Release Notes - NewBlackbox

Version: Latest Build (2026-01-31)

Bug Fixes

Android 10 Black Screen Fix

Problem: Apps would show a black screen and timeout on Android 10 (API 29) due to initialization failures.

Root Cause:

• BRAttributionSource.getRealClass() returns null on Android < 31 (AttributionSource was added in Android S)
• SystemProviderStub.invoke() crashed calling .getName() on null class
• ClassInvocationStub.injectHook() crashed when getWho() returned null for non-existent services

Solution:

• Added null checks in SystemProviderStub.java before accessing BRAttributionSource.getRealClass()
• Added null check in ClassInvocationStub.java to skip hooks when services don't exist

Files Changed:

• Bcore/src/main/java/top/niunaijun/blackbox/fake/service/context/providers/SystemProviderStub.java
• Bcore/src/main/java/top/niunaijun/blackbox/fake/hook/ClassInvocationStub.java

Removed Features

Xposed Framework Support Removed

• Removed Xposed enablement flags in BlackBoxCore and ClientConfiguration
• Cleaned up AppSystemEnv and repositories to remove Xposed package checks

🔧 Stability Improvements

Anti-Detection Native Hook Stability

Problem: Native file system hooks caused crashes due to infinite recursion.

Solution:

• Removed LOGD calls from critical native hooks (my_fopen, my_open, my_stat, etc.)
• Fixed syntax errors in hook implementations
• Hooks now silently return ENOENT for blocked paths
