+# 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.
