When i run this on my android app to try and get a notification with the command: sendNotification("test","title",1);
i get an error: E/NotificationManager: notifyAsUser: tag=null, id=1, user=UserHandle{0}
private void sendNotification(String message, String title, int id) {
Intent intent = new Intent(this, Game.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */,
intent, PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.maintitle)
.setContentTitle(title)
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(this.NOTIFICATION_SERVICE);
notificationManager.notify(id /* ID of notification */,
notificationBuilder.build());
}
You must set Channel id for new android versions.
Create your notification this way
private final static String CHANNEL_ID = "my_notification";
private void sendNotification(String message, String title, int id) {
Intent intent = new Intent(this, Game.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */,
intent, PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.maintitle)
.setContentTitle(title)
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, "news_notification", NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(id /* ID of notification */,
notificationBuilder.build());
}
Set CHANNEL_ID in NotificationCompat.Builder and create channel

I tried almost every fix posted here but this code won't turn on Notification LED at all.
public void onMessageReceived(RemoteMessage remoteMessage) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
String channelId = getString(R.string.defaultChannelId);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this,channelId)
.setLights(Color.RED,200,1000)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setAutoCancel(true)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setContentTitle(remoteMessage.getNotification().getTitle())
.setContentText(remoteMessage.getNotification().getBody())
.setSmallIcon(R.drawable.omega_icon)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
Notification notification = notificationBuilder.build();
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_DEFAULT);
channel.enableLights(true);
channel.setLightColor(0xFFFFFFFF);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(1, notification);
}
I'm sending notification from Firebase and everything works perfectly fine except the LED lights. LED notification from other apps work fine.
You can't change channel color notification after Oreo/API 26.

After upgrading my app target api to 27 notification is no more working and i get a toast message on android studio emulator:
Failed to post notification on channel “null”
Here is my notification code:
private void sendNotification(Context context, String sysModel) {
Intent intentAction = new Intent(context, MainActivity.class);
intentAction.putExtra("sysModel", sysModel);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 1, intentAction, PendingIntent.FLAG_ONE_SHOT);
notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.changer_ico)
.setContentTitle(context.getString(R.string.service_ready))
.setContentIntent(pendingIntent)
.addAction(R.drawable.ic_key_black_24dp, context.getString(R.string.turn_on), pendingIntent)
.setAutoCancel(true);
Notification notification = notificationBuilder.build();
notificationManager.notify(1903, notification);
}
Can you test the code below?
Note that new NotificationCompat.Builder(context, NOTIFICATION_CHANNEL); instead of new NotificationCompat.Builder(context);
private final static String NOTIFICATION_CHANNEL = "channel_name";
private final static String CHANNEL_DESCRIPTION = "channel_description";
public final static int NOTIFICATION_ID = 1903;
private void sendNotification(Context context, String sysModel) {
// Intent
Intent intentAction = new Intent(context, MainActivity.class);
intentAction.putExtra("sysModel", sysModel);
// Pending Intent
PendingIntent pendingIntent = PendingIntent.getActivity(context, 1, intentAction, PendingIntent.FLAG_ONE_SHOT);
// Notification Manager
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Service.NOTIFICATION_SERVICE);
// Create the notification channel if android >= 8
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL, CHANNEL_DESCRIPTION, NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
// Notification builder.. Note that I added the notification channel on this constructor
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context, NOTIFICATION_CHANNEL);
notificationBuilder.setSmallIcon(R.drawable.changer_ico)
notificationBuilder.setContentTitle(context.getString(R.string.service_ready))
notificationBuilder.setContentIntent(pendingIntent)
notificationBuilder.addAction(R.drawable.ic_key_black_24dp, context.getString(R.string.turn_on), pendingIntent)
notificationBuilder.setAutoCancel(true);
// Notify
notificationManager.notify(NOTIFICATION_ID, notificationBuilder.build());
}
In android O you should dispatch notice like follow:
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.changer_ico)
.setContentTitle(context.getString(R.string.service_ready))
.setContentIntent(pendingIntent)
.addAction(R.drawable.ic_key_black_24dp, context.getString(R.string.turn_on), pendingIntent)
.setAutoCancel(true);
Notification notification = notificationBuilder.build();
NotificationChannel channel = new NotificationChannel("1903",
context.getString(R.string.user_notify), NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
notificationManager.notify(1903, notification);
when I receive the notifications, it comes without time, never showing me hour, find the below attached code.
