I am using an Activitiy with various Tabs on it. From a different part of the application, Notifications are created to tell the user that something has changed. I now managed to Call the Activity, when the user clicks on the Notification. But how can i determine wheter a Activity is created the "normal" way during runtime or by clicking on the notification?
(Depending on the notification clicked, i want to forward to another tab instead of showing the main Tab.)
Intent intent = new Intent(ctx, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(ctx, 0, intent, 0);
// TODO: Replace with .Build() for api >= 16
Notification noti = new Notification.Builder(ctx)
.setContentTitle("Notification"
.setContentText(this.getName())
.setSmallIcon(R.drawable.icon)
.setContentIntent(pendingIntent)
.setDefaults(
Notification.DEFAULT_SOUND
| Notification.DEFAULT_LIGHTS)
.setAutoCancel(true)
.getNotification();
NotificationManager notificationManager = (NotificationManager) ctx
.getSystemService(Context.NOTIFICATION_SERVICE);
// Hide the notification after its selected
notificationManager.notify(this.getId(), noti);
This successfully calls my MainActivity. But is there some Method that is called when the Activity is triggered by the pendingIntent?
Thought about to define something like this in the Main Activity:
onTriggeredByNotification(Notification noti){
//determinte tab, depending on Notification.
}
Pass a boolean value from notification and check for the same in the onCreate method of the activity.
Intent intent = new Intent(ctx, MainActivity.class);
intent.putExtra("fromNotification", true);
...
if (getIntent().getExtras() != null) {
Bundle b = getIntent().getExtras();
boolean cameFromNotification = b.getBoolean("fromNotification");
}
You can try this in your Notification
Intent intent=new Intent();
intent.setAction("Activity1");
In the Activity override onNewIntent() method and get action so you can determine the activity is called or not.
Better than using the reserved action field of your intent as specified by #ricintech, you could use an extra parameter in your pending intent and detect it in your onCreate method and in your onNewIntent metod inside your activity.

I am seriously confused now, I have been reading several SE examples and they all seem to be doing slightly different things.
What i want to do: Is have a single Activity called NotificationActivity, when I click on a notification it must open that activity and provide the activity with a DeviceId. I don't want to override or update any pending activities. Each activity should be its own intent.
There should only be once instance of NotificationActivity.
here is the code I have so far:
MyGcmListenerService:
Intent intent = new Intent(this, NotificationActivity.class);
intent.setAction(Intent.ACTION_VIEW);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
//ADD My Extras
intent.putExtra(CommonBundleAttributes.CONNECTING_ACTIVITY_DEVICE_ID, content.DeviceId);
intent.putExtra(CommonBundleAttributes.CONNECTING_ACTIVITY_DEVICE_TYPE_ID, content.DeviceTypeId);
intent.putExtra(CommonBundleAttributes.CONNECTING_ACTIVITY_DEVICE_NAME, content.DeviceName);
//
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(content.DeviceName)
.setContentText("Notification")
.setAutoCancel(true)
.setSound(ingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setGroup("Mi:" + content.DeviceId)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(NotificationID++, notificationBuilder.build());
and my NotificationActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notification);
deviceId = getIntent().getExtras().getLong(CommonBundleAttributes.CONNECTING_ACTIVITY_DEVICE_ID, -1);
deviceName = getIntent().getExtras().getString(CommonBundleAttributes.CONNECTING_ACTIVITY_DEVICE_NAME, "");
deviceTypeId = getIntent().getExtras().getInt(CommonBundleAttributes.CONNECTING_ACTIVITY_DEVICE_TYPE_ID, 0);
What am I missing here/ I think I am getting mixed up with all the different flags and launcher types.
If there is already an NotificationActivty in memory, I want to close it and open a new one with the latest intent. If there are 3 notifications on the users phones, and they click on all three. it must open the NotificationActivty for the last clicked Notification.
There must be an issue with my pending intent?
