I am building an android application with Typescript, CapacitorJS, React, React-Router-Dom, and BlueprintJS.
When I execute React application in the web browser environment, Every component which I have written is normally rendered.
After Building React App, I have installed node.js packages @capacitor/core@next @capacitor/cli@next @capacitor/android@next. I run commands “yarn cap init --web-dir=build”, “yarn cap add android”, and “yarn cap open android”.
I have built a node.js express backend API server with port 5000, I wrote the line, android:usesCleartextTraffic=“true” in AndroidManifest.xml. Capacitor App in Android would request to the localhost backend server, the API address that mobile client request has been changed “10.0.2.2:5000”.
In Android Studio, no errors found. After clicking the “Run” button, a mobile emulator turns on, and the capacitor app is executed.
In the mobile environment, I cannot see anything on the virtual device, except the component Header. The component Header is not in the Switch group.
How can I render the components in React Router Dom in the android environment?
Here are my codes, React App.tsx, package.json, and AndroidManifest.xml.
App.tsx
import { BrowserRouter as Router, Switch, Route } from 'react-router-dom';
import Header from './components/Header';
import PostMain from './PostList';
import PostItem from './PostItem';
import SearchList from './SearchList';
import CommentEdit from './CommentEdit';
import CommentDelete from './CommentDelete';
import SourceList from './SourceList';
const App = () => {
return (
<Router>
<div
style={{
maxWidth: '920px',
width: '100%',
margin: '0 auto 20px',
padding: '0px',
}}
>
<Header />
<Switch>
<Route exact path="/" component={PostMain} />
<Route exact path="/id/:id" component={PostItem} />
<Route exact path="/source/:id" component={SourceList} />
<Route exact path="/search/:keyword" component={SearchList} />
<Route exact path="/comments/edit/:id" component={CommentEdit} />
<Route exact path="/comments/delete/:id" component={CommentDelete} />
</Switch>
</div>
</Router>
);
};
export default App;
