It should be noted that the settings database is data information for storing data in the form of key-value; in each data information, the key is a data index corresponding to system data (or user data). The value is a value corresponding to system data (or user data).

The process of updating system data in a system partition to a settings database by an electronic device is described in detail below with reference to the accompanying drawings.

Firstly, the system data information is preset in a system partition of an operating system before the electronic equipment leaves the factory, and when the electronic equipment leaves the factory for the first time (or called first time), the electronic equipment updates the system data information preset in the system partition into a settings database.

For easy understanding, in the embodiment of the present application, the system data information preset in the system partition of the operating system may be referred to as initial data information when the electronic device is first powered on after leaving the factory. After leaving the factory, the system data information preset in the system partition of the operating system except for each startup after the first startup of the electronic equipment is called first data information.

In other words, when the electronic device is first powered on after leaving the factory, the electronic device updates the initial data information stored in the system partition of the operating system into the settings database. When the electronic equipment is started up for each time after the electronic equipment is started up for the first time, the electronic equipment updates the first data information stored in the system partition of the operating system into the settings database.

Fig. 3 is a schematic flow chart of data updating according to an embodiment of the present application. For example, as shown in fig. 3, when the electronic device is turned on for the first time after leaving the factory, the process of updating the initial data information stored in the system partition of the operating system to the settings database by the electronic device may be implemented by the following steps.

S201, the electronic equipment acquires initial data information.

In some embodiments, the initial data information may be saved under a target path of the operating system. Illustratively, the target path may be settingdefault.

Wherein the initial data information is stored in the form of an extensible markup language (extensible markup language, XML) file under the settings_defaults. That is, the XML file with the initial data information stored under the settingdefaults.

In some embodiments, the electronic device may parse the XML file according to the settingdefault. The initial data information includes a plurality of data indexes (keys) and initial data (value) corresponding to each data index.

S202, the electronic equipment writes the initial data information into a first database.

In some embodiments, the first database may be default settings.

It will be appreciated that the initial data information is stored in the first database in the form of key-value.

Illustratively, the plurality of initial data information stored in the first database is as follows:

<！--2021-09-17 15:11:32，000-->

<！--2021-09-17 15:11:32，000-->

</resources>

taking the above-mentioned < integer accelerometer _rotation= "1"/>, as an example, in the initial data information, the data index is integer accelerometer _rotation, and the initial data is 1.

The foregoing is merely illustrative of the initial data information stored in the first database, and is not meant to limit the present application.

S203, the electronic equipment writes the initial data information into the second database.

In some embodiments, the second database may be settingdb, i.e., settingdb in the above embodiments.

It will be appreciated that the initial data information is stored in the second database in the form of key-value.

It should be noted that, when the electronic device is turned on for the first time after leaving the factory, the plurality of initial data information stored in the first database is the same as the plurality of initial data information stored in the second database. For an illustration of the plurality of initial data information stored in the second database, reference may be made to the above embodiment, and details are not repeated here.

In some embodiments, the second database is partitioned with a plurality of data partitions, and partition identifications (tables) of the initial data information stored in each data partition are different. Taking the example of the second database being partitioned with three data partitions, the three data partitions may include, for example: settingsystem. Xml, settingsecurity. Xml, settingglobal.

Wherein the settingsystem xml may store data information of all users, such as data information of all users of the system, data information of all users of the third party application, and the like. settingjsecure.xml may hold data information of a user having storage rights, such as data information of a user having storage rights and being a system; the user of the third party application does not have the storage authority of the data partition, namely, the settingjsecure.xml cannot store the data information of the user of the system without the storage authority, and cannot store the data information of the user of the third party application. settingglobal xml can hold data information for all users of the system. The user of the third party application does not have the storage authority of the data partition, namely, the settingglobal. Xml cannot store the data information of the user of the third party application.

In some embodiments, each of the plurality of initial data information further includes a partition identification for the electronic device to save the initial data information in a corresponding data partition.

Taking the initial data information as < integer accelerometer _rotation= "1"/> asan example, for illustration, in the case where the initial data information includes partition identification, the initial data may be, for example, < integer accelerometer _rotation= "1" table= "global"/>. Wherein the partition of the initial data information is identified as global. Based on this, the electronic device can write the initial data information into the data partition set_global.xml according to the partition identification of the initial data information.

