Android (Android) system is a free and open source operating system based on Linux, mainly used in mobile devices, such as smart phones, tablet computers, TVs, set-top boxes, game devices, etc. Mobile phones using the Android operating system have a considerable share in the market.

Since the development and release of Android system software is often not a one-time process, the Android system needs to be continuously updated and upgraded according to the requirements of actual applications. Therefore, there will be multiple system software upgrades in the life cycle of devices using the Android system. . Usually, the Android system establishes a connection with the service for providing the Android system upgrade through the network (including WIFI and 3G) to download the upgrade package and complete the upgrade process.

However, this upgrade process requires the Android system to start normally, and to establish a smooth connection with the Google server that provides upgrade services for the Android system. It cannot be dealt with when the Android system cannot be started normally. There are certain problems. In some cases, the common method is to manually add an upgrade package to the device and perform local upgrade in recovery mode. However, this upgrade method consumes a lot of manpower and material resources for the upgrade of batch devices (such as set-top boxes), which is inconvenient to implement.

In order to solve the above problems, the present application provides a new Android system upgrade method. Please refer to FIG. 1 . An embodiment of the Android system upgrade method provided by the present application includes steps 101 to 106 .

101. Determine whether an upgrade instruction instruction exists in the first storage space.

Specifically, this solution is applied to a device equipped with an Android system, and the specific device type may be a smart phone, a tablet computer, a TV, a set-top box, a game device, etc., which is not specifically limited here. Determine whether there is an upgrade instruction instruction in the first storage space, wherein the first storage space can be a specific area in the memory, for example, the upgrade instruction instruction can be stored in the MISC partition, and the MISC partition can be used to store parts related to system upgrades This information is used in recovery mode (recovery mode). When the device is in bootloader mode (Bootloader mode), the data in the partition will be read to determine whether the system enters recovery mode or the main mode of Android system. The settings of the controls can be determined according to the actual needs, which are not limited here.

The upgrade instruction instruction is used to indicate whether the system enters the upgrade. The specific upgrade instruction instruction may also include information such as the server address pointed to by the upgrade, the file transfer protocol used, and the downloaded file storage address, etc., which are not limited here. The upgrade instruction instruction can be pre-edited in the first storage space by the staff, and the use of the upgrade instruction instruction can be activated when the Android system is running normally, so that the upgrade can be performed when the system is restarted, or the user can activate the upgrade by triggering a specific button in the boot loading mode. Indicates an instruction to perform the subsequent upgrade process, which is not limited here.

102. Enter the recovery mode.

Specifically, if there is an upgrade instruction instruction in the first storage space, the system enters a recovery mode (recovery mode). The recovery mode is the backup function of the Android system, which refers to a method that can modify the data or system inside the Android system. mode (similar to windows PE or DOS). In this mode, the existing system can be backed up or upgraded, and the factory settings can also be restored here. Perform subsequent procedures in recovery mode to complete the upgrade process.

103. Acquire the target IP address according to the upgrade instruction.

Specifically, the target IP address is acquired according to the upgrade instruction instruction. The target IP address is the IP address applied for by the system used for the upgrade. Specifically, the acquisition method of the target IP address can be based on Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configuration Protocol), Ethernet-based point-to-point communication Protocol (PPPOE, Point-to-Point Protocol Over Ethernet) or any method based on static IP. The specific acquisition method can be pre-written with the upgrade instruction instruction, and the target that can be used for data transmission with the outside world can be obtained through the corresponding process. The IP address will not be repeated here.

104. Establish a data connection with the target server based on the target IP address.

Specifically, a data connection with the target server is established based on the target IP address. The target server is the server used to provide the upgrade data package, and the target server can be set by the operator. Since it supports a specific upgrade of the Android system, it is used to deal with some special situations, which is not limited here. The network address of the target server may also be pre-written with an upgrade instruction, which is not specifically limited here. In the process of establishing a data connection with the target server based on the target IP address, the corresponding Domain Name System (DNS, Domain Name System) information can also be set based on the target IP address, and a distributed system that maps domain names and IP addresses to each other, so that The network access process went smoothly.

105. Receive an upgrade data packet sent by the target server.

Specifically, after the data connection is established between the target server and the Android system to be upgraded, the upgrade data package sent by the target server is received, wherein the data of the upgrade data package is determined according to the system version of the current Android system. Before the upgrade data package sent by the target server, the target server and the Android system can also communicate to determine the required upgrade data package version, so that the upgrade process can be carried out smoothly, which can be determined according to the actual situation, which is not limited here. The upgrade data package can be stored in a specific upgrade package storage path in the Android system to support the smooth progress of the upgrade process.

