How can I set delete intent to my code?

I've searched many times but I was not able to find what I actually needed,
There is something on stackoverflow like this and this
but I need to implement my code for api level 8 not 11. So how can I implement it in my code?
My code is here:
....
mNotification = new Notification(icon, tickerText, when);
//create the content which is shown in the notification pulldown
mContentTitle = mContext.getString(R.string.noti_comes_t_l); //Full title of the notification in the pull down
CharSequence contentText = "click to see notification"; //Text of the notification in the pull down
//you have to set a PendingIntent on a notification to tell the system what you want it to do when the notification is selected
//I don't want to use this here so I'm just creating a blank one
mContentIntent = PendingIntent.getActivity(mContext, 0, new Intent(mContext, notify.class), 0);
//add the additional content and intent to the notification
mNotification.setLatestEventInfo(mContext, mContentTitle, contentText, mContentIntent);
//make this notification appear in the 'Ongoing events' section
mNotification.flags = Notification.DEFAULT_LIGHTS | Notification.FLAG_AUTO_CANCEL ;
//show the notification
mNotificationManager.notify(NOTIFICATION_ID, mNotification);
....
How can I implement this?

I think you need NotificationCompat from the Support library, you can use this code to generate a notification, adapt it as you need
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(icon)
.setContentTitle(context.getString(R.string.app_name))
.setContentText(message)
.setDeleteIntent(PendingIntent);
mBuilder.setWhen(when);
Intent notificationIntent = new Intent(context, YOURCLASS.class);
notificationIntent.putExtra("url", url);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, random, notificationIntent, PendingIntent.FLAG_ONE_SHOT);
mBuilder.setContentIntent(intent);
Notification notification = mBuilder.build();
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(random, notification);

Android Phonegap GCM Multiple Notification

I am using Phonegap with GCM plugin to show GCM notification.
I am able to display notification correctly but I am not able to show multiple notification. I tried Notification passes old Intent Extras but No results yet.
Please help.
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
int iUniqueId = (int) (System.currentTimeMillis() & 0xfffffff);
// saveCallIntent.setData((Uri.parse("custom://"+System.currentTimeMillis())));
Intent notificationIntent = new Intent(context, JainDharma.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, iUniqueId, notificationIntent, 0);
//PendingIntent contentIntent = PendingIntent.getActivity(context, UNIQUE_INT_PER_CALL, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
//notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3");
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(0, notification);

If you mean that the last notification overrides the previous one, and you wish to change it, you need to change the following :
notificationManager.notify(0, notification);
Use a different id (instead of 0) for each notification and you'll see all of them.
However, you might want to reconsider whether it's such a good idea to show multiple notifications for the same app. I would find that annoying as a user of your app.

Single line notification that is shown across the status bar?

just a simple question: How to make the single-line notification that will disappear after a short time.
Just like Whatsapp's:
My current notification code is still very basic:
Intent intent = new Intent("com.example.MyChat");
PendingIntent pIntent = PendingIntent.getActivity(context, 0, intent, 0);
Notification notification = new Notification.Builder(context)
.setContentTitle("New message from " + name)
.setContentText(message)
.setSmallIcon(R.drawable.ic_launcher).setContentIntent(pIntent)
.getNotification();
notification.defaults |= Notification.DEFAULT_SOUND;
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);
Thanks

This is called the "ticker" and it is shown briefly by the status bar if you set the tickerText property of your Notification.
See setTickerText.

You can use AlarmManager to invoke after a short time, say 5 seconds.
Also you can use a service, which gets launched, when first time the notification appears and it could cancel the notification after some time.
here you can cancel Notification using,
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(NOTFICATION_ID);
Have a look at this post, it might help you as well.

