无法清除通知并从通知中打开片段

Question

I am trying to clear notification. But it remains there. Not able to open fragment Activity from notification. Below is my code,

 @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        int sticky;

        try {
            AndroidLogger.log(5, TAG, "Missed call notification on start");
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                int importance = NotificationManager.IMPORTANCE_HIGH; //Important for heads-up notification
                NotificationChannel channel = new NotificationChannel("1", "Call Notification", importance);
                channel.setDescription("Get alert for missed call");
                channel.setShowBadge(true);
                channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
                NotificationManager notificationManager = getSystemService(NotificationManager.class);
                notificationManager.createNotificationChannel(channel);
            }
            Intent notifyIntent = new Intent(this, ViewFragment.class);
            notifyIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


            PendingIntent pIntent = PendingIntent.getActivity(this, 0, notifyIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT);
            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, "1")
                    .setSmallIcon(R.drawable.nexge_logo)
                    .setContentTitle("Missed Call")
                    .setContentText(intent.getStringExtra("Number"))
                    .setContentIntent(pIntent)
                    .setAutoCancel(true)
                    .setPriority(Notification.PRIORITY_MAX);

            Notification buildNotification = mBuilder.build();
            NotificationManager mNotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            //mNotifyMgr.notify(1, buildNotification);

            startForeground(1,buildNotification);
        } catch (Exception exception) {
            AndroidLogger.error(1, TAG, "Exception while starting service", exception);
        }
        return START_NOT_STICKY;
    }
}

Anybody help me to solve this. Thanks in Advance. Below is my another question for which I didn't get a proper answer. Help me with that also About Notification for Missed Call in android

Answer 1

My solution to a similar issue has been changing PendingIntent Flag to PendingIntent.FLAG_ONE_SHOT From Android documentation:

Flag indicating that this PendingIntent can be used only once. For use with getActivity(Context, int, Intent, int), getBroadcast(Context, int, Intent, int), and getService(Context, int, Intent, int).

If set, after send() is called on it, it will be automatically canceled for you and any future attempt to send through it will fail.

and adding notification FLAG_AUTO_CANCEL flag:

mBuilder.flags |= Notification.FLAG_AUTO_CANCEL;

which should make sure the notification will be removed once used.

Edit : Should call

Notification notification = mBuilder.build();

first, then

notification.flags = Notification.FLAG_AUTO_CANCEL;

Edit2 : Just noticed that you are using the notification for startForeground() . This means that the notification will stay for as long as your Service / Activity is running (this is by default so the user will know that there is a Service / Activity still running).

The notification will stay for as long as your Service / Activity does run as foreground service.
