    add = > include ‘:@react-native-firebase_app’ project(‘:@react-native-firebase_app’).projectDir = new File(rootProject.projectDir, ‘../node_modules/@react-native-firebase/app/android’) in settings.gradle dont work for me. Did you do anything different besides that?

    my firebase versions:

    "@react-native-firebase/analytics": "17.5.0",
"@react-native-firebase/app": "17.5.0",
"@react-native-firebase/auth": "17.5.0",
"@react-native-firebase/firestore": "17.5.0",

    The error:

    > FAILURE: Build failed with an exception.

    I have same issue occurred in my react native firebase project. I have fixed the issue by changing in android/app/build.gradle file.

    Note : versions for Firebase SDKs are chosen automatically by the BoM, so just remove or modify if any firebase dependency ends with specific version or :+

    In my case, I am not using firebase analytics in my app but it still implemented in gradle file. So, I have comment 1 firebase dependency com.google.firebase:firebase-analytics:+ and my issue resolved.

    Don’t forget to remove node_modules and clean Android build folder before rebuild. Thanks 😊👍.
