How to dismiss full screen intent to notification bar?

I am trying to display a notification about incoming call (from within my app) to a user. I found out that I can use NotificationCompat.Builder.setFullScreenIntent() to make a notification persistent on the top of the screen when application is running in the background.
However now when user does not answer the call and other party stops ringing how do I make that full screen intent disappear and show it inside a notification bar?
The only way I can think of is calling cancel() on that notification ID and creating a new one without full screen intent. But is this a good way of doing this? Is there a 'good practice' on how to achieve what I want?
Snippet showing how I create the notification:
public void displayNotification(String title, String text, int conversationId) {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
this.createNotificationChannel();
Intent intent = new Intent(context, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this.context, 0, intent, PendingIntent.FLAG_IMMUTABLE);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this.context, this.channelID);
builder.setContentTitle(title);
builder.setContentText(text);
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setFullScreenIntent(pendingIntent, true);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this.context);
notificationManager.notify(conversationId, builder.build());
}

my notification code suddenly stopped working

I have an notification that works fine yesterday, the notification not appears and I don't remember I had touched the code..
that notification must be appears when I get the desired value and must open a pop up dialog we user touch it.
can anyone help please?
the notification code - in side service-:
Intent notifyIntent = new Intent(context.getApplicationContext(), PopUp.class);
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//how I tried to pass data
notifyIntent.putExtra("text1", text1);
notifyIntent.putExtra("text2", text2);
PendingIntent pIntent = PendingIntent.getActivity(context, 1, notifyIntent, 0);
// build notification
// the addAction re-use the same intent to keep the example short
Notification n = new NotificationCompat.Builder(context,CHANNEL_ID2)
.setContentTitle("check this")
.setSmallIcon(R.drawable.ic_delete)
.setContentIntent(pIntent)
.build();
NotificationManager notificationManager =(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, n);
I'm using android studio emulator API 30
in the same service class I have a Notification and it is appearing to indicate that the service is working in the background, except the Notification that I but its code above it is not working suddenly
I don't know what is the problem, please help

When Issuing the notification with notify the notificationId must be a unique int for each notification. Update your code to include a random unique notificationId
see below
//you can use the timestamp
int notificationId = Integer.parseInt(String.valueOf(System.currentTimeMillis()));
NotificationManager notificationManager =(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
// notificationId is a unique int for each notification that you must define
notificationManager.notify(notificationId, n);
Android Create a Notification

Action icon added in notification not showing up

I am trying to create a notification for Incoming call. For that I have added two actions in notification. My action text only is displayed.Action icon is not displayed in notification.
I want to add icon near Answer and cancel which I added as AddAction in Notification. I have added action icon like below,
NotificationCompat.Action answerAction = new NotificationCompat.Action.Builder(R.drawable.answer_call_icon, "Answer", pendingIntent).build();
NotificationCompat.Action cancelAction = new NotificationCompat.Action.Builder(R.drawable.cancel, "Cancel", pendingIntent).build();
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
.setLargeIcon((BitmapFactory.decodeResource(getResources(), R.drawable.call_logo)))
.setContentTitle(intent.getStringExtra("Number"))
.setSmallIcon(R.drawable.call_logo)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.setFullScreenIntent(pendingIntent, true)
.setCategory(NotificationCompat.CATEGORY_CALL)
.addAction(answerAction)
.addAction(cancelAction)
.setPriority(NotificationCompat.PRIORITY_HIGH);
NotificationManagerCompat nManager = NotificationManagerCompat.from(this);
nManager.notify(2,builder.build());
One more query,
Below is my notification channnel,
NotificationChannel chan = new NotificationChannel(NOTIFICATION_CHANNEL_ID, channelName, NotificationManager.IMPORTANCE_HIGH);
chan.setLightColor(Color.BLUE);
chan.setLockscreenVisibility(Notification.FLAG_FOREGROUND_SERVICE);
chan.setImportance(NotificationManager.IMPORTANCE_HIGH);
chan.setSound(defaultRingToneUri,audioAttributes);
chan.enableLights(true);
chan.shouldShowLights();
chan.setVibrationPattern(vibrate);
chan.enableVibration(true);
Context context=getApplicationContext();
NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
assert manager != null;
manager.createNotificationChannel(chan);
Not able to get ringtone while receiving notification. Is the way Im setting sound is right??
Anybody please help me to solve this...
Posted 2 days ago..but till now not able to find solution.

