Firebase 推送通知

Firebase Push Notification

我在我的 Android 应用程序中为推送通知实施了 Firebase。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正在运行,但当我的应用程序关闭时它不工作。

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());
    }
}

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>

还有我的要求:

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

我已经在 Whosebug 中找到了一些解决方案,但它们对我的情况不起作用。我有一个 API Rest 调用 API 请求 Post : https://fcm.googleapis.com/fcm/send

所以,我的问题是:应用程序关闭时 Firebase 是否处理推送通知以及如何处理?

感谢您的回答

FCM 支持应用关闭时的通知。您的代码似乎没问题,所以我想电池节能器(或节电器)可以终止您的通知。我在我的华硕 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。只需禁用它们或将您的应用程序添加到例外列表中(如果有)。最近发布的 Android 中还有一个新的省电模式,请尝试禁用它。