In some embodiments, individual application packages (android application package, APK) in the electronic device may share the read after the electronic device writes the initial data information to the second database. In other words, each APK in the electronic device may read, through a key, initial data corresponding to the key in the second database. Illustratively, the APK may read that the initial data corresponding to the key is "1" through the key= integer accelerometer _rotation. Subsequently, during the use of the electronic device, the electronic device may modify the initial data stored in the second database through the operation of the user. It should be appreciated that after the electronic device modifies the initial data stored in the second database by user operation, the modified initial data may be referred to as user data.

For example, taking the initial data information as < integer accelerometer _rotation= "1"/>, in the use process of the electronic device, the electronic device may modify the initial data to "0" through the operation of the user, and the modified initial data information is < integer accelerometer _rotation= "0"/>.

It should be appreciated that the modified initial data may be referred to as user data. On this basis, the APK in the electronic device reads that the user data corresponding to the key is "0" through the key= integer accelerometer _rotation.

In some embodiments, the state where the initial data information is a night upgrade is taken as an example, and illustratively, the initial data information is hw_system_light_upgrade_switch=0, that is, the initial state of the night upgrade is 0 (that is, the night upgrade is turned off). However, if the electronic device is in use, the electronic device updates the initial data information to hw_system_right_upgrade_switch=1 through the operation of the user, that is, the night upgrade state is 1 (that is, the night upgrade is turned on). It should be noted that, since the electronic device modifies the initial data through the operation of the user, the initial data is the user data.

S204, the electronic equipment calculates a hash value (hash) of the XML file under the target path, and stores the hash value of the XML file obtained through calculation.

In some embodiments, the electronic device takes the XML file as input, inputs the XML file into a preset algorithm model, and outputs a hash value corresponding to the XML file. Typically, hash values are represented by a string of a combination of letters and numbers.

The preset algorithm model has a function of calculating a hash value corresponding to the XML file. For an example of the preset algorithm model, reference may be made to related technologies, and details are not repeated in the embodiment of the present application.

In one implementation, if a plurality of initial data in the initial data information are stored under different target paths, in S204, the electronic device needs to calculate a hash value of the XML file under each of the plurality of target paths.

The hash values corresponding to the files having different contents are necessarily different. That is, even if the file names of the two files are the same, if the contents of the two files are different, the calculated hash values are different. Based on the above, at each power-on after the electronic device is powered on for the first time, whether the content of the XML file is modified can be determined by judging whether the hash value of the XML file changes. That is, when the hash value of the XML file changes at each power-on after the electronic device is first powered on, the electronic device determines that the content of the XML file is modified, that is, the system data stored in the system partition of the operating system is modified. If the hash value of the XML file is unchanged, the electronic device determines that the content of the XML file is not modified, i.e., the system data stored in the system partition of the operating system is not modified.

Based on the above, at each power-on after the electronic device is powered on for the first time, the electronic device can determine whether the content of the XML file is modified by determining whether the hash value of the XML file changes. If the content of the XML file is modified, the electronic equipment updates the modified XML file to the second database; if the content of the XML file is not modified, the electronic equipment is started normally, and the XML file is updated to the second database.

Fig. 4 is a schematic flow chart of data updating according to an embodiment of the present application. For example, as shown in fig. 4, the process of updating the system data information stored in the system partition of the operating system to the settings database by the electronic device at each power-on after the first power-on may be implemented by the following steps.

S301, the electronic device judges whether the hash value of the XML file under the target path changes.

In some embodiments, the electronic device may calculate a hash value of the XML file in the target path at each boot after the first boot, and compare the hash value of the XML file calculated in the first boot with the hash value of the XML file calculated in the first boot, so as to determine whether the hash value of the XML file in the target path changes.

For example, if the hash value of the XML file under the target path is unchanged, the electronic device is powered on normally, and the XML file does not need to be updated into the second database. If the hash value of the XML file under the target path changes, the electronic device executes S302.

In the embodiment of the present application, when the electronic device is first powered on after leaving the factory, the system data information stored in the operation partition of the operating system is referred to as initial data information. For convenience of distinction, the system data information stored in the operation partition of the operating system at each power-on of the electronic device after the first power-on is referred to as first data information.

