【问题描述】：

我最近在我的 React Native 应用程序中设置了推送通知，它在 ios 中运行良好，但在 android 中无法弹出。这是我为触发通知而调用的函数。

function pushNotif() 
        PushNotification.localNotification(
                channelId: "specialid", // (required) channelId, if the channel doesn't exist, notification will not trigger.
                title: "hello",
                message: "test message"
        )

这是我在上面配置推送通知的地方

// Must be outside of any component LifeCycle (such as `componentDidMount`).
PushNotification.configure(
   // (optional) Called when Token is generated (iOS and Android)
   onRegister: function (token) 
   console.log("TOKEN:", token);
    ,

    // (required) Called when a remote is received or opened, or local notification is opened
    onNotification: function (notification) 
        console.log("NOTIFICATION:", notification);     
    // process the notification   
    // (required) Called when a remote is received or opened, or local notification is opened
        notification.finish(PushNotificationIOS.FetchResult.NoData);
            ,
    // (optional) Called when Registered Action is pressed and invokeApp is false, if true onNotification will be called (Android)
    onAction: function (notification) 
        console.log("ACTION:", notification.action);
        console.log("NOTIFICATION:", notification);
            // process the action
            ,
            // (optional) Called when the user fails to register for remote notifications. Typically occurs when APNS is having issues, or the device is a simulator. (iOS)
     onRegistrationError: function(err) 
           console.error(err.message, err);
            ,
     // IOS ONLY (optional): default: all - Permissions to register.
            permissions: 
                alert: true,
                badge: true,
                sound: true,
            ,
     // Should the initial notification be popped automatically
            // default: true
            popInitialNotification: true,
            /**
             * (optional) default: true
             * - Specified if permissions (ios) and token (android and ios) will requested or not,
             * - if not, you must call PushNotificationsHandler.requestPermissions() later
             * - if you are not using remote notification or do not have Firebase installed, use this:
             *     requestPermissions: Platform.OS === 'ios'
             */
            requestPermissions: true,
            );

正如我所说，它在 iOS 上运行良好，当我删除 channelId（我知道它是 android 所必需的）时，我收到了这条消息...... No Channel ID Passed. Notification may not work

这让我相信它正在以某种方式进行配置，但并不完全。

以下是我的其余配置文件：https://github.com/zo0r/react-native-push-notification

在android/build.gradle

buildscript 
    ext 
        googlePlayServicesVersion = "+" // default: "+"

        buildToolsVersion = "29.0.3"
        minSdkVersion = 21
        compileSdkVersion = 30
        targetSdkVersion = 30
        ndkVersion = "20.1.5948944"
    
    repositories 
        google()
        jcenter()

        classpath 'com.google.gms:google-services:4.3.10'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

...

在android/app/src/main/java/com/app_name/MainActivity.java

...
import com.facebook.react.ReactActivity;
import android.content.Intent;



public class MainActivity extends ReactActivity 

  /**
   * Returns the name of the main component registered from javascript. This is used to schedule
   * rendering of the component.
   */
  @Override
  public void onNewIntent(Intent intent) 
      super.onNewIntent(intent);
  
  @Override
  protected String getMainComponentName() 
    return "cjcChatApp";
  

我怎样才能让它在 Android 上运行？

【参考方案1】：

我想你忘了创建 chanel，你可以试试这个：

function pushNotif()
  PushNotification.createChannel(
    
      channelId: "specialid", // (required)
      channelName: "Special messasge", // (required)
      channelDescription: "Notification for special message", // (optional) default: undefined.
      importance: 4, // (optional) default: 4. Int value of the Android notification importance
      vibrate: true, // (optional) default: true. Creates the default vibration patten if true.
    ,
    (created) => console.log(`createChannel returned '$created'`) // (optional) callback returns whether the channel was created, false means it already existed.
  );
  PushNotification.localNotification(
    channelId:'specialid', //his must be same with channelid in createchannel
    title:'hello',
    message:'test message'
  )
