Reproduction for sentry-java#4400

[romtsn]

Summary

Reproduces the issue where CameraX PreviewView content may not be properly masked in Sentry Session Replay.

• Issue: Session Replay is unable to mask content when using the Camera sentry-java#4400
• Uses CameraX 1.3.4 with PreviewView to display camera feed
• Sentry Android SDK 8.11.1 with Session Replay enabled
• Includes buttons to trigger errors while camera is active

Test Instructions

1. Set your Sentry DSN: export SENTRY_DSN="your-dsn-here"
2. Build and install: ./gradlew installDebug
3. Run on a physical device and grant camera permission
4. Tap "Capture Error" or "Trigger Fatal Crash" while camera is showing
5. Check Sentry replay to see if camera content is masked

Expected vs Actual

• Expected: Camera preview should be masked/blacked out in replay
• Actual (reported): Camera content may be visible in replay

Environment variable retrieval won't work on Android

High Severity

System.getenv("SENTRY_DSN") will always return null on Android devices because apps run in isolated processes that don't inherit the build machine's shell environment. The README instructs users to export SENTRY_DSN=... before building, but this env var won't be accessible at runtime. The DSN will always be empty, preventing Sentry from capturing any replays and rendering this reproduction project non-functional.

Unused cameraExecutor creates unnecessary thread pool

Low Severity

The cameraExecutor is declared and initialized as a single-thread executor but is never actually used. The camera provider listener at line 111 uses ContextCompat.getMainExecutor(this) instead. This results in an unnecessary thread pool allocation that only gets shut down in onDestroy().

Unhandled exception from camera provider initialization

Low Severity

The cameraProviderFuture.get() call is outside the try-catch block that handles camera errors. If ProcessCameraProvider initialization fails (e.g., on emulators, devices with camera issues, or unusual configurations), this throws an uncaught ExecutionException that crashes the app without being logged to Sentry. The try-catch only covers unbindAll() and bindToLifecycle(), missing this earlier failure point.
