I have app which sends notifications, I used this code for pending intent
Intent myIntent = new Intent(getApplicationContext(),MainActivity.class);
myIntent.putExtra("link",Link);
PendingIntent intent2 =
PendingIntent.getActivity(getApplicationContext(),1,myIntent,
PendingIntent.FLAG_ONE_SHOT);
and it worked nice for the first time, but I use this piece of code inside a method that invokes every 1 minute.
The problem is that the link variable changes from one to another.
and when I get the data in the MainActivity I found the last link only, all the notifications created has the last link.
and I don't know how to avoid this.
You are sending the same request code for your pending intents. These codes are defined as the 2nd parameter of your Pending intent declaration
Change
PendingIntent intent2 =
PendingIntent.getActivity(getApplicationContext(),1,myIntent,
PendingIntent.FLAG_ONE_SHOT);
To:
PendingIntent intent2 =
PendingIntent.getActivity(getApplicationContext(),UNIQUE_INT_VALUE_FOR_EVERY_CALL,myIntent,
PendingIntent.FLAG_ONE_SHOT);
If you use the same id, the intent will be reused and you will only get the last data rather than getting new data for every call.
Try This,
PendingIntent contentIntent = PendingIntent.getActivity(GCMNotificationIntentService.this, 0, notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);
In Kotlin
Make a notification
val builder = NotificationCompat.Builder(context, CHANNEL_ID)
For one and more just change the request Code number:
val pendingIntent = PendingIntent.getActivity(context,
System.currentTimeMillis().toInt(),intent, 0)
then
builder.setContentIntent(pendingIntent)
I have a JSON message being sent to a listening service in my first Android app (read: pelase be gentle!) that is mapped to an object that implements Parcelable. The deserialized object is used to display a notification, with an intent that is meant to launch another activity displaying the full data in a layout.
Using the deserialized object I'm able to display the information in the notification without issue. The code in the notification to launch the secondary activity:
Intent intent = new Intent(this, SecondaryActivity.class);
intent.putExtra("objData", myObj);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setContentTitle(myObj.getTitle())
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(myObj.getAbstract()))
.setContentText(myObj.getAbstract());
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
In the SecondaryActivity I unwrap the parcel like so:
MyObject myObj = getIntent().getParcelableExtra("objData");
and use its data to fill in areas of the layout.
This works great on the first notification. On subsequent notifications, the notification looks correct but the parcelable data sent to SecondaryActivity is not updated (the content appears to the same as the first notification).
I'm assuming I'm missing something obvious that is preventing the parcelable object from being updated. Can you help?
When creating the pending intent you could try adding the flag FLAG_CANCEL_CURRENT or FLAG_UPDATE_CURRENT
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
I want to pass a long value using a PendingIntent something like this
Intent intentForPending = new Intent(context, NewBlaBlaActivity.class);
long courseId = 15252;
intentForPending.putExtra("courseId", courseId);
intentForPending.putExtra("isFromPushNotification", true);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intentForPending, 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
context).setSmallIcon(R.drawable.appicon)
.setContentTitle("BlaBla")
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
.setContentText(message)
.setAutoCancel(true);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
And get the value as below
Intent intent = getIntent();
if(intent.getBooleanExtra("isFromPushNotification", false)) {
long courseId = intent.getLongExtra("courseId", 0);
}
But I always get 0 from the intent. The weird thing is while I can get the boolean value with 'isFromPushNotification' key from the intent, I cannot get the long value from the same intent.
This drives me crazy. As you can see, it is a PushNotification and this code runs when I tap on the notification.
I tried all the way I can get from the forums and questions in stackoverflow, adding L suffix on def and original value on long objects. But I think PendingIntent is wet blanket.
I am waiting for your godlike advices. Thanks!
If you are going to use extras with a PendingIntent, always use a flag in the last parameter of the PendingIntent factory method (getActivity() in your case). Probably you want FLAG_UPDATE_CURRENT, to indicate to replace any existing PendingIntent contents with the new extras.
My MainActicity starts RefreshService with a Intent which has a boolean extra called isNextWeek.
