Key Mapper is an advanced input customization tool that remaps physical device buttons, gamepads, keyboards, and fingerprint sensors to execute over 100 specific actions. By utilizing Shizuku, it bypasses standard restrictions to run complex macros, screen taps, and broadcast system intents natively.
Technical Overview
Key Mapper intercepts hardware-level Android key events to bind custom commands to device triggers, connected peripherals, or floating on-screen layouts. By leveraging Shizuku and ADB permissions, the app injects macro inputs, monitors lockscreen or media states for constraint mapping, and directly transmits system intents without requiring a rooted environment.
Core Features of Key Mapper
- Comprehensive Hardware Support: Remaps volume buttons, side keys, external gamepads, keyboards, mouse buttons, and fingerprint sensors.
- Advanced Macro Actions: Combines over 100 distinct operations including screen taps, gesture injection, app launching, and direct intent broadcasting.
- Custom Trigger Configurations: Executes mapped commands through long presses, double clicks, sequential presses, or simultaneous multi-key combinations.
- Situational Execution Constraints: Restricts key maps to run only within specific apps, during media playback, or directly on the lockscreen.
