android notification issue

I am working on an Android application.The app is like native sms application.I am facing a problem in notification part. In native app, they handle the notification in the following way.
1)if messages from an specific number ,then the click on the notification will lead to the chat page of the corresponding contact and the notification will clear.
2)if messages from the different number, then the click on the notification will lead to home page and notification won't clear.
I had done the first part and I don't have any idea to do the second part.
Is there any way to leave the notification part without clear and call an intent.?

you have to add a flag:
notification.flags |= Notification.FLAG_ONGOING_EVENT;
here a whole example:
private static final int NOTIFICATION_EX = 0;
private NotificationManager notificationManager;
...
in onCreate:
notificationManager = (NotificationManager)
getSystemService(Context.NOTIFICATION_SERVICE);
int icon = R.drawable.youricon;
CharSequence tickerText = "Sticky notification";
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, tickerText, when);
Context context = getApplicationContext();
CharSequence contentTitle = "Sticky notification";
CharSequence contentText = "...click here and it wont go away...";
Intent notificationIntent = new Intent(this, mainmenu.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(this,
0, notificationIntent, 0);
notification.setLatestEventInfo(context, contentTitle,
contentText, contentIntent);
notification.flags |= Notification.FLAG_ONGOING_EVENT;
notificationManager.notify(NOTIFICATION_EX, notification);
the intent you can adjust to whatever you like.

You will have to create two different kind of notification, the first one you have already implemented, and the second one you can just copy the first one and check if the number is a different one use the second notification and set the flags to not clear notification2.flags |= Notification.FLAG_ONGOING_EVENT; on click with the HomeActivity in the PendingIntent which has Intent:

How can I cancel a notification when the user clicks on it?

I would like to create a notification that clears automatically when the user presses it and has no other behaviuour. The notification below works fine but when i press on it it takes me to the activity "MyActivity" (even having to define an intent seems a bit unecessary when I don't want to use it...)
Using FLAG_AUTO_CANCEL doesn't seem to have any effect at all.
Update: Sorry, I have found the FLAG_AUTO CANCEL does work, that is the notification is cleared from the status bar. I guess I am really tring to write an intent that does nothing (or completely delete the intent).
Code...
Notification notification = new Notification(R.drawable.success, res.getString(R.string.messages_sent), System.currentTimeMillis());
//Define the expanded message and intent
Context context = getApplicationContext();
CharSequence contentTitle = res.getString("My content title");
Intent notificationIntent = new Intent(this, MyActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0 );
notification.setLatestEventInfo(context, contentTitle, mStrSuccessMessage, contentIntent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
//Pass the notification to the notification manager
mNotificationManager.notify(1, notification);

Use an empty intent without an actual action.
PendingIntent pi = PendingIntent.getActivity(this, 0, new Intent(), 0);

I don't think you can. You can have MyActivity exit immediately though: call finish() from onCreate().

Android Status Bar Notification: make it un-clearable and have it return to app (not start a new instance)

I am developing an Android app and I want a status bar notification that cannot be cleared by the user. Does anyone know how to do that? I've seen them with apps like Skimble where a non-clearable notification appears while using the application.
Also, I'd when the user clicks/presses the notification, I want it to return to the app instance that is already running. Right now it starts a new instance. Again like the Skimble app, I just want to return to the already running instance of the app.
Thanks.

I found a solution to this problem. I used FLAG_ONGOING_EVENT to make the notification persist. Here's the code:
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
int icon = R.drawable.mypic;
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, tickerText, when);
notification.flags = Notification.FLAG_ONGOING_EVENT;
Context context = getApplicationContext();
CharSequence contentTitle = "Title Text";
CharSequence contentText = "Content text.";
Intent intent = new Intent(this, MyClass.class);
intent.setAction("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
final int HELLO_ID = 1;
mNotificationManager.notify(HELLO_ID, notification);

Here is the solution for the NotificationCompat.Builder
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("MyApp")
.setContentText("MyMsg")
.setOngoing(true);
More at the Google docs.

notification.setLatestEventInfo is deprecated so you have to use the Notification.builder and if your using 2.X and lower API you have to use NotificationComacpt.Builder and this is not applicable and I couldn't make my notification stays. so I used setDeleteIntent and pointed to the same activity and on resume method just call the block of code which shows your notification. So it is kinda work around.

Android - notification manager, having a notification without an intent

I would like to be able to fire a notification to alert the users about a timer that has finished, however i do not wish to have an intent when you click the notification.
I've tried passing in null for the intent
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(ns);
int icon = R.drawable.icon;
CharSequence tickerText = "Hello";
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, tickerText, when);
CharSequence contentTitle = "My notification";
CharSequence contentText = "Hello World!";
notification.setLatestEventInfo(context, contentTitle, contentText, null);
mNotificationManager.notify(HELLO_ID, notification);

You may pass the parameter
PendingIntent.getActivity(getApplicationContext(), 0, new Intent(), 0)
instead of
null
on
notification.setLatestEventInfo(context, contentTitle, contentText, null);

The last parameter in setLatestEventInfo() is a PendingIntent and not an Intent. If you need the notification to not do anything when tapped is to pass an empty PendingIntent which is done as follows: PendingIntent.getActivity(context, 0, null, 0).

Interesting question and I would like to see if this works. I did a little digging and found a lot of ppl asking the same question. cbursk seems to have found a hack to get this intended functionality, which is to pass a Dialog to the notification intent instead of an Activity. I'm guessing the Dialog does nothing, or is programmed to dismiss itself right away, not sure. But I'm currently looking at this thread and going to test it out.

Cannot open first notification but opens for the rest

I have some kind of SMS application. So everytime the phone received a new message, it should have a notification and upon clicking it, will launch the activity. Right now, when receiving 1 message, it notifies, removes in the status bar and doesn't not launch the activity. But when receiving 2 or more messages, the first notification cannot launched upon clicking while the rest(2nd, 3rd notification...) can. Below are my codes.
Intent newIntent = new Intent(context, PreviewActivity.class);
newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK+0);
newIntent.setAction(strFxPrimaryKey);
Bundle newBundle = intent.getExtras();
newBundle.putInt(GlobalConstants.PRIMARY_ID, Integer.parseInt(strFxPrimaryKey));
newIntent.putExtras(newBundle);
int icon = R.drawable.notification_fx;
CharSequence tickerText = context.getString(R.string.fx_received);
long when = System.currentTimeMillis();
Notification newNotification = new Notification(icon, tickerText, when);
newNotification.flags |= Notification.FLAG_AUTO_CANCEL; //| Notification.FLAG_ONGOING_EVENT;
PendingIntent contentIntent = PendingIntent.getActivity(context, Integer.parseInt(strFxPrimaryKey), newIntent, 0);
newNotification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
String newNotificationService = Context.NOTIFICATION_SERVICE;
NotificationManager newNotificationManager = (NotificationManager) context.getSystemService(newNotificationService);
newNotificationManager.notify(Integer.parseInt(strFxPrimaryKey), newNotification);
context.startActivity(newIntent);
context.removeStickyBroadcast(intent);
Based on the answers here in the stackoverflow, to create a unique intent, it should have unique action that's why I set the primary key as the action. I also set the request code to primary key to have a unique pending intent. Is there something missing out in my code? Thanks.
EDITED
By the way, whenever I remove the context.startActivity(newIntent);, it works right. Can anyone tell me why? Thanks.
