NoDPI4Android v2.0

[GVCoder09]

🚀 NoDPI4Android 2.0

The first stable release of the 2.x line — and a complete rewrite once again. The app is now native: Kotlin, Jetpack Compose and Material 3 Expressive instead of Python and Kivy. The APK went from 46.7 MB down to 1.8 MB, and the traffic engine now works exactly like the desktop NoDPI.

---

⚠️ Version 2.0 is signed with a new key, so it cannot be installed over v1.0 or v2.0-beta.
Before installing, write down or take a screenshot of your blacklist, then uninstall the old version. Otherwise Android will show "App not installed: package conflicts with an existing package".
After this one-time reinstall, future versions will update normally.

✨ What's New

Native App

• Rewritten from scratch in Kotlin with Jetpack Compose and Material 3 Expressive
• 25× smaller APK, faster start, lower battery usage
• Proper foreground service: the proxy keeps running when the app is closed
• Notification with live traffic stats and a Stop button
• Quick Settings tile to toggle the proxy from the notification shade
• Start on boot (was missing in 2.0-beta)

Traffic Engine — same as desktop NoDPI

• SNI fragmentation — ClientHello is split into TLS records around the SNI field, the SNI itself character by character
• Disorder (on by default) — the first fragment is sent with TTL=1, so DPI sees the stream out of order and lets the connection through. Can be turned off in Settings
• Random fragmentation has been removed, as in the desktop version
• Cloudflare-aware — sites hosted on Cloudflare are sent without fragmentation: it cannot unblock them there and only breaks access. The All mode no longer breaks Cloudflare sites
• Blacklist modes Standard / All / Auto and matching modes Strict / Loose are kept

Statistics & Log

• Home screen shows connections (total / unblocked / direct / errors), traffic and current/average speed
• New Log tab: every connection with traffic, filters, sharing, and one-tap "Add to blacklist"

Blacklist

• Search, add several domains at once, undo deletion
• Import from and export to a text file, reset to default

Settings

• Local network access (0.0.0.0) to share the proxy with other devices, e.g. via hotspot
• Optional proxy authentication (Basic)
• Light / Dark / System theme, new light blue palette, optional dynamic color
• English and Russian, following the system language or chosen manually
• Battery optimization and notification status right in Settings
• First launch offers to disable battery optimization and enable start on boot

Other

• Built-in update check in About
• New adaptive icon

⚠️ Known Issues & Limitations

• Blocked sites hosted on Cloudflare cannot be unblocked by fragmentation
• Telegram, WhatsApp, and voice/video in Discord are not unblocked; sites blocked by IP address are unavailable too
• Android applies a manual proxy only to Wi-Fi networks; on mobile data use an app or browser that supports HTTP proxies
• The blacklist from previous versions cannot be transferred automatically because of the new signing key
