Description
I encountered an issue while trying to build my React Native project. The build fails with the following error:

same issue here

[Dennis-Neduvelil]

The Android build fails when adding react-native-vision-camera. This issue can be resolved by updating the code in CameraSession.kt:

File: package/android/src/main/java/com/mrousavy/camera/core/CameraSession.kt

Fix:

93- override fun getLifecycle(): Lifecycle = lifecycleRegistry  
93+ override val lifecycle: Lifecycle  
94+ get() = lifecycleRegistry

Deleting node_modules and reinstalling it fixes it.

The Android build fails when adding react-native-vision-camera. This issue can be resolved by updating the code in CameraSession.kt:

File: package/android/src/main/java/com/mrousavy/camera/core/CameraSession.kt

Fix:

93- override fun getLifecycle(): Lifecycle = lifecycleRegistry  
93+ override val lifecycle: Lifecycle

This Node.js script reads the CameraSession.kt file, replaces the specified line and saves the change. Run it with node script.js from the root of your project.

[Andre-Capelli]

Same issue still happening

[shealan]

Running into the same issue on a new project. Any ideas?

[Marcin-Falkowski]

Try this:

For newests RN versions:

1. Install patch-package and postinstall npm install patch-package postinstall-postinstall
2. Edit files for react-native-vision-camera in node_modules with this commit 6501b63#diff-265d108e616a25a6325b349a2b497d527a1cc2c4a972787cc5ed9c5cd5a91c6b
3. Generate patch npx patch-package react-native-vision-camera

You can also add script to your package.json scripts:

"scripts": {
  "postinstall": "patch-package"
}

@saif482 to use latest version of react-native-vision-camera (v.4.6.3) - update your react native and whole stack.

Ran into the same issue with Expo SDK 54 (React Native 0.81.0). Here is the fix (and patch file):

In node_modules/react-native-vision-camera/android/src/main/java/com/mrousavy/camera/react/CameraViewManager.kt, getExportedCustomDirectEventTypeConstants expects MutableMap<String, Any> but the current code returns Map<String, Any>. Add toMutableMap() at the end to fix it.

  override fun getExportedCustomDirectEventTypeConstants(): MutableMap<String, Any>? {
    return MapBuilder.builder<String, Any>()
      .put(CameraViewReadyEvent.EVENT_NAME, MapBuilder.of("registrationName", "onViewReady"))
      .put(CameraInitializedEvent.EVENT_NAME, MapBuilder.of("registrationName", "onInitialized"))
      .put(CameraStartedEvent.EVENT_NAME, MapBuilder.of("registrationName", "onStarted"))
      .put(CameraStoppedEvent.EVENT_NAME, MapBuilder.of("registrationName", "onStopped"))
      .put(CameraShutterEvent.EVENT_NAME, MapBuilder.of("registrationName", "onShutter"))
      .put(CameraErrorEvent.EVENT_NAME, MapBuilder.of("registrationName", "onError"))
      .put(CameraCodeScannedEvent.EVENT_NAME, MapBuilder.of("registrationName", "onCodeScanned"))
      .put(CameraPreviewStartedEvent.EVENT_NAME, MapBuilder.of("registrationName", "onPreviewStarted"))
      .put(CameraPreviewStoppedEvent.EVENT_NAME, MapBuilder.of("registrationName", "onPreviewStopped"))
      .put(CameraOutputOrientationChangedEvent.EVENT_NAME, MapBuilder.of("registrationName", "onOutputOrientationChanged"))
      .put(CameraPreviewOrientationChangedEvent.EVENT_NAME, MapBuilder.of("registrationName", "onPreviewOrientationChanged"))
      .put(AverageFpsChangedEvent.EVENT_NAME, MapBuilder.of("registrationName", "onAverageFpsChanged"))
      .build()
      .toMutableMap() // <-- convert to MutableMap
  }

In node_modules/react-native-vision-camera/android/src/main/java/com/mrousavy/camera/react/CameraViewModule.kt, canRequestPermission references currentActivity which causes an error. Change it to reactApplicationContext.currentActivity.

  private fun canRequestPermission(permission: String): Boolean {
    val activity = reactApplicationContext.currentActivity as? PermissionAwareActivity
    return activity?.shouldShowRequestPermissionRationale(permission) ?: false
  }

Patch file: react-native-vision-camera+4.7.1.patch

[souhailtourjmen]

I ran into the same problem and fixed it by adding a small postinstall patch script. The script automatically replaces the problematic lines in react-native-vision-camera after yarn install / npm install.

👉 Create a file scripts/patch-vision-camera.js:

const fs = require("fs");
const path = require("path");

const visionCameraPath = path.join(
  __dirname,
  "../node_modules/react-native-vision-camera/android/src/main/java/com/mrousavy/camera"
);

function patchFile(filePath, searchValue, replaceValue) {
  const absolutePath = path.resolve(filePath);

  if (!fs.existsSync(absolutePath)) {
    console.warn(`⚠️ File not found: ${absolutePath}`);
    return;
  }

  let content = fs.readFileSync(absolutePath, "utf8");

  if (content.includes(replaceValue)) {
    console.log(`✅ Already patched: ${filePath}`);
    return;
  }

  if (!content.includes(searchValue)) {
    console.warn(`⚠️ Could not find "${searchValue}" in ${filePath}`);
    return;
  }

  content = content.replace(searchValue, replaceValue);
  fs.writeFileSync(absolutePath, content, "utf8");

  console.log(`🔧 Patched: ${filePath}`);
}

// 1) Patch CameraViewManager.kt
patchFile(
  path.join(visionCameraPath, "react/CameraViewManager.kt"),
  "override fun getExportedCustomDirectEventTypeConstants(): MutableMap<String, Any>? =",
  "override fun getExportedCustomDirectEventTypeConstants(): Map<String, Any>? ="
);

// 2) Patch CameraViewModule.kt
patchFile(
  path.join(visionCameraPath, "react/CameraViewModule.kt"),
  "val activity = currentActivity as? PermissionAwareActivity",
  "val activity = reactApplicationContext.currentActivity as? PermissionAwareActivity"
);

Then add this line to your package.json so it runs automatically:

"scripts": {
  "postinstall": "node scripts/patch-vision-camera.js"
}

[Fed0t]

"postinstall": "node scripts/patch-vision-camera.js"

Thanks!

I believe this is now fixed by https://github.com/mrousavy/react-native-vision-camera/pull/3583 and should be closed 👍
