Firebase 云消息传递：android 12 后未收到消息

Question

我正在尝试使用 Firebase 消息服务向 android 12 设备 发送推送通知。当我尝试从 nodeJs 发送 FCM 时，调用 onMessageReceived not。我尝试从 Firebase 控制台发送 FCM，但即使该应用程序在后台，该应用程序也没有显示任何通知或错误。我已经在 android 11 和 android 10 中测试了这个应用程序，两者都工作正常。

您好，您的清单文件格式不正确，请检查下面的清单并进行相应调整，同时确保您有 FirebaseMessagingService

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@mipmap/ic_launcher" />
    <meta-data
        android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/colorAccent" />
    <meta-data
        android:name="com.google.firebase.messaging.default_notification_channel_id"
        android:value="@string/default_notification_channel_id" />

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

同时检查您的 build.gradle 并添加以下依赖项左大括号

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

您的 FirebaseMessagingService 应采用以下格式：

public class MyFirebaseMessagingService  extends FirebaseMessagingService {


@Override
public void onMessageReceived(RemoteMessage message) {
    String from = message.getFrom();
    Map data = message.getData();

    Log.e("Message", "Could not parse malformed JSON: \"" + data.toString() + "\"");

    //generateNotification(getApplicationContext(), data);
}

@Override
public void onNewToken(String token) {

    //Log.d(TAG, "Refreshed token: " + token);

    // If you want to send messages to this application instance or
    // manage this apps subscriptions on the server side, send the
    // Instance ID token to your app server.
    Toast.makeText(getApplicationContext(),"Token "+token,Toast.LENGTH_LONG).show();
    //App.getInstance().setGcmToken(token);

}

@Override
public void onDeletedMessages() {
    sendNotification("Deleted messages on server");
}

@Override
public void onMessageSent(String msgId) {

    sendNotification("Upstream message sent. Id=" + msgId);
}

// Put the message into a notification and post it.
// This is just one simple example of what you might choose to do with
// a GCM message.
private void sendNotification(String msg) {

    Log.e("Message", "Could not parse malformed JSON: \"" + msg + "\"");
}

}

对于可能遇到这个问题的新人，我遇到了完全相同的问题：
就我而言，我仍在使用具有旧的已弃用架构的 Firebase 库 17.x。
现在我将 firebase 依赖更新到版本 23.0.4，它工作得很好。
