30 seconds. Zero cuts. A first-person sprint where real-time AR UI manipulation is your only shield. ⚡️🖐️ Watch as glowing neon bridges are swiped into existence to reach the "safe zone."
But the false safety twist is brutal—pulling off the smart-visor shatters the beautiful illusion into a toxic wasteland with a massive mechanical predator waiting above. 🕶️💥🦖
Tamper-Proof Content Blocker & Device Protection App
System-Level Mobile Threat Protection & Local Network Filtering
The Challenge
Standard Android content filters are easy for users to bypass, disable, or uninstall, while third-party remote VPNs introduce severe latency and data privacy risks.
The Solution & Impact
Built a Kotlin-native Android application that enforces device-level content filtering and anti-tampering protection locally without sending user traffic to external servers.
Local VPN & DNS Filtering: Intercepts system-wide DNS packets via a local VpnService TUN interface to block prohibited domains locally with zero latency.
System-Level Security Hooks: Utilized Android Accessibility Services and Device Admin APIs to prevent unauthorized uninstallation, force-stopping, or setting bypasses.
Tamper-Proof Lock: Enforced settings locking via an encrypted, randomized password generator to ensure non-bypassable enforcement.
Tech Stack: Kotlin | Android SDK | VpnService | Accessibility APIs | DeviceAdminReceiver | Jetpack Compose
Disclosure screen before requesting Accessibility is exactly what reviewers look for now. Did you run into the Restricted Settings flow on Android 13+, where sideloaded APKs block Accessibility grants outright, or is this shipping through Play only?
