title: No LED light for notification Android
body: <p>no matter what I tried but there is no notification light. I'm running Android 26 Oreo. My phone only displays blink light for messages and missed calls.</p>
  
  <pre><code>String CHANNEL_ID = "my_channel_01";
  NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
  CharSequence name = "Name"; // The user-visible name of the channel.
  int importance = NotificationManager.IMPORTANCE_HIGH;
  NotificationChannel mChannel = null;
  if (android.os.Build.VERSION.SDK_INT &gt;= android.os.Build.VERSION_CODES.O) {
      mChannel = new NotificationChannel("my_channel_01", name, importance);
      mChannel.enableLights(true);
      mChannel.setLightColor(Color.GREEN);
      mChannel.shouldShowLights();
      nm.createNotificationChannel(mChannel);
  }
  
  Notification notif = new Notification.Builder(MainActivity.this)
          .setSmallIcon(R.mipmap.ic_launcher_2)
          .setContentTitle("Blhas")
          .setContentText("Subject")
          .setSubText("Subtext")
          .setColor(Color.RED)
          .setLights(255, 0, 0)
          .setContentIntent(pIntent)
          .setStyle(new Notification.BigTextStyle().bigText("..."))
          .setChannelId(CHANNEL_ID)
          .setPriority(Notification.PRIORITY_HIGH)
          .build();
  nm.notify(LED_NOTIFICATION_ID, notif);
  </code></pre>
  
  <p>Is there anyway to control the LED light?</p>
