Problems solved by technology
During the iteration of the TV system software, due to the improvement of the system version or the addition of new functions and preset features, the demand for DATA space will increase compared with the old version; More and more data files occupy the DATA partition space
These factors lead to insufficient free space in the DATA partition when the TV is performing an OTA network upgrade, which may cause the OTA upgrade process to fail, or even cause the system to fail to start or operate normally after the OTA upgrade, which seriously affects the use of the TV by users.
[0003] At present, when domestic manufacturers encounter OTA network upgrade failures, they can only use after-sales personnel to flash the phone at the user's home; some manufacturers even no longer provide users with software OTA network upgrade services

Embodiment Construction
[0032] The present invention aims to propose a method for OTA network upgrade of Android smart TV system software, to ensure normal OTA upgrade of system software, and to avoid upgrade failure caused by insufficient DATA available space, which affects the use of TV by users.
[0033] For ease of understanding, at first, the OTA network upgrade process of the existing TV complete set software, the impact of the DATA partition on the upgrade, and the solution to the insufficient capacity of the DATA partition in the present invention are described in detail:
[0034] 1. The OTA network upgrade process of the existing TV complete set software:
[0035] 1) The preset system upgrade application on the TV terminal downloads the OTA upgrade package released by the manufacturer from the server through the network and matches the terminal, and performs signature and integrity verification on the version package, and sets the recovery mode upgrade flag after the check is passed;

The invention belongs to the software upgrade technology and discloses a method for carrying out OTA network upgrade on system software of an Android smart television to guarantee normal upgrade of OTA of the system software and avoid failed upgrade caused by insufficient DATA available space from affecting a user to use the television. The method comprises the following steps of judging whether current DATA partition surplus capacity meets requirements for this upgrade before upgrade, if no, executing cleaning of the space, when a user application is cleaned, carrying out backup on the user application and setting a backup flag, completing first restart after upgrade, and selecting the user application to carry out recovery and installation according to the user need after an Launcher detects the backup flag.
Description
technical field [0001] The patent of the present invention belongs to the software upgrade technology, and in particular relates to a method for OTA (on-the-air) upgrade of Android smart TV system software. Background technique [0002] Android smart TV OTA network upgrade is an effective means for TV manufacturers to continue to bring users new product and special software experience after TV sales. During the iteration of the TV system software, due to the improvement of the system version or the addition of new functions and preset features, the demand for DATA space will increase compared with the old version; More and more data files occupy the DATA partition space. These factors lead to insufficient free space in the DATA partition when the TV is performing an OTA network upgrade, which may cause the OTA upgrade execution process to fail, or even cause the system to fail to start or operate normally after the OTA upgrade, which seriously affects the use of the TV by u...
