未收到Android Firebase推送通知

我通过此链接阅读了教程，但我的设备上没有收到任何通知

我也检查并尝试了这些链接，但找不到解决方案

在我的firebase控制台中，发送的通知为0。这是我的androidManifest文件

Firebase消息服务文件

package FirebaseConnection;

import android.util.Log;

import com.google.firebase.messaging.RemoteMessage;
public class FirebaseMessagingService extends      
com.google.firebase.messaging.FirebaseMessagingService {
private static final String TAG = "FCM Service";
@Override
public void onMessageReceived(RemoteMessage remoteMessage)
{
    Log.d(TAG, "From: " + remoteMessage.getFrom());

    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());
    }

    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {
        Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
    }

}

}

还有Firebase ID服务

package FirebaseConnection;

import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;

public class FirebaseIDService extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseIDService";

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // TODO: Implement this method to send any registration to your app's servers.
    sendRegistrationToServer(refreshedToken);
}

/**
 * Persist token to third-party servers.
 *
 * Modify this method to associate the user's FCM InstanceID token with any server-side account
 * maintained by your application.
 *
 * @param token The new token.
 */
private void sendRegistrationToServer(String token) {
    // Add custom implementation, as needed.
}
}

任何帮助都将不胜感激

关于

问题是你的班名

Manifest: MyFirebaseMessagingService

Service class: FirebaseMessagingService

---

两者的名称必须相同

您可以共享MyFirebaseMessageService和FirebaseIDService类别代码吗？是否有任何异常？您的通知中是否有任何

数据

？请将您发送的消息作为通知发布。没有例外，我们将通过firebase控制台发送一条简单的hello消息，其中没有data@rogerwar按建议添加文件。

Manifest: MyFirebaseMessagingService

Service class: FirebaseMessagingService
