Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the present disclosure, unless otherwise specified, the use of the terms "first", "second", etc. to describe various elements is not intended to limit the positional relationship, the timing relationship, or the importance relationship of the elements, and such terms are used only to distinguish one element from another. In some examples, a first element and a second element may refer to the same instance of the element, and in some cases, based on the context, they may also refer to different instances.
The terminology used in the description of the various described examples in this disclosure is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the elements may be one or more. Furthermore, the term "and/or" as used in this disclosure is intended to encompass any and all possible combinations of the listed items.
In the disclosure, the processes of collecting, storing, using, processing, transmitting, providing, disclosing and the like of the personal information of the related users are all in accordance with the regulations of related laws and regulations, and do not violate the customs of the public order.
The operating system of an electronic device typically needs to be updated and upgraded many times. However, the current electronic devices do not provide an operating system switching function. After the electronic equipment is upgraded to the operating system of the new version, the electronic equipment cannot be returned to the operating system of the old version for use.
If a user finds that a new version of the operating system is incompatible with some applications or that a fatal problem exists with the new version of the operating system that does not meet the user's normal usage requirements, the new version of the operating system is not as good as the old version, and the user may wish to rollback the operating system to the old version. However, as mentioned above, since the electronic device does not provide the os switching function, the user can only implement the system version rollback by means of a flush (i.e., reinstalling the system).
The technical threshold of the brushing machine is high, and the operation is complex. If the user swipes himself, it is likely that the machine will fail to be swiped, so that the electronic device cannot be normally started (namely, the device is colloquially called to be changed into a brick). If the user sends the electronic device to the after-sales service place for refreshing, the user needs to consume a large amount of waiting time because the time period of the after-sales service is usually long, and the problems of user data privacy and security exist.
Therefore, the embodiment of the disclosure provides a system switching method for an electronic device, which can enable a user to conveniently and quickly switch an operating system of the electronic device, and meet the use requirements of the user. The system switching method of the embodiment of the disclosure can switch the operating system of the electronic device from a new version to an old version, thereby realizing system rollback; the operating system of the electronic equipment can be switched from the old version to the new version, so that system upgrading is realized.
Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
Fig. 1 shows a flow diagram of a system switching method 100 for an electronic device according to an embodiment of the disclosure. The method 100 is performed in an electronic device.
The electronic devices may be various types of computer devices, such as portable handheld devices (including cell phones, tablets, Personal Digital Assistants (PDAs), etc.), general purpose computers (such as personal computers and laptops), workstation computers, wearable devices (including smart watches, smart glasses, etc.), in-vehicle smart devices, self-service terminal devices, service robots, gaming systems, thin clients, various messaging devices, sensors or other sensing devices, and so forth. These computer devices may run various types and versions of software applications and operating systems, such as MICROSOFT Windows, APPLE iOS, UNIX-like operating systems, Linux, or Linux-like operating systems (e.g., GOOGLE Chrome OS); or include various Mobile operating systems such as Android, iOS, MICROSOFT Windows Mobile OS, Windows Phone, etc.
As shown in fig. 1, the method 100 includes:
and step 130, restarting the electronic equipment so as to operate the target operating system based on the starting flag bit.
According to the embodiment of the disclosure, the starting flag bit can be modified and the electronic device can be restarted based on the system switching operation of the user, so that the quick switching of the operating system is realized, the user can flexibly and conveniently select the required operating system, and the use experience of the user on the electronic device is improved.
In an embodiment of the present disclosure, a storage space of a memory of an electronic device is divided into a plurality of areas, each area for storing a specific type of data. For example, the memory space of the electronic device may be divided into a boot partition (bootloader) for storing a boot program and a boot parameter, at least two system partitions (slots) for storing an operating system, a user data partition (userdata) for storing user data including an application installed by a user and data generated when the application is used, and the like. Each system partition is used to store an operating system. It should be noted that the operating systems stored by different system partitions may be the same or different.
