GROPG: The Revolutionary Graphical Debugger for Mobile Apps

Introducing GROPG, the world's first graphical on-phone app debugger that transforms mobile app development. Developed by a collaboration between Microsoft Research and the University of Texas at Arlington, GROPG enables developers to debug their Android apps directly on their phones with a powerful graphical interface. Key features include attaching a desktop debugger, setting and managing breakpoints, inspecting thread stacks, and visualizing memory values. GROPG significantly reduces the complexity of mobile debugging while enhancing performance and usability, making it an essential tool for developers.

  1. Introducing GROPG, the world’s first graphical on-phone app debugger GROPG: A Graphical On-Phone Debugger Test mobile phone app with a powerful graphical debugger Nikolai Tillmann nikolait@microsoft.com Microsoft Research Redmond, WA 98052 Christoph Csallner csallner@uta.edu Tuan Anh Nguyen, tanguyen@mavs.uta.edu Computer Science and Engineering Department University of Texas at Arlington (3) Text-based on-phone debugger Less powerful than graphical debugger I just finished coding my Android app  Current options: Debug pane handle and transparency slider Control buttons In-scope variables and reachable heap values (2) Attach desktop debugger to a virtual device Cannot emulate all phone features (e.g., GPS) Write to memory Source code with breakpoint GROPG Features (1) Attach desktop debugger to a phone Need two devices;Restricted movement • Load source code files • Set breakpoints • View and edit active breakpoints • Inspect & change in-scope memory values including heap • Step into, over, and out of instructions • Inspect threads and runtime stacks • View current source code location Threads and invocation stacks Observations User interface of debuggee • It is hard to port an existing desktop debugger to mobile phones • Limited screen size on mobile devices • Increasing performance of mobile phones J GROPG Architecture Preliminary results GROPG has a higher memory footprint [MB] but enables faster debugging [min:s]. Desktop-based Android debuggerattached to a phone GROPG needs fewer steps for setting a breakpoint.
