As Richard said in this question > Possible to continuously update text in the notification area? , I have the same issue here .
I want to update text in the notification area .
This question is answered and accepted , but the answer doesn't help me .
It's about to create text as bitmap dynamically and set it to Small Icon of notification .
But as Richard commented , the images for setSmallIcon must be predefined in the package.There is no ability to edit them on the fly.
Please kindly show me the right way to do this stuff .
It's quite simple to update your Notification.
First of all when you create it you must create it with an id.
NotificationManager mNotificationManager =(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Sets an ID for the notification, so it can be updated
int notifyID = 1;
mNotifyBuilder = new NotificationCompat.Builder(this)
.setContentTitle("Title")
.setContentText("Text")
.setSmallIcon(R.drawable.ic_notify);
mNotificationManager.notify(
notifyID,
mNotifyBuilder.build());
Now to update your Notification you only need to notify the new notification with the old id and this will be updated (you don't need to reset the paraneter you don't want to update).
mNotifyBuilder.setContentText(setContentText("New Text")
mNotifyBuilder.setSmallIcon(R.drawable.ic_new_notify);
//this update your notification
mNotificationManager.notify(
notifyID,
mNotifyBuilder.build());
I tried to make one but it has one disadvantage is that, it has one empty notification in notification drawer,
public static int when = 0;
private void generateNotification(Context context) {
Log.i(TAG, "generateNotification");
Intent notificationIntent = new Intent(context, MainActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(
this.getApplicationContext(), 0, notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mNotification = new NotificationCompat.Builder(
this)
// .setContentTitle("AppName")
// .setContentText("Message For Notification Drawer")
// .setSound(soundUri)
// .setDefaults(Notification.DEFAULT_SOUND)
// .setVibrate(new long[] { 1000, 1000 })
// .addAction(R.drawable.ic_launcher, "View", pIntent)
// .addAction(0, "Remind", pIntent)
// .setNumber(fCount)
// .setWhen(when)
.setSmallIcon(R.drawable.ic_launcher)
.setTicker(Integer.toString(when)) // Set String you want
.setAutoCancel(true)
.setContentIntent(pIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// notificationManager.notify(when, mNotification.build());
notificationManager.notify(1, mNotification.build());
when++;
}

I have an calendar app where the info is downloaded online and there is a recyclerView of events and I want to notify the user when there is a calendar event for today, and notify with the event name or names. I have done some googling but haven't been able to figure this out.
In my MainActivity.java this is the method I created as a test from a page online
private void addNotification() {
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setSmallIcon(R.drawable.ic_check);
mBuilder.setContentTitle("Notification Alert, Click Me!");
mBuilder.setContentText("Hi, This is Android Notification Detail!");
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(contentIntent);
// Add as notification
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(0, mBuilder.build());
}
But when I call this method nothing is happening, what am I doing wrong?
I think you are missing the channel of the notification
I have a different solution, try this one (I checked it on my phone)
calling the function:
showSmallNotification(R.drawable.ic_launcher_background, "title","message");
Function code
private void showSmallNotification( int icon, String title, String message){
String CHANNEL_ID = "Channel_01";
String CHANNEL_NAME = "Notification";
// I removed one of the semi-colons in the next line of code
NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
inboxStyle.addLine(message);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
// I would suggest that you use IMPORTANCE_DEFAULT instead of IMPORTANCE_HIGH
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
channel.enableVibration(true);
channel.setLightColor(Color.BLUE);
channel.enableLights(true);
//channel.canShowBadge();
// Did you mean to set the property to enable Show Badge?
channel.setShowBadge(true);
notificationManager.createNotificationChannel(channel);
}
Intent mainIntent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, mainIntent, 0);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(getApplicationContext(), CHANNEL_ID)
.setVibrate(new long[]{0, 100})
.setPriority(Notification.PRIORITY_MAX)
.setLights(Color.BLUE, 3000, 3000)
.setAutoCancel(true)
.setContentTitle(title)
.setContentIntent(pendingIntent)
.setSmallIcon(R.mipmap.ic_launcher)
.setStyle(inboxStyle)
.setContentText(message);
// Don't forget to set the ChannelID!!
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
notificationBuilder.setChannelId(CHANNEL_ID);
}
notificationManager.notify(CHANNEL_ID, 1, notificationBuilder.build());
}
Edit
In order to check if there are any events every day you will need to use AlarmManager as from it's name you can schedule an event every day
You can see a solution (or at least it will give a direction) once you did that I think the next step would be to send the intent to a service which will check if there are any events available in current day. If there are any just show the notification/s
alarm manager link
i have a notification manager that launches an activity when clicked.
mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setOngoing(true)
.setOnlyAlertOnce(true)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setContent(remoteViews)
.setAutoCancel(false);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, new Intent(context, Launch.class).putExtra("type", 0), 0);
mBuilder.setContentIntent(pendingIntent);
the function performed in this can also be be asynchronous depending on the users preference. I want to update the notification to an ongoing progress. something of this nature:
mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setOngoing(true)
.setContentTitle("Sending details")
.setPriority(NotificationCompat.PRIORITY_MAX)
.setProgress(100, 0, true)
.setOnlyAlertOnce(true)
.setAutoCancel(false);
when the notification is selected. This is achieved but what i want to do is update the notification from the former to the later without having to first slide up the navigation drawer.