My RefreshService makes a Notification which starts my MainActivity when the user clicks on it.
this looks like this:
Log.d("Refresh", "RefreshService got: isNextWeek: " + String.valueOf(isNextWeek));
Intent notificationIntent = new Intent(this, MainActivity.class);
notificationIntent.putExtra(MainActivity.IS_NEXT_WEEK, isNextWeek);
Log.d("Refresh", "RefreshService put in Intent: isNextWeek: " + String.valueOf(notificationIntent.getBooleanExtra(MainActivity.IS_NEXT_WEEK,false)));
pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
builder = new NotificationCompat.Builder(this).setContentTitle("Title").setContentText("ContentText").setSmallIcon(R.drawable.ic_notification).setContentIntent(pendingIntent);
notification = builder.build();
// Hide the notification after its selected
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(NOTIFICATION_REFRESH, notification);
As you can see the notificationIntent should have the booleanextra IS_NEXT_WEEK with the value of isNextWeek which is put in the PendingIntent.
When I click now this Notification I always get false as value of isNextWeek
This is the way I get the value in the MainActivity:
isNextWeek = getIntent().getBooleanExtra(IS_NEXT_WEEK, false);
Log:
08-04 00:19:32.500 13367-13367/de.MayerhoferSimon.Vertretungsplan D/Refresh: MainActivity sent: isNextWeek: true
08-04 00:19:32.510 13367-13573/de.MayerhoferSimon.Vertretungsplan D/Refresh: RefreshService got: isNextWeek: true
08-04 00:19:32.510 13367-13573/de.MayerhoferSimon.Vertretungsplan D/Refresh: RefreshService put in Intent: isNextWeek: true
08-04 00:19:41.990 13367-13367/de.MayerhoferSimon.Vertretungsplan D/Refresh: MainActivity.onCreate got: isNextWeek: false
When I directly start the MainActivity with an Intent with the ìsNextValue` like this:
Intent i = new Intent(this, MainActivity.class);
i.putExtra(IS_NEXT_WEEK, isNextWeek);
finish();
startActivity(i);
everything works fine and I get true when isNextWeek is true.
What do I make wrong that there is always a false value?
UPDATE
this solves the problem:
https://stackoverflow.com/a/18049676/2180161
Quote:
My suspicion is that, since the only thing changing in the Intent is
the extras, the PendingIntent.getActivity(...) factory method is
simply re-using the old intent as an optimization.
In RefreshService, try:
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);
See:
http://developer.android.com/reference/android/app/PendingIntent.html#FLAG_CANCEL_CURRENT
UPDATE 2
See answer below why it is better to use PendingIntent.FLAG_UPDATE_CURRENT.
Using PendingIntent.FLAG_CANCEL_CURRENT not a good solution because of inefficient use of memory. Instead use PendingIntent.FLAG_UPDATE_CURRENT.
Use also Intent.FLAG_ACTIVITY_SINGLE_TOP (the activity will not be launched if it is already running at the top of the history stack).
Intent resultIntent = new Intent(this, FragmentPagerSupportActivity.class).
addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
resultIntent.putExtra(FragmentPagerSupportActivity.PAGE_NUMBER_KEY, pageNumber);
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
this,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
Then:
#Override
protected void onCreate(Bundle savedInstanceState) {
try {
super.onCreate(savedInstanceState);
int startPageNumber;
if ( savedInstanceState != null)
{
startPageNumber = savedInstanceState.getInt(PAGE_NUMBER_KEY);
//so on
It should work now.
If you still have not expected behaviour, try to implement void onNewIntent(Intent intent) event handler, that way you can access the new intent that was called for the activity (which is not the same as just calling getIntent(), this will always return the first Intent that launched your activity.
#Override
protected void onNewIntent(Intent intent) {
int startPageNumber;
if (intent != null) {
startPageNumber = intent.getExtras().getInt(PAGE_NUMBER_KEY);
} else {
startPageNumber = 0;
}
}
I think you need to update the Intent when you receive a new one by overriding onNewIntent(Intent) in your Activity. Add the following to your Activity:
#Override
public void onNewIntent(Intent newIntent) {
this.setIntent(newIntent);
// Now getIntent() returns the updated Intent
isNextWeek = getIntent().getBooleanExtra(IS_NEXT_WEEK, false);
}
Edit:
This is needed only if your Activity has already been started when the intent is received. If your activity is started (and not just resumed) by the intent, then the problem is elsewhere and my suggestion may not fix it.