In one implementation, if the plurality of first data information is stored in different target paths, in S301, the electronic device may traverse each target path and determine whether the hash value of the XML file in each target path changes.

S302, the electronic equipment acquires the first data information.

In some embodiments, the first data information may be saved under a target path of the operating system. Illustratively, the target path may be settingdefault.

The first data information is stored in the form of an XML file under the setting_defaults.xml path. That is, the XML file having the first data information stored in the settingdefault.

In some embodiments, the electronic device may parse the XML file according to the settingdefault. XML path to obtain the first data information. The first data information comprises a plurality of first data indexes and first data corresponding to each first data index.

S303, the electronic equipment traverses each first data index, and judges whether user data exist in the second database according to the first data index.

The electronic device traverses each first data index, and reads first data corresponding to the first data index from the first data information through the first data index key. If the electronic device can read the first data corresponding to the first data index from the first data information through the first data index key, and the first data corresponding to the first data index key is different from the initial data corresponding to the first data index key stored in the first database, the electronic device judges that the user data exists in the second database.

Accordingly, the electronic device traverses each first data index, and reads the first data corresponding to the first data index from the first data information through the first data index key. If the electronic equipment does not read the first data corresponding to the first data index from the first data information through the first data index key, the electronic equipment judges that the user data does not exist in the second database. Or if the electronic device can read the first data corresponding to the first data index from the first data information through the first data index key, and the first data corresponding to the first data index key is different from the initial data corresponding to the first data index key stored in the first database, the electronic device judges that the user data does not exist in the second database.

In some embodiments, when the electronic device determines that no user data is present in the second database, i.e., non-user data (or second data) is present in the second database. On the basis, the first data information stored in the second database also comprises a plurality of fourth data indexes and second data corresponding to each fourth data index, wherein the second data is not user data generated in the running process of the electronic equipment, namely, the second data is non-user data. Therefore, the electronic device can update the data index of each second data in the first data information, namely, update the fourth data index corresponding to each second data.

It should be noted that, in the embodiment of the present application, the electronic device may use an over-the-air technology (over the air technology, OTA) to upgrade the operating system. In general, when an operating system is upgraded by OTA, user data cannot be modified based on the principle of user data priority. That is, in the use process of the electronic device, if the electronic device modifies the initial data through the operation of the user, the modified initial data is the user data. In the embodiment of the application, the user data is preferentially protected based on the principle of user data priority, so that if the user data exists in the second database, the user data in the second database cannot be modified.

The requirement of the electronic equipment is different under different application scenes. Therefore, the APK in the electronic device needs to modify the first data index key of the second database (i.e. modify the old key to a new key) to meet the needs of the electronic device in different scenarios. As can be seen from the above embodiments, if the electronic device determines that the second database does not have the user data, the electronic device may modify the first data index key in the second database. Illustratively, the electronic device first updates the data index in the first database, and then the electronic device updates the first data index in the second database. That is, the electronic device updates the data index corresponding to the non-user data (or referred to as the second data) in the second database (e.g., updates the fourth data index corresponding to the second data) with respect to the non-user data.

However, if the electronic device determines that the user data exists in the second database, the user data is preferentially protected based on the principle of user data priority, so that the user data cannot be modified. I.e. the electronic device cannot modify the data index corresponding to the user data in the second database for the user data.

In this way, after the operating system of the electronic device is upgraded, since the data index corresponding to the user data in the second database is not modified, and the new key does not correspond to the user data, the electronic device cannot read the user data before the operating system is upgraded when receiving the access request including the new key.

Taking the switch state of the night upgrade as an example for illustration, the initial data information is hw_system_high_upgrade_switch=0, i.e. the initial state of the night upgrade is the off state. However, if the electronic device is in use, the electronic device updates the initial data information to hw_system_right_update_switch=1 through the operation of the user, that is, the night upgrade state is the on state. It should be noted that, since the electronic device modifies the initial data through the operation of the user, the initial data is the user data.

