Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a method for upgrading a system, as shown in fig. 1, the method includes:
101. and the terminal acquires the system upgrade package.
When the system of the terminal needs to be upgraded, the system upgrade package is acquired first, and then the subsequent upgrade operation is performed. In practical application, the terminal system upgrade mainly includes two modes: online system upgrade and offline system upgrade. If the terminal carries out online system upgrade, the terminal downloads a system upgrade package online through a network; if the terminal is in off-line upgrading, the user can download the system upgrading package on the computer when the terminal is in a shutdown state, and then copy the system upgrading package into the SD card of the terminal through the data line, so that the system upgrading package is obtained.
It should be noted that the terminal may be a mobile phone of an Android system, a tablet computer of the Android system, or other devices.
In addition, when the system is upgraded in the OTA upgrade manner, the system upgrade package acquired by the terminal may be referred to as an OTA upgrade package.
102. After entering the system recovery mode, the backup data in the buffer is searched.
The system recovery mode is a mode that can modify system data, and in this mode, a new system can be refreshed, an existing system can be backed up or upgraded, and factory settings can be recovered. Therefore, when the system is to be upgraded, the system recovery mode needs to be entered first, and the system upgrade package can be operated to realize the system upgrade.
In addition, the backup data mentioned in this step is data for the system to automatically backup the application installation package into the buffer. Specifically, the application client sends a request for backup and recovery of application data to a backup manager service through a backup manager object, and the backup manager service performs backup and recovery operations on the application installation package after receiving the request.
In practical applications, the backup data obtained by the system automatically backing up each application package is stored in a specific folder (e.g., backup folder) of the buffer. Therefore, when the terminal searches the backup data, whether the buffer area contains the specific folder or not is searched first; if the specific folder is included, whether data are stored under the folder or not is continuously checked, and if the data are stored under the folder, the data stored under the folder are determined as backup data.
103. And if the backup data is found in the buffer area, deleting the backup data.
Since the backup data in the buffer area is deleted without affecting the system, the backup data can be deleted in order to expand the range of the remaining storage space of the buffer area required in the system upgrading process.
104. And running a system upgrading package based on the buffer zone after the backup data is deleted so as to realize system upgrading.
After the backup data in the buffer area is deleted, the residual storage space in the buffer area is increased, and at the moment, the system upgrading package is operated based on the buffer area, so that the data generated in the operation process can be stored in the residual storage space of the buffer area, and the system upgrading is realized.
It should be noted that, when the terminal does not find the backup data, the system upgrade package is directly run to implement system upgrade.
The method for upgrading the system provided by the embodiment of the invention can firstly search whether the buffer area contains backup data or not after the terminal acquires the system upgrading packet and enters the system recovery mode, and delete the backup data if the buffer area contains the backup data, so that the residual storage space in the buffer area is increased, further more data storage spaces can be provided for the system upgrading packet in the subsequent upgrading process of operating the system upgrading packet based on the buffer area, and the success rate of system upgrading is improved.
Furthermore, for the two upgrading modes of online system upgrading and offline system upgrading, the difference exists in the aspect of obtaining the system upgrading package, and the difference also exists in the aspect of entering the system recovery mode. The following describes two specific implementation manners for entering the system recovery mode:
the first method comprises the following steps: if the terminal executes the online system upgrade, the system is restarted to enter a system recovery mode after receiving an online upgrade instruction.
Specifically, the terminal downloads the system upgrade package on line through the network; after the system upgrade package is downloaded, the terminal displays prompt information for allowing a user to select whether to perform system upgrade; after the user clicks the system upgrade button, the terminal receives the online upgrade execution command and restarts the system to enter a system recovery mode.
It should be noted that, if the terminal is a terminal of an Android system, the Android Java (Android Java) layer is passed through in the process of performing the system recovery mode by restarting the system.
Further, in the process of restarting the system to enter the system recovery mode, the terminal writes the storage location of the system upgrade package, the version number of the system upgrade package, and other basic information into the buffer region, so that the system upgrade package can be found in the subsequent system upgrade process, so that the storage space in the buffer region also needs to be used in the process of restarting the system to enter the system recovery mode, but in practical application, the buffer region may be full or the remaining space of the buffer region may be insufficient. Therefore, in order to ensure that the terminal can successfully write the basic information into the buffer, the embodiment of the invention provides the following scheme: before restarting the system and entering the system recovery mode, searching the backup data in the buffer area, and if the backup data is searched in the buffer area, deleting the backup data.
