Remove Notification from Notification area once it is clicked - android

I am displaying a notification whenever a new message is received that contains particular keywords. I have used following code to show the notification in the notification area,
String contentTitle = "V-Card Received";
String contentText = "You have reeived a new V-Card";
mNotificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(context, receiveVCard.class);
notificationIntent.putExtra("sender", sender);
notificationIntent.putExtra("vCardString", messages[i].getDisplayMessageBody());
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, notificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK);
int icon = R.drawable.contactvcard;
CharSequence tickerText = "V-Card Received";
long when = System.currentTimeMillis();
notifyDetails = new Notification(icon, tickerText, when);
notifyDetails.setLatestEventInfo(context, contentTitle, contentText, pendingIntent);
mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails);
notifyDetails.flags =Notification.DEFAULT_LIGHTS | Notification.FLAG_AUTO_CANCEL;
Now I want to remove the notification once the user clicks on it. I Have used Notification.FLAG_AUTO_CANCEL to cancel the notification. But it is not removing the notification even if the user clicks on it. Is there any other way to remove the notification, when the user clicks on the notification.

You are basically setting flags after notification has been put.
You need to swap the last two lines of the code you have provided. Set flags before calling nm.notify();

try this it works fine for me
--> notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0,notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
--> notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(i, notification);

this is the prototype of the notification i used in one of my app
Notification notification=new Notification(R.drawable.ic_stat_download_interrupted,getResources().getString(R.string.dint),System.currentTimeMillis());
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.notification_download_complete);
contentView.setImageViewResource(R.id.notimage, R.drawable.ic_stat_download_interrupted);
contentView.setTextViewText(R.id.nottext, getResources().getString(R.string.dint));
contentView.setTextViewText(R.id.nottitle, update.initialDetail.fileName);
notification.contentView = contentView;
notification.flags=Notification.FLAG_AUTO_CANCEL;
Intent notificationIntent = new Intent(getApplicationContext(), MainDashboard.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
notificationIntent.putExtra(EXTRA_NOTIFICATION_SHOW_DOWNLOADS, true);
PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(),0,notificationIntent, 0);
notification.contentIntent=contentIntent;
nm.notify(update.updateId.intValue(), notification);

its working for me
notifyDetails.flags =Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_AUTO_CANCEL;
Hope this is helpful for you.

Clear all stack when notification is clicked

I'm showing a notification using FCM on my android app. Everything is working as expected except one issue.
When user clicks on the notification, I need to close all background and foreground activities of my app and open the intent specified in the notification.
How can I do it?
I'm using pending intent like this
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
final PendingIntent resultPendingIntent =
PendingIntent.getActivity(
mContext,
0,
intent,
PendingIntent.FLAG_CANCEL_CURRENT
);
YOu can use 2 flags to clear all stacks
intentToLaunch.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intentToLaunch.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Try this,
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
Intent notificationIntent = new Intent(context, HomeActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);

values for the intent remain the updated one when making multiple notification for push notification

I am making an app which requires me to send multiple push notifications to users which has distinct values which will be shows when user click on them from status bar.
I am making the intent using the below code
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification();
notification.when = when;
notification.icon = icon;
Intent notificationIntent = new Intent(context,RecentStoryPage.class);
notificationIntent.putExtra("id", id_leader);
notificationIntent.putExtra("title", title);
notificationIntent.putExtra("message", message);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(context, title, "", intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(Integer.parseInt(id), notification);
When I send single notification, this does not make any issues however whenever I make multiple notifications, whichever notification I click on, it always opens with the recent value.
I got my mistake, I made this line error full
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
which I should have made to
PendingIntent intent = PendingIntent.getActivity(context, Integer.parseInt(id), notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

