[0030] The following is a detailed description of the installation method and device of the application provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] Figure 2 This is one of the flow charts of the method for installing the application provided in the embodiment of the present application. Figure 2 Describe the installation method of the application provided in the embodiment of the present application. Figure 2 As shown, the method includes:

[0032] Step 201: Receive an installation instruction for a target application.

[0033] Optionally, the execution subject of the application installation method provided in the embodiment of the present application is an application installation device. The application installation device is a target electronic device. The application installation method provided in the embodiment of the present application is used to install the target application on the target electronic device.

[0034] The installation device of the application can be implemented in various forms. For example, the installation device of the application described in the embodiment of the present application may include mobile terminals such as mobile phones, smart phones, laptops, digital broadcast receivers, PDAs (personal digital assistants), PADs (tablet computers), PMPs (portable multimedia players), navigation devices, smart bracelets, smart hands, digital cameras, etc., and fixed terminals such as desktop computers, etc. Below, it is assumed that the installation device of the application is a mobile terminal. However, it will be understood by those skilled in the art that, in addition to components specifically for mobile purposes, the construction according to the embodiment of the present application can also be applied to fixed type terminals.

[0035] The target application is an application to be installed. The target application is specifically an application, which is not specifically limited in the embodiment of the present application.

[0036] Optionally, when a user needs to install a target application, an installation instruction may be input to an installation device of the target application for the target application.

[0037] Optionally, the installation instruction may be a touch input, voice input, gesture input or key input for the target application, or may be a first operation.

[0038] For example, the first operation input by the user may be: the user clicks on a target control on a target interface; the target control is used to trigger the installation device of the application to perform an operation of installing the target application. The target interface may be an interface of an application store type application for displaying information of the target application. The information of the target application may include attribute information such as the name, version number, and file size of the installation file of the target application.

[0039] Exemplarily, the gesture input may be any one of a single-click gesture, a sliding gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture, and a double-click gesture.

[0040] It is understood that the above-listed installation instructions are exemplary, that is, the present application embodiment includes but is not limited to the above-listed inputs. In actual implementation, the installation instructions may also include any other possible inputs, which may be determined according to actual use requirements, and the present application embodiment does not limit them.

[0041] Optionally, the installation instruction may also be an installation instruction initiated by an operating system of an installation device of the application.

[0042] Exemplarily, when the application's installation device is configured to automatically update the application when connected to a Wi-Fi network, the application's installation device may receive an update instruction (ie, an installation instruction) initiated by the operating system for a target application to install a new version of the target application.

[0043] The installation device of the application program may receive the above installation instruction.

[0044] Step 202: In response to the installation instruction, receive a first data stream sent by the server and create a first session.

[0045] The first data stream is a data stream corresponding to the installation file of the target application; the first session includes the permission to perform write operations on the target directory; and the target directory is located in the internal storage space of the target electronic device.

[0046] Optionally, after receiving the installation instruction, the installation device of the application program responds to the installation instruction. The response of the installation device of the application program to the installation instruction may include: receiving a first data stream sent by a server and creating a first session.

[0047] It should be noted that the embodiment of the present application does not specifically limit the order of receiving the first data stream sent by the server and creating the first session. That is, the step of receiving the first data stream sent by the server can be performed first, and then the step of creating the first session can be performed; the step of creating the first session can also be performed first, and then the step of receiving the first data stream sent by the server can be performed; the step of receiving the first data stream sent by the server and the step of creating the first session can also be performed in parallel.

[0048] Receiving the first data stream sent by the server may include:

[0049] Access the server based on the download address of the installation file of the target application by calling the API (Application Programming Interface) for network communication;

[0050] After successfully connecting to the server, the installation file of the target application is downloaded from the download address, and the first data stream output by the server is received.

[0051] The server may be a server in a CDN; the server stores installation files of the target application.

[0052] For the Android operating system, the installation file is an APK (Android application package) file; for the iOS operating system, the installation file is a file in ipa, pxl or deb format.

