2020/12/10 - [React Native] - [React Native] Android 알람 구현하기 1(Push notification)-firebase

[React Native] Android 알람 구현하기 1(Push notification)-firebase

 

1.  Install the messaging module

 

npm install --save @react-native-firebase/messaging

 

 

2.  install the react-native-push-notification module

npm install --save react-native-push-notification

 

3. code 

 

hyukpush

src 폴더내에 FCMService, LocalNotificationService.js 두개를 만들었다.

 

LocalNotificationService의 코드는 다음과 같다.

import PushNotification from 'react-native-push-notification';
import PushNotificationIOS from '@react-native-community/push-notification-ios';
import {Platform} from 'react-native';

class LocalNotificationService {
  configure = (onOpenNotification) => {
    PushNotification.configure({
      onRegister: function (token) {
        console.log(
          '[LocalNotificationService] onRegister : localtoken',
          token,
        );
      },
      onNotification: function (notification) {
        console.log('[LocalNotificationService] onNotification ', notification);
        if (!notification?.data) {
          return;
        }
        notification.userInteraction = true;
        onOpenNotification(
          Platform.OS === 'ios' ? notification.data.item : notification.data,
        );

        //Only call callback if not from foreground
        if (Platform.OS === 'ios') {
          // (required) Called when a remote is received or opened, or local notification is opened
          notification.finish(PushNotificationIOS.FetchResult.NoData);
        }
      },

      // IOS ONLY (optional): default: all - Permissions to register.
      permissions: {

hyukpush 부분을 각자의 appname으로 바꿔줘야한다.

 

 

이걸로 android는 끝이다. 한번 메세지를 보내보자

 

 

firebase

좌측에 성장 > Cloud Messagin을 누르면 위와 같은 페이지가 나온다.

 

새알림을 누르고

 

다음 

안드로이드를 선택해주자

 그리고 다음다음 완료를 눌러준다.

 

 

짜잔~!~! 

모두 다함께 열코합시다 ㅎㅎㅎㅎㅎ

위 화면은 Background상태에서 실행한 것이다 ~