As per the Notifications in Android N blog post:
Notification actions have also received a redesign and are now in a visually separate bar below the notification.
You’ll note that the icons are not present in the new notifications; instead more room is provided for the labels themselves in the constrained space of the notification shade. However, the notification action icons are still required and continue to be used on older versions of Android and on devices such as Android Wear.
So it is expected that you do not see the icons associated with notification actions.

If you need more flexibility in creating the notification layout, go for the custom one.
Ref: https://developer.android.com/training/notify-user/custom-notification
Use the Drawable left/right option to set an icon with text in the button.
// Get the layouts to use in the custom notification
RemoteViews notificationLayout = new RemoteViews(getPackageName(), R.layout.notification_small);
RemoteViews notificationLayoutExpanded = new RemoteViews(getPackageName(), R.layout.notification_large);
// Apply the layouts to the notification
Notification customNotification = new NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(R.drawable.notification_icon)
.setStyle(new NotificationCompat.DecoratedCustomViewStyle())
.setCustomContentView(notificationLayout)
.setCustomBigContentView(notificationLayoutExpanded)
.build();

As I understand: you have a problem with your notification you can use this method :
private void showSmallNotification(NotificationCompat.Builder mBuilder, int icon, String title, String message, String timeStamp, PendingIntent resultPendingIntent, Uri alarmSound) {
NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
inboxStyle.addLine(message);
Notification notification;
notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
.setAutoCancel(true)
.setContentTitle(title)
.setContentIntent(resultPendingIntent)
.setSound(alarmSound)
.setStyle(inboxStyle)
.setWhen(getTimeMilliSec(timeStamp))
.setContentText(message)
.build();
NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(Constant.NOTIFICATION_ID, notification);
}
or this one :
private void showBigNotification(Bitmap bitmap, NotificationCompat.Builder mBuilder, int icon, String title, String message, String timeStamp, PendingIntent resultPendingIntent, Uri alarmSound) {
NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle();
bigPictureStyle.setBigContentTitle(title);
bigPictureStyle.setSummaryText(Html.fromHtml(message).toString());
bigPictureStyle.bigPicture(bitmap);
Notification notification;
notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
.setAutoCancel(true)
.setContentTitle(title)
.setContentIntent(resultPendingIntent)
.setSound(alarmSound)
.setStyle(bigPictureStyle)
.setWhen(getTimeMilliSec(timeStamp))
.setContentText(message)
.build();
NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(Constant.NOTIFICATION_ID_BIG_IMAGE, notification);
}

To play ringtone you can make use of android mediaplayer as shown below:
Var _mediaPlayer = MediaPlayer.Create(this,
Android.Provider.Settings.System.DefaultRingtoneUri);
_mediaPlayer.Start();
Task.Delay(60 * 1000).ContinueWith(t => _mediaPlayer?.Stop()); //stop after 60sec
You can take the global instance of _mediaPlayer and stop this as per user interaction with notification.
This is the c# xamarin android example, you can use the same class with java syntax.

How do I get the program to display multiple notifications on the screen?

i cant seem to understand how to display multiple notifications without one overlaying another. In my case it only displays one at the time.
picture 1
My goal is to get it to work like on the screenshot below
picture 2
What should I change or maybe add to my code?
chunk of code assigned for notifications
#Override
protected void onPostExecute(Bitmap result) {
super.onPostExecute(result);
Intent intent = new Intent(ctx, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("com.example.romanchuk.appisode.notifyId", id);
intent.putExtra("com.example.romanchuk.appisode.show_id", show_id);
PendingIntent pendingIntent = PendingIntent.getActivity(ctx, sNotificationId /* Request code */, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
inboxStyle.addLine(message);
NotificationCompat.BigTextStyle bigText = new NotificationCompat.BigTextStyle();
bigText.bigText(message);
bigText.setBigContentTitle(getString(R.string.app_name));
NotificationCompat.Builder builder = new NotificationCompat.Builder(ctx);
Notification notification = null;
notification = builder.setSmallIcon(R.mipmap.ic_launcher).setTicker(title).setWhen(0)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
.setColor(getResources().getColor(R.color.color_accent))
.setContentTitle("Appisode")
.setContentIntent(pendingIntent)
.setFullScreenIntent(pendingIntent, true)
.setContentText(message)
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setStyle(inboxStyle)
.setSmallIcon(R.drawable.small_icon)
.setSound(defaultSoundUri).build();
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(sNotificationId++, notification);
}

