Proxy Server Instrumentation for Cross-Platform Mobile Web Debugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Debugging mobile web applications across devices with different operating systems is limited, particularly for JavaScript debugging on Android devices, as existing methods are not effective in real-world conditions and are platform-dependent.
Innovation Solution
A cross-platform remote debugging framework that uses a proxy server to fetch and instrument webpages, allowing for debugging independent of the device's operating system, by inserting debugging code and manipulating breakpoints through the proxy server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If native debugging methods are used on mobile devices, then debugging is limited to the specific operating system and browser, but portability and cross-platform debugging capability are lost
Solution Approach 1:
The patent introduces a proxy server as an intermediary between the mobile device and the debugging client. The proxy server fetches webpages, performs instrumentation by inserting debugging code, and forwards the instrumented pages to the device. This mediator enables cross-platform debugging by centralizing the instrumentation logic on the server side, allowing debugging clients on different platforms to connect to the same proxy server and debug the same application uniformly.
2Ease of operation
If debugging code is inserted directly into mobile applications, then debugging can be performed on the device, but the debugging process becomes dependent on the device's operating system and browser
Solution Approach 1:
Instead of inserting debugging code directly into the mobile application on the device (bottom-up approach), the patent inverts the approach by performing instrumentation on the proxy server before the webpage reaches the device (top-down approach). The proxy server intercepts the webpage, injects debugging code into the HTML/JavaScript, and then serves the instrumented page to the mobile browser. This inversion allows the debugging infrastructure to remain platform-agnostic while still enabling easy debugging on the device.
3Reliability
If extensive debugging is implemented during construction, then code quality improves, but many bugs remain undetected until real-world execution
Solution Approach 1:
The patent implements preliminary action by performing instrumentation and preparing the debugging environment before the application is deployed to real-world conditions. The proxy server pre-loads webpages, pre-injects debugging code, and pre-establishes connection channels between the device and debugging client. This preliminary preparation ensures that when the application runs in real-world scenarios, bugs can be detected and debugged immediately without setup delays, thus reducing the time loss between bug occurrence and detection.

AI summary
Disclosed herein are technologies for remote debugging in mobile web applications using a platform-independent debugging proxy server. Particularly, the debugging proxy server acts as an intermediary by fetching and performing instrumentation on a requested webpage by a target browser. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
