Android Selection Case Converter

This project implements an Android application that enables users to convert selected text to uppercase or random chaotic case format without requiring special permissions or network access. By registering activities for the ACTION_PROCESS_TEXT intent, the application integrates directly into the native Android text-selection menu, allowing for in-place text replacement within editable fields or copying to the clipboard for read-only sources.

Built using Java, the application maintains a minimal footprint and operates entirely on-device. It serves as a practical tool for users who require quick text formatting during daily tasks and demonstrates how to leverage Android intent filters to extend system functionality without the need for a traditional user interface or background services.
