Firebase推送通知 [英] Firebase Push Notification

问题描述

我在Android应用中实现了Firebase的推送通知功能.我实现了两个服务，用于注册令牌和在检测到令牌时创建通知.当我的应用程序启动时，它可以工作，但是当我的应用程序关闭时，它不能工作.

I implemented Firebase for push notification in my Android app. I implemented two services for register the token and for create the notification when it is detected. When my app is launch it's working but when my app is closed it doesn't working.

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());
    }
}

还有我的清单:

    <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:

{
    "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，但是在我的情况下它不起作用.我有一个API Rest，可以调用API请求发布: https://fcm.googleapis.com/fcm/send

I already found a few solutions in StackOverflow but it doesn't work in my case. I have an API Rest which call the API Request Post : https://fcm.googleapis.com/fcm/send

所以，我的问题是:关闭应用程序后，Firebase是否可以处理推送通知?如何处理?

So, there is my question : Does Firebase handle push notification when the app is closed and how to ?

谢谢您的回答

推荐答案

当应用关闭时，FCM会支持通知.您的代码似乎还可以，因此我认为电池省电器(或节电器)可以杀死您的通知.我的华硕Zenfone遇到了此类问题，在使用华为和小米的情况下也有报告.只需禁用它们或将您的应用添加到例外列表(如果有).在最新版本的Android中还提供了一种新的省电模式，也请尝试将其禁用.

FCM does support notifications when app is closed. Your code seems to be OK, so I suppose battery economizers (or power savers) can kill your notifications. I had such problems on my Asus Zenfone, also they were reported in cases of using Huawei and Xiaomi. Just disable them or add your app in exception list, if there is one. Also there is a new power-saving mode in recent releases of Android, try to disable it too.