At least two operating systems are stored in the electronic device. The at least two operating systems include a currently running operating system (i.e., a "current operating system") and at least one currently non-running available operating system (i.e., a "standby operating system"). As described above, the current operating system and each of the standby operating systems are stored in the corresponding system partitions.
The electronic equipment also stores a starting zone bit. The start flag is used for indicating an operating system operated by the electronic equipment. The value of the start flag bit may be modified during the current operating system run. After the value of the start flag is modified, the start flag is used to indicate an operating system that is run when the electronic device is started next time, that is, the operating system that is run after the electronic device is restarted. The boot flag, which is one of the boot parameters, is stored in the boot partition.
In step 110, a target operating system is determined from the at least one standby operating system in response to a system switch operation by a user in the current operating system.
The system switching operation may be any Graphical User Interface (GUI) interaction, such as clicking, long-pressing, dragging, and the like.
According to some embodiments, in a case where only one standby operating system is stored in the electronic device (accordingly, the electronic device includes two system partitions), a system switching component may be provided in the interactive interface of the current operating system, and accordingly, the standby operating system may be determined as the target operating system in response to the user's interactive operation on the system switching component. Therefore, the switching function between the two operating systems can be realized, namely, the current operating system is switched to the standby operating system.
Specifically, an event to be monitored may be bound for the system switching component, and a callback function to be executed when the event occurs may be set. The event to be monitored is the interactive operation of the user for the system switching component, and the callback function defines a series of operations to be executed after the interactive operation of the user for the system switching component is monitored, such as determining a target operating system (step 110), modifying a start flag (step 120), restarting the electronic device (step 130), and the like.
The system switch component may be, for example, a Button (Button), a view component (e.g., text view, image view ImageView), or the like. The interaction operation may be, for example, a click operation. Accordingly, an onClick click event can be bound for Button (or TextView, ImageView). When the user clicks the Button (or TextView or ImageView), the user is considered to initiate a system switching request, and the standby operating system is used as a target operating system to be switched to.
Fig. 2A, 2B show schematic diagrams of the interactive interfaces 210, 220 in case the electronic device has only one standby operating system stored.
As shown in FIG. 2A, interactive interface 210 is a "system setup" interface for an electronic device. The interface 210 includes components 211 and 216, each of which corresponds to a system functionality option. The user can set the corresponding system function by clicking on the component. For example, the user may click on the "date and time" component 212 to enter a date and time setting interface to set the date and time.
In fig. 2A, a "system switch" component 214 is used to implement the system switching method of the embodiment of the present disclosure, which can switch the electronic device from the current operating system to the standby operating system. Specifically, in the case where the version number of the current operating system is higher than the version number of the standby operating system, system rollback (i.e., switching from the high-version system to the low-version system) may be implemented; in the event that the version number of the current operating system is lower than the version number of the alternate operating system, a system upgrade (i.e., a switch from a low-version system to a high-version system) may be implemented.
The component 214 binds an onClick event that the electronic device continues to listen for. When the user clicks the component 214, a click event of the component 214 is triggered, and after the electronic device monitors the click event, step 110 may be executed, in response to the click operation of the user, the standby operating system is determined as the target operating system to be switched to, and system switching is completed through subsequent steps 120 and 130.
According to other embodiments, after the electronic device monitors the click event of the component 214, the interface 220 shown in fig. 2B may be further entered to present a prompt message 221 to the user for prompting the user about the version number of the target operating system to which the user is going to switch. When the user clicks the "ok" button 223 (the button 223 is bound with a click event), step 110 may be performed, in response to the user's click operation, determining the standby operating system (2.0 version system) as the target operating system, and completing the system switching through the subsequent steps 120, 130. When the user clicks the "cancel" button 222 (the button 222 is bound with a click event), the user returns to the interface 210 and continues to monitor the click operation of the "system switch" component 214 by the user.
