Remove notification on clicking (Not a duplicate) [duplicate]

I just started working with notifications and now I'm trying to remove the notification and launch the app once the notification has been tapped in the notificationcenter.
I tried to work with the following code:
import android.app.NotificationManager;
public class ExpandNotification {
private int NOTIFICATION = 546;
private NotificationManager mNM;
public void onCreate() {
mNM.cancel(NOTIFICATION);
setContentView(R.layout.activity_on);
//Toast.makeText(this, "stopped service", Toast.LENGTH_SHORT).show();
}
I think this code executes the other class when tapped?
PendingIntent contentIntent = PendingIntent.getActivity(this, REQUEST_CODE, new Intent(this, ExpandNotification.class), 0);
However the notification doesn't go away, nor does the application launch.
But I'm able to swipe it to left or right to remove it but that's not what I want..

To get the same effect using Notification.Builder or NotificationCompat.Builder call setAutoCancel(true) on the Builder instance.

Use the flag Notification.FLAG_AUTO_CANCEL
Notification notification = new Notification(icon, tickerText, when);
notification.setLatestEventInfo(context, contentTitle, contentText, pendingIntent);
// Cancel the notification after its selected
notification.flags |= Notification.FLAG_AUTO_CANCEL;
and to launch the app:
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// Create a new intent which will be fired if you click on the notification
Intent intent = new Intent(context, App.class);
// Attach the intent to a pending intent
PendingIntent pendingIntent = PendingIntent.getActivity(context, intent_id, intent, PendingIntent.FLAG_UPDATE_CURRENT);

This answer is too much late but specially i write following solution because notification constructor become deprecated so use notification using builder , like following :
**.setAutoCancel(true)** is used to remove notification on click
and entire notification is like follwoing :
private void makeNotification(String title,String msg){
Intent resultIntent = new Intent(this, MasterActivity.class);
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
this,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setContentIntent(resultPendingIntent)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(title)
.setAutoCancel(true)
.setContentText(msg);
int mNotificationId = 001;
NotificationManager mNotifyMgr =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
mNotifyMgr.notify(mNotificationId, mBuilder.build());
}
Calling this method with title and message you get perfect notification.

You can directly add .setAutoCancel(true) this line into your code in order to remove notification on click.
This must be added in your builder variable.
Example:
mBuilder = new NotificationCompat.Builder(mContext);
mBuilder.setSmallIcon(R.mipmap.ic_launcher);
mBuilder.setContentTitle("Notification")
.setContentText("Hello")
.setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
.setAutoCancel(true)
.setContentIntent(pendingIntent);

Best & simple way is set builder.setAutoCancel(true) it's cancel your notification after clicking on notification. I hope this code help you.
Builder for notification
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(android.R.drawable.btn_star);
builder.setContentTitle("This is title of notification");
builder.setContentText("This is a notification Text");
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
For open an activity on clicking notification
Intent intent = new Intent(Broadcastdemo.this, ThreadDemo.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 113,intent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
Show bulder in notification
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(114, builder.build());
Complete code for show a notification with icon, image, title, description, auto cancel and on click open an activity
public void ShowIntentNotification(View v)
{
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(android.R.drawable.btn_star);
builder.setContentTitle("This is title of notification");
builder.setContentText("This is a notification Text");
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
Intent intent = new Intent(Broadcastdemo.this, ThreadDemo.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 113,intent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(114, builder.build());
}

For my it was that
.setPriority(Notification.PRIORITY_HIGH);
that was causing the notification to not clear after click... make sure you use:
.setPriority(Notification.PRIORITY_DEFAULT);
And .setAutoCancel(true) should work.

Preview Notification on android

I'm using this code to show a notification to user from code :
Intent intent = new Intent(this, this.getClass());
PendingIntent pi = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.icon)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.icon))
.setContentTitle("Notification!")
.setContentText("Hello word")
.setContentIntent(pi)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setPriority(NotificationCompat.PRIORITY_MAX);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, mBuilder.build());
This is juste adding the notification in the notification screen (and also the icon of my appliaction in the status bar)
But how can I have a preview of this notification on top of screen ?

How create Android different notification every time?

