Show Notifications in Android Without Using Intent

I am a beginner in android .I want to show notification in my app . I use the following code
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager notificationManager = (NotificationManager) getSystemService(ns);
int icon = R.drawable.icon;
CharSequence tickerText = "";
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, tickerText, when);
Context context = getApplicationContext();
CharSequence contentTitle = "Hello";
CharSequence contentText = "Welcome ";
Intent notificationIntent = new Intent();
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, null, 0);
notification.defaults |= Notification.DEFAULT_SOUND;
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
notificationManager.notify(HELLO_ID, notification);
But my problem is whenever run my app the intent is loaded with icon .Then the icon is show in the status bar . how to show notifications without using intent ? please help

I'm not sure if this is what you want, but if you want to show some quick notification, toasts come to mind:
Context context = getApplicationContext();
CharSequence text = "Notification!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
You can change how long the toast is shown with duration.

Notification sound not playing

I know this question has been asked many times, but I'm still having issues getting it working.
In my application, I create a notification to prompt the user of some event and I'd like to play a sound that has been packaged as a raw resource within the application.
I create my notification instance:
Notification notification = new Notification(
R.drawable.some_image,
"some meaningful name",
System.currentTimeMillis() );
notification.setLatestEventInfo(...)
Then set some attributes on that notification:
notification.sound = Uri.parse( "android.resource://com.my.package/" + R.raw.some_mp3_file );
notification.flags = Notification.FLAG_INSISTENT;
Finally I invoke the NotificationManager to display the notification:
notificationManager.notify( 1, notification );
The notification does shows up, but the sound doesn't play.
Am I doing something wrong? Is there a <uses-permission> I'm missing? I can't see anything that I've done differently from anyone else that seems to have gotten it working.
For what it's worth, I'm testing directly on a Nexus 7.

try to look at below code. may help you out to solve your problems.
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager notificationManager = (NotificationManager) getSystemService(ns);
int icon = R.drawable.update;
CharSequence tickerText = "assignments";
long when = System.currentTimeMillis();
Notification assignmentNotification = new Notification(icon, tickerText, when);
**For sound** assignmentNotification.defaults |= Notification.DEFAULT_SOUND;
long[] vibrate = {0,100,200,300};
**For vibrate** assignmentNotification.vibrate = vibrate;
Context context = getApplicationContext();
CharSequence contentTitle = "check assignments";
CharSequence contentText = "chek ur app for assignments ";
Intent notificationIntent = new Intent(context, ViewAssignmentnotificationActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent,0);
assignmentNotification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
** final int id = 2;

Please see this answer; It tells you that you have to explicitly specify notification.sound to play that tone;

Custom notification sound not playing

I'm trying to make a custom sound play on a status bar notification. The .mp3 file is in res/raw/. But when I notify the user the sound is not played. I've tryied with MediaPlayer, and it works, but I dont want to make it play with MediaPlayer.
Here is my method:
public void showNotification()
{
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
int icon = R.drawable.feedback; // icon from resources
CharSequence tickerText = mContext.getString(R.string.statusbar_notification); // ticker-text
long when = System.currentTimeMillis(); // notification time
Context context = getApplicationContext(); // application Context
CharSequence contentTitle = mContext.getString(R.string.statusbar_notification); // message title
CharSequence contentText = mContext.getString(R.string.statusbar_notificatione_detailed); // message text
Intent notificationIntent = new Intent(mContext, Main.class);
PendingIntent contentIntent = PendingIntent.getActivity(mContext, 0, notificationIntent, 0);
// the next two lines initialize the Notification, using the configurations above
Notification notification = new Notification(icon, tickerText, when);
//notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_VIBRATE;
notification.sound = Uri.parse("android.resource://" + getPackageName() + "/R.raw.notificationsound");
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
mNotificationManager.notify(1, notification);
}
Thanks.

From the documentation for ContentResolver:
The Uri should be one of the following formats:
android.resource://package_name/id_number
You are passing the String "R.raw.notificationsound" which means nothing.
Instead try this:
notification.sound = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notificationsound );

Does anyone know how to impose counters on status bar notifications in Honeycomb

I am trying to use number field of Notification class to get "number of events" associated with each notification. For Ex. If I have two unread emails, email icon in the status bar should show "2" imposed on the email icon. I think this was working fine with froyo but somehow I am not able to make it work for Honeycomb. This is how my code looks like
PendingIntent contentIntent;
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification_layout);
Notification.Builder builder = new Notification.Builder(this);
builder.getNotification().number = 2;
builder.setSmallIcon(R.drawable.phone_missedcall);
builder.setTicker("ABCD & Status : Missed Call");
notificationIntent = new Intent (this, NotificationSBActivity.class);
contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
builder.setContentIntent(contentIntent);
contentView = new RemoteViews(getPackageName(), R.layout.custom_notification_layout);
contentView.setImageViewResource(R.id.contact_image, R.drawable.ic_contact_picture);
contentView.setTextViewText(R.id.line_name, "Line 2: Cisco");
builder.setContent(contentView);
But it doesn't show "2" imposed over the icon. Is there any other way to get the counter in Honeycomb ??
Also, tried
int icon = R.drawable.phone_app; // icon from resources
CharSequence tickerText = "Hello"; // ticker-text
long when = System.currentTimeMillis(); // notification time
Context context = getApplicationContext(); // application Context
CharSequence contentTitle = "My notification"; // message title
CharSequence contentText = "Hello World!"; // message text
notificationIntent = new Intent(this, NotificationSBActivity.class);
contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
// the next two lines initialize the Notification, using the configurations above
Notification notification = new Notification(icon, tickerText, when);
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
notification.number = 2;
mNotificationManager.notify(0, notification);
Please let me know if anyone has tried notification counters on Honeycomb ??

Notification is set immediately in Android

Call to method:
initNotificatie(endDate.getTime());
Log.d("temp", "end: " + endDate.toGMTString()); // end: 13 Apr 2011 12:45:00 GMT
The method:
public void initNotificatie(long when) {
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
int icon = R.drawable.herinnering_button_dropdown;
String contentTitleString = getString(R.string.notification_title);
String contentTekstString = getString(R.string.notification_tekst);
CharSequence tickerText = "NotificationTekst";
Notification notification = new Notification(icon, tickerText, when);
Context context = getApplicationContext();
CharSequence contentTitle = contentTitleString;
CharSequence contentText = contentTekstString;
Intent notificationIntent = new Intent(this, MapDashboardActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_VIBRATE;
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
final int HELLO_ID = 1;
mNotificationManager.notify(HELLO_ID, notification);
}
How come this notification is set immediately while the notification is set for tomorrow? Is this because the notification constructor I'm using is deprecated? I can only use that one because I'm programming on level 4.

The when parameter refers to the time to be shown in the time field. It is not the time at which notification should be shown. In order to do that, use AlarmManager.
