I want to put a notification in android top bar, and when user click on it, downloadmanager will start download the file. How to set the pendingIntent for this notification?

Android Notifications - Tutorial will definitely help you achieve what you want.
An excerpt of what you want from that is below. You can call the following function:
public void createNotification(View view) {
// Prepare intent which is triggered if the
// notification is selected
Intent intent = new Intent(this, NotificationReceiverActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
// Build notification
// Actions are just fake
Notification noti = new Notification.Builder(this)
.setContentTitle("Title")
.setContentText("Subject").setSmallIcon(R.drawable.icon)
.setContentIntent(pIntent)
.addAction(R.drawable.icon, "Call", pIntent)
.addAction(R.drawable.icon, "And more", pIntent).build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Hide the notification after its selected
noti.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, noti);
}
For starting the download manager, you might have to adjust the function accordingly. Check the tutorial link for detailed understanding. Also there are other relevant answers which might help:

You can define actions you want to happen when interacting with your Notification by adding a PendingIntent.
In the following example a PendingIntent is created to launch the (current) activity.
That intent is then added to the notification in the content section. Once this notification is shown, when you click the content section, the intent is fired and the app gets started or brought back to top.
private static final int NOTIFICATION_ID = 1;
...
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder nb = new NotificationCompat.Builder(this);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
new Intent(this, MainActivity.class)
.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP),
0);
nb.setSmallIcon(R.drawable.abc_ic_ab_back_mtrl_am_alpha)
.setCategory(NotificationCompat.CATEGORY_STATUS)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setContentTitle(getText(R.string.app_name))
.setContentText("Click to launch!")
.setWhen(System.currentTimeMillis())
.setContentIntent(pendingIntent) // Here the "onClick" Intent is added
.setOngoing(false);
nm.notify(NOTIFICATION_ID, nb.build());
In this case the notification is dismissable. If you set .setOngoing(true) you need to remove it by calling .cancel(NOTIFICATION_ID) on an instance of the NotificationManager.

Button/Action not appearing on Wear notification

I'm trying to build an Android application that sends a notification to an Android Wear device.
The notification needs to have a content action set, so that the user can directly activate the action by clicking on the button displayed in the notification.
However, using the below code, the action appears on the next page, just like a regular action, and not on the notification:
Context context = getApplicationContext();
// Create an intent for the reply action
Intent actionIntent = new Intent(this, getClass());
PendingIntent actionPendingIntent =
PendingIntent.getActivity(this, 0, actionIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
// Create the action
NotificationCompat.Action action =
new NotificationCompat.Action.Builder(R.drawable.common_signin_btn_icon_dark, "ActionTitle", actionPendingIntent).build();
NotificationCompat.Builder builder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.common_signin_btn_icon_dark)
.setContentTitle("Title")
.setContentText("Context Text")
.addAction(action)
.extend(new NotificationCompat.WearableExtender()
.setContentAction(0));
// Get an instance of the NotificationManager service
NotificationManagerCompat notificationManager =
NotificationManagerCompat.from(this);
// Build the notification and issues it with notification manager.
notificationManager.notify(0, builder.build());
This is how it looks:
After swiping:
It is supposed to all be on a single page, with the Action button imbedded into the notification, like this:
What am I doing wrong?

Delete notification notification.builder on content click

I have a notification that have 2 actions. One intent open an Activity, the other open browser web.
my code:
Intent intent1 = new Intent(context, NotificationClickActivity.class);
PendingIntent pIntent1 = PendingIntent.getActivity(context, 0, intent1, PendingIntent.FLAG_CANCEL_CURRENT);
String url = "http://www.google.com";
Intent browserIntent = new Intent(Intent.ACTION_VIEW);
browserIntent.setData(Uri.parse(url));
PendingIntent pBrowserIntent = PendingIntent.getActivity(context, 1, browserIntent, PendingIntent.FLAG_CANCEL_CURRENT);
// Build notification
Notification noti = new Notification.Builder(context)
.setContentTitle(title)
.setContentText(shortDescription)
.setStyle(new Notification.BigTextStyle().bigText(longDescription))
.setSmallIcon(R.drawable.small_defaulticon)
.setAutoCancel(true)
.setContentIntent(pIntent1)
.addAction(R.drawable.playstore_icon_32, "Dettagli", pIntent1)
.setContentIntent(pBrowserIntent)
.addAction(R.drawable.small_defaulticon, "Vai al sito", pBrowserIntent).build();
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
// Hide the notification after its selected
noti.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, noti);
If i click on the notification it goes away, but if I click on one of the 2 Actions it open the right intent but notification doesn't cleared.
I try also .setDeleteIntent(myPendingIntent) but nothing... I wonder where I am going wrong...
A screen of my notification...
Thank you!
A notification is never dismissed when an action button is pressed. It just sends you associated intent. If you want it to dismiss, you need to call NoficationManager.cancel(int id) to cancel it yourself. You will normally do it in the same method, which handles action button intent.
Notification.FLAG_AUTO_CANCEL flag you tried to use is only applied to notification body and not to action buttons.
use cancel() in the activity that started by your action to dismiss the notification
try this
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setDefaults(Notification.DEFAULT_ALL);
and try to send uniqueId in notificationManager.notify(uniqueId, noti);

Click on status bar notification and show details?

I wrote an app that saves local notification at specific time in future and when that time is reached it shows notification in status bar even if the app is not running. My question is: it is possible to show some additional information to user when he clicks on notification in status bar?
Yes it is possible to display additional information when user taps on that particular notification. While writing code to display notification, you will find one setLatestEventInfo method. Use it. Its exactly what you need.
public void createNotification(View view) {
NotificationManager notificationManager = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,
"A new notification", System.currentTimeMillis());
// Hide the notification after its selected
notification.flags |= Notification.FLAG_AUTO_CANCEL;
Intent intent = new Intent(this, NotificationReceiver.class);
PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
notification.setLatestEventInfo(this, "This is the title",
"This is the text", activity);
notification.number += 1;
notificationManager.notify(0, 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.