Specifically, after the terminal receives the online upgrade instruction, whether the buffer area contains backup data or not is firstly searched, if the buffer area contains the backup data, the backup data are deleted, and the system is restarted to enter a system recovery mode; if the backup data does not exist, the system is directly restarted to enter a system recovery mode.
And the second method comprises the following steps: and if the terminal executes offline system upgrade, entering a system recovery mode after shutdown and when a preset condition is triggered.
Wherein the preset condition is triggered by the volume up key and the on-off key being triggered simultaneously. That is, when the terminal is in the power-off state, the user can simultaneously press the volume up key and the on-off key on the terminal to enable the terminal to enter the system recovery mode.
Further, in practical applications, the backup data that is automatically backed up by the system for the application package is stored in the backup folder of the buffer, so that the specific implementation manner for deleting the backup data is as follows: and the terminal empties the backup folder in the buffer.
Further, according to the above method embodiment, another embodiment of the present invention further provides a device for system upgrade, which is applied in a terminal. As shown in fig. 2, the apparatus includes: an acquisition unit 21, a search unit 22, a deletion unit 23, and an execution unit 24. Wherein,
an obtaining unit 21, configured to obtain a system upgrade package;
when the system of the terminal needs to be upgraded, the obtaining unit 21 obtains the system upgrade package first, and then performs the subsequent upgrade operation. In practical application, the terminal system upgrade mainly includes two modes: online system upgrade and offline system upgrade. If the terminal performs online system upgrade, the obtaining unit 21 downloads a system upgrade package online through a network; if the terminal performs offline upgrade, when the terminal is in a shutdown state, the user may download the system upgrade package from the computer, and then copy the system upgrade package to the SD card of the terminal through the data line, so that the obtaining unit 21 obtains the system upgrade package.
The searching unit 22 is configured to search backup data in the buffer after entering the system recovery mode, where the backup data is data for the system to automatically backup the application program installation package into the buffer;
the system recovery mode is a mode that can modify system data, and in this mode, a new system can be refreshed, an existing system can be backed up or upgraded, and factory settings can be recovered. Therefore, when the system is to be upgraded, the system recovery mode needs to be entered first, and the system upgrade package can be operated to realize the system upgrade.
A deleting unit 23 configured to delete the backup data when the searching unit 22 finds the backup data in the buffer;
and the running unit 24 is configured to run the system upgrade package based on the buffer area after the deleting unit 23 deletes the backup data, so as to implement system upgrade.
The device for upgrading the system provided by the embodiment of the invention can firstly search whether the buffer area contains backup data or not after the terminal acquires the system upgrading packet and enters the system recovery mode, and delete the backup data if the buffer area contains the backup data, so that the residual storage space in the buffer area is increased, further more data storage spaces can be provided for the system upgrading packet in the subsequent upgrading process of operating the system upgrading packet based on the buffer area, and the success rate of system upgrading is improved.
Further, as shown in fig. 3, the apparatus further includes:
a first entering unit 25, configured to, if online system upgrade is performed, restart the system to enter a system recovery mode after receiving an online upgrade instruction;
specifically, the obtaining unit 21 may first download the system upgrade package on line through the network; after the system upgrade package is downloaded, the terminal displays prompt information for allowing a user to select whether to perform system upgrade; after the user clicks the system upgrade button, the first entering unit 25 receives the online upgrade execution command and restarts the system to enter the system recovery mode.
A second entering unit 26, configured to enter a system recovery mode after shutdown and when a preset condition is triggered if an offline system upgrade is performed.
Further, in the process of restarting the system to enter the system recovery mode, the terminal writes the storage location of the system upgrade package, the version number of the system upgrade package, and other basic information into the buffer region, so that the system upgrade package can be found in the subsequent system upgrade process, so that the storage space in the buffer region also needs to be used in the process of restarting the system to enter the system recovery mode, but in practical application, the buffer region may be full or the remaining space of the buffer region may be insufficient.
Therefore, in order to ensure that the terminal can successfully write the basic information into the buffer, the first entering unit 25 is further configured to search for the backup data in the buffer before the system is restarted to enter the system recovery mode, and delete the backup data if the backup data is found in the buffer.
Further, the preset condition is triggered by simultaneously triggering the volume up key and the on-off key.
Further, a deleting unit 23 is configured to empty the backup folder in the buffer.
