting time will inevitably be prolonged. If it is simply to enable the terminal device to directly obtain the established link when it is not turned on for the first time, although the problem of repeated connection establishment can also be solved, when the terminal device is upgraded, if there is a new pre-installed application in the upgraded version, However, if the link established at the first boot is still directly obtained at this time, the newly added pre-installed application will not be scanned, and thus cannot be used by the user.

This embodiment cleverly sets the logo to a preset value after the terminal device is turned on for the first time to create a link file, so that the link file can be directly obtained by judging the value of the logo as the preset value when the terminal device is turned on later, without having to repeatedly create a link file. At the same time, when the new pre-installed application is included in the upgraded version, the identification is restored to the default value, so that the upgraded terminal device can re-establish a new link file for linking to the newly-added pre-installed application installation package.

It should be noted that the upgraded version also has the same pre-installed application directory as the original version, in which a new pre-installed application installation package is preset. When the upgraded terminal device is turned on for the first time, because the logo is the default value, the link file needs to be re-established. At this time, it includes linking to the link file A of the original pre-installed application installation package and linking to the new pre-installed application installation package. Link file B of the package. In the actual process, when the link command is executed on the original pre-installed application installation package, it will be found that the corresponding link file already exists in data/app, and the link command will not be executed at this time to save time. When the link command is executed for the newly added preinstalled application installation package, it will be found that there is no corresponding link file in data/app, and the link command will continue to execute to create a new link file corresponding to the newly added preinstalled application installation package.

When the terminal device in the embodiment of the present invention is turned on for the first time, a link file is established in the user data partition. The link file is used to link to the pre-installed application installation package. The pre-installed application installation package is preset in the pre-installed application directory of the system partition. The application directory is set to not be scanned at startup. Then set the identification as a default value, which is used to enable the terminal device to directly obtain the link file established when the terminal device is powered on for the first time when it is not powered on for the first time. In this way, when the terminal device is not turned on for the first time, it does not need to repeatedly create a link file, but directly uses the already established link file. When the terminal device is upgraded, if there is a new pre-installed application installation package in the upgraded version compared with the original version, the logo will be restored to the default value. The partition creates a new link file for linking to the newly added pre-installed application installation package. When there are new pre-installed applications in the upgraded version, if the logo is not restored to the default value, the terminal device will not create a new link file corresponding to the newly-added pre-installed applications in the user data partition, and the newly-added pre-installed applications will not work normally. Installation and use, so the present invention can avoid the need to repeatedly establish a link every time it is turned on, and can also ensure that the new pre-installed application can be used normally when there is a new pre-installed application in the upgraded version.

Embodiment one:

Referring to FIG. 2 , it is a flowchart of a method for managing preinstalled applications on a terminal device according to another embodiment of the present invention.

Step 201. When the terminal device is turned on for the first time, a link file for linking to a pre-installed application installation package is created in the user data partition, and the pre-installed application installation package is preset in the pre-installed application directory of the system partition. The installed application directory is set to not be scanned at startup.

Wherein, before the terminal device is turned on for the first time, the identification is not set in the data partition, which can be understood as setting the identification as a default value.

Specifically, the statement to execute init.rc in this embodiment is as follows:

Service preload-sh/system/bin/sh/system/etc/init.preload.sh

Class main

User root

One shot

The above is used to define the service in inti.rc, its role is to execute the init.preload.sh script, the script content is as follows:

#ln preload apks

if [!-f "data/app/exist"];then

echo "preloading application..."

for FILE in ˋls /system/preload;do #ln–s/system/preload/$FILE/$FILE.apk/data/app/preload_$FILE.apk

ln –s /system/preload/$FILE/data/app/ preload_$FILE

done

sync

echo "completed!">/data/app/exist

chmod 777/data/app/exist

sync

the fi

First, it will judge whether the identifier (that is, the node /data/app/exist) exists. If it exists, the link command will not be executed. If it does not exist, the Linux command link will be executed to link the pre-installed application installation package to data/app.

Step 202, add an identifier to the data partition.

Adding an identifier in this embodiment can be understood as setting the identifier as a preset value.

Step 203, scan the link file of the data partition, and actually scan the pre-installed application installation package according to the link file.

