Detailed Description
Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, the inventive principle of the present invention is described:
at present, application programs in a terminal device adopting an Android operating system are divided into preset applications (also called system applications) and user applications. The preset application is the application preset when the terminal equipment leaves the factory, and is characterized in that: the application program is stored under an application installation directory, typically referred to as/system/app directory, of the system partition with read-only properties. And the library file corresponding to the application program is stored in the system partition/system/lib directory and cannot be deleted. The user application, namely the application which is independently installed by the user, is characterized in that: when the corresponding library file is installed, the corresponding library file is automatically stored in a user directory corresponding to an application program under a data/app-lib directory in the user partition and can be automatically unloaded. The library files of each preset application of the terminal equipment are stored in the system partition/system/lib directory, so that when a plurality of application programs adopt library files with the same name, the library files conflict, only one of the library files can be ensured, and if the functions realized by the library files are different, the problem of abnormal function or running exit of one application can be caused.
Based on the above situation, the inventor of the present invention considers that the library file is generally loaded by a universal interface method system. The system, the loadlibrary, in the actual execution process, loads the library file in a way of searching the library file name, and the searching process specifically includes: firstly, searching a library file corresponding to an application program under a library file directory (usually/system/lib) in a system partition, and if the library file is searched, loading the library file; and if the corresponding library file is not found under the library file directory in the system partition, finding the corresponding library file under the user directory corresponding to the application program under the library file directory in the user partition, and loading the library file. Further, in the embodiment of the present invention, by saving the library file of the preset application program in the user directory corresponding to the application program in the user partition, a situation that the library files of the preset application program are all mixed in the library file directory in the system partition in the prior art is avoided, and further, a problem that library file collision may occur when the library file renaming of the application program occurs is avoided. In addition, in the embodiment of the present invention, after the ROM of the operating system is written into the terminal device and the operating system is started, the library file is stored in the corresponding directory of the user partition, so that the step of separately decompressing the APK file, taking out the library file from the APK file, and placing the library file in the system/lib directory of the SDK (Software Development Kit) of the project engineering is omitted when the preset application program is integrated into the ROM, thereby simplifying the integration step of the APK library file.
The first embodiment is as follows:
based on the above inventive principle, the present invention provides an installation method of an application program, as shown in fig. 1, the method includes:
s101, obtaining an APK file of an application program in a system partition. Wherein, the APK file comprises the library file of the application program.
Specifically, when a Read Only Memory (ROM) version of the terminal device is manufactured, the APK file may be integrated in the ROM version, so that after the ROM version is written into the terminal device, the APK file is stored in a corresponding directory in a system partition with Read Only permission, thereby presetting the application program in the terminal device.
And S102, storing the library file of the application program into a user directory corresponding to the application program in the user partition. So that the library files of the application under the user directory can be loaded through the common interface when the application is running.
For example, in the user partition, the library file of the application program is usually stored in the storage directory corresponding to the application program under the/data/app-lib directory. For example, the library file of the application program A is saved under the data/app-lib/A, and the library file of the application program B is saved under the data/app-lib/B. And then the library files of the application programs preset in the system partition are stored in the user directory corresponding to the application programs in the user partition, so that the condition that the library files conflict due to the same name of the library files of a plurality of application programs is avoided.
In addition, in the prior art, when an application is preset as a system application, an APK (android package) file needs to be placed at a corresponding position under a/system directory, and a library file of the application needs to be placed under the/system/lib directory separately. Specifically, the general steps of presetting the application program include the following: firstly, manually decompressing an APK file of an application program, and taking out a library file contained in a lib directory in the APK file; secondly, placing the APK file under a system/app or/system/priv _ app directory of a project engineering SDK (Software Development Kit); thirdly, placing the taken library file in a system/lib directory of the project engineering SDK; fourthly, compiling and packaging are carried out through the project engineering compiling command, and a ROM version is generated. As can be seen, in the prior art, in order to place a library file into a system/lib directory in a system partition, an APK file needs to be manually decompressed, and the library file is taken out and placed into the system/lib directory of an SDK. Not only does this increase the workload of the developer, but also the manual process is prone to error, which may result in the library file of the APK being missed. In the invention, the library file is stored in the user directory corresponding to the application program in the user partition, so that the library file can be correspondingly installed through the package management service program packagemanagerServer after the android system is started, and the process of manually placing the library file is avoided. When the ROM version is generated by compiling, the method of the invention only needs to place the APK file of the application program in the corresponding directory of the project engineering SDK and then compile to generate the ROM version, thereby saving the process of presetting and installing the library file of the application program and reducing the development cost.