In NotificationActivity, you collect int or long value using following code i.e.
notificationID = getIntent().getExtras().getInt(CommonBundleAttributes.CONNECTING_ACTIVITY_NOTIFICATIONID, 0);
then please pass a proper value with putExtra() i.e. if collect int then pass Integer.parseInt(content.DeviceId) or collect long then pass Long.parseLong(content.DeviceId)
hope it's helpful to you
In Notification class add this line
intent.putExtra(CommonBundleAttributes.CONNECTING_ACTIVITY_NOTIFICATIONID, NotificationID);
In NotificationActivity
notificationID = getIntent().getExtras().getInt(CommonBundleAttributes.CONNECTING_ACTIVITY_NOTIFICATIONID, 0);
I have created a custom notification, but when i pause the activity with the home button and a notification arrives, i press the notification and it creates a new activity and doesnt resume the previews activity and when i press the back button it goes to the previews one which is the same window. I have tried singleTop, singleTask, singleIntent, it works but it doesnt update the activity when a message enters, it is like the previews activity was in pause. how can i fix it?
if there is no solution i though in resuming the activity or destroy the paused activity or maybe restart the activity, is there a way to do this?
public void CustomNotification(String strtext) {
// Using RemoteViews to bind custom layouts into Notification
RemoteViews remoteViews = new RemoteViews(getPackageName(),
R.layout.customnotification);
// Set Notification Title
String strtitle = getString(R.string.customnotificationtitle);
// Open NotificationView Class on Notification Click
Intent intent = new Intent(this, NotificationView.class);
// Send data to NotificationView Class
intent.putExtra("title", strtitle);
intent.putExtra("text", strtext);
intent.putExtra("String T", "");
//intent.putExtra("Integer C", 0);
// Open NotificationView.java Activity

EDITED
ANSWER:
the answer was to add:
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_NEW_TASK);
because when i was in the same window and i pressed the home button, the activity was in paused, then if some notification arrived it brought me to that window but didnt updated the messages so I needed to create a new intent and erase the previous one which was in pause. so that code did the Job.
To update your activity, you should override onNewIntent():
protected void onNewIntent (Intent intent) {
super.onNewIntent(intent);
//reload your data here
}
Android Docs say:
void onNewIntent (Intent intent)
This is called for activities that set launchMode to "singleTop" in
their package, or if a client used the FLAG_ACTIVITY_SINGLE_TOP flag
when calling startActivity(Intent). In either case, when the activity
is re-launched while at the top of the activity stack instead of a new
instance of the activity being started, onNewIntent() will be called
on the existing instance with the Intent that was used to re-launch
it.
An activity will always be paused before receiving a new intent, so
you can count on onResume() being called after this method.
Note that getIntent() still returns the original Intent. You can use
setIntent(Intent) to update it to this new Intent.
Note: as the docs say, you need to set android:launchMode="singleTop" in your Activity tag (in AndroidManifest).
try this in your service code to use notification :
private static final int NOTIFY_ME_ID = 1222;
NotificationManager mNotificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
private void Notifi(String message){
int requestID = (int) System.currentTimeMillis();
Intent intent = new Intent(Intent.ACTION_MAIN);
//CLEAR PREVIOUS ACTIVITIES AND CREATE A NEW ONE
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setComponent(new ComponentName("packagenameofyourapplication",
"packagenameofyourapplication.NotificationView"));
PendingIntent pintent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
Notification notif = new Notification.Builder(this)
.setContentTitle(getString(R.string.notification_titel)).setContentText(message)
.setSmallIcon(R.drawable.ic_launcher).setAutoCancel(true)
.setContentIntent(pintent).build();
notif.flags = Notification.FLAG_NO_CLEAR;
mNotificationManager.notify(NOTIFY_ME_ID, notif);
}
Is it possible not launch new activity if we receive a push notification while the app is running?
My activity works with fragments and I want to do transition to a determinate fragment when the notification is received. My activity have data that I need to show the fragments. The problem is that when I receive the push notification while the app is running the method onDestroy is called and here I clear the data and then the app crash because the data are null. How can I do to not create new activity when the app receive a push notification while is running? In case the app is running I want that if you click the notification do a transition fragment, not create again the activity.
Thanks in advance.
First of all, I think that you mean "notification" to be a "message", but not android.app.Notification class.
And second, I don't think it's a best practise to raise new GUI when receiving a message, which would interrupt the user interaction. For details, please refer to: http://developer.android.com/training/notify-user/index.html and http://developer.android.com/design/patterns/notifications.html.
At last, if you really wanna do what you stated in your thread, I wonder why the data used to generate the show-data fragment is held in the activity. Try holding the data in an android.app.IntentService object, and then generate transfer the data to new activity, and then use android.app.Fragment.setArguments method to transfer the data from activity to fragment.
I think that this code will help you. This which you need is PendingIntent, it make transaction to desired activity.
