Summary:
This method was originally intended to replace the OkHttp client used by React Native's networking library. However it has effectively been a noop since 0a71f48b13 (diff-177100ae5a977e4060b54cc2b34c79a7), when the Networking library was modified to create a new client rather than use the reference provided by OkHttpClientProvider.
Leaving this code in place is dangerous. There is no indication to users upgrading React Native that the method is no longer replacing the OkHttpClient used by the Networking library. Any functionality reliant on overriding the client will silently break. This caused us some problems internally.
There's been a PR out for some time that seeks to reintroduce this functionality: https://github.com/facebook/react-native/pull/14068
I've also put up a new PR that adds an interface for replacing the client without introducing breaking changes: https://github.com/facebook/react-native/pull/17237
Do our unit tests continue to pass? Should be safe as this method is not used anywhere inside React Native.
[ANDROID] [BREAKING] [Networking] - removed replaceOkHttpClient method in OkHttpClientProvider.

React Native · 
Learn once, write anywhere: Build mobile apps with React.
See the official React Native website for an introduction to React Native.
Requirements
Supported target operating systems are >= Android 4.1 (API 16) and >= iOS 9.0. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS by default (tools like Expo can be used to get around this).
Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
How React Native works
React Native lets you build mobile apps using JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components.
With React Native, you don't build a "mobile web app", an "HTML5 app", or a "hybrid app". You build a real mobile app that's indistinguishable from an app built using Objective-C, Java, Kotlin, or Swift. React Native uses the same fundamental UI building blocks as regular iOS and Android apps. You just put those building blocks together using JavaScript and React.
React Native lets you build your app faster. Instead of recompiling, you can reload your app instantly. With hot reloading, you can even run new code while retaining your application state.
React Native combines smoothly with components written in Objective-C, Java, Kotlin, or Swift. It's simple to drop down to native code if you need to optimize a few aspects of your application. It's also easy to build part of your app in React Native, and part of your app using native code directly - that's how the Facebook app works.
The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native. You can learn more about our open source roadmap in this blog post: Open Source Roadmap.
Full documentation
The full documentation for React Native can be found on our website. The source for the React Native documentation and website is hosted on a separate repo, https://github.com/facebook/react-native-website. Releases are discussed in the React Native Community, https://github.com/react-native-community/react-native-releases, and larger discussions and proposals are in https://github.com/react-native-community/discussions-and-proposals.
The React Native documentation only discusses the components, APIs, and topics specific to React Native (React on iOS and Android). For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
