🛡️ Advanced Device Verification System — Lock Keys to ID & Expiry Date 💻 | By DPMods

In this exclusive tutorial, I am releasing the **Ultimate Device Verification System** for Android! If you want to sell **Paid VIP Keys** and prevent users from sharing them, this is the system you need. 💎💸

I will show you how to build a secure dialog that locks a key to a specific **Device ID (HWID)** and includes an automatic **Expiry Date**. If the key is used on another phone or the date has passed, access is denied immediately! 🚫📲

✨ Features You'll Get in This System:

• 🔐 Secure Device Verification (HWID) – Mathematically binds the key to one specific device. Even if shared, it won't work on other phones!
• 📅 Automatic Key Expiry – Set a specific expiration date (e.g., 2025). The app auto-checks time and blocks access if expired.
• 🚫 "Key Expired" Logic – Displays a custom dialog with the expiration date when a user tries to use an old key.
• 💰 Paid VIP Protection – Designed specifically for developers selling monthly or lifetime keys.
• 📞 Admin Contact Button – Direct "Admin" button in the dialog so users can message you to buy or renew keys.
• 🎨 Premium Red UI – A bold, high-contrast Red & Black theme with optimized input fields.
• 🛠️ MT Manager Implementation – Complete guide to adding this security using only Smali and XML editing.
