Question

当应用处于前台和后台时，我收到通知。但是当我关闭应用程序时，没有收到任何通知。

这是我的宣言

        <service android:name="com.vfi.fcm.AppInstanceIDListenerService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
        </intent-filter>
    </service>
    <service android:name="com.vfi.fcm.AppFcmListenerService"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

这是FCM侦听器类

public class AppFcmListenerService extends FirebaseMessagingService {

private static final String TAG = "FCM - Msg";
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    Map<String, String> data = remoteMessage.getData();
    Set keys = data.keySet();

    for (Iterator i = keys.iterator(); i.hasNext(); ) {
        String key = (String) i.next();
        Log.e("key",key);
        String value = (String) data.get(key);
        sendNotification(null, value);
        Log.e("value",value);
    }

}

private void sendNotification(String type, String message) {
    Random random = new Random();
    int Unique_Integer_Number = random.nextInt(9999 - 1000) + 1000;
    Intent intent = new Intent(this, LoginActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(
            getApplicationContext(), Unique_Integer_Number, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationManager nManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    builder.setContentTitle(AppControl.getInstance().getAppName());
    builder.setContentText(message);
    builder.setSmallIcon(R.mipmap.ic_launcher);
    builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
    builder.setSound(defaultSoundUri);
    builder.setAutoCancel(true);
    builder.setContentIntent(pendingIntent);
    builder.setStyle(new NotificationCompat.BigTextStyle()
            .bigText(message));
    nManager.notify(AppControl.getInstance().getAppName(), Unique_Integer_Number, builder.build());
}

我在Leeco 2设备上测试它。应用程序关闭时不会收到通知。

我已尝试过Firebase background 提供的解决方案但它都没有解决我的问题。

这是我的有效载荷

{
"data": {
"Message": "great match!"
},
"to": "fcm-id"
}

Android应用程序关闭时没有收到Firebase通知？
