Minimalistic Android App - UI Upgrade -- 2

I'm looking to hire a freelance Android developer for a quick task to update my QRNG generator mobile app. Most of the codebase required to implement the functionality is already provided. You will need to make necessary adjustments and enhancements to the existing code to align it with the updated requirements and ensure its compatibility with the latest Android standards. Requirements: 1) Textbox Input: Include a textbox for users to enter the size and filename. 2) Byte Stream Generation: Generate a byte stream from /dev/qrandom based on the entered size. 3) Display Byte Stream: Upon clicking the 'Generate' button, display the byte stream in a scrollable textbox below the button. The display should format the bytes in lines across the screen, removing any null characters. 4) File Writing: Save the byte stream to a file in the /sdcard/ directory, ensuring compliance with the permission requirements of the latest Android version (version 13). 5) App Icon Design: Design a new app icon that adopts a contemporary, minimalistic style. Dashboard Redesign: Revise the dashboard layout to enhance its simplicity and user-friendliness, with a focus on maintaining a professional look. 6) Prompt Completion: Ensure that the redesign is completed promptly. Additional Note: For testing on non-Samsung Quantum phones, adjust the device file from /dev/qrandom to /dev/random. The ideal candidate will have: Proven experience in Android app development 1) Android Development Proficiency: Expertise in Android app development, well-versed in Android SDK and lifecycle management. 2) Programming Languages: Proficiency in Java and Kotlin, capable of adapting and enhancing existing codebases. 3) UI/UX Design: Strong skills in designing intuitive, user-friendly, and minimalistic user interfaces. Ability to conceptualize and implement modern design aesthetics for both the application interface and icon design. 4) Graphic Design: Experience in graphic design, specifically in creating visually appealing and contemporary app icons that align with brand identity. 5) Security and Permissions: Knowledgeable about Android security protocols, particularly in managing filesystem access and permissions as per Android version 13 requirements. 6) Device Compatibility: Familiarity with device-specific features, such as handling special device files (/dev/qrandom, /dev/random) and ensuring cross-device compatibility. This project is intended to be a fast turnaround to refine the app’s usability and aesthetic to ensure it is both professional and intuitive.
