-# The `/android` folder inside `react-native`
-
-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.