Example two:
based on the installation method of the application program provided in the first embodiment, in an implementation manner, the APK file is stored in an application installation directory in the system partition. Specifically, the application installation directory in the system partition is usually/system/app or/system/priv _ app. That is, when the ROM version is generated, the APK file is placed under the/system/app or/system/priv _ app directory of the project engineering SDK. Furthermore, as shown in fig. 2, the method for installing an application program provided by the present invention specifically includes:
s201, scanning an application installation directory in a system partition by using a PackageManagerServer package management service program to obtain an APK file.
After the Android system is started, the SystemServer starts an Android package management service program PackageManagerServer. After the PackageManagerServer is initialized, scanning all APK files in a/system/app directory, and further acquiring the APK files of the application program.
S202, determining application program information according to the APK file.
Specifically, the packagemanargerserver calls a packagemerer to analyze a configuration file android document.
S203, after determining that the application information does not exist in the package management service program, storing the application information in the package management service program.
Specifically, after determining that the application information does not exist in the PackageManagerServer, the application information is saved to the PackageManagerServer by calling the packagemarser.
And S204, after determining that the application program information does not exist in the package management service program, saving the library file of the application program to a user directory corresponding to the application program in the user partition.
Specifically, when the information of the application program does not exist in the PackageManagerServer, the fact that the application program is not installed in the terminal device is indicated, and further, the application program and the library file are installed in a mode that the information of the application program is stored in a package management service program and the library file is stored in a corresponding user directory in a user partition.
In the embodiment of the invention, the APK file is stored in the application installation directory in the system partition, and the PackageManagerServer is used for realizing the installation of the library file in the installation process of the application program, so that the application program and the library file are automatically installed when the terminal equipment judges that the application program is not installed currently after starting up.
In an implementation manner, considering that the library file of the application program is saved in the readable and writable user partition in the embodiment of the present invention, and in order to avoid a problem that the library file is deleted due to a user misoperation or the like, after determining that the application program information exists in the package management service program, the method provided in the embodiment of the present invention further includes:
s205, judging whether a user directory corresponding to the application program exists in the user partition or not and whether a library file of the application program is stored in the user directory or not.
Specifically, the PackageManagerServer judges whether a user directory of the current application program exists under the data directory.
S206, after determining that the user directory corresponding to the application program does not exist in the user partition, establishing the user directory of the application program, and storing the library file of the application program into the user directory corresponding to the application program in the user partition.
Specifically, when the PackageManagerServer judges that the data directory does not have the user directory of the application program, the user directory is created, so that the library file of the application program is stored in the user directory corresponding to the application program in the user partition.
For another example, when the PackageManagerServer reads the package name of the APK file of the application program and judges that no directory named by the package name exists under the/data/app-lib directory, the directory/data/app-lib/AAA is created, and the library file is copied to the/data/app-lib/AAA directory.
And S207, after the user directory corresponding to the application program exists in the user partition and the user directory does not have the library file of the application program, saving the library file of the application program to the user directory corresponding to the application program in the user partition.
For example, when the PackageManagerServer reads the package name of the APK file of the application program, and judges that a directory named by the package name exists under the/data/app-lib directory, but no library file exists under the directory, the library file is copied to the/data/app-lib/AAA directory.
Additionally, in one implementation, it is contemplated that the application may be updated during use of the terminal device. Therefore, after determining that the application information exists in the package management service program, the installation method provided by the invention further comprises the following steps: and reading the application program information stored in the package management service program by the packageParser, comparing the application program information with the current application program information, and updating the current application program information to the package management service program if the application program information is inconsistent with the current application program information.
The following describes, with reference to an example, specific implementation steps of the application installation method provided by the second embodiment of the present invention:
firstly, before installing the application program, when the ROM version of the terminal device is generated, the APK file of the application program is placed under the/system/app directory of the project engineering SDK and then compiled into the ROM version of the terminal device.
Then, the Android package management service program packagemanagerServer realizes the installation of the application program, wherein the installation of the library file is included, and the method specifically comprises the following steps:
s301, starting an Android system, and starting an Android package management service program packagemanagerServer by the SystemServer.
S302, completing initialization of the PackageManagerServer, and scanning all APK files in the/system/app directory.
S303, calling a PackageManagerServer to analyze a configuration file AndrodiMenifest.xml in the APK file, judging whether the current PackageManagerServer has the application program information, and if not, executing the step S305; if yes, go to step S304.
S304, reading the existing version information of the application program, comparing the version information with the current application program information, and executing the step S305 if the version information of the application program is inconsistent with the current application program information; if yes, go to step S306.
