How to implement React-native bridging Android and what are the specific steps?
This article mainly introduces the detailed explanation of React-native bridging Android native development. Now I share it with you and give you a reference.
In the long journey of developing RN, sooner or later one will have to come into contact with native Android development. The author will introduce the ups and downs. For a novice who does not understand Android, it is a bit difficult at the beginning. But everything is difficult at the beginning. The language is clear, and the principle is the same.
During the development process, we need to integrate the navigation function of Amap, but we have not found a good one. For the wheel, just write the native code, and then use JS to call the native navigation module.
First register the module
The meaning is to register the class to RN , you can use JS to call
public class AnExampleReactPackage implements ReactPackage { @Override public List<ViewManager> createViewManagers(ReactApplicationContext reactContext) { return Collections.emptyList(); } @Override public List<NativeModule> createNativeModules(ReactApplicationContext reactContext) { List<NativeModule> modules = new ArrayList<>(); modules.add(new NaviActivity(reactContext)); return modules; } }
where modules.add(new NaviActivity(reactContext)); means adding an Android native activity module
This module can define the solution, and RN can directly Calling (@ReactMethod must be declared on the method)
@ReactMethod public void showFengMap(String mapID){ Activity currentActivity = getCurrentActivity(); Intent intent = new Intent(currentActivity, 页面名.class); currentActivity.startActivity(intent); }
The author is jumping to other pages. You can also do some other operations here. For example, go directly to share
Statement
In the MainApplication in the Android app,
@Override protected List<ReactPackage> getPackages() { return Arrays.<ReactPackage>asList( new MainReactPackage(), new AnExampleReactPackage() ); }
Add the just registered package name
JS calls the native code
import { NativeModules } from 'react-native'; export default NativeModules.NaviActivity;
The author wrote a untils/CommonAndroidUntils.js here, and directly introduced this js file into the page that needs to be used
CommonAndroidUntils.show();
to achieve the jump.
integrationAmap Navigation
For a novice to directly integrate the Amap map in android studio, it is still a little difficult at first. But after understanding it, I feel okay. Let’s simplify the problems encountered, Remind yourself to help others
The .jar voice package dragged directly cannot be imported
The solution is to right-click the .jar package and click the option to import .jar. Just wait for synchronization.
The rest are minor problems that can be easily solved based on the demo and documentation.
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future. helpful.

The React ecosystem includes state management libraries (such as Redux), routing libraries (such as ReactRouter), UI component libraries (such as Material-UI), testing tools (such as Jest), and building tools (such as Webpack). These tools work together to help developers develop and maintain applications efficiently, improve code quality and development efficiency.

Netflix uses React as its front-end framework. 1) React's componentized development model and strong ecosystem are the main reasons why Netflix chose it. 2) Through componentization, Netflix splits complex interfaces into manageable chunks such as video players, recommendation lists and user comments. 3) React's virtual DOM and component life cycle optimizes rendering efficiency and user interaction management.

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.

React is a JavaScript library developed by Meta for building user interfaces, with its core being component development and virtual DOM technology. 1. Component and state management: React manages state through components (functions or classes) and Hooks (such as useState), improving code reusability and maintenance. 2. Virtual DOM and performance optimization: Through virtual DOM, React efficiently updates the real DOM to improve performance. 3. Life cycle and Hooks: Hooks (such as useEffect) allow function components to manage life cycles and perform side-effect operations. 4. Usage example: From basic HelloWorld components to advanced global state management (useContext and

The advantages of React are its flexibility and efficiency, which are reflected in: 1) Component-based design improves code reusability; 2) Virtual DOM technology optimizes performance, especially when handling large amounts of data updates; 3) The rich ecosystem provides a large number of third-party libraries and tools. By understanding how React works and uses examples, you can master its core concepts and best practices to build an efficient, maintainable user interface.

React's main functions include componentized thinking, state management and virtual DOM. 1) The idea of componentization allows splitting the UI into reusable parts to improve code readability and maintainability. 2) State management manages dynamic data through state and props, and changes trigger UI updates. 3) Virtual DOM optimization performance, update the UI through the calculation of the minimum operation of DOM replica in memory.

React is a JavaScript library developed by Facebook for building user interfaces. 1. It adopts componentized and virtual DOM technology to improve the efficiency and performance of UI development. 2. The core concepts of React include componentization, state management (such as useState and useEffect) and the working principle of virtual DOM. 3. In practical applications, React supports from basic component rendering to advanced asynchronous data processing. 4. Common errors such as forgetting to add key attributes or incorrect status updates can be debugged through ReactDevTools and logs. 5. Performance optimization and best practices include using React.memo, code segmentation and keeping code readable and maintaining dependability
