beemdevelopment/Aegis ? reverse-engineered prompt

Build me an Android authenticator app like Aegis that helps people manage their 2 step verification codes in one secure place.

I want the app to support both TOTP and HOTP, let users add accounts by scanning a QR code, importing from other authenticator apps, or entering details manually. It should keep everything in an encrypted vault, unlock with a password or fingerprint, and prevent screen capture for extra safety. Users should be able to search, sort, group entries, edit them, and tap to reveal codes when needed.

Please also include backup and restore, export options for both plain text and encrypted files, and support for light, dark, and AMOLED themes. Make the design clean and easy to use, with icons for entries and a simple setup flow. If you need current Android guidance or docs, look them up online.
