I have a phone under Android 8 and I begin Android programmation with Android Studio. Some apps like Snapchat or Facebook makes my phone light a led with their custom colors (yellow & blue) when a notification comes.
I want to do the same with my app, I searched a lot and nothing works, the notification appears but not the white light. I checked my phone settings and my app is allowed to light the led.
public class Notification
{
public Notification(String channelId, String channelName, Context context, String title, String body, Intent intent)
{
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
int notificationId = 1;
int importance = NotificationManager.IMPORTANCE_HIGH;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O)
{
NotificationChannel mChannel = new
NotificationChannel(channelId, channelName, importance);
notificationManager.createNotificationChannel(mChannel);
}
NotificationCompat.Builder nbuilder = new NotificationCompat.Builder(context, channelId)
.setLights(Color.WHITE, 500, 100) // doesn't work
.setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 }) // doesn't work
.setContentTitle(title)
.setContentText(body);
TaskStackBuilder stackBuilder =
TaskStackBuilder.create(context);
stackBuilder.addNextIntent(intent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
nbuilder.setContentIntent(resultPendingIntent);
notificationManager.notify(notificationId, nbuilder.build());
}
}
I tried calling the setLights() and setVibrate() after setContentText() and I tried calling these voids just before the notify() but it didn't changed anything.
I instanciate my class in the onCreate() :
new Notification("channel-01", "MathWellan Notification", this, "Twitter", "Follow me on Twitter !", new Intent(Intent.ACTION_VIEW, Uri.parse("twitter://user?screen_name=MathWellan")));
Sorry for my bad english, I'm french and I hope you can help me !
Thanks by advance :)
Use this line of code to change notification LED color: your_notification.ledARGB = Color.YOUR_COLOR;
Usage example:
NotificationManager notif = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notif.cancel(1); // clear previous notification
final Notification notification = new Notification();
notification.ledARGB = Color.MAGENTA;
notification.ledOnMS = 1000;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notif.notify(1, notification);
Note : screen should be locked when you test it , because notification LED will be highlighted only when screen is off. Maybe that's your problem.

I have been trying to create an incoming call type notification for my Android app, written in native Java code, and in many resources online I have read that using the .setOngoing(true) tag on the NotificationBuilder would be enough to have the desired behaviour of the notification being visible, playing the ringtone sound until it is clicked, but that has not worked for me.
I have also tried using the flags Notification.FLAG_INSISTENT and Notification.FLAG_NO_CLEAR without success.
Here is my current code:
private void ringtone(Context context){
String channelId = "call_channel";
Intent notificationIntent = new Intent(context, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_IMMUTABLE);
Uri ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context, channelId)
.setSmallIcon(R.drawable.ic_launcher_background)
.setContentTitle("Incoming Call")
.setContentText("You have an incoming call")
.setCategory(Notification.CATEGORY_CALL)
.setOngoing(true)
.setAutoCancel(true)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setContentIntent(contentIntent);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence channelName = "Incoming Calls";
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel notificationChannel = new NotificationChannel(channelId, channelName, importance);
notificationChannel.enableVibration(true);
long[] pattern = {0, 1000, 500, 1000};
notificationChannel.setVibrationPattern(pattern);
AudioAttributes att = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_NOTIFICATION_RINGTONE)
.setLegacyStreamType(AudioManager.STREAM_RING)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
notificationChannel.setAllowBubbles(true);
}
notificationChannel.setLockscreenVisibility(NotificationCompat.VISIBILITY_PUBLIC);
notificationChannel.setSound(ringtoneUri,att);
notificationManager.createNotificationChannel(notificationChannel);
}else{
notificationBuilder.setSound(ringtoneUri);
}
Notification notification = notificationBuilder.build();
notification.flags |= Notification.FLAG_INSISTENT | Notification.FLAG_NO_CLEAR;
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);
}
My intention is to have an incoming call type of notification much like other applications such as MS Teams, Whatsapp, ETC. and my issue is that the notification gets minimized after showing on screen for a few seconds, and the ringtone stops shortly after. Thank you for any help with this.
I am sharing two images please have a look on it you will understand my problem
in fist image notification comes successfully as shown better me notification but
I want it to come and show first on main screen as shown in second image just this telegram notification.
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
// r.play();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
r.setLooping(false);
}
// vibration
Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
long[] pattern = {100, 300, 300, 300};
v.vibrate(pattern, -1);
int resourceImage = getResources().getIdentifier(remoteMessage.getNotification().getIcon(), "drawable", getPackageName());
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "CHANNEL_ID");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
builder.setSmallIcon(R.mipmap.betterme);
} else {
builder.setSmallIcon(R.mipmap.betterme);
}
Intent resultIntent = new Intent(this, SplashScreen.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 1, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentTitle(remoteMessage.getNotification().getTitle());
builder.setContentText(remoteMessage.getNotification().getBody());
builder.setContentIntent(pendingIntent);
builder.setStyle(new NotificationCompat.BigTextStyle().bigText(remoteMessage.getNotification().getBody()));
builder.setAutoCancel(true);
builder.setOngoing(true);

channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_HIGH);
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_NOTIFICATION)
.build();
channel.setSound(notification, audioAttributes);
mNotificationManager.createNotificationChannel(channel);
builder.setChannelId(channelId);
}
mNotificationManager.notify(100, builder.build());
}
}

