I think you forgot to remove this code at the bottom of andoird/app/build.gradle

apply from: file("../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesAppBuildGradle(project)

@iwangsyah I had the same problem, and this answer helped me! I think I actually forgot to delete the code in that line 😄

It seems I'm facing a similar issue. I'm unsure why this file is being generated after deletion and why it's necessary to run the app. Additionally, I've noticed that in some React Native projects, this file isn't even present.

I faced the same issue when I migrated my project from React Native version 0.74.x to 0.75.x. I finally resolved it.

I was having the same issue migrating from 0.74.5 to 0.76.5. The solution suggested here fixed the problem, however, the line to be deleted was not at the end of the file, but at line 122 (a few lines before the end).

I successfully solved the problem using the above method, but now it prompts me

Cannot resolve symbol 'SafeAreaContextPackage' Cannot resolve symbol 'RNScreensPackage'

Can anyone provide some help?

Check if your app/build.gradle file has auto link enabled, as in the example below:

react { autolinkLibrariesWithApp() }
