Firebase推送通知

Question

我在Android应用中实施了Firebase推送通知.我实现了两个服务来注册令牌,并在检测到时发出通知.当我的应用程序启动时它正在工作,但当我的应用程序关闭时,它无法正常工作.

public class FirebaseinstanceIdService extends FirebaseInstanceIdService {

    @Override
    public void onTokenRefresh() {
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.e("Firebase", refreshedToken);
        MainActivity.setFirebaseToken(refreshedToken);
    }

}

public class MyFirebaseMessageService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        //Displaying data in log
        //It is optional
        Log.e(TAG, "From: " + remoteMessage.getFrom());
        Log.e(TAG, "Notification Message Body: " + remoteMessage.getData().get("title"));

        //Calling method to generate notification
        sendNotification(remoteMessage.getData());
    }

    //This method is only generating push notification
    //It is same as we did in earlier posts
    private void sendNotification(Map<String, String> notification) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
            PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(notification.get("title"))
            .setContentText(notification.get("body"))
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

        notificationManager.notify(0, notificationBuilder.build());
    }
}

我的清单:

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

我的要求是:

{
    "to": "ex1CtVz5bbE:APA91bHiM_BCun62A9iCobF1yV26Dwn-hYCDhkYPoWEG5ZdqH0P28UsE5q1v7QibwAX7AJ290-9en9L6f548_2b7WEbJ8RPEWlIotLczjjCP7xEOWqeJk6Iz44vilWYvdu4chPwfsvXD",
    "data": {
        "title": "Notification",
        "body": "Message",
    }
}

我已经在StackOverflow中找到了一些解决方案,但它在我的情况下不起作用.我有一个API Rest,它调用API Request Post:https://fcm.googleapis.com/fcm/send

所以,我的问题是:当应用关闭时Firebase会处理推送通知吗？如何操作？

谢谢您的回答

关闭应用时,FCM会支持通知.您的代码似乎没问题,所以我认为电池节能器(或节电器)可以终止您的通知.我在Asus Zenfone上遇到过这样的问题,在使用华为和小米的情况下也有报道.只需禁用它们或在例外列表中添加您的应用程序(如果有).在Android的最新版本中还有一种新的省电模式,也尝试禁用它.