106. Complete the Android system upgrade process based on the upgrade data package in the recovery mode.

Specifically, after receiving the upgrade data package, the system completes the upgrade process of the Android system based on the upgrade data package in the recovery mode. For the specific upgrade process, reference may be made to the upgrade process in the Android system recovery mode in the prior art, which will not be repeated here.

It can be seen from the above technical solutions that the embodiments of the present application have the following advantages: the present application provides an Android system upgrade method, comprising: determining whether an upgrade instruction instruction exists in the first storage space; if there is an upgrade instruction in the first storage space; the upgrade instruction instruction, then enter the recovery mode; obtain the target IP address according to the upgrade instruction instruction; establish a data connection with the target server based on the target IP address; receive the upgrade data packet sent by the target server; The upgrade process is completed based on the upgrade data package in the recovery mode. Based on the upgrade method provided by this application, the device can download the data package used for the upgrade in the recovery mode where the Android system is not started normally, and complete the upgrade process of the Android system in the recovery mode, so that the device can be used in the recovery mode when the Android system fails to work normally. In the case of startup, the upgrade process is successfully completed, which ensures the practicability of the Android system upgrade process.

In order to facilitate the use of this method in the actual upgrade process, the present application also provides a more detailed embodiment that can be selectively implemented. Please refer to FIG. 2. An embodiment of the Android system upgrade method provided by the present application includes the following steps: 201-step 209.

201. In the boot loading mode, determine whether an upgrade instruction instruction exists in the first storage space.

Specifically, it is determined whether there is an upgrade instruction instruction in the first storage space in a boot loader mode, wherein the boot loader mode is used to initialize to access random access memory to access non-volatile devices or to operate A program that loads system programs and data into random access memory. That is, the mode that the device is initially in when it is powered on. In this mode, it is determined whether there is an upgrade instruction instruction in the first storage space. In order to support the execution of this process, the first storage space can be set to be related to the boot loading mode. The storage location, for example, the first storage space can be the BCB data (Bootloader Control Block) under the MISC partition. When the bootloader mode starts, the corresponding data in this partition will be read to determine whether the system enters the Android main system mode or recovery mode. For the specific form of the upgrade instruction instruction, please refer to FIG. 3, which is an example of some fields representing the upgrade instruction instruction in the BCB data. It can be understood that in the actual implementation process, each field of the upgrade instruction instruction can be adjusted to Make the upgrade instruction instruction field play a corresponding role and instruct the system to upgrade, which is not specifically limited here. The upgrade instruction instruction can be modified by an instruction sent by the server when the system is connected to the Internet, or can be modified manually by the user through a specific button, which can be determined according to the actual situation, and is not limited here. If there is no upgrade instruction instruction in the first storage space, step 202 is executed to determine whether the user inputs a preset instruction. If there is an upgrade instruction instruction in the first storage space, step 203 is executed to enter the recovery mode.

202. Determine whether the user inputs a preset instruction.

Specifically, it is determined whether the user has input a preset command, wherein the preset command is used to instruct the system to upgrade. For the situation where the system cannot establish a normal connection with the server due to other special circumstances such as system upgrade, the system cannot obtain it through the network. Upgrade instruction instruction, so it is necessary to set the method of manually triggering the upgrade instruction instruction, that is, the preset instruction. When the user enters the preset instruction (such as button: 2486), the corresponding data in the first storage space can be triggered to change and activate. The upgrade instruction instruction is used to complete the upgrade when the system cannot be started normally or a connection cannot be established with the server after the system is started. Specifically, the activation rule of the upgrade instruction instruction can be pre-written in the first storage space and its corresponding document. There is no specific limitation here. If the user does not enter an upgrade instruction in the bootloader mode, it means that no upgrade is required, and the device enters the Android main system. If the user enters the preset operation, it means that the device needs to be upgraded, activate the upgrade instruction pre-written in the first storage space, and re-execute step 201 to identify the activated upgrade instruction, and then proceed to step 203, the system enters The recovery mode, specifically, after the user inputs a preset operation, the device can be restarted so as to re-read the upgrade instruction instruction, thereby supporting the progress of the upgrade process, which can be determined according to the actual situation, and is not limited here.