This is my notification code
public void showBigNotification(String title, String message, String url, Intent intent) {
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
mCtx,
ID_BIG_NOTIFICATION,
intent,
PendingIntent.FLAG_UPDATE_CURRENT
);
NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle();
bigPictureStyle.setBigContentTitle(title);
bigPictureStyle.setSummaryText(Html.fromHtml(message).toString());
bigPictureStyle.bigPicture(getBitmapFromURL(url));
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mCtx);
Notification notification;
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notification = mBuilder.setSmallIcon(R.mipmap.ic_launcher).setTicker(title).setWhen(0)
.setAutoCancel(true)
.setContentIntent(resultPendingIntent)
.setContentTitle(title)
.setStyle(bigPictureStyle)
.setSound(defaultSoundUri)
.setSmallIcon(R.mipmap.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(mCtx.getResources(), R.mipmap.ic_launcher))
.setContentText(message)
.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
NotificationManager notificationManager = (NotificationManager) mCtx.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(ID_BIG_NOTIFICATION, notification);
}
Replace 0 with System.currentTimeMillis() in .setWhen() function.
.setWhen(System.currentTimeMillis())
I'm trying to start an activity by clicking on a notification but that only works when I'm already in the app.
Here's the code I think has to do with it:
private void sendNotification(String body) {
Intent intent = new Intent(ImpFirebaseMessagingService.this, codeActivity.class);
intent.putExtra("body", body);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
Uri notificationSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Implementation TFA")
.setContentText(body)
.setAutoCancel(true)
.setSound(notificationSound)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
The following works in my app:
private void sendReminderNotification(Context context) {
Resources resources = context.getResources();
Intent notificationIntent = new Intent(context, TitleActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder =
new NotificationCompat.Builder(context)
.setSmallIcon(android.R.drawable.ic_lock_idle_alarm)
.setLargeIcon(BitmapFactory.decodeResource(resources, R.drawable.my_diary_launcher_icon))
.setContentTitle("MyDiary")
.setContentText("Reminder to input entry.")
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setContentIntent(contentIntent);
// Add as notification
NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(NOTIFICATION_ID, builder.build());
}
Use pendingIntent to pass data of intent:
private void sendReminderNotification(Context context) {
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Implementation TFA")
.setContentText(body)
.setAutoCancel(true)
.setSound(notificationSound);
Intent intent = new Intent(ImpFirebaseMessagingService.this, codeActivity.class);
intent.putExtra("body", body);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
I am trying to write a simple notification code in a button that create a notification when i press on it but the notification doesn't appear when i press on the button here is the code i am using
int notificationId = 001;
// Build intent for notification content
Intent viewIntent = new Intent(SessionsActivity.this, MainActivity.class);
PendingIntent viewPendingIntent =
PendingIntent.getActivity(SessionsActivity.this, 0, viewIntent, 0);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(SessionsActivity.this)
.setContentTitle("hii")
.setContentText("hii2")
.setContentIntent(viewPendingIntent);
// Get an instance of the NotificationManager service
NotificationManagerCompat notificationManager =NotificationManagerCompat.from(SessionsActivity.this);
// Build the notification and issues it with notification manager.
notificationManager.notify(notificationId, notificationBuilder.build());
Intent viewIntent = new Intent(SessionsActivity.this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, viewIntent , PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(getResources().getString(R.string.app_name))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
notificationBuilder.setStyle(inboxStyle);
inboxStyle.setBigContentTitle("sdjshfjnds");
inboxStyle.addLine("sdjjsdfn");
notificationBuilder.setStyle(inboxStyle);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
int NOTIFICATION_ID = 100;
notificationManager.notify(NOTIFICATION_ID, notificationBuilder.build());