Following code should work:-
int icon = R.drawable.icon;
String message = "hello";
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.putExtra("isNexWeek", true);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, pIntent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
In MainActivity onCreate:
if (getIntent().getExtras() != null && getIntent().getExtras().containsKey("isNextWeek")) {
boolean isNextWeek = getIntent().getExtras().getBoolean("isNextWeek");
}
So the actual reason is that the PendingIntent will cache the previous intent if the intents only differ in their extras. In my situation no combination of PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_CANCEL_CURRENT solves this as either the old intent will be replaced or the new one will stay the same as the initial one.
You need to ensure that Android cannot cache the Intents behind the PendingIntent. The solution for me is to make them differ in their data attribute.
so in the original posters code you would need to ensure that the data attribute is unique per each combination of extras that you are attaching.
Intent notificationIntent = new Intent(this, MainActivity.class);
notificationIntent.putExtra(MainActivity.IS_NEXT_WEEK, isNextWeek);
notificationIntent.setData(Uri.parse("myapp://nextWeek/" + (isNextWeek ? "1" : "0"))
Alternatively you could probably also just add a uuid to the data uri (however, if you have lots and lots of notifications, it might be nice to cache them
I can find a way to send parameters to my activity from my notification.
I have a service that creates a notification. When the user clicks on the notification I want to open my main activity with some special parameters. E.g an item id, so my activity can load and present a special item detail view. More specific, I'm downloading a file, and when the file is downloaded I want the notification to have an intent that when clicked it opens my activity in a special mode. I have tried to use putExtra on my intent, but cant seem to extract it, so I think I'm doing it wrong.
Code from my service that creates the Notification:
// construct the Notification object.
final Notification notif = new Notification(R.drawable.icon, tickerText, System.currentTimeMillis());
final RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification_layout);
contentView.setImageViewResource(R.id.image, R.drawable.icon);
contentView.setTextViewText(R.id.text, tickerText);
contentView.setProgressBar(R.id.progress,100,0, false);
notif.contentView = contentView;
Intent notificationIntent = new Intent(context, Main.class);
notificationIntent.putExtra("item_id", "1001"); // <-- HERE I PUT THE EXTRA VALUE
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notif.contentIntent = contentIntent;
nm.notify(id, notif);
Code from my Activity that tries to fetch the extra parameter from the notification:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Bundle extras = getIntent().getExtras();
if(extras != null){
Log.i( "dd","Extra:" + extras.getString("item_id") );
}
The extras is always null and I never gets anything into my log.
Btw... the onCreate is only run when my activity starts, if my activity is already started I also want to collect the extras and present my activity according to the item_id I receive.
Any ideas?
Take a look at this guide (creating a notification) and to samples ApiDemos "StatusBarNotifications" and "NotificationDisplay".
For managing if the activity is already running you have two ways:
Add FLAG_ACTIVITY_SINGLE_TOP flag to the Intent when launching the activity, and then in the activity class implement onNewIntent(Intent intent) event handler, that way you can access the new intent that was called for the activity (which is not the same as just calling getIntent(), this will always return the first Intent that launched your activity.
Same as number one, but instead of adding a flag to the Intent you must add "singleTop" in your activity AndroidManifest.xml.
If you use intent extras, remeber to call PendingIntent.getActivity() with the flag PendingIntent.FLAG_UPDATE_CURRENT, otherwise the same extras will be reused for every notification.
I had the similar problem my application displays message notifications.
When there are multiple notifications and clicking each notification it displays that notification detail in a view message activity. I solved the problem of same extra parameters is being received in view message intent.
Here is the code which fixed this.
Code for creating the notification Intent.
