Question

我正在按照此文档接收有关本机安卓https://github.com/evollu/react-native-fcm的推送通知，我能够收到设备令牌ID，但是当我使用从firebase手动发送时，我无法收到任何通知设备ID：

这是我的本机应用程序上的代码：

import {Platform} from 'react-native';
import FCM, {FCMEvent, RemoteNotificationResult, WillPresentNotificationResult, NotificationType} from 'react-native-fcm';

// this shall be called regardless of app state: running, background or not running. Won't be called when app is killed by user in iOS
FCM.on(FCMEvent.Notification, async (notif) => {
    // there are two parts of notif. notif.notification contains the notification payload, notif.data contains data payload
    if(notif.local_notification){
      //this is a local notification
    }
    if(notif.opened_from_tray){
      //iOS: app is open/resumed because user clicked banner
      //Android: app is open/resumed because user clicked banner or tapped app icon
    }
    // await someAsyncCall();

    if(Platform.OS ==='ios'){
      //optional
      //iOS requires developers to call completionHandler to end notification process. If you do not call it your background remote notifications could be throttled, to read more about it see https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623013-application.
      //This library handles it for you automatically with default behavior (for remote notification, finish with NoData; for WillPresent, finish depend on "show_in_foreground"). However if you want to return different result, follow the following code to override
      //notif._notificationType is available for iOS platfrom
      switch(notif._notificationType){
        case NotificationType.Remote:
          notif.finish(RemoteNotificationResult.NewData) //other types available: RemoteNotificationResult.NewData, RemoteNotificationResult.ResultFailed
          break;
        case NotificationType.NotificationResponse:
          notif.finish();
          break;
        case NotificationType.WillPresent:
          notif.finish(WillPresentNotificationResult.All) //other types available: WillPresentNotificationResult.None
          break;
      }
    }
});
FCM.on(FCMEvent.RefreshToken, (token) => {
    console.log(token)
    // fcm token may not be available on first load, catch it here
});

class App extends Component {
    componentDidMount() {
        // iOS: show permission prompt for the first call. later just check permission in user settings
        // Android: check permission in user settings
        FCM.requestPermissions().then(()=>console.log('granted')).catch(()=>console.log('notification permission rejected'));

        FCM.getFCMToken().then(token => {
            console.log(token)
            // store fcm token in your server
        });

        this.notificationListener = FCM.on(FCMEvent.Notification, async (notif) => {
            // optional, do some component related stuff
        });

        // initial notification contains the notification that launchs the app. If user launchs app by clicking banner, the banner notification info will be here rather than through FCM.on event
        // sometimes Android kills activity when app goes to background, and when resume it broadcasts notification before JS is run. You can use FCM.getInitialNotification() to capture those missed events.
        // initial notification will be triggered all the time even when open app by icon so send some action identifier when you send notification
        FCM.getInitialNotification().then(notif => {
           console.log(notif)
        });
    }

    componentWillUnmount() {
        // stop listening for events
        this.notificationListener.remove();
    }

Answer 1

我看到您当前的问题与您安装的软件包有关。你做了一些冲突包安装。

请从您的应用中删除 io.invertase.firebase.messaging 。

npm uninstall react-native-firebase --save

然后您还需要从 settings.gradle

中删除

无法接收任何反应原生Android应用程序的推送通知
