推荐项目：React Native Android通知监听器

在React Native中创建一个Android通知监听器可以通过原生模块来实现。以下是一个简单的例子，展示了如何创建一个监听器并在通知更新时接收通知。

首先，你需要创建一个React Context和一个自定义的ReactPackage来注册你的原生模块。

// NotificationListenerPackage.java
 
package com.yourpackage;
 
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.util.Log;
 
import com.facebook.react.bridge.Arguments;
import com.facebook.react.bridge.ReactContext;
import com.facebook.react.bridge.WritableMap;
import com.facebook.react.modules.core.DeviceEventManagerModule;
 
public class NotificationListenerService extends android.service.notification.NotificationListenerService {
 
    private static final String TAG = "NotificationListener";
 
    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        sendEvent(sbn, "notification_posted");
    }
 
    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {
        sendEvent(sbn, "notification_removed");
    }
 
    private void sendEvent(StatusBarNotification sbn, String eventName) {
        WritableMap params = Arguments.createMap();
        params.putString("package", sbn.getPackageName());
        params.putString("id", String.valueOf(sbn.getId()));
        params.putString("tag", sbn.getTag());
        // You can add more data if needed
 
        ReactContext reactContext = MyReactApplication.getCurrentReactContext();
        reactContext.getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
                .emit(eventName, params);
    }
}
 
// MyReactPackage.java
 
package com.yourpackage;
 
import com.facebook.react.ReactPackage;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.uimanager.ViewManager;
 
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
 
public class MyReactPackage implements ReactPackage {
 
    @Override
    public List<NativeModule> createNat
