Detailed Description

In order to make the objects, technical solutions and advantages 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 accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.

In the prior art, an intelligent terminal usually only provides an upgrade entrance of an application system, and free switching between two system versions cannot be performed. When the application system is upgraded, a user needs to confirm the complex operations such as upgrading, upgrading package downloading and the like, upgrading experience is influenced, and the upgrading rate of the application system is low.

Since the intelligent terminal generally does not provide a recovery entry for the operation version system, a common user cannot recover the current operation version system to the old version system. Some users restore the version system by means of a flush. When the system test engineer needs to restore the version system, the system test engineer can only reinstall the installation package of the version system to restore the version system. After the user installs the updated version, the problems of application blocking, flash quit, unsmooth interaction interface, non-adaptation of the interaction interface and the like are often caused because the existing software on the intelligent terminal does not support or is incompatible with a certain function of the new operation version system, and the version of the application system needs to be degraded at the moment.

In order to solve the above technical problems, the present invention provides a method, an apparatus, a device and a computer readable medium for replacing a system version, and the specific technical solution is as follows:

as shown in fig. 1, a method for replacing a system version includes:

and S1, monitoring the operation behavior of the user on the terminal, wherein the terminal is provided with a first version system.

As described above, the first version system is an application system currently installed in the smart terminal used by the user, such as a desktop management system, a specific application system, an operating system, and the like. The operation behaviors of the user refer to all operation behaviors of the user on the intelligent terminal on the premise that the first version system is installed on the intelligent terminal, and specifically include an operation gesture, a trigger control sequence and the like. The user behavior monitoring can be realized by adopting a buried point method or by utilizing an auxiliary tool such as an Accessibility Service.

And S2, judging whether the operation behavior meets the replacement condition of the system version.

The replacement condition of the system version may include: the control selects a condition, a validation condition, or a combination of both. Wherein the control selection condition may include: and selecting a preset control and/or a preset control selection sequence. The verification conditions may include: fingerprint verification, short message verification and the like of a user at a preset position. The replacement condition can be set by the service provider and can not be modified, and can also be set by the user.

In one embodiment, step S2 specifically includes:

Specifically, the preset control to be selected may be set in the screen alone, or the existing control on the screen and the selection sequence are used as the control selection condition.

Specifically, in an embodiment, the determining whether the operation behavior meets the control selection condition in the replacement condition includes:

Above-mentioned, the controlling part of four angular point positions department is respectively: the control of upper left corner, upper right corner, lower right corner, left lower corner department, four controls all independently set up in intelligent terminal's screen. The selection order of the four controls can be set as follows: upper left corner, upper right corner, lower left corner. Therefore, as long as the user sequentially triggers the controls in sequence, the next step is carried out.

In the above, it should be noted that, the technical solution disclosed in the present invention can solve two technical problems of version upgrade and version recovery of a system, and therefore, as a case, the replacement condition may include: the version upgrade condition and the version restore condition. Step S2 may specifically include determining whether the operation behavior satisfies the version-up condition or the version-up condition.

And S3, if the operation behavior meets the replacement condition, searching a second version system.

The second version system may be an application system with a system version higher or lower than that of the first version system, and it should be noted that the two are different versions of the same application system.

In one embodiment, step S3 specifically includes:

Further, based on the present invention, two functions of system version upgrade and system version restore can be solved, so as a case, step S3 may include:

if the operation behavior meets the replacement condition, generating system version replacement information;

and searching the second version system according to the replacement information.

As described above, the precondition of the first case of step S3 is that the replacement condition includes two types, i.e., a version-up condition and a version-up condition. If the operation behavior meets the version upgrading condition, system version upgrading information is generated, and if the second version system is searched, the application system with the version level higher than that of the first version system is searched. If the operation behavior meets the version recovery condition, system version upgrading information is generated, and if the second version system is searched, the application system with the version level lower than that of the first version system is searched.

The first case of step S3 is applicable to the replacement of the application systems with multiple versions stored in the system installation package storage file, but the replacement condition and the replacement information need to be distinguished, and the search process is complicated.

Or, as another case, the step S3 may include:

and comparing the versions of the first version system and the second version system, and executing the next step according to the version comparison result.

The second condition is that the system installation package storage file only stores one or two installation packages of the application systems, and when one installation package is stored, the system installation package storage file is an installation package of a non-current installation application system, and when two installation packages are stored, the system installation package storage file includes an installation package of a non-current application system and an installation package of a current application system. If the system version stored in the system version storage file is higher than the system version installed at the current intelligent terminal, the system version is upgraded, and if the system version stored in the system version storage file is lower than the system version installed at the current intelligent terminal, the system version is recovered.