Try this..
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
you need NOTIFICATION_ID to updated the specific notification.
Please refer this
I am trying to modify existing notifications in android.
What I have in my app
When a notification is already in system tray and another notification appears, the second one overwrites the first notification content.
What I am looking for
If second Notification arrives then instead of overwriting the first I need to change title to show 2 New Messages and go on incrementing as notifications arrive.
Code Implemented
Bitmap icon = BitmapFactory.decodeResource(ctx.getResources(),
R.drawable.icon);
Intent launchActivity = new Intent(ctx, CordovaApp.class);
launchActivity.putExtra("heading",newsHeader);
launchActivity.putExtra("content",newsText);
PendingIntent pi = PendingIntent.getActivity(ctx,0, launchActivity, PendingIntent.FLAG_NO_CREATE);
ParseAnalytics.trackAppOpened(launchActivity);
if(pi==null){
Log.d(TAG, "Pending Intenet is null.");
}else{
Log.d(TAG, "Pending Intenet is not null.");
}
Notification noti = new NotificationCompat.Builder(ctx)
.setContentTitle(newsHeader)
.setContentText(newsText)
.setSmallIcon(R.drawable.icon)
.setLargeIcon(icon)
.setContentIntent(pi)
.setAutoCancel(true)
.build();
NotificationManager nm = (NotificationManager)ctx.getSystemService(Context.NOTIFICATION_SERVICE);
nm.notify(0, noti);
Update
I implemented the solution mentioned below by #yogendra and now I am getting two separate notifications. Instead of getting stacked. Below is updated code
Notification noti = new NotificationCompat.Builder(ctx)
.setContentTitle(newsHeader)
.setContentText(newsText)
.setSmallIcon(R.drawable.icon)
.setGroup(GROUP_KEY_EMAILS)
.setLargeIcon(icon)
.setContentIntent(pi)
.setLights(Color.parseColor("green"), 5000, 5000)
.setAutoCancel(true)
.setPriority(2)
.setTicker("Notification from App")
.setGroupSummary(true)
.build();
NotificationManager nm = (NotificationManager)ctx.getSystemService(Context.NOTIFICATION_SERVICE);
int timeSeconds = (int)System.currentTimeMillis()%Integer.MAX_VALUE;
Log.i(TAG,"Timing function called "+timeSeconds);
nm.notify(timeSeconds, noti);
See your code
nm.notify(0, noti);
where
notify(int id, Notification notification)
Here 0 is the ID of notification which is to be managed with respect to each notification. If you want to show a different notification your notification id should be unique each time. If you try to post a notification with the same notification id your previously displayed notification will be replaced with the latest notification.
Solution
Now you need to display a custom notification with a custom layout and update the counter each time .
Source code to create a Custom Notification.
create global variable in your class :
private int count = 0;
private ArrayList<String> notificationList = new ArrayList<String>();
private String GROUP_KEY_EMAILS = "email";
/call method createNotification when you need to create notification and pass message what you need to show on message./
private void createNotification(String notificationMassage) {
notificationList.add(notificationMassage);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Bitmap largeIcon = BitmapFactory.decodeResource(getResources(),
R.drawable.ic_launcher);
// Create builder
Builder summaryNotification = new NotificationCompat.Builder(this)
.setContentTitle(notificationList.size()+" new messages")
.setSmallIcon(R.drawable.settings)
.setLargeIcon(largeIcon)
.setGroup(GROUP_KEY_EMAILS)
.setGroupSummary(true)
.setAutoCancel(true);
// Create style
InboxStyle nStyle = new NotificationCompat.InboxStyle();
nStyle.setBigContentTitle(notificationList.size()+" new messages");
nStyle.setSummaryText("Summery Text...<you can set as blank>");
for (String Str : notificationList) {
nStyle.addLine(Str);
}
summaryNotification.setStyle(nStyle);
mNotificationManager.notify(0, summaryNotification.build());
count++;
}
/**
please clear notification array list after tap on notification.

I followed this Sample Code
In Big Text Notifications section, he said that need expand to see Big text notification form, as image im below :
I wonder that we can not set Expanded Notification as default in Big Text Notifications?