If you want to show multiple notifications, You Notification id should be different, If the notification id already exists in the notifications it will override that notification.
notificationManager.notify(sNotificationId++, notification);
In this sNotificationId should be different for all notification
If your id or show_id is int and not constant and if it will be different for each notification you can use that also as notification id.
Or try to give different tag for each notification like this,
notificationManager.notify(String.valueOf(System.currentTimeMillis()), sNotificationId++, notification);

Android: Using AUTO-CANCEL on a notification when your app is running in the background

I have looked at all the other AUTO-CANCEL-not-working questions here, and they all seem to involve mistakes that I am not making. I have tried both
builder.setAutoCancel(true);
and
Notification notif = builder.build();
notif.flags |= Notification.FLAG_AUTO_CANCEL;
Neither works.
I am using NotificationCompat since my minimum API is 8. Here is my full code. In this particular notification, I am not calling an intent, since I don't need the user to do anything.
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentTitle(getString(R.string.app_name) + ": my title");
builder.setContentText(message);
builder.setSmallIcon(R.drawable.notification_icon);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.prog_icon);
builder.setLargeIcon(bitmap);
builder.setAutoCancel(true); // dismiss notification on user click
NotificationManager notiManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
notiManager.notify(MY_NOTI_MANAGER_ID, builder.build());
The notification displays just perfectly. You can swipe to clear it. But simply tapping it does not dismiss the notification. It just lights up and stay there.
Some possible differences between my code and others' posted here:
1) I am using NotificationCompat (which should not make a difference, but we've heard that before).
2) Since my notification is simple, I do not attach an intent.
Please let me know if you have any insights.
Edit: My purpose is to dismiss a notification without foregrounding my background app.

So apparently you do need a pending intent.
At Android - notification manager, having a notification without an intent, I found a solution that grabs the current active application as your pending intent (so that you don't have to start your own activity in order to dismiss the notification).
I just added the following two lines of code (right after setting the auto-cancel):
PendingIntent notifyPIntent =
PendingIntent.getActivity(getApplicationContext(), 0, new Intent(), 0);
builder.setContentIntent(notifyPIntent);
It worked great. I would say that if you don't want your activity to restart as a result of the user clicking your notification, then this is your best option.

You appear to be missing the PendingIntent and setContentIntent() call. I believe that is required for auto-cancel to work.
Here is some Notification-displaying logic from this sample project that works:
private void raiseNotification(Intent inbound, File output, Exception e) {
NotificationCompat.Builder b=new NotificationCompat.Builder(this);
b.setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL)
.setWhen(System.currentTimeMillis());
if (e == null) {
b.setContentTitle(getString(R.string.download_complete))
.setContentText(getString(R.string.fun))
.setSmallIcon(android.R.drawable.stat_sys_download_done)
.setTicker(getString(R.string.download_complete));
Intent outbound=new Intent(Intent.ACTION_VIEW);
outbound.setDataAndType(Uri.fromFile(output), inbound.getType());
b.setContentIntent(PendingIntent.getActivity(this, 0, outbound, 0));
}
else {
b.setContentTitle(getString(R.string.exception))
.setContentText(e.getMessage())
.setSmallIcon(android.R.drawable.stat_notify_error)
.setTicker(getString(R.string.exception));
}
NotificationManager mgr=
(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
mgr.notify(NOTIFY_ID, b.build());
}

Hai dear friend if you want to show non cancelable
notification(not cancelable for users) for a particular
time and after that you need clear it (like the music player) you can use this.
mNotificationBuilder .setSmallIcon(android.R.drawable.btn_plus);
mNotificationBuilder .setContentTitle("My notification");
mNotificationBuilder .setContentText("Notificattion From service");
mNotificationBuilder .setLights(0xFF0000FF, 500, 500);
Notification note = mNotificationBuilder.build();
note.flags = Notification.FLAG_ONGOING_EVENT; // For Non cancellable notification
mNotificationManager.notify(NOTIFICATION_ID, note);
