Black Screen in `EffectPlayerView` After Successful Initialization (Android / React Native)

[pareshbbi]

I am integrating Banuba React Native SDK using @banuba/react-native.
The SDK initializes successfully, the camera is opened, the player is started, and no errors are emitted — but the camera preview remains black.

All SDK lifecycle calls appear to succeed, and events confirm that the camera and player are running.

---

Expected Behavior

After:

• initialize()
• attachView(nativeTag)
• openCamera()
• startPlayer()

👉 The camera preview should be visible inside EffectPlayerView.

---

Actual Behavior

• EffectPlayerView renders
• SDK initializes successfully
• Camera opens
• Player starts
• Camera facing switch works (no error)
• Screen stays black
• No SDK errors are emitted

Environment

• Platform: Android
• OS: Android 13 / 14 (tested on emulator & real device)
• React Native: 0.79.5
• SDK: @banuba/react-native
• Architecture: New Architecture disabled
• JS Engine: Hermes
• Build Type: Debug
• Device: Physical + Emulator

---

Permissions

Permissions are granted successfully at runtime:

• CAMERA
• RECORD_AUDIO

---

Initialization Code (Simplified Flow)

BanubaSdkManager.initialize([], BANUBA_TOKEN);
BanubaSdkManager.attachView(nativeTag);
BanubaSdkManager.openCamera();
BanubaSdkManager.startPlayer();

The nativeTag is obtained via:

findNodeHandle(ref)

which returns a valid numeric value.

What I Have Already Tried

• Delaying attachView, openCamera, and startPlayer
• Retrying initialization up to 3 times
• Switching camera facing (front/back)
• Testing on multiple devices
• Verifying permissions
• Ensuring SDK initializes before attaching the view
• Verifying token validity (SDK initializes successfully)

---

Questions / Help Needed

1. Is there any required order or missing call for Android preview rendering?
2. Is EffectPlayerView compatible with Fabric / new RN versions?
3. Does Android require an explicit surface lifecycle callback?
4. Is there a known issue with black preview but running camera?
5. Should startPlayer() be called before openCamera() on Android?

---

Reproducibility

✅ 100% reproducible on Android
❌ iOS not tested yet

Additional Notes

• Video recording starts without throwing errors
• No crash or warning in Logcat
• onCameraOpen event fires successfully
• View background remains black (#000)
