当 React Native Android 应用程序在后台或已被杀死时，如何将其带到前台？

Question

Is there any way to bring a React Native app to the foreground when it is in the background or has been killed?

I have tried using react-native-invoke-app but it is no longer being maintained and only supports Android versions < 9.

Answer 1

I think the best way to do this can be setting a URL scheme and opening the url connected to the app.

1- add this line of code

<data android:scheme=“my-awesome-app” /> in ./android/app/src/main/AndroidManifest.xml under the <intent-filter> under <activity> tag.

This will give a scheme to your app which is useful in deepLinking and opening your app with a browser or while you're in other apps. Actually if you open the my-awesome-app:// url, you're app will be opened.

2- write a headless task or an event listener to run the Linking.openURL(my-awesome-app://);

this is an example from react-native-firebase message listener.

import firebase from 'react-native-firebase';
import {Linking} from 'react-native';

firebase.messaging().onMessage((message) => {
    // Process your message as required
    Linking.openURL('my-awesome-app://')
  });
}

To set the url scheme setting on iOS, you must add it in URL types in info.plist file like the picture below.
