Description
Technical Field
The present invention relates to the field of application program management technologies, and in particular, to a method and an apparatus for dynamically loading an application program.
Background
To reduce the number of releases of system versions, multiple users of the same platform typically use the same system version, i.e., maintain the same set of code. But different users have different demands on the native application, one part of the users needs to deeply customize part of the native application, and another part of the users may not need to deeply customize the native application. Thus, native applications cannot be directly modified to meet user customization needs. At present, the customized application program in the terminal is started mainly by reading the configuration file to determine the mode of starting the application program. In the method, the starting of the customized application program is realized by using a native default application program loading path, and the Android system is taken as an example, wherein the application program loading path of the Android native system mainly comprises/system/priv-app,/system/app,/product/priv-app and/product/app.
Because different users have different application programs, if a plurality of customized application programs with different package names exist in the same default path, the application programs with different package names scanned by a PMS (package manager service) in the terminal starting process can be installed on the terminal. After entering the system, the terminal desktop can present application programs of different clients. The same level default path cannot have multiple customized applications of different package names at the same time. If a plurality of application programs with the same package name exist in the terminal, the PMS finally only selects one application program which accords with the installation. The PMS records application information according to the application package name during the scanning process. Therefore, if the version information of the application is the same, the system defaults to install one application program, and cannot control which application program is to be installed, so that the same-level default path is an application program without a plurality of same package names.
Disclosure of Invention
The technical problems to be solved by the invention are as follows: the application program dynamic loading method and device are provided, the fact that a plurality of application programs with the same package name exist at the same time in the terminal is achieved, and the requirement of users on deep customization of the original application programs is met conveniently.
In order to solve the technical problems, the invention adopts the following technical scheme:
a method for dynamically loading an application program, comprising:
when receiving the starting signal, acquiring a user number from a user configuration table;
scanning a first path corresponding to the user number;
and judging whether the first path has a customized application program package, if so, acquiring the customized application program package and installing the customized application program package, and if not, acquiring a native application program package from a default path and installing the native application program package.
In order to solve the technical problems, the invention adopts another technical scheme that:
an application dynamic loading device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, the processor implementing the following steps when executing the computer program:
when receiving the starting signal, acquiring a user number from a user configuration table;
scanning a first path corresponding to the user number;
and judging whether the first path has a customized application program package, if so, acquiring the customized application program package and installing the customized application program package, and if not, acquiring a native application program package from a default path and installing the native application program package.
The invention has the beneficial effects that: by storing the customized application program package and the original application program package under different paths, a plurality of application programs with the same package name can exist in the terminal at the same time, and the default path is scanned after the first path is scanned based on the user number preferentially, so that the installation of the customized application program package or the original application program package can be realized in a dynamic loading mode according to the requirements of the user, and the requirements of the user on deep customization of the original application program are met.

example 1
In the embodiment, an Android system is taken as an example to explain an application program dynamic loading method; for Android and hong-and-Monte systems, the difference is only that the packaging formats of the application programs are different; if the Android system application program uses an apk format, and the hong Monte system application program uses a hap format; however, the mechanism or the characteristics of the system for scanning the application programs according to different catalogues are the same, namely, the Android system and the hong Monte system can scan the application programs of the appointed catalogues; the scheme in the present embodiment can be applied.
