android firebase通知不起作用

Question

我使用我的应用设置了Firebase消息，但遗憾的是通知未到来。

我正确设置了Firebase，它连接到我的应用程序，我还发送了一些测试消息，在Firebase中说它已完成，但我没有在手机上收到它们。

我的应用程序尚未在商店中，我正在通过android工作室开发和测试它。

这是我的MyFirebaseInstanceIDService类

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

private static final String TAG = "MyFirebaseIIDService";

/**
 * Called if InstanceID token is updated. This may occur if the security of
 * the previous token had been compromised. Note that this is called when the InstanceID token
 * is initially generated so this is where you would retrieve the token.
 */
// [START refresh_token]
@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);
}
// [END refresh_token]

/**
 * 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.
}

}

这里是MyFirebaseMessagingService类：

公共类MyFirebaseMessagingService扩展FirebaseMessagingService {private static final String TAG =“MyFirebaseMsgService”;

/**
 * Called when message is received.
 *
 * @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
 */
// [START receive_message]
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // [START_EXCLUDE]
    // There are two types of messages data messages and notification messages. Data messages are handled
    // here in onMessageReceived whether the app is in the foreground or background. Data messages are the type
    // traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app
    // is in the foreground. When the app is in the background an automatically generated notification is displayed.
    // When the user taps on the notification they are returned to the app. Messages containing both notification
    // and data payloads are treated as notification messages. The Firebase console always sends notification
    // messages. For more see: https://firebase.google.com/docs/cloud-messaging/concept-options
    // [END_EXCLUDE]


    //"Title","Message","NotyType",   "hotelStatus"

    String title = "";
    if (remoteMessage.getNotification().getTitle() != null){
        title = remoteMessage.getNotification().getTitle();
    }

    String message = "";
    if (remoteMessage.getNotification().getBody() != null){
        message = remoteMessage.getNotification().getBody();
    }

    Log.e("notification","recieved");


    sendNotification(title, message);
    // 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.
}
// [END receive_message]


private void sendNotification(String title, String body) {
    Intent i = new Intent(this, MainActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pi = PendingIntent.getActivity(this,
            0 /* Request code */,
            i,
            PendingIntent.FLAG_ONE_SHOT);

    Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this,
            getString(R.string.default_notification_channel_id))
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(title)
            .setContentText(body)
            .setAutoCancel(true)
            .setSound(sound)
            .setContentIntent(pi);

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

    assert manager != null;
    manager.notify(0, builder.build());
} }

调试时我没有看到任何日志，也没有在手机上收到任何通知。

我在这里做错了吗？你能给些建议么？谢谢。
