…ed README and PROJECT_STATE.
- Added FileOutputHook to intercept Bitmap.compress and FileOutputStream writes - Fixed XSharedPreferences issue by using external storage path (/sdcard/.camerainterceptor/) - Added fallback path detection in HookDispatcher.findInjectableImagePath() - Fixed infinite recursion by reading raw file bytes instead of using Bitmap.compress - Added isLoadingInternalImage flag to prevent hook re-entry - Updated ImagePickerActivity to save to world-readable external storage - Camera.takePicture() hook now successfully delivers injected image
- Add isProfilingEnabled() to HookDispatcher - Create missing list_item_app_mode.xml layout - Add FileOutputStream.write(byte[], int, int) hook for Pattern 2 apps - Improve JPEG detection with isJpegDataAtOffset and isValidJpegStructure - Enhance Logger with debug mode toggle and statistics tracking - Add hook-specific logging methods (logHookTriggered, logInjectionSuccess, logInjectionFailure) - Implement rate limiting for rapid captures (100ms minimum interval) - Add image caching with SoftReference (GC-friendly under memory pressure) - Add max file size check (10MB limit) - Add OOM error handling with cache clearing
- Create MediaStoreHook.java for modern Android 10+ save paths - Hook MediaStore.Images.Media.insertImage(Bitmap) - replaces bitmap parameter - Hook MediaStore.Images.Media.insertImage(Path) - replaces file path parameter - Hook ContentResolver.openFileDescriptor() for scoped storage writes - Hook ContentResolver.openFileDescriptor() with CancellationSignal overload - Register MediaStoreHook in MainHook Estimated coverage improvement: 70% -> 80%
- Add PNG format support to Bitmap.compress hook (JPEG + PNG now intercepted) - Add PNG header detection (89 50 4E 47 magic bytes) - Add isImageData() helper for unified JPEG/PNG detection - Extend isImageFile() to detect .webp, screenshot, capture filenames - Update InterceptingOutputStream for PNG interception - Improve logging to show detected format type Estimated coverage improvement: 80% -> 85%
- CameraHook: Add 2s timeout, only block original capture after confirming valid image data - Camera2Hook: Add comprehensive try-catch, never break app's camera flow - FileOutputHook: Add null checks and graceful fallback for Bitmap.compress - Add GitHub Actions workflow for automatic APK builds on source changes - Update .gitignore for Android projects This prevents app crashes/hangs when injection fails for any reason.
