v1.5.5

What's New in v1.5.5

1. SHA-256 Package Integrity Verification

• Automated Checksum Verification: Automatically computes and verifies SHA-256 file hashes on downloaded update APKs before launching the installer, preventing corrupted downloads or payload tampering.
• Visual Verification State: Displays a dedicated Verifying APK integrity... status before handing off to the Android Package Manager.

2. Pre-Download Permission Gating

• Dynamic Permission Check: Evaluates canInstallPackages() dynamically inside the update dialog. Non-Shizuku users are prompted to enable "Install Unknown Apps" before initiating downloads, eliminating redundant downloads.

3. Local-Only Uncaught Crash Diagnostics

• Zero-Telemetry Exception Handler: Automatically intercepts uncaught runtime crashes and saves formatted stack traces locally to device storage (100% offline & private).
• About Screen Diagnostics Card: Displays a red "Recent Crash Log Detected" card with 1-tap Share Log (via native Android share sheet) and Clear Log options.

4. IPC & System Architecture Hardening

• HTTP Connection Cleanup: Enclosed all updater network calls in try/finally blocks to explicitly close HttpURLConnection sockets and prevent battery drain on cellular radios.
• Immediate Download Cancellation: Registered job cancellation hooks to disconnect sockets instantly when a download is cancelled, deleting partial files and returning the UI state to Idle.
• Shizuku Reconnect Safety: Explicitly clears IPC runner references in binderDeadListener to guarantee clean state recovery if the Shizuku daemon dies.
• Ping Process Zombie Fix: Wrapped child ping process execution in try/finally { process.destroy() } to prevent hung child processes on network timeout.
• FPS Polling Memory Cleanup: Hoisted Regex patterns into companion constants, eliminating per-second object allocations in the FPS polling loop.
