darknethaxor/DH-HackBar ? reverse-engineered prompt

Build me an Android app called DH HackBar for ethical web penetration testing and learning.

It should feel like a handy all in one security toolkit, with a clean interface for generating and managing SQL injection payloads, DIOS queries, bypass helpers, and common web testing utilities. I want features for union based, error based, string based, XPath, MsSQL, PostgreSQL, LFI, RFI, RCE, XSS, and WAF bypass helpers, plus a replacement tool that can convert text to hex, URL encode, Base64, binary, and ASCII both ways.

Please also include useful tools like admin panel finder and scanner, find in page, tamper style request header editing, reverse IP, subdomain checker, hash decrypter, SQL injection scanner, and a place where I can save custom queries. Add an update checker that can pull the latest version, and make it work well on Android 5 and up if possible. Keep the UI simple, fast, and practical, and look up current Android docs online if you need to.