203. Enter recovery mode.

Specifically, the system enters the recovery mode so as to perform subsequent upgrade steps. This step is similar to step 102 in the aforementioned embodiment corresponding to FIG. 1 , and will not be repeated here.

204. Acquire the target IP address according to the upgrade instruction instruction.

Specifically, the target IP address is obtained based on a first preset protocol, and the first preset protocol includes: any one of a dynamic host configuration protocol, an Ethernet-based point-to-point communication protocol, or a static IP, wherein the dynamic host configuration Protocol (DHCP, Dynamic Host Configuration Protocol) is a LAN network protocol. Its main function is to centrally manage and assign IP addresses. It enables network devices in the current LAN environment to obtain IP addresses, Gateway addresses, DNS server addresses and other information. Normal network communication. Point-to-Point Protocol Over Ethernet (PPPoE) is a network tunneling protocol that encapsulates the point-to-point protocol in an Ethernet frame. Because the point-to-point protocol is integrated in the protocol, the functions of authentication, encryption and compression that cannot be provided by traditional Ethernet can be realized, and it can also be used in the protocol system such as cable modem and digital subscriber line that provide access services to users with the Ethernet protocol. Specifically, this solution is described by using DHCP as an example. It is worth noting that in the actual implementation process, this solution can also obtain an IP address in any other manner, which is not limited here.

In this solution, a simplified version of the DHCP client function is implemented. The device sends an application to the DHCP server, and the server provides a DHCP message to the device. In the DHCP message, the assigned IP address, host address (gateway address), DNS server address, Subnet mask, lease renewal time and other information. The lease time (lease time) means that the IP address is not permanently used by this device. At 50% lease time, the device needs to actively send a Request message to renew the lease. After the DHCP server replies with an ACK message, the IP address can continue to be used. If the lease renewal request is sent at 50% of the lease time, if the DHCP server does not reply, the device will send it again when the time reaches 67.5% of the lease renewal time... Until the 100% lease time does not receive an ACK message from the server, the device will The IP address will be discarded, and the discovery request will be resent to apply for the address. For details, refer to the prior art, which will not be repeated here.

205. Set domain name information based on the target IP address.

Specifically, the domain name information is set based on the target IP address, so as to establish a connection with the server. Specifically, the DNS address information carried in the DHCP message can be configured to the DNSmasq module. DNSmasq supports DNS configuration and DHCP server. This step Reference may be made to the prior art, and details are not repeated here.

206. Determine the target communication protocol according to the upgrade instruction instruction.

Specifically, the target communication protocol is determined according to the upgrade instruction instruction. The target communication protocols are File Transfer Protocol (FTP, File Transfer Protocol), File Transfer Protocol (FTPS) supporting Transport Layer Security, Hyper Text Transfer Protocol (HTTP, Hyper Text Transfer Protocol), Hyper Text Transfer Protocol (Hyper Text Transfer Protocol) Protocol over SecureSocket Layer) or SSH File Transfer Protocol (SFTP, SSH FileTransfer Protocol). The specific communication protocol settings can be determined according to the device conditions, which are not limited here.

It is worth noting that in order to support the smooth operation of the SFTP protocol on the device, certain adjustments can be made to the Android system. Specifically, the supporting software library package and function library can be transplanted into the system, which will not be repeated here.

207. Establish a data connection with the target server based on the target communication protocol and domain name information.

Specifically, a data connection with the target server is established based on the target communication protocol and domain name information. The target server can be set by the operator. Since it supports a specific upgrade of the Android system, it is used to deal with some special situations, which is not limited here. The network address of the target server may also be pre-written with an upgrade instruction, which is not specifically limited here.

208. Receive an upgrade data packet sent by the target server.

Specifically, after the data connection is established between the target server and the Android system to be upgraded, the upgrade data package sent by the target server is received, wherein the data of the upgrade data package is determined according to the system version of the current Android system. Before the upgrade data package sent by the target server, the target server and the Android system can also communicate to determine the required upgrade data package version, so that the upgrade process can be carried out smoothly, which can be determined according to the actual situation, which is not limited here. The upgrade data package can be stored in a specific upgrade package storage path in the Android system to support the smooth progress of the upgrade process.

209. Complete the Android system upgrade process based on the upgrade data package in the recovery mode.

Specifically, after receiving the upgrade data package, the system completes the Android system upgrade process based on the upgrade data package in the recovery mode. For the specific upgrade process, reference may be made to the upgrade process in the Android system recovery mode in the prior art, which will not be repeated here.