Intent notificationIntent = new Intent(getApplicationContext(), viewmessage.class);
notificationIntent.putExtra("NotificationMessage", notificationMessage);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingNotificationIntent = PendingIntent.getActivity(getApplicationContext(),notificationIndex,notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.setLatestEventInfo(getApplicationContext(), notificationTitle, notificationMessage, pendingNotificationIntent);
Code for view Message Activity.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
onNewIntent(getIntent());
}
#Override
public void onNewIntent(Intent intent){
Bundle extras = intent.getExtras();
if(extras != null){
if(extras.containsKey("NotificationMessage"))
{
setContentView(R.layout.viewmain);
// extract the extra-data in the Notification
String msg = extras.getString("NotificationMessage");
txtView = (TextView) findViewById(R.id.txtMessage);
txtView.setText(msg);
}
}
}
Maybe a bit late, but:
instead of this:
public void onNewIntent(Intent intent){
Bundle extras = intent.getExtras();
Log.i( "dbg","onNewIntent");
if(extras != null){
Log.i( "dbg", "Extra6 bool: "+ extras.containsKey("net.dbg.android.fjol"));
Log.i( "dbg", "Extra6 val : "+ extras.getString("net.dbg.android.fjol"));
}
mTabsController.setActiveTab(TabsController.TAB_DOWNLOADS);
}
Use this:
Bundle extras = getIntent().getExtras();
if(extras !=null) {
String value = extras.getString("keyName");
}
Encounter same issue here.
I resolve it by using different request code, use same id as notification, while creating PendingIntent. but still don't know why this should be done.
PendingIntent contentIntent = PendingIntent.getActivity(context, **id**, notificationIntent, 0);
notif.contentIntent = contentIntent;
nm.notify(**id**, notif);
After reading some email-lists and other forums i found that the trick seems to add som unique data to the intent.
like this:
Intent notificationIntent = new Intent(Main.this, Main.class);
notificationIntent.putExtra("sport_id", "sport"+id);
notificationIntent.putExtra("game_url", "gameURL"+id);
notificationIntent.setData((Uri.parse("foobar://"+SystemClock.elapsedRealtime())));
I dont understand why this needs to be done, It got something to do with the intent cant be identified only by its extras...
I tried everything but nothing worked.
eventually came up with following solution.
1- in manifest add for the activity
android:launchMode="singleTop"
2- while making pending intent do the following, use bundle instead of directly using intent.putString() or intent.putInt()
Intent notificationIntent = new Intent(getApplicationContext(), CourseActivity.class);
Bundle bundle = new Bundle();
bundle.putString(Constants.EXAM_ID,String.valueOf(lectureDownloadStatus.getExamId()));
bundle.putInt(Constants.COURSE_ID,(int)lectureDownloadStatus.getCourseId());
bundle.putString(Constants.IMAGE_URL,lectureDownloadStatus.getImageUrl());
notificationIntent.putExtras(bundle);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(),
new Random().nextInt(), notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
AndroidManifest.xml
Include launchMode="singleTop"
<activity android:name=".MessagesDetailsActivity"
android:launchMode="singleTop"
android:excludeFromRecents="true"
/>
SMSReceiver.java
Set the flags for the Intent and PendingIntent
Intent intent = new Intent(context, MessagesDetailsActivity.class);
intent.putExtra("smsMsg", smsObject.getMsg());
intent.putExtra("smsAddress", smsObject.getAddress());
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, notification_id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
MessageDetailsActivity.java
onResume() - gets called everytime, load the extras.
Intent intent = getIntent();
String extraAddress = intent.getStringExtra("smsAddress");
String extraBody = intent.getStringExtra("smsMsg");
Hope it helps, it was based on other answers here on stackoverflow, but this is the most updated that worked for me.
It's easy,this is my solution using objects!
