I'm using a notification to let the user now that the service is still running. Now I'd like to use the notificationlight to remind the user. (because it's fancy)
The notification works fine, but the notification light does nothing. Other applications work fine with the notification light, (gtalk, facebook)
it's more or less the example code for notifications with addition of these flags:
notification.ledARGB = 0xff00ff00;
notification.ledOnMS = 100;
notification.ledOffMS = 100;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.flags |= Notification.FLAG_NO_CLEAR + Notification.FLAG_ONGOING_EVENT;
mNotificationManager.notify(NOTIFICATION_ID, notification);
and
notification.defaults |= Notification.DEFAULT_LIGHTS;
instead doesn't work either.
I'm debugging on a Galaxy Nexus with Android 4.0, but the app's target is Android 2.3.3
EDIT:
could this be a problem of permission? If yes, which one? I looked through all and found no matching permission for the notification light.
I think there is an error with the + operator, you need the OR:
notification.flags |= Notification.FLAG_NO_CLEAR | Notification.FLAG_ONGOING_EVENT;
EDIT: and if you are using flags, I think the right one should be:
notification.flags |= Notification.FLAG_SHOW_LIGHTS
On jelly bean devices, led only works if notification priority is set to max or default, please check again. Following snippet of code is working fine for me on jb devices.
notification.setLights(0xFF0000FF,100,3000);
notification.setPriority(Notification.PRIORITY_DEFAULT);
Here I'm showing blue color led for notification which will remain on for 100 ms and off for 3000 ms till user unlocks his device.
And check if you are using NotificationCompat (compatibility) class than ignore setDefaults method and use SetLight, SetSound, Setvibration, etc

I developed android app which sends a notification in a particular time. The notifications works great and it shows arabic and english text well. but when i run the app on android device Nexus 5 with android version 5.1.1, the text notification in arabic appears as in a photo
Here's the code i used..
android.app.Notification notification = new android.app.Notification(R.drawable.ic_launcher,ticker, System.currentTimeMillis());
notification.setLatestEventInfo(activity, title, text, pendingIntent);
// Cancel the notification after its selected
notificationIntent.setAction(Long.toString(System.currentTimeMillis()));
// notificationIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT | Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
notification.flags |= android.app.Notification.FLAG_AUTO_CANCEL;
notification.defaults |= android.app.Notification.DEFAULT_SOUND;
notification.defaults |= android.app.Notification.DEFAULT_VIBRATE;
NotificationManager notificationManager = (NotificationManager)activity.getSystemService(activity.NOTIFICATION_SERVICE);
notificationManager.notify(Id++, notification);
Try To use Arabic Reshaper
I used it to display arabic in law APIs before
https://github.com/agawish/Better-Arabic-Reshaper/blob/master/src/org/amr/arabic/ArabicReshaper.java
So I am writing an app that will use the LED to notify users of anything when the screen is OFF. Below is how I used it to work:
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification();
notification.ledARGB = 0xFFFFFF00;
notification.flags = Notification.FLAG_SHOW_LIGHTS;
notification.ledOnMS = 100;
notification.ledOffMS = 100;
notificationManager.notify(Constants.LED_NOTIFICATION_ID, notification);
It works fine, but problem occurs when my device (Galaxy S5) has missed calls, and the stock LED notification for missed calls overrides my LED setting all the time. Is there a way to override the stock LED settings, and have it display mine instead? I've tried fiddling with
notification.priority
but that doesn't seem to do anything. Any help would be appreciated. Thanks!

Not in general. Control over the LED is up to the device manufacturer, not you. Or, quoting the documentation, "Since hardware varies, you are not guaranteed that any of the values you pass are honored exactly."
Also, bear in mind that not all devices have LEDs that a Notification can control, sometimes because the device does not have an LED at all.
The following code works great on a Motorola Defy with Android 2.3.3
However it's not working on a Nexus 4. The LED itself should be fine, the app color led tester from the market works.
NotificationManager notif = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
final Notification notification = new Notification();
notification.ledARGB = Color.RED;
notification.ledOnMS = 1000;
notification.ledOffMS = 300;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notif.notify(1, notification);
Does anybody know what will do the trick here?
I just have tested your code on my Nexus 4 and it's work. But before the test I have locked my phone. Probably this LED will be highlighted only when screen is off.
The notification bar in my application shows only the small icon in the ticker (as it should). However, when the "shade" is pulled down, it shows both the small icon from the ticker, as well as a large icon that I set in the Notification.Builder. Here's my code:
if (Build.VERSION.SDK_INT > 10){
notification = new Notification(R.drawable.ic_stat_mintchip,
"This is a test",
System.currentTimeMillis());
notification.largeIcon = (((BitmapDrawable)c.getResources().getDrawable(R.drawable.ic_launcher)).getBitmap());
notification.defaults |= Notification.DEFAULT_ALL;
notification.number += 1;
notification.flags |= Notification.FLAG_AUTO_CANCEL;
} else {
notification = new Notification(R.drawable.ic_stat_mintchip,
"This is a test",
System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.defaults |= Notification.DEFAULT_ALL;
notification.number += 1;
}
}
I don't quite know why this is happening. Any assistance?
I think the issue here is possibly that you're not using the Notificaiton.Builder class. Here's a small example of what you could do (you would have to insert your own variables though, and set the other properties that you used such as vibration):
Notification.Builder nb = new Notification.Builder(context)
.setContentTitle("title")
.setContentText("content")
.setAutoCancel(true)
.setLargeIcon(largeIcon)
.setSmallIcon(R.drawable.small_icon)
.setTicker(s.getText());
NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
nm.notify(100, nb.build());
Another issue i had in android lollipop is that the small icon was displayed next to the large icon. To solve it - just don't set the large icon! Use only the small icon setting.

if you set your max sdk version in android manifest to 19(i.e KitKat) Your app will no longer display notifications meant for lolipop
I am using Galaxy Nexus with Android 4.0, I set the silent mode to vibrate in Settings. I use NotificationManager.notify to send the Notification. I don't set Notification.vibrate, I even use myNotification.defaults &= ~Notification.DEFAULT_VIBRATE to disable the vibration. But it still vibrate after calling NotifcationManager.notify.
Could anyone tell me how to turn off the vibration of a Notification in vibrate mode?
use the following code:
notification.defaults = Notification.DEFAULT_LIGHTS;
//or
notification.defaults = Notification.DEFAULT_SOUND;
To disable Vibration when notification comes, I use this code.
notification.vibrate = new long[] { -1 };
And its working perfectly.
To manage notification settings dynamically:
notification.defaults = Notification.DEFAULT_LIGHTS;
if(/*sound enabled*/)
notification.defaults |= Notification.DEFAULT_SOUND;
if(/*vibration enabled*/)
notification.defaults |= Notification.DEFAULT_VIBRATE;
First store the value of your vibrate setting button in shared preference. and then place this code where your notification is received.
SharedPreferences preferences = context.getSharedPreferences("VIBRATE",
0);
boolean vibrate = preferences.getBoolean("vibrate", true);
if (vibrate) {
notification.defaults |= Notification.DEFAULT_VIBRATE;
}
It can also be done using the following adb command for specific package
adb shell
cmd appops set package_name VIBRATE ignore
The above command will disable all vibrations for package_name package.
