System application upgrading system based on Android framework

Abstract

The invention provides a system application upgrading system based on an Android framework. The system comprises a Sota cloud server, a Sota APP module and a Sota framework module. The Sota cloud server generates an upgrading strategy; the Sota APP module collects version information of a terminal system, performs data interaction with the Sota cloud server, executes the upgrading strategy issued by the Sota cloud server and downloads an APP needing to be upgraded; after downloading is completed and before updating is completed, the Sota APP module performs file integrity verification and signature verification; a configuration file is generated and is analyzed and processed by the Sota framework module when the system is restarted; the Sota APP module detects the upgrading state of the batch APPs every time the Sota APP module is started, pops up prompt information to a user and uploads log information to the Sota cloud server; and the Sota framework module executes a batch APP upgrading process, sets a corresponding upgrading result state and performs log recording on the upgrading process.

Description

technical field [0001] The invention relates to a vehicle-mounted operating system, in particular to a vehicle-mounted upgrade system. Background technique [0002] The vehicle-mounted Android (Android) system has become a highly customized system after the manufacturer's custom tailoring and adding software and hardware functional modules. The native Android (Android) system public interface (API) can no longer meet the needs of function development, so Each manufacturer will add new interfaces to meet the functional requirements of upper-layer APP development. Therefore, the APP developed based on this system is closely related to the underlying system, and the APPs are also related to each other. When a certain functional module is modified, all other related APPs may need to be modified. This requires a This mechanism can perform batch upgrade and rollback functions of associated APPs. In addition, after the APP development is completed, various program errors (bugs) w...

AI Technical Summary

Problems solved by technology

[0008] 1. It cannot be updated for all types of APPs. For example, APPs with the persist attribute are not allowed to install updates

[0009] 2. The uninstallation and installation of the APK is carried out when the system is running. If the APP is running, the installation process must be killed before the installation can continue, which is prone to abnormal crashes of the APP;

[0010] 3. After the APP is updated, the system may have to be restarted to use the latest version of the APP

[0011] 4. The APP installation process follows the standard installation interface, and the operation is time-consuming

[0012] 5. Before installing the update, you need to copy and backup an old version of the APK to roll back the old version after the installation fails, which will consume additional disk space
