Question

我仔细查看了所有可以找到的答案，即使在前台，特定的代码功能也无法正常工作。我尝试更改清单，更改代码，在记录器中得到的只是以下两点： D / FA：记录事件（FE）：notification_receive（_nr），...

这是我的清单文件：

using System.Linq;

[HttpGet("/questions")]
public ActionResult<List<QuestionDetails>> GetQuestions()
{
    return _quizService.GetAllQuestions()
        .Select(x => new QuestionDetails
        {
            Id = x.Id,
            Question = x.QuestionQuiz,
            ImageName = x.ImageName,
            Options = new [] { x.Option1, x.Option2, x.Option3, x.Option4 }
                .Where(option => !string.IsNullOrEmpty(option))
        })
        .OrderBy(y => Guid.NewGuid())
        .Take(10)
        .ToList();
}

这是通知服务：

<?xml version="1.0" encoding="utf-8"?>

这是应用gradle文件

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<application
    android:allowBackup="true"
    android:icon="@drawable/avatar"
    android:label="@string/app_name"
    android:roundIcon="@drawable/avatar"
    android:supportsRtl="true"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar">
    <activity android:name=".StartActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity android:name=".MainActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"/>

    <service android:name=".GettingDeviceTokenService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

    <service android:name=".NotificationService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

</application>

和GettingDeviceTokenService：

public class NotificationService extends FirebaseMessagingService {

public static  int NOTIFICATION_ID = 1;
private static final String CHANNEL_ID = "1";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    Log.d("+++", remoteMessage.toString());
    if (remoteMessage.getData().size() > 0) {
        Log.d("dataa", "Data Payload: " + remoteMessage.getData().toString());
    }

}

}

编辑：通过更改

中的GettingDeviceTokenService的意图过滤器解决了该问题。

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
defaultConfig {
    applicationId "com.example.xghos.Wrenchy"
    minSdkVersion 21

    }

 apply plugin: 'com.google.gms.google-services'

到

package com.example.xghos.Wrenchy;

import android.util.Log;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

public class GettingDeviceTokenService extends FirebaseMessagingService {

@Override
public void onNewToken(String s) {
    super.onNewToken(s);
    Log.d("DeviceToken ==> ",  s);
}

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
}

Answer 1

您应该考虑数据消息和显示消息之间的区别。

显示消息的有效载荷带有键notification，当应用程序在后台时会自动显示，如果应用程序已在前台，则也会调用onMessageReceived()。

数据消息具有有效载荷密钥data。他们总是调用onMessageReceived()

Answer 2

您已在清单中注册了NotificationService服务。自从最新更新Firebase通知以来，同一服务将处理新令牌和收到的消息。在您的情况下，您应该仅在清单GettingDeviceTokenService中注册，因为您同时覆盖了这两种方法并删除了NotificationService。

Answer 3

尝试这种方式。完全适合我。 1.创建服务

public class YourService extends FirebaseMessagingService {

public static int NOTIFICATION_ID = 1;

@Override
public void onNewToken(String s) {
    super.onNewToken(s);
}

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(this, "2")
            .setSmallIcon(R.drawable.your_icon)
            .setContentTitle(remoteMessage.getNotification().getTitle())
            .setContentText(remoteMessage.getNotification().getBody())
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    if (NOTIFICATION_ID > 1073741824) {
        NOTIFICATION_ID = 0;
    }
    Objects.requireNonNull(notificationManager).notify(NOTIFICATION_ID++, mNotifyBuilder.build());
}

}

现在将其添加到清单

<service
   android:name=".YourService"
   android:exported="false">
   <intent-filter>
       <action android:name="com.google.firebase.MESSAGING_EVENT" />
   </intent-filter>
</service>

基于onMessageReceived的火根本无法工作
