Description
Technical Field
The invention belongs to a software upgrading technology, and particularly relates to a method for performing OTA (over the air on-line) upgrading on Android smart television system software.
Background
The Android smart television OTA network upgrading is an effective means for television manufacturers to continuously bring new-product characteristic software experience to users after television sales. The requirement for DATA space is larger than that of the old version due to the fact that the system version is improved or new function preset features are added in iteration of the whole television system software; during the use of the television, users can generate more and more DATA files to occupy the DATA partition space due to the installation of various applications. These factors may cause the OTA upgrade to be performed by the television, and if the available space of the DATA partition is insufficient, the OTA upgrade may fail to be performed, even the system cannot be started or run normally after the OTA upgrade, which may seriously affect the user to use the television.
At present, when an OTA network fails to be upgraded, domestic manufacturers can only go to the home of a user for on-site updating through after-sales personnel; even some vendors no longer provide software OTA network upgrade services to users. Therefore, the invention provides a very necessary means for detecting whether the available space of DATA supports the software version upgrade in real time during the OTA network upgrade of the television and ensuring that the television of a user can be upgraded normally by OTA by adopting a proper space cleaning strategy when the space is insufficient.

b. executing signature verification again when entering a recovery mode, decompressing an OTA upgrade package to execute an upgrade script file, firstly detecting whether the residual free space capacity of the DATA partition meets the upgrade requirement of the version, if so, continuing the upgrade process, and entering the step d; if not, entering the step c;
c. performing space cleaning on the DATA partition until the remaining free space capacity meets the version upgrading requirement, continuing upgrading, entering the step d, and backing up cleaned user application when performing space cleaning;
d. after upgrading is completed, restarting to enter an Android system, checking and installing updated preset application, and normally starting the system after the system preset application is updated and installed; and then, selecting the user application for restoring the backup according to the user requirement.
As a further optimization, in step a, a DATA partition space detection processing module is added in the upgrade script of the OTA upgrade package, and is used for executing a function of detecting whether the remaining free space capacity of the DATA partition meets the upgrade requirement of the current version.
As a further optimization, the detecting whether the remaining free space capacity of the DATA partition meets the requirement of the version upgrade specifically includes:
1) estimating the occupation condition of the partitioned storage space of the/data after different version packages are installed, recording an old version before upgrading as Sold, recording an upgraded new version as Snew, and calculating the difference when the Snew is larger than the Sold;
2) reserving 10% of space capacity of the DATA partition according to system convention, and recording as Sr;
3) calculating to obtain a new version of DATA partition free space requirement DeltaS (Snew-Sold + Sr);
4) and calculating the free Space of the current DATA Space in real time, wherein if the Space is less than Delta S, the rest free Space cannot meet the requirement of the version upgrading, and if the Space is more than or equal to Delta S, the rest free Space can meet the requirement of the version upgrading.

Detailed Description
The invention aims to provide a method for performing OTA network upgrade on Android smart television system software, which guarantees the OTA normal upgrade of the system software and avoids the problem that the use of a television by a user is influenced due to upgrade failure caused by insufficient DATA available space.
For easy understanding, first, the following detailed descriptions are made of the OTA network upgrade procedure of the whole tv software in the prior art, the influence of the DATA partition on the upgrade, and the solution of the present invention to the DATA partition capacity deficiency:
the OTA network upgrading process of the whole television software in the prior art comprises the following steps:
1) the method comprises the steps that a preset system upgrading application on a television terminal downloads an OTA upgrading packet which is issued by a manufacturer and matched with the terminal from a server through a network, signature and integrity verification are carried out on a version packet, and a recovery mode upgrading mark is set after the version packet passes the verification;
2) executing signature verification again when entering a recovery mode, decompressing an OTA upgrade package, running an upgrade script, and realizing the upgrade processing of the file systems of the partitions such as the system, the data and the like, wherein the upgrade processing comprises each partition file and a system preset application file;
3) then restarting the preset application entering the Android system to check the update and installing the preset application into the DATA partition. And starting to operate the system after each preset application is successfully installed.
The abnormal condition at any stage in the above process may cause the failure of the OTA upgrade of the system software of the whole television, and the serious condition may cause the abnormal use of the television. The DATA partition is also called a user DATA area and is a partition mounting type with readable and writable attributes; the system preset application is installed in the partition, and the user application is also in the partition, and system operation or user setting information and the like are also stored in the partition. Therefore, the partition space is consumed more frequently and the usage is the largest.
Secondly, influence of a DATA partition space in an OTA network upgrading process:
1. effects of DATA partition file system upgrades:
when the DATA partition file system is upgraded in the recovery mode, if the space is insufficient, the file is not copied into the partition, the upgrade process is interrupted, or the upgrade file is lost.
2. The influence of application updating is preset when the system is started for the first time after OTA upgrading:
the preset application file may be placed under system/app and data/app, and when OTA is upgraded, the original preset application may be upgraded to a high version or a new preset application may be added. In recovery, the updating only places the application installation files into the corresponding directories, and the updating for installing the applications is checked in the process that the Android system is started for the first time after OTA updating, and when the available space of DATA is insufficient, the preset applications are failed to be installed or cannot normally run after being installed.
3. Impact of insufficient free space of DATA partition on user applications
The user installed application is under data/app, and the priority of installation is after the preset application. When the system or the preset application cannot be normally installed and operated, the user applications cannot be normally used.