Referring to fig. 1, a method for dynamically loading an application program includes:
s0, presetting a user configuration table, customizing an application program package and a native application program package;
in this embodiment, a new customres partition (user-customized resource partition) is created, and the rights are modified to read-only; referring to fig. 2, the system architecture adopted in the present example includes a basic system and user-customized resources, and the basic system and the user-customized resources may be separately released; the basic system comprises partitions such as system, product and vendor, and the system application program and the native application program package are mainly stored in the system and product partitions; the user customized resources comprise custom mres partitions (user customized resource partitions) which belong to user customized resources and are mainly used for storing the preset user configuration table, wherein the preset user configuration table is internally provided with configuration information related to users such as user names, user numbers and the like; from the security point of view, the user number needs to be stored in a safer partition, while the security of the read-only partition that opens dm-quality is highest, such as system partition, product partition, vendor partition, and include customres partition; although partial catalogues and files of the data partition have certain strategy management and control, a certain degree of dynamic setting of some configuration files is convenient, the data partition is a readable and writable partition, so that the risk of modification of a user configuration table (such as a user number) exists; meanwhile, from the aspect of product planning, the user configuration table belongs to the category related to user customization, the system, the product and other partitions mainly belong to the basic system category, the vendor partition mainly belongs to the chip manufacturer customization category, and the custom mres user customization resource partition provided by the embodiment is a partition newly added by the embodiment and belongs to the user customization category; thus, in this embodiment the user configuration table is stored in a custom res user-customized resource partition; and a basic system only corresponds to one custom res user customized resource partition; each custom res custom resource partition only contains a corresponding user configuration table; in this embodiment, the custom application package is preset in the basic system partition.
TABLE 1 abbreviation and key term definition table
Referring to fig. 3, S1, when receiving a start signal, acquiring a user number from a user configuration table; taking an Android system as an example, some key services, such as a Package Manager Service (PMS), are started in the startup process of the Android system; and then the PMS acquires the user configuration table from the customres partition in the starting process, and acquires the user number of the current terminal.
S2, scanning a first path corresponding to the user number; wherein the first path is a next stage path of the default path; taking an Android system as an example, an application program loading path of the Android native system mainly comprises/system/priv-app,/system/app,/product/priv-app and/product/app; wherein the/system/priv-app and/system/app paths mainly store applications that are Android native and not customized by the vendor or user, and the/product/priv-app and/product/app paths mainly store applications that are Android native and possibly customized by the vendor or user; if the Android native setting application program loading path is/product/priv-app/Settings, when the user needs to deeply customize the native system application program, the loading path of the application program needing to be customized is newly added; each user has a unique corresponding user number, such as the number of user A is 001, the number of user B is 002, the number of user C is 003, and so on; when the C user needs to deeply customize the native setting application program, the newly added loading path is/product/priv-app/003/Settings; when the deep customization of the native setting application is not needed, the directory is not generated, i.e. the path does not exist; at this time, the terminal may include setting applications (Settings) under two directories of product/priv-app/Settings and product/priv-app/003/Settings at the same time; similarly, if other users have depth customization requirements, a loading path is newly added according to the rule; however, in order to follow the google original design intention, in general, the user is customized to an application program under a product catalog, so the embodiment will be described by taking the product catalog as an example; if the user number is 003, the corresponding first path is: product/priv-app/003/Settings.
S3, judging whether the first path has a customized application program package, if so, acquiring the customized application program package and installing the customized application program package, and if not, acquiring a native application program package from a default path and installing the native application program package;
if the first path/product/priv-app/003 comprises a custom application package Settings application, acquiring and installing the custom application package under the path; otherwise, acquiring and installing the customized application package from a default path/product/priv-app/Settings;
after the application program is acquired, the PMS analyzes the scanned application program, analyzes an android management.xml file, and stores data information into a memory; before starting up to enter the system, the PMS installs the application program meeting the expectations.
In another alternative embodiment, the custom application package is preset in a custom resource partition; the native application package is preset in a basic system partition; i.e., the newly added custom resource partition (custom partition) specifically stores custom applications, such as/custom res/priv-app and/custom res/app; meanwhile, the/customre/priv-app and/customres/app directories need to be added to the PMS boot scan directory; i.e. after starting up, the catalog of the system default is loaded by priority and then loaded by the catalog of the system; the principle is the same as the above steps; however, this embodiment requires release of the base system together with the version of the custom resource, and cannot be released separately; because the customres partition integrates the system application, and the system application program needs to depend on the basic system, otherwise, the problem of application program operation failure caused by incompatibility of the basic system by the system application of the customres partition possibly occurs; after receiving the update request, acquiring an update customized application program package and an update original application program package at the same time; updating the native application in the base system partition with the update-custom application package; and updating the native application package in the basic system partition through the updated native application package.