According to other embodiments, in a case that at least two standby operating systems are stored in the electronic device (accordingly, the electronic device includes at least three system partitions), a standby system list may be displayed in the interactive interface of the current operating system, the standby system list including a plurality of list items, each list item corresponding to one standby operating system. Correspondingly, in response to the selection operation of the user on the list item in the standby system list, the standby operating system corresponding to the list item is determined as the target operating system. Thus, a switching function between a plurality of operating systems can be realized.
For example, FIG. 2C shows a schematic view of interactive interface 230 in the case where the electronic device stores two alternate operating systems. The interface 230 may be displayed, for example, after the user clicks on the "system toggle" component 214 in the aforementioned interface 210.
As shown in fig. 2C, a prompt message 231 is displayed in the interface 230 for prompting the user about the version number (2.2 version) of the current operating system and the operation that the user can perform (i.e., selecting the version of the system that the user wishes to switch to). A standby system list is displayed in interface 230 and includes list items 232 and 233. List item 232 corresponds to alternate operating system 1 version 2.0 and list item 233 corresponds to alternate operating system 2 version 2.3. The user can select the standby operating system to which the user wants to switch by clicking the corresponding list item, and the standby operating system selected by the user is the target operating system.
According to some embodiments, the version number of the target operating system can be lower than that of the current operating system, so that the version rollback of the operating system can be realized, and a user can fast and conveniently rollback to an old version system for use when the new version system has problems and cannot meet the use requirements, without waiting for the next system upgrade and repair problems or flashing.
According to some embodiments, in a case that a system upgrade function already exists in an electronic device, considering that a user may easily implement system switching from an old version to a new version (for example, a manner of detecting a new version system and performing OTA download upgrade may be implemented), the system switching method according to the embodiments of the present disclosure may be implemented only as a system rollback method, and a system rollback function is provided, that is, a system is switched from a new version system to an old version system.
2D-2F illustrate schematic diagrams of the electronic device interaction interface 240 and 260 in a system fallback scenario.
As shown in FIG. 2D, interface 240 is a "system setup" interface for an electronic device. The interface 240 includes components 241-246, each of which corresponds to a system functionality option. The user can set the corresponding system function by clicking on the component.
In FIG. 2D, a "system rollback" component 244 is used to implement the system rollback method of embodiments of the present disclosure. Component 244 has bound an onClick event that the electronic device continues to listen for.
In the event that only one alternate operating system is stored in the electronic device and the alternate operating system has a version number lower than the current operating system, the "system rollback" component 244 in the interface 240 may click. When the user clicks on component 244, a click event of component 244 is triggered. After monitoring the click event, the electronic device may execute step 110, determine the standby operating system as the target operating system to be rolled back to in response to the click operation of the user, and complete the system rolling back through subsequent steps 120 and 130.
According to other embodiments, after the electronic device hears the click event of the component 244, the interface 250 as shown in fig. 2E may be further entered to present a prompt message 251 to the user for prompting the user for the version number of the target operating system to which the user is going to rollback. When the user clicks the "ok" button 253 (the button 253 is bound with a click event), step 110 may be performed, in response to the user's click operation, determining the standby operating system (2.0 version system) as the target operating system, and completing the system rollback through the subsequent steps 120, 130. When the user clicks the "cancel" button 252 (the button 252 is bound with a click event), the user returns to the interface 240, and continues to monitor the clicking operation of the "system rollback" component 244 by the user.
In the case where only one standby operating system is stored in the electronic device and the version number of the standby operating system is higher than that of the current operating system, since an operating system of a version lower than that of the current operating system does not exist in the electronic device, system rollback cannot be performed. In this case, the "system rollback" component 244 in the interface 240 may be set to grey and may not be clickable, according to some embodiments.
In the case where at least two alternate operating systems are stored in the electronic device, interface 260 may be entered when the user clicks on "system rollback" component 244 in interface 240. A prompt message 261 is displayed in the interface 260 to prompt the user for the version number of the current operating system (version 2.2) and the operations that the user can perform (i.e., select the version of the system that the user wishes to rollback to). A standby system list is displayed in interface 260 and includes list items 262 and 263. List item 262 corresponds to alternate operating system 1 version 2.0 and list item 263 corresponds to alternate operating system 2 version 2.3.