Notification work normally one problem is All notification go to last notification link. How can I fix it? Every notification go to it's own link. Every message notification go to he's/she's inbox. How can I do that?
Intent intent_activity_start = new Intent(this,MainActivity.class);
intent_activity_start.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent_activity_start.putExtra("links", c.getString("link"));
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent_activity_start,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(R.drawable.logo);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
builder.setLargeIcon(getCircleBitmap(photoStream(c.getString("profile_photo"))));
builder.setContentTitle("Title");
builder.setContentText(c.getString("notify"));
builder.setSound(notificationSound);
builder.setStyle(new NotificationCompat.BigTextStyle()
.bigText(c.getString("notify")));
if(!c.getString("photo").equals("null")){
builder.setStyle(new NotificationCompat.BigPictureStyle()
.bigPicture(photoStream(c.getString("photo"))));
}
NotificationManager notificationManager = (NotificationManager) getSystemService(
NOTIFICATION_SERVICE);
notificationManager.notify(counter.incrementAndGet(), builder.build());

android notification click not working

I am using this code inside a service in order to get a notification if I have any new alerts but when I click on them I'm not getting to the view that I want:
if(newAlertCounter > 0) // alert user about new alerts
{
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_action_warning)
.setContentTitle(newAlertCounter + " new flood alerts!")
.setContentText("Tap to see where in your vecinity.");
// Sets an ID for the notification
int mNotificationId = 001;
// Gets an instance of the NotificationManager service
NotificationManager mNotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Builds the notification and issues it.
mNotifyMgr.notify(mNotificationId, mBuilder.build());
// notification click action
Intent notificationIntent = new Intent(this, ViewAlertsActivity.class);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
}
It shows up but its not clickable, so whats wrong with this?

put
mNotifyMgr.notify(mNotificationId, mBuilder.build());
after
mBuilder.setContentIntent(resultPendingIntent);

Move your
mNotifyMgr.notify(mNotificationId, mBuilder.build());
after
mBuilder.setContentIntent(resultPendingIntent);
When you call .build() you create the notification without the content intent. (and no, it will not be added after because the object which will be sent to notification system will be the Notification not the Builder)
if(newAlertCounter > 0) // alert user about new alerts
{
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_action_warning)
.setContentTitle(newAlertCounter + " new flood alerts!")
.setContentText("Tap to see where in your vecinity.");
// Sets an ID for the notification
int mNotificationId = 001;
// Gets an instance of the NotificationManager service
NotificationManager mNotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Builds the notification and issues it.
// notification click action
Intent notificationIntent = new Intent(this, ViewAlertsActivity.class);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
mNotifyMgr.notify(mNotificationId, mBuilder.build());
}

Close Notification on Selection of GCM Notification Android

I want to close the notification when the user selects the notification.This is my code that i am using to show the notification to the user.I am using this in GCM (Google Cloud Messaging)
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
new Intent(this, DemoActivity.class), 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_stat_gcm)
.setContentTitle(" Notification")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(msg))
.setContentText(msg.toString());
mBuilder.build().flags = Notification.FLAG_AUTO_CANCEL;
Uri notificationSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
mBuilder.setSound(notificationSound);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
But this is not working fine for me when i am selecting the notification it is opening the activity but it is not closing the notifications .Please suggest me what went wrong in this

Try
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.cancel(NOTIFICATION_ID); // use this to cancel notification
Or you can try
mBuilder.setAutoCancel(true); //so the notification is automatically canceled when the user clicks it in the panel

Just remove these lines :
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
new Intent(this, DemoActivity.class), 0);
And
mBuilder.setContentIntent(contentIntent);

Use setAutoCancel (boolean autoCancel)
Setting this flag will make it so the notification is automatically canceled when the user clicks it in the panel. The PendingIntent set with setDeleteIntent(PendingIntent) will be broadcast when the notification is canceled.
Reference:
http://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#setAutoCancel(boolean)

Notification notification = new Notification(
YOUR_DRAWABLE_RESOURCE, "Message",
System.currentTimeMillis());
notification.flags = Notification.FLAG_AUTO_CANCEL;
You can use the FLAG_AUTO_CANCEL to cancel notfication when selected.