[0053] A first session including permission to perform write operations on the target directory may be created based on a session control mechanism (ie, Session mechanism) of the operating system.

[0054] Optionally, the first session may include multiple interfaces; at least one of the interfaces includes permission to perform write operations on the target directory, and the interface is used to perform write operations on the target directory.

[0055] Optionally, when the operating system of the target electronic device is an Android system, the target directory may be a data directory.

[0056] Optionally, when the operating system of the target electronic device is iOS, the target directory may be the Applications directory.

[0057] Step 203: According to the first session, write the first data stream into the target directory.

[0058] Optionally, according to the permission for performing a write operation on the target directory included in the first session, an operation of writing the first data stream is performed on the target directory through the first session.

[0059] Step 204: When all installation files of the target application are written into the target directory, install the target application.

[0060] Optionally, when it is determined that all installation files of the target application are written into the target directory, that is, all data streams corresponding to the target application are stored in the target directory, the target application is installed.

[0061] Optionally, in an Android system, the target application program may be parsed and installed according to all stored first data streams by calling an installation method in PackageManager (which may be used to install and uninstall APP).

[0062] Optionally, the target application can also be installed by calling the installation method of the system API. APIs can be some predefined functions that provide applications and developers with the ability to access a set of routines based on certain software or hardware. The API in the embodiment of the present application can install the target application by calling a specific installation service. For example, for the Android system, the target application can be installed by calling the Install Package Process installation service.

[0063] Figure 3 The following figure shows the installation process of the application provided in the embodiment of the present application. Figure 3 and Figure 1 It can be seen that in the embodiment of the present application, the installation file of the application is directly written to the internal storage space of the electronic device, which reduces the steps of reading and writing the external storage space of the electronic device and copying the installation file from the external storage space to the internal storage space.

[0064] The embodiment of the present application receives the first data stream sent by the server in response to the installation instruction, and creates a first session. According to the first session including the permission to perform write operations on the target directory, the first data stream is written into the target directory in the internal storage space of the electronic device. In the process of installing the application, only the internal storage space needs 1 times the storage space of the installation file size, which can reduce the storage space used, realize one-stop lossless space streaming installation, improve the overall success rate of download and installation, and only perform a download operation once without having to perform a local copy operation, which can simplify the process, improve the overall speed from receiving the installation instruction to the completion of the installation, and reduce the total time consumed for download and installation. Furthermore, download and installation can be realized without the need for read and write permissions of the external storage space, which can avoid the phenomenon of installation failure due to the lack of read and write permissions of the external storage space, and the phenomenon of poor user experience caused by prompting the user to authorize due to the lack of read and write permissions of the external storage space.

[0065] Optionally, receiving a first data stream sent by a server includes: receiving the first data stream and storing the first data stream in a buffer register.

[0066] Optionally, after receiving the first data stream, a buffer register (buffer) may be used to store the received first data stream.

[0067] It can be understood that the buffer register in the embodiment of the present application is an input buffer for temporarily storing the first data stream. The first data stream stored in the buffer register is waiting to be written into the target directory.

[0068] The embodiment of the present application can separate the operation of receiving the first data stream from the operation of writing the first data stream to the target directory by storing the received first data stream in a buffer register, thereby avoiding mutual influence between the above two operations, thereby increasing the speed of downloading the installation file of the target application from the server and the speed of writing the installation file of the target application to the target directory, and reducing the total time consumed in downloading and installation.

[0069] Optionally, writing the first data stream to the target directory according to the first session includes: writing the data in the buffer register to the target directory according to the first session at a first time interval.

[0070] Optionally, downloading the installation file of the target application requires a certain amount of time, and downloading and writing can be achieved based on the buffer register, that is, after the first data stream is stored in the buffer register, at every first time interval, according to the first session, the data in the buffer register is cyclically read and the read data is written to the target directory.

