Smart POS App Update Flow for Silent Installation Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart POS devices require user intervention for mobile management application updates, leading to loss of control and management during the update process, which is inconvenient and disrupts service continuity.
Innovation Solution
A method and apparatus for silently installing and updating the mobile management application on a smart POS device using a backend server and a system interface, allowing updates without device restarts, ensuring continuous control and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile management application is updated through traditional installation methods, then the application can be updated, but the update process requires user intervention and device restart, causing loss of control and service interruption
Solution Approach 1:
The system performs preliminary actions by killing the old application process before the new application is fully installed and activated. This ensures that the update process can proceed without interference from the running old version, while maintaining service continuity through the background installation mechanism.
Solution Approach 2:
The system introduces an intermediary mechanism (the system interface application) that mediates between the update package and the application installation process. This intermediary handles the installation in the background, coordinates process termination, and manages the transition without requiring direct user intervention.
2Ease of manufacture
If the mobile management application is updated by stopping relevant services and processes, then the update can be installed, but the device cannot be managed during this period and user control is lost
Solution Approach 1:
The system implements self-service by automatically killing the old application process and managing the installation sequence without requiring user intervention. The system interface application autonomously handles process termination, installation execution, and service restoration, maintaining device controllability throughout the update process.
3Reliability
If the application update requires device restart, then the update can be applied, but service continuity is interrupted and management is disrupted
Solution Approach 1:
The system maintains continuity of useful action by performing the application update in the background without interrupting device operation. The installation process runs concurrently with device services, and the old application process is terminated in a controlled manner that allows seamless transition to the new version without device restart.
Solution Approach 2:
The system performs preliminary actions by pre-killing the old application process before the new application becomes active. This preliminary process termination prevents conflicts during the transition and enables the new application to start smoothly without requiring a full device restart, thus maintaining service continuity.

AI summary
The present disclosure discloses are an implementation method and apparatus for an application installation on a smart Point of Sale device. The method includes: starting, by an application providing a system interface, an installation service for the mobile management application when judging that a mobile management application update package path received in a broadcast is not empty. According to the saved mobile management application update package, it starts to silently install a new version of the mobile management application. If the installation is successful, the mobile management application update package is changed to the mobile management application successful update file, and the new version of the mobile management application is started. If the installation fails, the mobile management application update package is changed to the mobile management application update failure file, and the old version of the mobile management application is started.