Based on the above, the problems to be solved in the present invention are: judging whether the space capacity of the DATA partition meets the upgrading requirement or not; executing a deletion strategy when the DATA partition space does not meet the requirement; and thirdly, recovering the user application in the first boot after upgrading. In order to solve these several problems, the solution proposed in the present invention is as follows:
thirdly, solving the problem of insufficient capacity of the DATA partition:
1. the automatic detection method for insufficient free space of the DATA partition comprises the following steps:
the different version numbers have different requirements on the DATA space after upgrade installation, and the specific requirements on the free space of the DATA partition when the new version system and the preset application are normally installed are estimated. During the manufacture of the OTA differential upgrade package, the version numbers before and after upgrade are already defined, so that the increment of the idle space requirement of the new version after upgrade compared with the old version before upgrade is estimated. The capacity of the currently available space of the DATA partition on the subscriber's television is calculated in real-time over-the-air (OTA) upgrades, and the status of insufficient space available for the DATA partition is automatically detected and identified as compared to the incremental demand for DATA space for the new version installation that has been estimated.
2. The DATA partition cleaning strategy implementation method comprises the following steps:
1) the DATA space cleaning is realized by adopting a two-stage strategy: preferentially executing a primary partial deletion strategy, and limiting to the application and installation of related directories (/ data/dalvik-cache,/data/data,/data/lib); and when the cleaning space is not in place, executing a secondary all-deletion strategy, only reserving a specified directory and a file list which need to be protected in the/data partition, and deleting the rest.
2) When space is cleaned, the application/data/appdakup/directory installed by a user needs to be backed up; and writing a user application backup mark into the Launcher for use, and starting the installation of the backup application when the OTA is started for the first time after upgrading.
3. The application installation of the system starting for the first time after the OTA upgrade is realized:
1) when the system is started for the first time after OTA upgrading, the system firstly checks and installs the preset application, and the system is normally started after the system preset application is updated and installed;
2) and detecting a backup mark of the user application in the launcher application, and starting a boot guide to prompt the user to reinstall the standby application to finish the installation processing of the backup application when the backup mark exists. And when the user finishes processing all backup applications and exits, the application backup marks and the backed-up application installation files are removed. The system will not repeat the installation process of the standby application when starting up subsequently.
The scheme of the invention is further described by combining the drawings and the embodiment:
as shown in fig. 1, the method for performing OTA network upgrade on Android smart television system software in the embodiment includes the following implementation steps:
firstly, when an OTA upgrade package is manufactured at a server side, a DATA partition space detection processing module is added in an upgrade script and used for executing a function of detecting whether the remaining free space capacity of a DATA partition meets the upgrade requirement of the version. And after the upgrading package is manufactured, deploying the OTA upgrading package.
Then, the television downloads an OTA upgrade package matched with the terminal from the network, carries out signature and integrity verification on the version package, and sets a recovery mode upgrade flag after the version package passes the verification; executing signature verification again when entering a recovery mode, decompressing an OTA upgrade package, running an upgrade script, and detecting whether the residual free space capacity of the current DATA partition meets the upgrade requirement or not by a DATA partition space detection processing module in the upgrade script;
if yes, continuing upgrading until the OTA upgrading is finished;
if not, performing space cleaning on the DATA partition, continuing to perform upgrading processing until the remaining free space capacity meets the version upgrading requirement, and when performing space cleaning, backing up the cleaned user application and adding a user application backup identifier to the Launcher for use;
after upgrading is completed, restarting to enter an Android system, checking and installing updated preset application, and normally starting the system after the system preset application is updated and installed; and then, the launcher starts the detection of the user application backup mark, if the user application backup mark exists, the user application of the backup is selected to be restored according to the user requirement, and if the user application backup mark does not exist, the processing is carried out according to the existing flow.
The detecting whether the remaining free space capacity of the DATA partition meets the version upgrading requirement specifically includes:
1) estimating the occupation condition of the partitioned storage space of the/data after different version packages are installed, recording an old version before upgrading as Sold, recording an upgraded new version as Snew, and calculating the difference when the Snew is larger than the Sold;
2) reserving 10% of space capacity of the DATA partition according to system convention, and recording as Sr;
3) calculating to obtain a new version of DATA partition free space requirement DeltaS (Snew-Sold + Sr);
4) and calculating the free Space of the current DATA Space in real time, wherein if the Space is less than Delta S, the rest free Space cannot meet the requirement of the version upgrading, and if the Space is more than or equal to Delta S, the rest free Space can meet the requirement of the version upgrading.
Fig. 2 illustrates the implementation of the deletion cleaning policy and the backup processing flow of the user application installation file when the DATA partition space is insufficient, which includes:
1) firstly, a first-stage partial deletion strategy is executed, and directories (/ data/dalvik-cache,/data/data,/data/lib) are cleared;
2) recalculating DATA partition available Space size, Space', comparing with DeltaS:
space' > DeltaS: backing up the user application, exiting cleaning and continuing upgrading;
otherwise, continuing the next step;
3) executing a secondary all deletion strategy, only reserving a specified directory and a file list which need to be protected in the/data partition, and deleting the rest;
4) and (3) installing an application under the backup/data/app/directory by a user, setting an application backup mark, and continuing the original upgrading process flow after exiting the cleaning flow.
Fig. 3 illustrates the first system start and backup application installation after OTA upgrade, when the system starts, the main scene detects the backup application flag, when the system starts, the boot guide is started to execute the re-selective installation processing of the user application, and after the processing is completed, the backup directory and the backup flag are deleted, which specifically includes:
1) in a first starting system after normal OTA upgrading, except for checking and installing system preset application, detection processing of a backup application mark is added in a main scene, when the mark exists, a starting guide is started, and a selective installation interface of the backup application is popped up.
2) Displaying an application list on a backed-up user application installation interface and providing installation check items, when a user selects an application to be installed, estimating the available capacity of the current DATA space in real time based on the size of an installation file, and prompting the user when the available capacity is insufficient; the user can conveniently select the installation of common applications, and unused or unimportant user applications can abandon the installation.