[0071] It is understandable that after the data in the buffer register is read, the buffer register is empty and can store new data.

[0072] The first time interval may be pre-set according to actual conditions. The specific value of the first time interval is not specifically limited in the embodiment of the present application.

[0073] Optionally, when the installation file of the target application is a compressed file (for example, compressed using GZIP), and when the first data stream written to the target directory meets the decompression conditions, the partial data that meets the decompression conditions can be decompressed first without having to wait until all the installation files of the target application are written to the target directory before decompressing them. This allows downloading, writing, and decompression to be achieved, further reducing the total time spent on downloading and installation and improving user experience.

[0074] The embodiment of the present application writes the data in the buffer register to the target directory at a first time interval and according to the first session, thereby separating the operation of receiving the first data stream from the operation of writing the first data stream to the target directory, avoiding mutual influence between the above two operations, thereby increasing the speed of downloading the installation file of the target application from the server and the speed of writing the installation file of the target application to the target directory, and reducing the total time consumed in downloading and installation.

[0075] Optionally, creating the first session includes: creating the first session based on the first application.

[0076] The first application is a target type application.

[0077] Optionally, the first session may be created based on an application of a target type. The type of the first application is the target type.

[0078] Optionally, the target type of application may be an application that comes with the operating system of the application installation device and is used to install the application.

[0079] Optionally, the first application may be any application of the target type.

[0080] Exemplarily, when the operating system of the application installation device is an Android system, the first application may be an installation manager PackageInstaller.

[0081] PackageInstaller is the default application of the Android system, which is used to interactively install ordinary package files. PackageInstaller can provide a user interface to manage applications (APP) or package files (APK).

[0082] The embodiment of the present application creates a first session through an application of the target type, without calling other applications to create sessions, thereby reducing resource overhead.

[0083] In order to facilitate the understanding of the above embodiments of the present application, the installation process of the application is described below through an embodiment. In the embodiment of the present application, the operating system of the target electronic device is described as an Android system as an example.

[0084] like Figure 4 As shown, after receiving the installation instruction, the installation process of the target application may include the following steps:

[0085] Step 401: Based on the address of the APK, obtain the network IO stream.

[0086] The address of the APK of the target application is requested through the API for network communication. After the network connection is successful, the IO stream corresponding to the APK (referred to as "network IO stream") can be obtained based on the communication network. The network IO stream is the first data stream.

[0087] Step 402: Create a first session and open a file channel in the data directory.

[0088] Create a Session (i.e., the first session) through the CreateSession interface; create a SessionId (i.e., the id of the first session) based on the SessionID interface of the first session; open the file channel of the data directory based on the SessionId and the OpenWrite interface of the first session. The Android system returns the session object of the first session. Based on the OutputStream of the file channel, the upper-layer application can write files to the system directory (including the data directory). For the first session, the network IO stream is InputStream.

[0089] It should be noted that step 401 may be performed first and then step 402, or step 402 may be performed first and then step 401, or step 401 and step 402 may be performed simultaneously.

[0090] Step 403: connect the network IO stream and the first session IO stream, and write the read buffer of the network IO stream into the data directory through the first session.

[0091] Read the buffer of the network IO stream and write the read buffer to the data directory through the first session. This process is to read the buffer of the network IO stream in a loop to achieve reading and writing at the same time. Write the read buffer to the data directory through the first session, which is achieved through the fsync interface of the first session.

[0092] Step 404: After the network IO stream is read, the commit interface of the first session is executed.

[0093] After the network IO stream is read, the first session also completes writing the APK to the data directory, and the commit interface of the first session is executed, triggering the Android system to execute the APK parsing step and install the target application.

[0094] It should be noted that the execution subject of the application installation method provided in the embodiment of the present application may be the application installation device, or the control module in the application installation device for executing the application installation method. In the embodiment of the present application, the application installation device provided in the embodiment of the present application is described by taking the application installation method executed by the application installation device as an example.
