i spend a lot of time to resolve my problem. i have written a messenger client in android. my application receive income message and raise a notification. in notification bar i display each income message in a notification item. when click to notification item it will open a conversation activity to list all messages from the beginning until now. everything dose perfect but when i click another item in notification bar, nothing happen! (it must reload data for another conversation). This is my code to raise a notification:
private void showNotification(String message, Class activity, Message messageObject) {
//Get the Notification Service
NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence text = message;//getText(R.string.service_started);
Notification notification = new Notification(R.drawable.ic_launcher, text, System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;
Intent callbackIntent = new Intent(context, activity);
if(messageObject != null)
{
callbackIntent.putExtra("conversation", MessageManager.getProvider().getConversation(messageObject.getConversationId()));
}
//callbackIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
int myUniqueValue = new Random().nextInt();
PendingIntent contentIntent = PendingIntent.getActivity(context, myUniqueValue, callbackIntent, PendingIntent.FLAG_ONE_SHOT);
notification.setLatestEventInfo(context, messageObject.getFrom(), text, contentIntent);
notificationManager.notify(messageObject.getFrom(), myUniqueValue, notification);
}
This is code block to call showNotification function
showNotification(message.getBody(), ConversationActivity.class, messageObject);
Despite your efforts to supply a unique value, those PendingIntents are all treated as the same by the system, so once you click one, the rest are rendered inert.
You'll need to add something distinguishing to callbackIntent; I suggest inventing a data URI that includes the conversation ID or something else that's guaranteed to be different for each notification (see setData).
Finally, I'd encourage you to try to collapse multiple notifications into one icon—you don't want to spam the user. See the Notifications section in the Android Design guide, under "Stack your notifications".
i changed my code and it work very well
private void showNotification(Context context, CharSequence contentTitle, CharSequence contentText, CharSequence notificationContent, Class activity, Conversation conversation) {
//Get the Notification Service
NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher, notificationContent, System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;
Intent callbackIntent = new Intent(context, activity);
if(conversation != null)
{
callbackIntent.putExtra("conversation", conversation);
}
callbackIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
int myUniqueValue = new Random().nextInt();
PendingIntent contentIntent = PendingIntent.getActivity(context, myUniqueValue, callbackIntent, PendingIntent.FLAG_ONE_SHOT);
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
notificationManager.notify(myUniqueValue, notification);
}

I am developing an application in which i implemented Push notification functionality.
My code of onMessage - GCMIntentService.java is:
#Override
protected void onMessage(Context context, Intent data) {
String message = data.getExtras().getString("message");
displayMessage(context, message);
generateNotification(context, message);
}
And code of generateNotification -
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);
Intent notificationIntent = new Intent(context, GCMMessageView.class);
notificationIntent.putExtra("message", message);
// 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, 0,notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
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(0, notification);
}
This code is working fine. I am getting push message and notification.
=>But when i send more then one message the notification gets over write. And i am able to see only last notification in status bar.
The need of application is that - if i send more then one notification then all should be display in status bar.
So please guide me what should i do for that in my code.
Try to put different notification id (i.e. nid) in intent and notify instead of 0 for each new notification this will prevent over writing your notification
PendingIntent intent = PendingIntent.getActivity(context, nid,notificationIntent, 0);
and
notificationManager.notify(nid, notification);
Hope this will help you
Get random numbers:
Random random = new Random();
int m = random.nextInt(9999 - 1000) + 1000;
Instead of:
notificationManager.notify(0, notification);
use:
notificationManager.notify(m, notification);
You need to update your Notification ID when you fire a Notification. in
notificationManager.notify(ID, notification);
How?
To set up a notification so it can be different, issue it with a notification ID by calling NotificationManager.notify(ID, notification). To change this notification once you've issued it, create a NotificationCompat.Builder object, build a Notification object from it, and issue the Notification with the Different ID you are not used previously.
If the previous notification is still visible, the system updates it from the contents of the Notification object. If the previous notification has been dismissed, a new notification is created instead.
For more information go to official docs
hello you need to pass unique notification id in notify method.
Below is the code for pass unique notification id:
//"CommonUtilities.getValudeFromOreference" is the method created by me to get value from savedPreferences.
String notificationId = CommonUtilities.getValueFromPreference(context, Global.NOTIFICATION_ID, "0");
int notificationIdinInt = Integer.parseInt(notificationId);
notificationManager.notify(notificationIdinInt, notification);
// will increment notification id for uniqueness
notificationIdinInt = notificationIdinInt + 1;
CommonUtilities.saveValueToPreference(context, Global.NOTIFICATION_ID, notificationIdinInt + "");
//Above "CommonUtilities.saveValueToPreference" is the method created by me to save new value in savePreferences.
Let me know if you need more detail information or any query. :)
notificationManager.notify(Different_id_everytime, notification);
I send a few notification on the notification bar, i wanted to clear all of it when one of the notification is clicked. For now I clear one by one by using Flag. I know notificationManager.cancelAll() could clear all the notification but where should i put so that i can trigger once one of the notification is clicked.
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);
Intent notificationIntent = new Intent(context, MainActivity.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, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(msgid, notification);
//notificationManager.cancelAll(); //i wan to clear all when the notification is clicked, where should i put this line?
}
My solution is to call it at onResume().
#Override
protected void onResume() {
super.onResume();
// Clear all notification
NotificationManager nMgr = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
nMgr.cancelAll();
}
You should use a pending intent that sends a broadcast and then put in place a broadcast receiver that will cancel all your notifications. It is best to memorize all notifications IDs and delete them one by one.
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:
I have a method for creating notification. I want to clear notification number as soon as a user clicks on status notification.
public void createNotification(){
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notification=null;
notification = new Notification(R.drawable.ic_launcher, "You have a new message", System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.number = **count**++;
Intent intent = new Intent();
intent.setClass(TabInterfaceActivity.this, TabInterfaceActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent activity = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.contentIntent = activity;
notification.setLatestEventInfo(this, " New Message", message, notification.contentIntent);
}
If by "I want to clear notification number" you mean you want to keep the notification itself still displayed, but you want just to update/remove counter, then you should set your notification PendingIntent to point to your code that would handle this scenario for you, and when it completes it shall redirect to your target TabInterfaceActivity (or you can make it more flexible and pass target in PendingIntent's Bundle).
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.