Notification throwing intents without it's extras

I am trying to launch an intent from a notification, but for a reason I don't know the extra is not always sent with the intent.
This is where I create the intent :
NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,
mContext.getString(R.string.text), 0);
Intent intents = new Intent(mContext, DataAppTabs.class);
intents.putExtra(DataAppTabs.REQUEST, DataAppTabs.REQUEST_DMTAB);
intents.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent launchIntent = PendingIntent.getActivity(mContext.getApplicationContext(), DataAppTabs.REQUEST_DMTAB, intents, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(mContext, "Info", mContext.getString(R.string.enginedmnotification_rebootneeded), launchIntent);
notification.flags = Notification.FLAG_NO_CLEAR;
notification.flags |= Notification.FLAG_ONLY_ALERT_ONCE;
notification.defaults = Notification.DEFAULT_ALL;
notificationManager.notify(DataAppTabs.REQUEST_DMTAB, notification);
In the DataAppTabs class I overrided onCreate() and onNewIntent(). When the notification appears, if I click on it it opens the correct Activity (DataAppTabs, which is a TabActivity), it triggers onCreate or onNewIntent if the activity was already started, but the extra "REQUEST" is not always set (getExtras() is sometimes null).
I have found the same question here with answers telling me I had to use the "FLAG_ACTIVITY_SINGLE_TOP" flag, but it still doesn't work all the time and I am not able to reproduce the problem every time.
Is it something I did wrong ?
Thanks

// Displaying Notification
NotificationManager manager = (NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon, "MyNotification", System.currentTimeMillis());
PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, new Intent(getApplicationContext(), Sample.class), 0);
notification.setLatestEventInfo(getApplicationContext(), "Notification Title", "Notification Data", contentIntent);
notification.flags = Notification.FLAG_INSISTENT;
int NOTIFICATION_ID=(int)System.currentTimeMillis();
manager.notify(NOTIFICATION_ID, notification);
// Sample.class is the activity to which you want to go when you click on Notification

Android Notification intent to clear it self

I have read many examples of how to create notification messages.
What i wanted to achieve, is because the notification will be executed by a widget, i would like
the notification intent when clicked to clear it self when the user clicks on it.I do not have an activity to return to.
The notification for my purposes will just plainly notify, nothing else.
So what would be the code of an intent that just clear/cancel itself.
The code below is an activity launched by a button(button code not included) the notification will be fired up by a background service.
CharSequence title = "Hello";
CharSequence message = "Hello, Android!";
final NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
final Notification notification = new Notification(R.drawable.icon,"A New Message!",System.currentTimeMillis());
notification.defaults=Notification.FLAG_ONLY_ALERT_ONCE+Notification.FLAG_AUTO_CANCEL;
Intent notificationIntent = new Intent(this, AndroidNotifications.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,notificationIntent, 0);
notification.setLatestEventInfo(AndroidNotifications.this, title,message, pendingIntent);
notificationManager.notify(NOTIFICATION_ID, notification);
Thanks

Check out FLAG_AUTO_CANCEL
Bit to be bitwise-ored into the flags field that should be set if the notification should be canceled when it is clicked by the user.
EDIT :
notification.flags |= Notification.FLAG_AUTO_CANCEL;

Set the flags in notification.flags instead of notification.defaults.
Example:
notification.flags |= Notification.FLAG_ONLY_ALERT_ONCE | Notification.FLAG_AUTO_CANCEL;

If you're using NotificationCompat.Builder (a part of android.support.v4) then simply call its object's method setAutoCancel
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setAutoCancel(true);
Some guys were reporting that setAutoCancel() did not work for them, so you may try this way as well
builder.build().flags |= Notification.FLAG_AUTO_CANCEL;

The only way I can see of doing this is to have your Notification's Intent point to a background Service. When this Service is launched, it would clear the given Notification using NotificationManager.cancel(int id). The Service would then stop itself. It's not pretty, and would not be easy to implement, but I can't find any other way of doing it.

/**
Post a notification to be shown in the status bar.
Obs.: You must save this values somewhere or even pass it as an extra through Intent to use it later
*/
notificationManager.notify(NOTIFICATION_ID, notification);
/**
Cancel a previously shown notification given the notification id you've saved before
*/
notificationmanager.cancel(NOTIFICATION_ID);

Using setContentIntent should solve your problem:
.setContentIntent(PendingIntent.getActivity(this, 0, new Intent(), 0));
For example:
NotificationCompat.Builder mBuilder= new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("title")
.setAutoCancel(true)
.setContentText("content")
.setContentIntent(PendingIntent.getActivity(this, 0, new Intent(), 0));
NotificationManager notificationManager= (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, mBuilder.build());
Often you might want to direct the user to the relevant content and so might replace 'new Intent()' with something else.