S305, updating or saving the application program information to a packagemanagerServer by the packagemarer.
S306, judging whether the data directory has a user directory of the current APK or not by the packagemanagerServer, and if not, creating and executing the next step; if so, the next step is directly executed.
S307, calling a packagemerarser to analyze the APK file, judging whether a so-base file exists or not, and if so, executing the next step; if not, the process is finished.
S308, reading the current APK package name by the PackageManagerServer, judging whether a directory named by the package name exists under the data/app-lib, and if not, creating and executing the next step; if yes, the next step is executed.
S309, the packagemanagerServer judges whether a corresponding library file exists in the data/app-lib directory, and if not, the next step is carried out; if yes, the process is ended.
S310, the PackageManagerServer copies the so-library file to the corresponding data/app-lib directory.
In the embodiment of the invention, the library files of the preset application program are stored in the user directory corresponding to the application program in the user partition, so that the condition that the library files of the preset application program are all mixed in the library file directory in the system partition in the prior art is avoided, and the problem of library file collision possibly occurring when the library files of the application program are renamed is further avoided. In addition, in the embodiment of the present invention, after the ROM of the operating system is written into the terminal device and the operating system is started, the library file is stored in the corresponding directory of the user partition, so that the step of separately decompressing the APK file, taking out the library file from the APK file, and placing the library file in the system/lib directory of the SDK (Software Development Kit) of the project engineering is omitted when the preset application program is integrated into the ROM, thereby simplifying the integration step of the APK library file.
Example three:
based on the installation method of the application provided in the first embodiment, it is considered that in the installation method of the application provided in the second embodiment, the existing package installation mechanism of the Android needs to be modified, that is, the PackageManagerServer is improved. In practical application, however, modification of the existing installation mechanism of the Android, that is, modification of the Android system, may not be wanted. Furthermore, an embodiment of the present invention further provides another installation method of an application program, where an APK file of the application program is stored in a private directory in a system partition. Specifically, as shown in fig. 3, the method includes:
s402, scanning a private directory in the system partition by using a preset service program, and acquiring an APK file of the application program.
For example, a private directory, thirdapp, is created in the system partition, which holds all the preset third party applications, including the above-mentioned application.
And S403, calling a system installation interface by using a preset service program and installing the APK file into the user partition.
Wherein installing the APK file into the user partition comprises: and acquiring the library file of the application program contained in the APK file, and storing the library file of the application program into a user directory corresponding to the application program in the user partition.
Specifically, in the present invention, a preset service program is implemented, and specifically, the preset service program may be an Android service program apk (installthidapp). And then, the APK files under the private directory in the system partition are installed in the user partition through the preset service program, and then the library files of the application program are automatically placed under the directory corresponding to the application program of the data partition, so that the manual operation process is removed, meanwhile, the corresponding library files can also be placed at different positions because different application programs correspond to different user directories, and the problem of conflict caused by duplicate names of the library files is effectively solved.
In one implementation manner, in order to automatically install the application program stored in the private directory in the system partition at the time of system startup to achieve the above effect, the installation method provided in the embodiment of the present invention further includes, before performing the above steps S402 and S403:
s401, starting of the android operating system is detected, and after the android operating system is determined to be started successfully, a preset service program is operated. The preset service program scans the private directory in the system partition, acquires the APK file of the application program, and calls the system installation interface and installs the APK file into the user partition.
The following describes, with reference to an example, specific implementation steps of the application installation method provided by the second embodiment of the present invention:
first, when a ROM version of the terminal device is generated, a private directory thirdapp is created in the system partition, which holds all third party APK programs.
And then, realizing an Android service program APK (Android Thidap), wherein the APK automatically runs after the Android system is successfully started, scans/system/third directory, and installs the application programs in the directory one by one. The method specifically comprises the following steps:
and S1, monitoring a message that the system is successfully started, and carrying out the next step if the system is successfully started.
S2, traversing files in the system/thirdapp directory, judging whether the files are APK files or not, and if the files exist, then carrying out the next step; if not, the process is finished.
S3, analyzing the APK file, judging whether the APK is installed in the current system, if so, returning to S2 and traversing the next APK file; if not, the next step is carried out.
And S4, calling a system installation interface to install the APK, and in the system installation process, copying the so library file to the corresponding app-lib directory.
By the method for installing the application program, provided by the embodiment of the invention, all library files of the application program can be automatically placed under the directory corresponding to the application program in the data partition when the system is started, and the manual operation process is eliminated. Meanwhile, different application programs correspond to different user partition directories, and corresponding library files can be placed at different positions, so that the problem of conflict caused by duplicate names of the library files is effectively solved.