The second case of step S3 is only applicable to the replacement of the application system storing two versions in the system installation package storage file, but the search process is simple and fast.

And S4, modifying the starting priority of the second version system and the first version system, starting the corresponding system version according to the starting priority after receiving a restarting instruction of a user, and completing the replacement.

The starting priority is a setting item of the application system, and represents the version of the application system which is started preferentially when the intelligent terminal is started. It should be noted that after the start priorities of the systems of different versions are modified, the intelligent terminal needs to be restarted to complete the replacement operation, the start priority setting item generally only includes a high version and a low version, and the start priority of the first version system before modification is high, so that the intelligent terminal currently uses the first version system, and the start priority of the second version system after modification is high, so that the intelligent terminal starts the second version system when restarting, thereby achieving the purpose of replacing the systems of different versions.

In one embodiment, step S4 specifically includes: the starting priority of the second version system is changed to a high level, and the starting priority of the first version system is changed to a low level.

It should be noted that, in S1-S4 disclosed in the present invention, a method for replacing a system version when an intelligent terminal stores at least one application system of a version other than a currently used version is disclosed, and when a system service provider provides a new upgraded application system, that is, a third version system, a user needs to load an installation package of the third version system first and then install the system. When the system version currently installed on the intelligent terminal is not the version closest to the system of the third version, the system version currently installed on the intelligent terminal needs to be replaced by the version system closest to the system of the third version.

Based on the above method, in an embodiment, when the version level of the second version system is lower than the version level of the first version system, in order to install the newly upgraded version system, the method disclosed by the present invention further includes:

receiving an upgrading instruction fed back by a user, and installing a first version system to enable the first version system to replace a second version system;

As described above, the installation of the first version system includes: and searching the first edition system and installing the first edition system. Installing the third version system may include: and downloading the third version system and installing the third version system.

In the method for replacing the system version disclosed by the embodiment of the invention, the effect of quickly replacing the systems of different versions is realized by monitoring the user behavior and modifying the setting items of the starting priorities of the systems of different versions, so that the user can conveniently switch the application systems. And the selected control and the selected sequence are used as the replacement conditions of the system version, and the replacement is carried out by triggering the replacement conditions, so that the replacement operation of a user is more convenient and faster. The system version is triggered to be replaced by selecting the controls near the four corners of the screen and selecting the sequence, so that system replacement caused by misoperation of a user can be prevented. On the basis, the invention also provides a method for upgrading the new application system, so that the technical scheme disclosed by the invention is also suitable for replacing the newly developed application system.

As shown in fig. 2, based on the above method for replacing a system version, the present invention further includes a device for replacing a system version, including:

the monitoring module 201 is configured to monitor an operation behavior of a user on a terminal, where the terminal is equipped with a first version system.

And the replacing module 204 is configured to modify the starting priorities of the second version system and the first version system, and after receiving a restart instruction from a user, start a corresponding system version according to the starting priority to complete replacement.

The monitoring module 201 may specifically use a buried point method or utilize an auxiliary tool such as an Accessibility Service to implement the operation behavior monitoring. The replacement condition of the system version set in the determination module 202 may include: the control selects a condition, a validation condition, or a combination of both. The searching module 203 searches the second version system, specifically, searches the installation package of the second version system. The replacement module 204 is mainly used to modify the setup items of the boot priorities of different versions of the system.

In one embodiment, the determining module 202 is specifically configured to:

Further, in an embodiment, the determining module 202 is specifically configured to:

In an embodiment, the search module 203 is specifically configured to:

The device can be arranged in the hardware equipment independently or can be embedded in a management system of the application system.

The following describes a method for replacing the version of the disclosed system in detail with reference to a specific implementation scenario of recovering a low-version android desktop application (launcher. apk):

as shown in fig. 3, for the smart terminal, clickable transparent buttons are added at 4 corners (top left, top right, bottom right, and bottom left) of the launcher system-level application respectively, an available high-version application system launcher a.apk and an available low-version application system launcher b.apk are stored in the system/app directory of the smart terminal system, and the application systems can be automatically installed after being started. It should be noted that the package names of the launcher a.apk and launcher b.apk installation packages are the same, but the versions are different.

And the framework layer records a version system with high starting priority and registers and monitors the sequential change condition of 4 buttons on the desktop of the screen.

When the user clicks 4 buttons in sequence (upper left, upper right, lower right and lower left), the framework layer monitors that the user presses the button "lower left", and then searches for a version system launcher B.apk with a low starting priority. The launch priority of launcher b.apk is set to "high" and the launch priority of launcher a.apk is set to "low". After restarting the system, the device drops to a lower version of launcher b.
