android push notification not removed when i swipe

android push notification not removed when i swipe
following is my code that i trying to implement push notification
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(icon)
.setContentTitle(title)
.setAutoCancel(true)
.setContentText(message)
.setOngoing(true);
Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.putExtra("Your Message", message);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
notificationIntent.putExtra("type", type);
notificationIntent.putExtra("id", id);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(intent);
notificationManager.notify(NOTIFICATION_ID, mBuilder.build());
can somebody help me to resolve these issue

The .setOngoing(true); should be false, or just remove this line, if you don't put the .setOngoing(boolean) it will be false, so you'll be able to swipe the notification.
More information setOnGoing
Set whether this is an "ongoing" notification. Ongoing notifications cannot be dismissed by the user, so your application or service must take care of canceling them. They are typically used to indicate a background task that the user is actively engaged with (e.g., playing music) or is pending in some way and therefore occupying the device (e.g., a file download, sync operation, active network connection).
So your mBuilder should be like :
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(icon)
.setContentTitle(title)
.setAutoCancel(true)
.setContentText(message)
.setOngoing(false); //or just remove it

The setOngoing makes the notification not dismissible
.setOngoing(true);

Why do I never see notification on tablet

I followed this tutorial/example and it mostly works.
https://developer.android.com/google/gcm/client.html#app
When the web service sends out the notification. It comes down into the send notification method with the correct message. The problem is I never see an actual notification on the tablet (it is running not the latest but a newer version of android, I also tried it on 2 tablets).
Here is what my sendNotification looks like. Any ideas?
I have one activity in the app and that is "MainActivity" here if it matters.
private void sendNotification(String msg) {
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
new Intent(this, MainActivity.class), 0);
Intent resultIntent = new Intent(this, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
//.setSmallIcon(R.drawable.ic_stat_gcm)
.setContentTitle("My Messages")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText("test"))
.setContentText("Test");
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}

According to the Notifications Guide the notification must have at least
A small icon, set by setSmallIcon()
A title, set by setContentTitle()
Detail text, set by setContentText()
So setSmallIcon() is required.
What the documentation doesn't mention is that if something is missing it'll just silently not work without any warnings.

widget doesn't show notification

I want notify a notification on a widget. but it doesn't show it
I call this function but in emulator android 4.3 just play sound when call this function. and it doesn't show any notification
void DisplayZiyaratPage()
{
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this)
.setContentTitle("Title")
.setContentText("text")
.setSound(Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.alarm_sound))
.setDefaults(Notification.DEFAULT_VIBRATE);
Intent intent = new Intent(this, ZiyaratActivity.class);
PendingIntent pendingIntent =PendingIntent.getActivity(this, 0, intent, 0);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}

try this
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!");
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(this, ResultActivity.class);
// The stack builder object will contain an artificial back stack for the
// started Activity.
// This ensures that navigating backward from the Activity leads out of
// your application to the Home screen.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(ResultActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(mId, mBuilder.build());
the NotificationCompat.Builder class has been added to the Support Package so we can use this to support API level v4 and up:
http://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html
If your app supports versions of Android as old as API level 4, you can instead use NotificationCompat.Builder, available in the Android Support library.

Android notification Resume Activity

I'm trying to make a notification when users pause my app. So to make it easier, users can go quickly to the application using notificaction. This is the code i'm using. It works for all versions before android 4 and i don't know which is the problem
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Titulo")
.setContentText("Titulo");
mBuilder.setOngoing(true);
// Creates an explicit intent for an Activity this
Intent resultIntent = new Intent(getApplicationContext(), MainActivity.class);
// put the flags
resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(MainActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(mId, mBuilder.build());
So when i press the notification in android 4.0 and higher, the activity is created again instead of resume. any help please, i can't make it work.
EDIT ( forget about manifest singletop )
android:launchMode="singleTop" same result, not working...
My activity contains a map. I'm using the new version of google maps. v2.

I just tried PendingIntent.FLAG_CANCEL_CURRENT and seems to work for me
public void showNotification(String header,String message){
// define sound URI, the sound to be played when there's a notification
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Intent intent = new Intent(this, MainActivity.class);
//PendingIntent.FLAG_CANCEL_CURRENT will bring the app back up again
PendingIntent pIntent = PendingIntent.getActivity(MainActivity.this,PendingIntent.FLAG_CANCEL_CURRENT, intent, 0);
Notification mNotification = new Notification.Builder(this)
.setContentTitle(header)
.setContentText(message)
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(pIntent)
.setSound(soundUri)
.addAction(R.drawable.ic_launcher, "View", pIntent)
.addAction(0, "Remind", pIntent)
.setOngoing(true)//optional
.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, mNotification);
}

Use android:launchMode="singleTop" in the manifest declaration of MainActivity

The only solution that actually worked for me after doing a lot of search is to do the following :
NotificationCompat.Builder builder = new NotificationCompat.Builder(this).set...(...).set...(..);
Intent resultIntent = new Intent(this, MainClass.class);
resultIntent.setAction("android.intent.action.MAIN");
resultIntent.addCategory("android.intent.category.LAUNCHER");
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, builder.build());
this opens your current activiy without creating another one !

SOLUTION provided by #Patrick taken from the question and added as answer:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.logo)
.setContentTitle(getString(R.string.txt))
.setContentText(getString(R.string.txt));
mBuilder.setOngoing(true);
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(this, Activity.class);
resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
// The stack builder object will contain an artificial back stack for the
// started Activity.
// This ensures that navigating backward from the Activity leads out of
// your application to the Home screen.
TaskStackBuilder stackBuilder = TaskStackBuilder.from(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(Activity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, 0);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(mId, mBuilder.getNotification());

How to add a Dynamic image instead of notification icon in android?

I used below code for displaying notification in notification Bar.
it worked fine.
But i need to display notification icon dynamically that will come from web service.
How i can do?
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification note = new Notification(R.drawable.image,"status message", System.currentTimeMillis());
Intent in = new Intent(Notify.this,CommentU.class);
PendingIntent pi = PendingIntent.getActivity(Notify.this, 0, in, 0);
note.setLatestEventInfo(Notify.this,"NotificationTitle", "You have a new Commentio", pi);
note.number = ++count;
note.vibrate = new long[] { 500l, 200l, 200l, 500l };
note.flags |= Notification.FLAG_AUTO_CANCEL;
nm.notify(NOTIFY_ME_ID, note);
Thanks in Advance.

I have one suggestion for you: you have to download that image which you want to show and then you can set that as bitmap: check below code. I have created one BITMAP.
its look link :
for this you have to add android-support-v4.jar
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
this).setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("My notification").setLargeIcon(BITMAP)
.setContentText("Hello World!");
Intent resultIntent = new Intent(this, test.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(test.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(NOTIFY_ME_ID, mBuilder.build());
for more detail chekc this link.
Removing notifications
Notifications remain visible until one of the following happens:
The user dismisses the notification either individually or by using "Clear All" (if the notification can be cleared).
The user clicks the notification, and you called setAutoCancel() when you created the notification.
You call cancel() for a specific notification ID. This method also deletes ongoing notifications.
You call cancelAll(), which removes all of the notifications you previously issued.
Edited: just replace this.
mBuilder = new NotificationCompat.Builder(
this).setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("My notification").setLargeIcon(BITMAP)
.setAutoCancel(true)
.setContentText("Hello World!");

just add some icons in your resource folder and then
int myIcon = R.drawable.image;
your logic goes here ....
and change value of icon according to your logic like myIcon = R.drawable.somenewimage;
and then finally set your notification
Notification note = new Notification(myIcon,"status message", System.currentTimeMillis());
