我正在开发一个安卓应用程序，我想在其中包含Firebase通知。我正在做的是这些代码
这是 Firebase 实例 ID 类
import android.util.Log;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;
public class FirebaseService extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseIDService";
@Override
public void onTokenRefresh() {
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d("token", "Refreshed token: " + refreshedToken);
// 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.
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
// Add custom implementation, as needed.
}
}
FirebaseMessageingService.java
import android.support.v4.app.NotificationCompat;
import android.support.v4.app.NotificationManagerCompat;
import android.util.Log;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
import digifrizz.dealer.com.sargam.Constant;
import digifrizz.dealer.com.sargam.R;
import static android.content.ContentValues.TAG;
/**
* Created by HP on 28-09-2018.
*/
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// ...
// TODO(developer): Handle FCM messages here.
// Not getting messages here? See why this may be:
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());
if (/* Check if data needs to be processed by long running job */ true) {
// For long-running tasks (10 seconds or more) use Firebase Job Dispatcher.
} else {
// Handle message within 10 seconds
handleNow();
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
}
}
private void handleNow() {
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, Constant.CHANNEL_ID)
.setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)
.setContentTitle("Notification")
.setContentText("Much longer text that cannot fit one line...")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText("Much longer text that cannot fit one line..."))
.setPriority(NotificationCompat.PRIORITY_DEFAULT);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
// notificationId is a unique int for each notification that you must define
notificationManager.notify(1, mBuilder.build());
}
@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.
sendRegistrationToServer(token);
}
private void sendRegistrationToServer(String token) {
}

我正在做的是在这篇文章 https://medium.com/android-school/test-fcm-notification-with-postman-f91ba08aacc3 通过Firebase云消息控制台和邮递员发送，但正在Android应用程序上工作。但是邮递员的回复成功了
另外，我在主活动oncreate中从此代码中获取Firebase设备令牌
String firebaseId= String.valueOf(FirebaseInstanceId.getInstance().getToken());
Log.d("firebasetoken", "Refreshed token: " + firebaseId);
任何人都可以帮我解决这个问题.
您需要指定 Firebase 项目 ID，并将其作为参数传递给 getToken(( 方法
String refreshedToken = FirebaseInstanceId.getInstance().getToken(FCM_APP_ID, "FCM");