During the boot process, the Package Manager Service will scan the application directories of the system partition and the data partition respectively, and set corresponding attributes for the application according to the partition where the application is located.

Step 204, install the pre-installed application with the user-level authority.

After scanning, install the application to the terminal device according to its corresponding properties.

Step 205, when the terminal device is not powered on for the first time, directly obtain the link file created when the terminal device is powered on for the first time.

When starting up, the init.preload.sh script in step 201 will still be executed. Since the logo has been added in step 202, when it is judged that there is a logo, the link command will not be executed.

Step 206, the terminal device restores factory settings.

Among them, restoring the factory settings will delete the data in the data partition, that is, link files and logos will be deleted.

Step 207, when the terminal device is turned on for the first time after restoring the factory settings, return to step 201.

In this way, even if the factory settings are restored, the pre-installed application installation package can still be reinstalled to the terminal device.

Embodiment two:

Referring to FIG. 3 , it is a flowchart of a method for managing pre-installed applications on a terminal device according to another embodiment of the present invention.

Step 301 , respectively making an original version of a differential resource package and an upgraded version of a differential resource package.

Among them, the original version of the differential resource package is to write the source code according to the requirements, compile the source code, generate the original version of the data file and all the files required for the upgrade, convert the data file into the img format to generate the data image file, and upgrade all All the required files are packaged and compressed to generate the original version of the differential resource package, in which the data file includes all the files for making the T card upgrade package, and the differential resource package includes files compiled with the same source code as the data file. The upgraded version of the differential resource package is based on the source code, and according to the upgrade requirements, the source code is modified and compiled to obtain the upgraded version of the differential resource package.

Step 302, using the upgraded version of the differential resource package and the original version of the differential resource package to generate a differential package.

In step 303, it is judged whether there is a new pre-installed application installation package in the upgraded version relative to the original version in the differential package, and if there is a new pre-installed application installation package, perform step 304; otherwise, do not do any processing.

Specifically, this step includes the following sub-steps:

303a. Parse the upgraded version b and the original version a included in the difference package.

303b. Traverse the pre-installed application installation packages in the pre-installed application directory of the system partition in the two versions, and use a comparison algorithm to find whether there is a new pre-installed application installation package in the upgraded version b relative to the original version a.

Step 304, setting a preset command in the script of the difference package, where the preset command is used to restore the flag to a default value.

The above steps are the process of making an upgrade package.

Step 305, when the terminal device is upgraded, execute the preset command in the upgrade package.

Based on the first embodiment, after the preset command is executed, the identifier is deleted.

Step 306 , when the terminal device is turned on for the first time after the upgrade is completed, it is judged whether the flag is the default value, and if it is the default value, execute step 307 , otherwise execute step 308 .

Step 307: Create a new link file for linking to the newly added pre-installed application installation package in the data partition according to the default value identified.

In this embodiment, if the upgraded version includes newly added pre-installed applications, the terminal device will delete the logo after the upgrade is completed, and will execute the link command because the logo cannot be detected when starting up.

For the subsequent process, refer to steps 202-207 of Embodiment 1.

Step 308, directly acquire the link file created at the first startup according to the default value marked as.

For the subsequent process, refer to steps 203-207 of Embodiment 1.

In the embodiment of the present invention, when the terminal device is upgraded, when the upgraded version has a new pre-installed application compared with the original version, a preset command for restoring the identifier to the default value is set in the upgrade package, so that the terminal device When starting up for the first time afterward, a new link file for linking to the newly added pre-installed application installation package will be created in the data partition according to the flag as the default value. When there are new pre-installed applications in the upgraded version, if the logo is not restored to the default value, the terminal device will not create a new link file corresponding to the newly-added pre-installed applications in the user data partition, and the newly-added pre-installed applications will not work normally. Installation and use, so the present invention can avoid the need to repeatedly establish a link every time it is turned on, and can also ensure that the new pre-installed application can be used normally when there is a new pre-installed application in the upgraded version.

For the aforementioned method embodiments, for the sake of simple description, they are expressed as a series of action combinations, but those skilled in the art should know that the present invention is not limited by the described action sequence, because according to the present invention, Certain steps may be performed in other orders or simultaneously.
