Notification doesn't appear in foreground service

Question

I'm using the following code:

private void startForeground(boolean isActive) {
        Intent notificationIntent = new Intent(this, MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 1, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        Notification notification = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle(getString(isActive ? R.string.title_agent_active : R.string.title_agent_inactive))
                .setContentIntent(pendingIntent)
                .build();

        startForeground(1, notification);
    }

and

 @Override
    protected void onHandleIntent(Intent intent) {
        startForeground(true);
        ...

With this code notification does not appear.

But if I replace startForeground(...) with NotificationManager.notify(...) — it shows the notification, so, I think, that at least notification building code is ok.

Where could be the problem?

If you're using an IntentService the service will be destroyed as soon as onHandleIntent() method finishes execution and then, the notification will be removed.

The problem is that it does not appear at all :( – artem Jan 27 '16 at 10:02
How long does it actually take the onHandleIntent() method to return? – kleinsenberg Jan 28 '16 at 10:05

try to change the id into the other
start in onCreate() method
check the notifications are not blocked in the device
try to use these flags: noti.flags = Notification.FLAG_ONGOING_EVENT | Notification.FLAG_NO_CLEAR;
Use usual Service class

try this solution (works in my app):

private void fg() {
        Intent intent = launchIntent(this);

        PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
        mBuilder = new NotificationCompat.Builder(this);
        mBuilder.setContentTitle(getResources().getString(R.string.app_name))
            .setContentText(getResources().getString(R.string.app_name))
            .setSmallIcon(R.drawable.icon)
            .setContentIntent(pIntent);
        noti = mBuilder.build();
        noti.flags = Notification.FLAG_ONGOING_EVENT | Notification.FLAG_NO_CLEAR;
        startForeground(_.ID, noti);

    }