If I understand correctly, you would like to have a heads up notification.
Note, that the android system decides when to make a notification a heads up notification and has the final say - not you the developer. Here you can find some examples when it does so: https://developer.android.com/guide/topics/ui/notifiers/notifications#Heads-up
Make sure that your setup reflects these. From your sample it seems to be the case, but maybe you have changed the notification channel settings (from the app settings), which override your code preferences (the user has precedence over the app).
Additionally, note that if you swipe the heads up notification in a upward direction (not sideways), Android starts a cool off time, where no heads up notifications from that app appears for a few seconds (or more). You can try that with Telegram or any other app as well. After the cool-off time, it starts showing up again like a heads up notification. This is a way Android utilises to prevent apps to be annoying to users.
Seems there is no problem in the notification. But your channel is already created with normal notification and you update to IMPORTANCE_HIGH for NotificationChannel.
Once the channel is created with priority it cannot be changed. So you can either change the channel id or uninstall and reinstall and test it.
I am making an application that gathers push notifications with NotificationListenerService in Android.
Retrieving notification contents such as the name of the app, contents of the app, package name, notification registered time etc. works very well.
However, when trying to retrieve notifications Intent that redirects the user to a specific Activity of an app when clicked, doesnt work. It won't get Intent. What might be the problem?
try {
//ne.cls_intent = getIntent(sbn.getNotification().contentIntent).toString();
ne.cls_intent =getIntent(notification.contentIntent).resolveActivity(pm).getClassName();
} catch (IllegalStateException e) {
ne.cls_intent = "No Intent";
}
Try this, #Hyeon
Intent intent = new Intent(getApplicationContext(), Your_Desired_Activity.class);
intent.putExtra("Key", value); //for sending data to your specific activity if needed.
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), (int) (Math.random() * 100), intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationManager mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
String NOTIFICATION_CHANNEL_ID = "101";
//TODO - make the title BOLD - change the notification icons
mBuilder = new NotificationCompat.Builder(getApplicationContext(), NOTIFICATION_CHANNEL_ID);
mBuilder.setContentTitle(message_push)
.setSmallIcon(R.drawable.app_logo)
.setContentText(event_title_push)
.setAutoCancel(true)
.setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400})
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setColor(getColor(R.color.text_color))
.setContentIntent(pendingIntent);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
CharSequence name = getString(R.string.app_name);
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, name, importance);
channel.setDescription(event_title_push);
// Register the channel with the system; you can't change the importance
// or other notification behaviors after this
mNotificationManager = getSystemService(NotificationManager.class);
channel.setImportance(importance);
mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
mNotificationManager.createNotificationChannel(channel);
}
assert mNotificationManager != null;
// Cancel the notification after the particular notification gets selected
mBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
mNotificationManager.notify((int) (Math.random() * 100) /* Request Code */, mBuilder.build());
This is the total working of showing the notification with title and vibrate and also redirecting to a specific activity.
I'm sending push notifications in my app and want to be able to show them even if the app is already running, so therefore I'm trying to use the onMessageReceived() function. The function runs whenever I send a notification and I can see that the title and body of the notification is correct, so no problems this far. Then I want the notification to pop up on the users device, but for some reason I just can't get it to work. I have looked at numerous sites and stackoverflow questions and all code basically looks the same, so it's a bit confusing why it doesn't work for me.
#Override
public void onMessageReceived(#NonNull RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String messageTitle = remoteMessage.getNotification().getTitle();
String messageBody = remoteMessage.getNotification().getBody();
System.out.println("TITLE_IS: " + messageTitle);
System.out.println("MESSAGE_BODY: "+ messageBody);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, getString(R.string.default_notification_channel_id))
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(messageTitle)
.setContentText(messageBody);
//Sets ID for the notification
int mNotificationId = (int) System.currentTimeMillis();
NotificationManager mNotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
mNotifyMgr.notify(mNotificationId, mBuilder.build());
System.out.println("Everything went fine");
}
It never prints the last line ("Everything went fine"), but also don't give an error so it seems it works even though it didn't. What is the problem and how do I fix it?
There seem to have been a recent update which requires you to run some additional code in order for it to work on newer android versions. So the code should looks something like:
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, getString(R.string.default_notification_channel_id))
.setSmallIcon(R.drawable.ic_challenge)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setPriority(Notification.PRIORITY_MAX)
.setContentIntent(pendingIntent);
//to show notification do this
//Sets ID for the notification
int mNotificationId = (int) System.currentTimeMillis();
NotificationManager mNotifyMgr = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
String channelId = "Tic-Tac-Toe";
NotificationChannel channel = new NotificationChannel(
channelId,
"Tic-Tac-Toe",
NotificationManager.IMPORTANCE_HIGH);
mNotifyMgr.createNotificationChannel(channel);
mBuilder.setChannelId(channelId);
}
mNotifyMgr.notify(mNotificationId, mBuilder.build());
i am trying to set custom ring when notification come from firebase, notification is working fine in all devices but when i set custom ringtone it not work in OREO 8 . i already applied many answer from stackoverflow. like "this" but not work for me.

thanks in advance
