PROFILE
Matthew Lee
Worked on the keymanapp/keyman repository to deliver robust improvements to Android keyboard height management and user experience. Focused on stabilizing keyboard resizing across device orientations, the developer refactored core Java logic, enhanced UI/UX with a grabbable resize bar, and introduced real-time feedback for users. They improved test reliability by bypassing dynamic height in unit tests and maintained clear, up-to-date documentation using Markdown and XML. Through code cleanup, variable management, and cross-module collaboration, the work reduced complexity and improved maintainability. These efforts resulted in more predictable keyboard behavior, faster integration for downstream apps, and a smoother experience for end users.

Dec 1, 2025December 2025 monthly summary for keymanapp/keyman: Delivered a major UX upgrade to the Keyboard Height Adjustment feature, adding a grabbable height bar with real-time percentage feedback, orientation-aware behavior, and simplified instructions to improve usability and accessibility across devices. Implemented UI optimizations by compressing two text boxes into one to save vertical space in the dialog. Added robust touch-height calculation with immediate percentage updates and boundary clamping to prevent odd UI states. Performed extensive code cleanup and refactoring to reduce complexity and improve maintainability, aligning with the Activity-based flow. The work included cross-module collaboration within Android/KMAPro and featured multiple co-authored commits that emphasize quality and teamwork.

Nov 1, 2025In November 2025, delivered a feature focused on keyboard height management improvements and KMManager documentation for the keymanapp/keyman project. Key outcomes include robust orientation handling for keyboard height, refactored height calculation logic, and updated documentation with clearer min/max height naming. These changes improve user experience during orientation changes (including when the keyboard is not loaded) and enhance maintainability through better code clarity and up-to-date docs.

Mar 1, 2025Monthly summary for 2025-03 emphasizing business value and technical accomplishments in the Keyman Android KMManager stack. Focused on stabilizing keyboard height handling, expanding orientation support, improving test reliability, and maintaining clear API/docs for faster integration. Key achievements (top 5): - Android ApplyKeyboardHeight: bug fixes and behavior corrections across edge cases, bracket handling, and input gating; added path to applyKeyboardHeight(context, 0) to enforce safe defaults. - KMManager core engine updates: multiple core engine changes and new variables enabling improved functionality and smoother KMEngine integration. - KMManager Keyboard Height and Orientation Enhancements: introduced overloads for getKeyboardHeight and applyKeyboardHeight for alternate orientations, added default keyboard height, variable cleanup, and finalization of changes. - KMPro AdjustKeyboardHeightActivity enhancements: expanded height-adjust functionality in KMPro to support practical height adjustments. - Documentation and test stability improvements: updated docs for applyKeyboardHeight and overloads, added tests stability by bypassing dynamic height in tests, and introduced KMEngine_PrefsKey as a constant for clarity. Business value and impact: - Increased reliability and predictability of on-screen keyboard sizing across devices and orientations, reducing crash risks and improving user experience. - Faster integration for downstream apps via clearer KMManager APIs and updated docs. - More stable CI/test runs with bypassed dynamic heights, reducing flaky tests and improving release confidence. Technologies/skills demonstrated: - Java/Android KMManager updates, refactoring and variable management. - Cross-module engine updates and KMEngine integration considerations. - Documentation discipline and test stability practices. - Code maintenance and consistency improvements (constants, naming, imports).
