Summary: With the current ways metro location is determined, when we want to use a different metro port this requires app to be rebuild as the port and location are stored in resource file that gets compiled to R.class. The only way to avoid app rebuild due to a port change is to use shared preferences that can be accessed from dev menu, where metro URL can be specified. However, due to a separate code-paths for retrieving bundle location and for `/inspector/device` calls, the setting only applies to the former. As a consequence, you can change metro URL in the shared preferences, but debugging would only work if you use the default port or you rebuild the app with the correct port number. This PR removes the separate code-path for retrieving inspector URL including all the dependencies scattered across different files including the gradle plugin. We then replace calls to `PackagerConnectionSettings.getInspectorServerHost` with `PackagerConnectionSettings.getDebugServerHost` which respects the shared preferences and other possible ways of configuring the port. I decided to remove the separate inspector URL code path, as the resource value for inspector port added in https://github.com/facebook/react-native/issues/23616 was never functioning properly due to a bug. In the said PR introduced a bug in [AndroidInfoHelpers.java](https://github.com/facebook/react-native/blob/a13d51ff1c38ea85e59f4215563c0dd05452f670/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/modules/systeminfo/AndroidInfoHelpers.java#L77) where `react_native_dev_server_port` was used instead `react_native_inspector_proxy_port`. As a result the added resource value was never read. This can be potentially a breaking change as I'm removing some public methods. However I think it is unlikely anyone relied on said methods. As a part of this PR I'm also changing occurences of removed methods from ReactAndroid.api – I don't know how to test those changes since I don't understand how this file is used as it doesn't have any references in public code. ## Changelog: [ANDROID] [FIXED] - Make Android respect metro location from shared preferences for the debugger workflow Pull Request resolved: https://github.com/facebook/react-native/pull/42617 Test Plan: 1. Run android app on emulator using default port 2. Check the debugger works when using "Open Debugger" option from dev menu 3. Restart metro with custom port (`--port 9090`) while keeping the app running 4. Open dev menu, click "Settings" then "Debug server host & port", put "10.0.2.2:9090" there 5. Reload the app 6. Before this change things like hot reload would continue to work while "Open Debugger" option would do nothing 7. After this change both reloading and debugging will work Important: I haven't tested changes made to ReactAndroid.api as I don't know what this files is used for with no references in the codebase.

React Native
Learn once, write anywhere:
Build mobile apps with React.
Getting Started · Learn the Basics · Showcase · Contribute · Community · Support
React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 13.4 and Android 6.0 (API 23) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work 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:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repo, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in this discussion repo.