/**
* Issues a notification to inform the user that server has sent a message.
*/
private static void generateNotification(Context context, String title,
String message) {
//get the default notification sound URI
Uri uriNotificationSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
//make intent to the application. if the application is opened just maximize it.
Intent homeIntent = new Intent(context, 'your desired activity');
homeIntent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
homeIntent, 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("eCommCongress")
.setContentText(message)
.setLights(Color.GREEN, 1500, 1500)
.setSound(uriNotificationSound)
.setAutoCancel(true)
.setContentIntent(contentIntent);
NotificationManager mNotificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(counter, mBuilder.build());
counter++;
}
It is perfectly possible and I do such a thing in one of my apps. First, you need to declare your activity as android:launchMode="singleTop",
Then, when you build you must configure your pending intent not to fire a new instance of your activity:
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent = new Intent("YOUR ACTION HERE");
intent.setClassName(this, MainActivity.class.getName());
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent resultPendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setContentIntent(resultPendingIntent);
Notification notification = mBuilder.build();
notification.defaults |= Notification.DEFAULT_VIBRATE | Notification.DEFAULT_LIGHTS;
notification.flags |= Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_AUTO_CANCEL;
mNotificationManager.notify(idNotificacion,notification);
Now all you have to do is to override your onNewIntent inside your Activity and do whatever you want with your fragment:
#Override
protected void onNewIntent(Intent intent) {
MiLog.i(getApplicationContext(),"IntentShit","new intent received");
MiLog.i(getApplicationContext(),"IntentShit","Action: "+intent.getAction());
if(intent.getAction()!=null && intent.getAction().equals("YOUR ACTION HERE"){
//DO your stuff here
}
}

I am creating notifications with following code:
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setContentTitle(messageBody)
.setAutoCancel(true)
.setSmallIcon(R.drawable.top_icon)
.setContentText(senderName)
.setTicker(senderName+" ")
.setSound(soundUri);
Intent resultIntent = new Intent(this, LoginActivity.class);
resultIntent.putExtra("gcm_username",senderName);
resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_ONE_SHOT);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(NotificationID.getID(senderName), mBuilder.build());
When user clicks the notification I am catching it with following code in loginActivity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
gcmUserId= getIntent().getStringExtra("gcm_username");
startAction(gcmUserId);
....
My problem starts here.
Scenario:
1)When app is closed user receives notifications from 2 different users
2)User clicks first notification and app starts then startAction method calls.
3)Then user clicks the second notification
But when user clicks the second notification app has already started so startAction won't be able to call again because it is in the onCreate method.How can catch second notification ?
You can handle it inside onNewIntent(). You would need to override that method inside your activity. The docs say:
This is called for activities that set launchMode to "singleTop" in their package, or if a client used the FLAG_ACTIVITY_SINGLE_TOP flag when calling startActivity(Intent). In either case, when the activity is re-launched while at the top of the activity stack instead of a new instance of the activity being started, onNewIntent() will be called on the existing instance with the Intent that was used to re-launch it.
I've created a Notification to be displayed on Status Bar.
In the notification I've added a Button, which performs some action.
To call a specific method, on button click I'm using the approach suggested here.
Code:
// Building notification - this code is present inside a Service
NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
Intent activityIntent = new Intent(this, HomeActivity.class);
activityIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, activityIntent, 0);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this).setContentTitle(fileName.toString()).setContentText("Subject")
.setSmallIcon(R.drawable.ic_app_icon).setContentIntent(pendingIntent).setAutoCancel(false);
// code to add button
Intent openListIntent = new Intent();
openListIntent.putExtra("list_intent", true);
PendingIntent listPendingIntent = PendingIntent.getActivity(this, 0, openListIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notificationBuilder.addAction(R.drawable.ic_open_list, "List", listPendingIntent);
Notification notification = notificationBuilder.build();
// Code in HomeActivity.java to perform operation on button click
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
boolean openListFlag = intent.getBooleanExtra("list_intent", false);
if (openListFlag) {
// code to perform operation
}
}
My approach is that I've passed an Extra boolean value, which is set to true, when button in notification is clicked.
But even if click on only the notification (and not on the button), still the action present in onNewIntent() is getting called.
That is, value for openListFlag is always setted as true.
How should I make sure, that operation is performed only on button click?
Just use intent action instead of extras, as suggested here:
