What's New in v0.3.0 (Android Mobile)

1. Up to 3.85x Faster Multi-File & Folder Transfers

• Kernel-Level Atomic Finalization (renameat2): Incoming transfers now finalize directly inside Android's FUSE filesystem (/sdcard/Download/Beside) using RENAME_NOREPLACE in < 1 ms, bypassing secondary userland copies.
• Physical Device Benchmark: 50-file folder transfer time dropped from 21.16s (v0.2.0) to 5.50s (74.0% latency reduction).

2. Instant Control Framing (TCP_NODELAY)

• Eliminates 40–200 ms Nagle ACK delay stalls on Wi-Fi chipsets.
• Outgoing Phone-to-PC 10 MB transfers are up to 2.63x faster (11.57s -> 4.40s).

3. Simultaneous Multi-Device Sharing & Custom Device Groups (Beside Pro)

• Concurrent Multi-Peer Streaming: Select multiple paired devices and stream files, folders, or snippets simultaneously over isolated Mutual TLS 1.3 streams.
• Custom Named Device Groups: Create and organize local device groups (device_groups.json) with zero cloud dependencies.
• Resilient Offline Handling: Automatically skips offline group members without stalling and tracks live per-peer delivery progress.

4. Android Ecosystem Integration & MediaStore Indexing

• System Share Sheet: Share photos, videos, documents, or URLs directly from any app into Beside (singleTask launch mode prevents duplicate engines).
• Storage Access Framework (SAF): Pick any custom save directory (Beside Pro), or receive directly into Downloads/Beside (Beside Free).
• Automatic MediaStore Indexing: Transferred photos and videos appear immediately in Google Photos and system galleries.

Key Features & Highlights in v0.2.0

1. Thumb-Friendly 4-Tab Mobile Navigation

Designed for intuitive one-handed mobile ergonomics:

• Home Tab: Device identity card, live network status, nearby peer cards with one-tap pair/send buttons, and quick action shortcuts (Files, Folders, Messages).
• Activity Tab: Chronological transfer history with folder nesting, file size badges, and message log.
• Trusted Devices Tab: Pinned cryptographic device keys with one-tap trust revocation and rapid pairing shortcuts.
• Settings Tab: Device identity configuration, Storage Access Framework (SAF) folder picker, theme preferences, and Pro license status.

2. Deep Android Native System Integrations

• Android System Share Sheet: Share photos, videos, archives, or URLs directly from Google Photos, YouTube, Files, or browsers into Beside's outgoing queue via standard ACTION_SEND and ACTION_SEND_MULTIPLE intents.
• Gallery Auto-Scan (MediaScanner): When photo or video transfers complete, Beside automatically indexes them via MediaScannerConnection. They appear instantly in your camera roll and Google Photos without requiring a device reboot.
• Foreground Service with Persistent Notification: BesideTransferService keeps transfers running at full speed in the background even when you switch apps or turn off the screen.
• Wi-Fi & Wake Locks: Automatically acquires WifiManager.MulticastLock for zero-configuration mDNS discovery, and high-performance Wi-Fi & CPU WakeLocks during streaming to maintain wire speed on aggressive battery-saving OEM roms (MIUI, HyperOS, One UI).
• Storage Access Framework (SAF): Full support for scoped storage on Android 10, 11, 12, 13, and 14, allowing you to save received files directly to custom folders or SD cards.
• Hardware Android Keystore: Private device keys are encrypted at rest with hardware-backed AES-256-GCM (TEE / StrongBox).

3. Light and Dark Theme Support

• Full adaptation to your system theme preference with an instant manual toggle in the Settings tab.

4. Wire-Speed TCP Streaming (Flat 64 KB RAM Consumption)

• Streams files machine-to-machine at full Wi-Fi speeds (up to 110 MB/s).
• Streams in bounded 64 KB memory chunks, completely eliminating out-of-memory crashes on mobile devices.

5. Mutual TLS 1.3 & 8-Digit SAS Pairing

• 8-digit visual SAS code derived from the TLS 1.3 Key Exporter to verify new peers and prevent MITM attacks on untrusted public Wi-Fi.

Installation & Battery Optimization Tips

1. Install Unknown Apps: When downloading the APK for the first time, allow your browser to install unknown apps when prompted.
2. MIUI / HyperOS (Xiaomi / POCO / Redmi): In Settings → Apps → Beside → Battery Saver, select No Restrictions to prevent background transfer interruptions.
3. One UI (Samsung): In Settings → Apps → Beside → Battery, ensure Beside is not set to "Deep Sleeping".
