## Description

KeyEvent Display is a powerful Android application designed to help users and developers debug and verify the keycodes of physical device buttons. Originally created to troubleshoot hard button functionality on Chinese tablets with similar hardware, it captures and displays key events such as KeyUp, KeyDown, KeyLongPress, and KeyMultiple as Android interprets them.

The app also monitors relevant messages from LogCat and kernel logs, filtered for key-related keywords, offering comprehensive insight into button behavior. While kernel logging requires root access, the tool remains user-friendly with options to toggle the information displayed. It's an ad-free, open-source utility perfect for developers or enthusiasts seeking to debug hardware buttons, export logs, and validate device key events efficiently.