The backup operating system may have a version number lower or higher than the current operating system. According to some embodiments, in the standby system list, the status of the list item corresponding to the standby operating system with the version number lower than that of the current operating system is set to be selectable, and the status of the list item corresponding to the standby operating system with the version number higher than that of the current operating system is set to be unselected and displayed in grey, so that the user is prompted about the system version which can be currently backed up.
For example, in the interface 260, the version number 2.0 of the standby operating system 1 corresponding to the list item 262 is lower than the version number 2.2 of the current operating system, so the status of the list item 262 is optional, that is, the user may click on the selected list item 262, in response to the selection operation of the user, determine the standby operating system 1 as the target operating system to be rolled back to, and complete the system rolling back through the subsequent steps 120 and 130. The version number 2.3 of the standby operating system 2 corresponding to the list item 263 is higher than the version number 2.2 of the current operating system, so the status of the list item 263 is grey and unselected.
In step 120, the value of the start flag bit is set to the identity of the target operating system. According to some embodiments, the identification of the target operating system may be the address of the system partition in which the target operating system is located (i.e., the target system partition), i.e., the value of the start flag is set to the address of the target system partition. Therefore, after the electronic equipment is restarted, jumping to the target system partition to execute the code of the target operating system, and running the target operating system.
According to some embodiments, the method 100 further comprises: before restarting the electronic device, the cache data and the user data in the electronic device are cleared. Therefore, the problem of compatibility caused by the existence of data in the operating system before switching after the electronic equipment is restarted can be avoided, and the operating system after switching can be ensured to run normally and stably.
Fig. 3 shows a flow diagram of a system handover procedure 300 (fallback procedure) according to an embodiment of the present disclosure. Before the process 300 is executed, a "system fallback" component may be set in a "system setup" interface, an onClick click event is bound to the system fallback component, and a callback function that needs to be called when the click event occurs is set. In the Android system, the callback function may be implemented as an HIDL (hal (hardware Abstraction layer) Interface Description Language) Interface (hereinafter, abbreviated as "HIDL Interface") of the Framework layer.
The HIDL interface is used for modifying a start flag bit, cleaning a cache and user data, and restarting the electronic equipment. It can be understood that the HIDL interface has an access right (i.e., a read-write right) to start the flag bit by adjusting the SELinux policy of the Android system.
In the embodiment shown in fig. 3, two operating systems (i.e., a current operating system and a standby operating system) are stored in the electronic device, and the version number of the current operating system is higher than that of the standby operating system, i.e., the current operating system is a new version system and the standby operating system is an old version system.
As shown in FIG. 3, in step 301, the user clicks the "System Back" button in the "System settings" interface in the current operating system (new version system), triggering an onClick event.
In step 302, in response to the onClick event, the HIDL interface corresponding to the onClick event is called.
In step 303, the boot flag in the BootLoader boot program is rewritten, and the value of the boot flag is modified to the address of the system partition where the old version system is located.
In step 304, a request is made to enter a Recovery system (Recovery system is a piece of program code for data cleaning) for data cleaning.
In step 305, the Recovery system is entered to perform data cleaning to clean data such as user data, App cache, Framework cache, and the like.
In step 306, the Recovery system completes data cleaning and restarts the electronic device.
In step 307, after the electronic device is restarted, the BootLoader bootstrap program is loaded and executed first.
In step 308, the BootLoader bootstrap program reads the value of the boot flag, and determines the address of the target system partition to be booted.
In step 309, the BootLoader bootstrap program loads the operating system code (i.e., the old version system) in the target system partition as indicated by the boot flag.
In step 310, the loaded code is executed, thereby starting and running the old version system.
According to the embodiment of the disclosure, a system switching device for an electronic device is also provided.