After that, if the APK of the electronic device modifies the key of the user data to be hn_system_high_upgrade_switch, after the operating system of the electronic device is upgraded, the new key does not correspond to the value before the operating system is upgraded because the user data cannot be modified, so that the electronic device cannot read the value of the historical version through the new key, that is, the electronic device cannot read the state of the night upgrade. In this case, the electronic device may default to the off state at night upgrade.

In some embodiments, the electronic device updates the data index of the user data generated during operation of the electronic device by upgrading the operating system in the presence of the user data in the second database. As shown in fig. 5, the data updating method provided by the embodiment of the present application further includes:

S304, after the electronic equipment detects a starting instruction, a configuration file is obtained.

The configuration file comprises a corresponding relation between a second data index and a third data index provided by each first APK in a plurality of first application packages APK of the electronic equipment, wherein the second data index is a data index before upgrading an operating system of the electronic equipment, and the third data index is a data index after upgrading the operating system. I.e. the second data index is the old key before the upgrade of the operating system of the electronic device, and the third data index is the new key after the upgrade of the operating system of the electronic device.

The electronic device analyzes the configuration file and obtains a corresponding relationship between the second data index and the third data index provided by each of the plurality of first application packages APK after the electronic device detects the start-up instruction.

The electronic device analyzes the configuration file, and the correspondence between the second data index and the third data index provided by each of the obtained first APKs in the plurality of first application packages APK is as follows:

it should be noted that the foregoing is merely illustrative of the parsed configuration file, and is not meant to limit the embodiments of the present application.

In some embodiments, when first data of each first APK in the plurality of APKs of the electronic device is updated, the electronic device generates a configuration file according to a second data index before updating the first data and a third data index after updating the first data according to each first APK, and stores the configuration file. That is, the electronic device stores the configuration file prior to the operating system upgrade.

In other embodiments, the electronic device generates the configuration file during an upgrade of the operating system. In an exemplary process, the electronic device collects a second data index and a third data index provided by each first APK in the plurality of APKs in the process of upgrading the operating system, and generates a configuration file.

And subsequently, before or during the process of upgrading the operating system, the electronic equipment updates the configuration file by adopting the fifth data index and the sixth data index provided by the second APK. The fifth data index is a data index before the first data in the second APK is updated, and the sixth data index is a data index after the first data in the second APK is updated.

The first APK and the second APK may be the same or different.

S305, the electronic device judges whether the first data information comprises a first data index which is the same as the second data index.

The electronic device reads first data corresponding to the second data index from the first data information through the second data index. If the electronic device can read the first data corresponding to the second data index from the first data information through the second data index, the electronic device judges that the first data index identical to the second data index is included in the first data information. If the electronic device does not read the first data corresponding to the second data index from the first data information through the second data index, the electronic device judges that the first data information does not comprise the first data index identical to the second data index.

Note that, the case where the first data information does not include the first data index identical to the second data index includes: one case is that the second data index does not have corresponding first data, i.e., the second data index key does not have corresponding first data value; another case is that the first data corresponding to the second data index is not modified, that is, the first data value corresponding to the second data index is non-user data.

In some embodiments, if the electronic device determines that the first data information includes the first data index identical to the second data index, the electronic device replaces the first data index identical to the second data index in the first data information with a third data index corresponding to the second data index in the configuration file.

The replaced first data information comprises a third data index and first data corresponding to the third data index.

For example, it is assumed that the first data information includes a first data index and first data corresponding to the first data index is: hw_system_right_upgrade_switch=1; the corresponding relation between the second data index and the third data index in the configuration information is as follows: hw_system_light_update_switch, hn_system_light_update_switch; on this basis, since the first data information includes the same first data index as the second data index, that is, the first data index hw_system_light_update_switch in the first data information is the same as the second data index hw_system_light_update_switch in the configuration file, the electronic device replaces the first data index in the first data information with the third data index hn_system_light_update_switch according to the third data index hn_system_light_update_switch corresponding to the second data index in the configuration file. At this time, the first data information includes the third data index and the first data corresponding to the third data index, that is, the first data information includes hn_system_light_update_switch=1.

And when the electronic equipment receives the access request comprising the third data index, the electronic equipment reads corresponding first data from the first data information according to the third data index.

Illustratively, when the electronic device receives an access request including a third data index hn_system_high_update_switch, the electronic device reads the corresponding first data as "1" from the first data information according to the third data index.

