Multiple files for cameraview while build app for android react native

1.6k views Asked by At

I am using react-native-camera and expo-camera in my project. Along with this I am using few firebase features as well.

App is working fine for iOS but not for Android.

After removing firebase classes, I am able to run the app properly in simulator. While creating apk, I am getting following error.

I have to exclude this group from react-native-camera, but I have used latest react-native version. So, it is using auto linking and it's not implemented in build.gradle.

Had to replace react-native-camera with expo-camera. Now everything is working fine.

Add these lines in android/app/build.gradle after Firebase dependencies:

implementation (project(':react-native-camera')) {
  exclude group: "com.google.android.cameraview"
}