My POJO
public class Person implements Serializable{
private String name;
private int age;
//get & set
}
Method Notification
Person person = new Person();
person.setName("david hackro");
person.setAge(10);
Intent notificationIntent = new Intent(this, Person.class);
notificationIntent.putExtra("person",person);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.notification_icon)
.setAutoCancel(true)
.setColor(getResources().getColor(R.color.ColorTipografiaAdeudos))
.setPriority(2)
.setLargeIcon(bm)
.setTicker(fotomulta.getTitle())
.setContentText(fotomulta.getMessage())
.setContentIntent(PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT))
.setWhen(System.currentTimeMillis())
.setContentTitle(fotomulta.getTicketText())
.setDefaults(Notification.DEFAULT_ALL);
New Activity
private Person person;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notification_push);
person = (Person) getIntent().getSerializableExtra("person");
}
Good Luck!!
In your notification implementation, use a code like this:
NotificationCompat.Builder nBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
...
Intent intent = new Intent(this, ExampleActivity.class);
intent.putExtra("EXTRA_KEY", "value");
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
nBuilder.setContentIntent(pendingIntent);
...
To Get Intent extra values in the ExampleActivity, use the following code:
...
Intent intent = getIntent();
if(intent!=null) {
String extraKey = intent.getStringExtra("EXTRA_KEY");
}
...
VERY IMPORTANT NOTE: the Intent::putExtra() method is an Overloaded one. To get the extra key, you need to use Intent::get[Type]Extra() method.
Note: NOTIFICATION_ID and NOTIFICATION_CHANNEL_ID are an constants declared in ExampleActivity
After doing some search i got solution from android developer guide
PendingIntent contentIntent ;
Intent intent = new Intent(this,TestActivity.class);
intent.putExtra("extra","Test");
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(ArticleDetailedActivity.class);
contentIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
To Get Intent extra value in Test Activity class you need to write following code :
Intent intent = getIntent();
String extra = intent.getStringExtra("extra") ;
Please use as PendingIntent while showing notification than it will be resolved.
PendingIntent intent = PendingIntent.getActivity(this, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Add PendingIntent.FLAG_UPDATE_CURRENT as last field.
G'day,
I too can say that I tried everything mentioned in these posts and a few more from elsewhere.
The #1 problem for me was that the new Intent always had a null bundle.
My issue was in focusing too much on the details of "have I included .this or .that".
My solution was in taking a step back from the detail and looking at the overall structure of the notification. When I did that I managed to place the key parts of the code in the correct sequence.
So, if you're having similar issues check for:
1. Intent notificationIntent = new Intent(MainActivity.this, NotificationActivity.class);
2a. Bundle bundle = new Bundle();
//I like specifying the data type much better. eg bundle.putInt
2b. notificationIntent.putExtras(bundle);
3. PendingIntent contentIntent = PendingIntent.getActivity(MainActivity.this, WIZARD_NOTIFICATION_ID, notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
4. NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
5. NotificationCompat.Builder nBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_notify)
.setContentTitle(title)
.setContentText(content)
.setContentIntent(contentIntent)
.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE)
.setAutoCancel(false)//false is standard. true == automatically removes the notification when the user taps it.
.setColor(getResources().getColor(R.color.colorPrimary))
.setCategory(Notification.CATEGORY_REMINDER)
.setPriority(Notification.PRIORITY_HIGH)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC);
notificationManager.notify(WIZARD_NOTIFICATION_ID, nBuilder.build());
With this sequence I get a valid bundle.
If you use
android:taskAffinity="myApp.widget.notify.activity"
android:excludeFromRecents="true"
in your AndroidManifest.xml file for the Activity to launch, you have to use the following in your intent:
Intent notificationClick = new Intent(context, NotifyActivity.class);
Bundle bdl = new Bundle();
bdl.putSerializable(NotifyActivity.Bundle_myItem, myItem);
notificationClick.putExtras(bdl);
notificationClick.setData(Uri.parse(notificationClick.toUri(Intent.URI_INTENT_SCHEME) + myItem.getId()));
notificationClick.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK); // schließt tasks der app und startet einen seperaten neuen
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(NotifyActivity.class);
stackBuilder.addNextIntent(notificationClick);
PendingIntent notificationPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(notificationPendingIntent);
Important is to set unique data e.g. using an unique id like:
notificationClick.setData(Uri.parse(notificationClick.toUri(Intent.URI_INTENT_SCHEME) + myItem.getId()));