In some embodiments, the electronic device traverses each second data index in the configuration file, determining whether the first data information includes the same first data index as the second data index.

The electronic device obtains a second data index, and determines whether the first data information includes a first data index identical to the second data index. If the first data information includes the first data index identical to the second data index, the electronic device re-acquires another second data index, and judges whether the first data information includes the first data index identical to the second data index or not until all the second data indexes in the configuration file are judged.

Correspondingly, the electronic equipment acquires a second data index and judges whether the first data information comprises a first data index identical to the second data index. If the first data information does not include the first data index which is the same as the second data index, the electronic device re-acquires the other second data index, and judges whether the first data information includes the first data index which is the same as the second data index or not until all the second data indexes in the configuration file are judged.

In some embodiments, after the electronic device parses the configuration file, the configuration file includes a correspondence between the second data index, the third data index, and the partition identifier. On the basis, the electronic device can judge whether the first data information comprises the first data index identical to the second data index according to the partition identification included in the configuration file. For example, assuming that the partition identifier is table= "secure", the electronic device may determine whether the first data index identical to the second data index is included in the data partition set_secure.xml according to the partition identifier.

In summary, the electronic device obtains the correspondence between the second data index and the third data index in the configuration file, and when the electronic device determines that the first data index identical to the second data index exists in the first data information, that is, the first data information stores the unmodified data index (i.e., the old key); subsequently, the electronic equipment replaces the first data index which is the same as the second data index according to the third data index which corresponds to the second data index in the configuration file, so that the replaced first data information comprises the third data index (namely a new key) and the first data which corresponds to the third data index; thus, when the electronic device receives the access request including the third data index, the electronic device may read the corresponding first data from the first data information according to the third data index.

Taking into account the first boot after the electronic device is upgraded for the operating system; or when the version information of the electronic device is smaller than the preset version information, the electronic device needs to modify the first data index (i.e. the old key) included in the first data information.

In one implementation, if the electronic device needs to modify the first data index (i.e., the old key) included in the first data information, the electronic device will modify the first data index (i.e., the old key) included in the first data information when the electronic device is first powered on after upgrading the operating system. Based on this, if the electronic device is not first powered on after the operating system is upgraded, that is, the electronic device may have completed modifying the first data index, so the electronic device will not modify the first data index again.

In another implementation, for the electronic device of the new version (i.e., the version information is greater than or equal to the preset version information), the modification of the first data index is already completed when the electronic device is first powered on after leaving the factory. Therefore, if the electronic device is a new version, the electronic device will not modify the first data index again.

Based on this, in some embodiments, as shown in fig. 6, before the electronic device obtains the configuration file, the method further includes:

S3031, the electronic equipment judges whether the electronic equipment is started for the first time after the operation system is upgraded; or the electronic equipment judges whether the version information of the electronic equipment is smaller than the preset version information.

The preset version information may be, for example, an S version, or the preset version information may be, for example, version 6.0. The embodiment of the present application is not limited thereto.

The electronic device may determine whether the electronic device is first powered on after the operating system is upgraded by calling an interface packagermanagerex. The electronic equipment can acquire version information of the electronic equipment when leaving the factory through the ro.product.first_api_level configuration item.

In some embodiments, if the electronic device determines that the electronic device is first powered on after the operating system is upgraded; or the electronic equipment judges that the version information of the electronic equipment is smaller than the preset version information, and the electronic equipment acquires the corresponding relation between the second data index and the third data index in the configuration file, when the electronic equipment judges that the first data index which is the same as the second data index exists in the first data information, namely the first data information stores an unmodified data index (namely an old key); and then, the electronic equipment replaces the first data index which is the same as the second data index according to the third data index which corresponds to the second data index in the configuration file, so that the replaced first data information comprises the third data index (namely a new key) and the first data which corresponds to the third data index.

Correspondingly, if the electronic equipment judges that the electronic equipment is not the first startup after the operation system is upgraded; or the electronic device judges that the version information of the electronic device is larger than or equal to the preset version information, the electronic device does not need to repeatedly modify the first data index included in the first data information, and the power consumption of the electronic device can be effectively reduced.
