🔍 Background

The Viwoods Reader blocks notifications using a hardcoded application whitelist inside the system services code. The check lives in services.jar (specifically classes2.dex) and drops notifications from non-whitelisted apps before they are posted, even when notification permissions are enabled.

Technical Context

• File: /system/framework/services.jar
• DEX: classes2.dex
• Class: com.android.server.notification.NotificationManagerService
• Method: enqueueNotificationInternal()

---

✅ What This Module Does

This Magisk module patches classes2.dex inside services.jar systemlessly to disable the notification whitelist check.

Patch Summary

• Disables the notification whitelist check
• Allows all applications to post notifications
• Applied systemlessly via Magisk
• Fully reversible by removing the module
