当我通过Firebase网络界面向我的Android设备发送通知时,通知不会从状态栏中查看。如果我想看到通知,我必须向下滑动。即使我在Web界面中将优先级设置为High
,也会发生这种情况。这是为什么?
如果在应用程序打开时通知到达,这不是问题,因为我可以在FirebaseMessagingService
课程中自行设置优先级:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
sendNotification("Message Body");
}
/**
* Create and show a simple notification containing the received FCM message.
*
* @param messageBody FCM message body received.
*/
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, SubscribedActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_push_notification)
.setContentTitle("FCM Message")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setColor(ContextCompat.getColor(this, R.color.color_accent))
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}

打开应用程序时,您正在处理自己的通知,因此可以控制它的操作。但是,当应用程序在后台运行时,通知将由系统任务栏处理,并且您可以从Web控制台传递的唯一优先级参数是正常的。但是,如果用户不与您的应用进行交互,则通过较高的信誉将无法按预期进行。 Documentation
高优先级消息通常应导致用户与您的应用进行交互。如果FCM检测到没有这种模式,则您的邮件可能会被取消优先级。