People who know it is can or not,
If can,
Please tell me how to do it,
Thanks,
The documentation states:
A notification's big view appears only when the notification is
expanded, which happens when the notification is at the top of the
notification drawer, or when the user expands the notification with a
gesture.
So my answer is no, you can't expand it by default.
There is however a trick to push the notification to the top of the list where it would be expanded. Simply set the Priority to Notification.PRIORITY_MAX and chances are that your app's notification will make it to the top.
Notification noti = new Notification.Builder()
... // The same notification properties as the others
.setStyle(new Notification.BigPictureStyle().bigPicture(mBitmap))
.build();
You change
.setStyle(new NotificationCompat.BigTextStyle().bigText(th_alert))
along with the announcement
notification = new NotificationCompat.Builder(context)
Here is an example:
You can set Code
Intent intent = new Intent(context, ReserveStatusActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
intent = new Intent(String.valueOf(PushActivity.class));
intent.putExtra("message", MESSAGE);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(PushActivity.class);
stackBuilder.addNextIntent(intent);
// PendingIntent pendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
// android.support.v4.app.NotificationCompat.BigTextStyle bigStyle = new NotificationCompat.BigTextStyle();
// bigStyle.bigText((CharSequence) context);
notification = new NotificationCompat.Builder(context)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(th_title)
.setContentText(th_alert)
.setAutoCancel(true)
// .setStyle(new Notification.BigTextStyle().bigText(th_alert) ตัวเก่า
// .setStyle(new NotificationCompat.BigTextStyle().bigText(th_title))
.setStyle(new NotificationCompat.BigTextStyle().bigText(th_alert))
.setContentIntent(pendingIntent)
.setNumber(++numMessages)
.build();
notification.sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notificationManager.notify(1000, notification);
notificationBuilder.setStyle(new NotificationCompat.BigTextStyle().bigText("Your Long Text here"))
simply setStyle of your notification builder.
No need of doing any kind of modification in the any file for showing of multiple lines of Notification while using Push Notification V5, remove the field "style", from the object you are sending. Automatically the Multiple lines of notification will be seen. For more information, upvote the answer, ask your query. I will help you out.

From this notification code you have got images, and big text or more.
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
mBuilder.setSmallIcon(R.drawable.small_logo);
mBuilder.setColor(Color.parseColor("#D74F4F"));
} else {
mBuilder.setSmallIcon(icon);
}
mBuilder.setTicker(title).setWhen(when);
mBuilder.setAutoCancel(true);
mBuilder.setContentTitle(title);
mBuilder.setContentIntent(intent);
mBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
mBuilder.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), icon));
mBuilder.setContentText(msg);
mBuilder.setPriority(Notification.PRIORITY_MAX);
if (Utils.validateString(banner_path)) {
mBuilder.setStyle(notiStyle);
} else {
mBuilder.setStyle(new NotificationCompat.BigTextStyle().bigText(msg));
}
Notification noti = mBuilder.build();
notificationManager.notify(0, noti);
i found many answer to this, but none help :(
I have this code:
private static void generateNotification(Context context, String message) {
int icon = R.drawable.icon;
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
int notifyID = 96;
NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(context)
.setContentTitle("MyApp")
.setContentText(message)
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setSmallIcon(icon);
Notification notification = mNotifyBuilder.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
mNotificationManager.notify(notifyID, notification);
}
But if i click on notification nothing happen and it is still there. In documentation is, that i need to use:
.setAutoCancel(true)
Some one have similar problem and somebody tells him to use:
notification.flags |= Notification.FLAG_AUTO_CANCEL;
I use both, but no result :(
Thank you very much for answers. :)
I think that if you don't use an Intent with your notification, the only way to dismiss its to swipe it.
Otherwise you can use an Intent to open your activity and that will actually clear the notification:
Intent showIntent = new Intent(this, YourActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, showIntent, 0);
And to add it to the notification:
NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(context)
.setContentTitle("MyApp")
.setContentText(message)
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setContentIntent(contentIntent)
.setSmallIcon(icon);
Hope this helps!
The user can dismiss all notification or if you set your notification to auto-cancel it is also removed once the user selects it.
You can also call the cancel() for a specific notification ID on the NotificationManager. The cancelAll() method call removes all of the notifications you previously issued.
Example:
mNotificationManager.cancel(notifyId);
just use this line inside button onclick event-
mNotificationManager.cancel(notifyId);//id is that u used for notification
just add
Intent showIntent = new Intent();
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, showIntent, 0);
myNotification = new Notification.Builder(getApplicationContext())
.setContentTitle("Title")
.setContentText("Text")
.setTicker("notificatio")
.setContentIntent(contentIntent)
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setSmallIcon(R.drawable.ic_launcher)
.build();
add empty pending intent then on click on notification, notification will remove. it works for me.
I generally use:
mNotificationManager.cancelAll();