How to blink notification icon in android? [DONE]

notificationManager.notify(NOTIFICATION, notification);
i found solution :i created animation file and set that file , thanks i found solution
SET FILE name here:-
int icon = R.drawable.animationfile;
long when = System.currentTimeMillis();
notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, "Your location is tracing", when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, Home.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, "Rohit", intent);
//notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.flags |= Notification.FLAG_NO_CLEAR;
notification.defaults = Notification.DEFAULT_ALL;
notificationManager.notify(NOTIFICATION, notification);
i created this file
animationfile.xml :
<animation-list
xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false">
<item android:drawable="#drawable/icaon" android:duration="10000" />
<item android:drawable="#drawable/icon" android:duration="10000" />
</animation-list>
To show the upload or download notification like the default one which we have in android (an up or down arrow moving up or down respectively like this , till the upload or download is completed), simply use the below.
Set your notification builder to,
mBuilder.setSmallIcon(android.R.drawable.stat_sys_download);
mBuilder.setTicker(mContext.getString(R.string.notification_ticker)); //Pass an empty string if you dont want any text to appear on the status bar
//Call notify() method of notification manager to see the effect
And when you want the animated icon to stop after the upload or download is completed use below,
mBuilder.setSmallIcon(R.drawable.ic_download); //ic_download is similar looking icon in your drawable folder
mNotifyManager.notify(0, mBuilder.build());
Hope this helps. :)

Android:Notification starts new activity instead of resuming old one if originally activity is not started from launcher

I have spent a week to find a solution but with no success, so I need a help.
When my application goes to background then notification appears and displays status of activity.
It works perfectly if the application is started from launcher (with action = android.intent.action.MAIN and category = android.intent.category.LAUNCHER).
But if the application is started f.e. from the gallery using action android.intent.action.SEND or android.intent.action.SEND_MULTIPLE and category android.intent.category.DEFAULT, then notification starts new activity instead of resuming existing one.
The code for notification:
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager notificationManager = (NotificationManager) getSystemService(ns);
int icon = R.drawable.icon;
Notification notification = new Notification(icon, null, 0);
notification.flags |= Notification.FLAG_ONGOING_EVENT|Notification.FLAG_AUTO_CANCEL|Notification.FLAG_ONLY_ALERT_ONCE;
Context context = this.getApplicationContext();
CharSequence contentTitle = "XXX";
CharSequence contentText = "XXX";
Intent notificationIntent = new Intent(context, MyClass.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent activityIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, contentTitle, contentText, activityIntent);
notificationManager.notify(NOTIFICATION_ID, notification);
In other words, I have an application "My Application" with activity "My Activity". If "My Activity" is started on the top of gallery and creates notification, then after pressing the notification "My application" is started instead of resuming the gallery with "My activity".
Do you have any idea how to heal it?
Intent myIntent = new Intent(this, MainActivity.class);
myIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(
getBaseContext(), 0, myIntent,
PendingIntent.FLAG_CANCEL_CURRENT);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notification.flags = notification.flags
| Notification.FLAG_ONGOING_EVENT;
notification.flags |= Notification.FLAG_NO_CLEAR;

Android notification click

a notification pops up when I get a new task. On click on that notification, it goes to TestExList.java activity.
private void createNewTaskNotification(String s, String id) {
CharSequence title = "TASK";
CharSequence message = s;
notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.checkyes, s,
System.currentTimeMillis());
notification.flags = Notification.FLAG_AUTO_CANCEL;
notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_VIBRATE;
Intent notificationIntent = new Intent(context, TestExList.class);
notificationIntent.putExtra("EmpID", Functions.getLoginEmpID(context));
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP );
PendingIntent pendingIntent = PendingIntent.getActivity(context,
Integer.parseInt(id), notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(context, title, message, pendingIntent);
notificationManager.notify(Integer.parseInt(id), notification);
}
The way it's working is, if i am on another screen, click on notification takes me to TestExList.java.
If i am on the same screen(TestExList.java), it is NOT loading that page aagain. I would like to refresh that page so that I can see my new task on that page.
what am I doing wrong ?
remove this line
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP );
this line pops up the activity from activity stack if activity exists, otherwise creates a new instance of the activity, hope this helps.
