Answer 1

Based on your questions you can do 3 things here:

1. You can try clearing the Gradle cache by running the following command in the terminal:

./gradlew cleanBuildCache

2. If clearing the Gradle cache does not work, try updating Gradle to the latest version.

./gradlew wrapper --gradle-version 8.0.2

3. You can try increasing the stack size by adding the following line to your gradle.properties file:

org.gradle.jvmargs=-Xss512m

This will increase the stack size to 512MB.

Let me know if it works now. I also would make sure your internet connection is stable.

Having a similar issue. What I noticed, in the node_modules/react-native/android/ there is no aar and just a readme file saying this:

Starting from React Native 0.71, we're not shipping the /android folder inside the React Native NPM package anymore due to sizing constraints on NPM. The Android artifacts are distributed via Maven Central. You can read more about it in this RFC: https://github.com/react-native-community/discussions-and-proposals/pull/508

If you're a library author and you're manipulating the React Native .aar files, to extract headers, extract .so files or do anything with it, you're probably doing something wrong. React Native 0.71 ships with all the necessary logic to let you consume it transparently by just using:

implementation("com.facebook.react:react-android") 
// or to keep
backward compatibility with older versions of React Native:
implementation("com.facebook.react:react-native:+") 

You should consider refactoring your library code not to unzip/manipulate the React Native .aar files.

This README.md file is kept in this folder as some libraries are checking the existence of the /android folder and failing user builds if the folder is missing.

So I would try to add the implementation dependency and remove the task
