1 Chronological Breakdown of Today's Work

Server Toolchain Verification & ARM64 Environment Fix Identified that the Linux server is headless ARM64 (aarch64) with OpenJDK 17 and Android SDK 36. Resolved the 32-bit x86/x86_64 AAPT2 execution compatibility via qemu-binfmt and symlinked the toolchain to /home/waheed/Android/Sdk.

Dual-App VoIP Architecture Built (Main & Companion Engine) Extracted and structured the two complementary apps at /home/waheed/WhatsappRecorder/VoipCallRecorder/:
• VoipCallRecorder-Main: User library, Material 3 UI, in-app audio player, Room DB, floating in-call badge.
• VoipCallRecorder-Helper: Headless background engine, WhatsApp Accessibility window hooks, mic capture, speakerphone routing, and IPC file relay.

Package Name Refactoring to com.puliyal.* Refactored the entire codebase, directory structures, and configurations from com.whatsappcalls.* to:
• Main App: com.puliyal.voiprecorder
• Companion Helper: com.puliyal.voiprecorder.helper
Updated all build.gradle.kts, AndroidManifest.xml, IPC intent broadcast filters, and FileProvider authorities.

Firebase & Crashlytics Multi-Client Integration Ingested Firebase configuration from /home/waheed/Shazana/uploads/google-services.json (Project: whatsapp-puliyal-rec). Constructed unified multi-client configurations for both package IDs, integrated the Google Services Gradle plugin (4.4.2) and Firebase Crashlytics plugin (3.0.2), added Firebase BoM 33.5.1, and enabled crash telemetry in both Application classes.

Release Keystore Generation & Cryptographic Signing Generated an RSA 2048-bit release keystore valid through 2054. Signed both release APKs with Android Signature Schemes v2 + v3 via apksigner and verified 4-byte byte alignment via zipalign.

Web Portal Publishing & Live Downloads Setup Created VoipCallRecorder.html matching the whatsapp.puliyal.com theme, configured bidirectional navigation with index.html, deployed signed Release and Debug APKs to /home/waheed/whatsapp-site/downloads/, computed SHA-256 hashes, and verified HTTP/2 200 delivery over Nginx.

6 Tomorrow's Action Plan & Physical Device Test Checklist

When resuming tomorrow, follow this structured physical testing protocol:

Device Download & Sideloading Open https://whatsapp.puliyal.com/VoipCallRecorder.html on your Android device (Android 10 through 15) and download:
1. VoipCallRecorder-1.0.0.apk (Main App)
2. VoipCallRecorder-Helper-1.0.0.apk (Companion Helper)

Helper App Permissions Setup (Crucial 3 Steps) 1. Unlock Restricted Settings: Phone Settings → Apps → VoIP Recorder Helper → top-right 3 dots (⋮) → tap "Allow restricted settings" (authenticate with PIN/Fingerprint).
2. Enable Accessibility: Phone Settings → Accessibility → Downloaded Apps → VoIP Recorder Helper Service → Turn ON.
3. Microphone & Battery: Open VoIP Recorder Helper app → Tap "Grant Audio Permission" → Tap "Disable Battery Optimization" (Unrestricted).

Main App Floating Overlay Setup Open VoIP Call Recorder (Main App) → Tap "Enable Floating In-Call Widget" → Grant "Display over other apps" permission.

WhatsApp Call Trigger Test Make or receive a live WhatsApp or WhatsApp Business voice call:
• Verify the floating green "● REC · VoIP Engine Active" badge appears over the calling window.
• Verify the notification shade displays the ongoing recording status.
• Hang up the call and check that the recording file is transferred via IPC to the Main App.
• Open Main App → tap the recording → verify playback and audio clarity.

Verify Firebase Crashlytics Dashboard Open the Firebase Console for project whatsapp-puliyal-rec → Check Crashlytics and Analytics stream to confirm real-time heartbeat and app session telemetry.

Status: All artifacts, codes, configurations, binaries, and web dossiers are synchronized and committed. Everything is ready to resume tomorrow peacefully!
