🌟 What's New in v1.1.0

1. APK Size Optimization & ABI Splitting

  • >62% File Size Reduction: Implemented --split-per-abi Android packaging, shrinking the modern phone target (arm64-v8a) down to 25.0 MB and legacy 32-bit (armeabi-v7a) down to 20.9 MB.
  • R8 Minification & Resource Shrinking: Enabled isMinifyEnabled = true and isShrinkResources = true with targeted ProGuard rules (-keep class io.github.codebyarnob.nexora.** { *; }) preserving FFI, SQLite, and ML Kit models.
  • Font Tree-Shaking: Stripped 99.3% of unused Material icon glyphs, reducing font assets from 1.64 MB to 11.7 KB.
  • Pure Android Native SQLite: Native libsqliteX.so removed in favor of Android framework OS SQLite, saving 1.2 MB per ABI.

2. Large File Transfer Initiation Latency Redesign

  • Lightweight Manifest Negotiation: Senders transmit an immediate, lightweight TransferOffer containing only metadata (session ID, file count, sizes, MIME types, parameters) upon TCP connection.
  • Sub-Second Confirmation Popup: Receivers validate permissions and display the incoming transfer prompt within 18–31 ms for 2 GB+ files (well under the 1,000 ms SLA).
  • Streaming On-the-Fly SHA-256: Pre-transfer whole-file hashing eliminated; files are hashed in parallel with network streaming chunks with constant 512 KB RAM and zero post-transfer verification lag.

3. Production Transfer Completion Protocol

  • Reliable Two-Way Completion Handshake: Replaced unilateral stream closing with an explicit TransferComplete ↔ TransferCompleteAck wire handshake.
  • Immediate Live-Transfer Demotion: Senders and receivers instantly transition state from transferring to completed, stop real-time speed counters, dismiss active Cancel/Pause buttons, and persist verified metrics into SQLite transfer history.

4. Native Camera QR Code Scanner

  • Google ML Kit Integration: Deployed native CameraX barcode scanning engine with 60 FPS viewport processing and sub-100ms QR decode latency.
  • Full-Screen Scanning Interface: Branded cyber-frame overlay, animated neon laser sweep, hardware torch flashlight toggle, gallery QR image picker, and manual IP fallback.

5. 6-State Device Discovery Engine

  • Complete Discovery State Machine: Initial, Scanning, Devices Found, No Devices Found, Permission Required, and Error states.
  • Safe Cryptographic Fingerprint Verification: Mathematical truncation safety prevents RangeError on peer devices.
