The system version number is generated according to the generation time of the system program, so that the system version numbers of different system versions are different, and whether the system program started at the time is the same as the system program started at the last time can be determined according to the system version number.
In some embodiments, the system version number of the currently running system program is stored in the form of a read-only attribute (ro.vt.software.version) configuration item in the following format: [ ro.vt.software.version ]: xxxxxx ], wherein xxxxxx represents a system version number, such as AL0405, BL0418, and the like. The system version number can be obtained through a standard Android system interface systemoproperties.
In some embodiments, the system version number of the system program of the last system boot is stored in the Android standard property value per si st. The system version number can be obtained through systemoproperties.
In some embodiments, if it is determined that the system version number of the currently running system program is different from the system version number of the system program started last time, it indicates that the current system start is the first start of the system program of the new version, and the system software needs to be optimized, for example, the Odex optimization is performed, so as to avoid the abnormal operation of the system software.
Step S230: and if the values of the current fingerprint parameters are different from the values of the historical fingerprint parameters, optimizing the system software aiming at the current system version parameters.
In some embodiments, if the current fingerprint parameter is different from the historical fingerprint parameter, it indicates that the currently running system program is different from the system program version running at the last system startup, the current system startup is the first startup of a new version, and the system software needs to be optimized, for example, the Odex optimization is performed to avoid the system software running, and if the current system version number is also the same as the historical system version number, it indicates that the current system startup and the last system startup are all the system program of the same version, and the system software does not need to be optimized.
In some embodiments, the odex is a runnable file extracted from the apk, that is, the classes.
According to the embodiment, in the system starting process, the comprehensive judgment is carried out on the fingerprint parameters and the system version number, the scene judgment of the system starting is enriched, the problem that the system software is abnormally operated due to the fact that the system program is a new version and is not optimized is solved, and the system upgrading experience is improved.

In some embodiments, the display device is configured to set, at the end of the system upgrade, a last.
Step S303: and if the value of the last system version parameter is null, judging whether an upgrading strategy exists.
In some embodiments, when the last system version parameter is null, the display device may interact with the server to obtain whether a new upgrade policy exists.
Illustratively, the interaction method of the display device and the server may be as follows:
the display device sends a system upgrade request to the server, wherein the system upgrade request can contain the device identification and the current system version number of the display device. The current system version number may be obtained by: get through the standard Android system interface systemoproperties.
After receiving the system upgrade request, the server may obtain the latest system version number corresponding to the device identifier according to the device identifier in the system upgrade request. The server can judge whether the latest system version number is consistent with the system version number of the display equipment, if so, the server returns a request result indicating that no upgrading strategy is available to the equipment, if not, the server generates an upgrading strategy containing the latest system version number and the installation package downloading address of the latest system version number, and feeds the upgrading strategy serving as the request result back to the display equipment.
Step S304: if the upgrade strategy exists, the upgrade prompt is displayed, and whether the user selects 'agreeing to upgrade' is judged.
In some embodiments, if the request result received by the display device from the server includes the upgrade policy, the upgrade alert is generated and displayed according to a system version number in the upgrade policy. The content of the upgrade reminder may be: "new version detected, upgrade not? Agree to upgrade the next statement, "where" agree to upgrade "and" next statement "are controls that may be operable by the user.
