How to choice activity to open when notification clicked

Is there way to choice the activity to start just in moment of clicking notification?
I can use setContentIntent when I build notification. But being once shown it seems not possible to set or change content intent in moment of click...

The work-around I would suggest is to direct the setContentIntent to a simple activity , which handles you specific cases in the onCreate() with the needed intent of your choice.

try this
Intent intent = new Intent(this, YOURACTIVITY.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setContentIntent(pendingIntent);

Up navigation using backstack not working while clicked from notification

I am opening an activity from notification, which opens fine.
However, I want to open it's parent activity while I click 'back button', currently it exits the application directly. I want it to navigate to HomeScreenActivity.
Here is manifest declaration -
<activity
android:name="com.discover.activities.MyTrialsActivity"
android:exported="true"
android:parentActivityName="com.discover.activities.HomeScreenActivity"
android:screenOrientation="portrait">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.discover.activities.HomeScreenActivity" />
</activity>
Here is my code to generate notification -
public static PendingIntent getAction(Activity context, int actionId) {
Intent intent;
PendingIntent pendingIntent;
intent = new Intent(context, MyTrialsActivity.class);
//intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
// Adds the back stack
//stackBuilder.addParentStack(HomeScreenActivity.class);
stackBuilder.addParentStack(HomeScreenActivity.class);
// Adds the Intent to the top of the stack
stackBuilder.addNextIntent(intent);
// Gets a PendingIntent containing the entire back stack
pendingIntent =
stackBuilder.getPendingIntent(0 /*request code */, PendingIntent.FLAG_ONE_SHOT);
/*pendingIntent = PendingIntent.getActivity(context, 0 *//* Request code *//*, intent,
PendingIntent.FLAG_UPDATE_CURRENT*//*|PendingIntent.FLAG_ONE_SHOT*//*);*/
return pendingIntent;
}
/**
* Create and show a simple notification containing the message.
*
* #param message Message to show in notification
*/
public static void sendNotification(Context context, String message, int actionId) {
PendingIntent pendingIntent = NotifUtils.getAction((Activity) context, actionId);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Title")
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setVibrate(new long[]{1000})
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

I you have everything set up correctly and it's still not working it might be that you need to uninstall and reinstall the app. It seems like some changes to the manifest are not updated properly when you run the app!

Solution -
I added my child activity as well in addParentStack(MyTrialActivity.class);
And it worked as expected.
I thought adding addNextIntent() should be doing that already, though it did not work that way..

I found the solution in android's documentation
// Intent for the activity to open when user selects the notification
Intent detailsIntent = new Intent(this, DetailsActivity.class);
// Use TaskStackBuilder to build the back stack and get the PendingIntent
PendingIntent pendingIntent =
TaskStackBuilder.create(this)
// add all of DetailsActivity's parents to the stack,
// followed by DetailsActivity itself
.addNextIntentWithParentStack(upIntent)
.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentIntent(pendingIntent);
And,
Here is the link.
Also, see this answer for more references.

Try using startActivities(Context context, Intent[] intents),
Intent homeIntent = new Intent(context, HomeScreenActivity.class);
Intent newIntent = new Intent(context, MyTrialsActivity.class);
Intent[] intents = new Intent[]{homeIntent, newIntent};
ContextCompat.startActivities(context, intents);
So we can start multiple activities at same time, so while pressing Back button it will go to Home Page instead of quiting the application.

Send Notification ID through to activity for each notfication

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);

Notification addAction creates button with no behavior

I am trying to add a button to my notification in android.
I use the addAction method in order to add an intent which supposes to open up the main activity (same as clicking the entire notification) but with an extra bundle with data.
this is what I have done so far:
notificationManager = (NotificationManager)this.getSystemService(NOTIFICATION_SERVICE);
//regular intent to view main activity
PendingIntent contentIntent = PendingIntent.getActivity(this,Constants.MAIN_ACTIVITY,
new Intent(this, MainActivity.class), 0);
//intent for viewing transaction dialog, within main activity using PURCHASE_DIALOG request code
Bundle bundle = new Bundle();
bundle.putParcelableArrayList(Constants.LIST, (java.util.ArrayList<? extends android.os.Parcelable>) list);
PendingIntent purchaseIntent = PendingIntent.getActivity(
this, Constants.PURCHASE_DIALOG,
new Intent(this, MainActivity.class), 0, bundle);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(Constants.NOTIFICATION_TOPIC)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(watchResponse.toString()))
.setAutoCancel(true)
.addAction(R.drawable.ic_launcher, "Buy", purchaseIntent)
.setContentText(message);
mBuilder.setContentIntent(contentIntent);
notificationManager.notify(NOTIFICATION_ID, mBuilder.build());
I simply expect that my onResume in MainActivity class will be called once clicking the extra action, and there i'll be able to get the bundle trough getIntent(), yet nothing happens when I click on it. the button is clicked, but the activity remains open and my application activity wont start.

I had a very similar issue but a very different solution. Pending intent is also not fired if you have declared <service android:enabled="false"></service> in your manifest.xml file.
Replace from android:enabled="false" to android:enabled="true"
This might not be a direct issue of the problem. But if you create the service in android studio using default template it automatically adds these properties to the service.
If this does not work there is a similar question you can find here:
Android Notification Action is not fired (PendingIntent)

Android Creating Notifications

I'm trying to use the code google implemented but it seems I'm missing something. Here's the code
int notificationId = 001;
// Build intent for notification content
Intent viewIntent = new Intent(this, ViewEventActivity.class);
viewIntent.putExtra(EXTRA_EVENT_ID, eventId);
PendingIntent viewPendingIntent =
PendingIntent.getActivity(this, 0, viewIntent, 0);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_event)
.setContentTitle(eventTitle)
.setContentText(eventLocation)
.setContentIntent(viewPendingIntent);
// Get an instance of the NotificationManager service
NotificationManagerCompat notificationManager =
NotificationManagerCompat.from(this);
// Build the notification and issues it with notification manager.
notificationManager.notify(notificationId, notificationBuilder.build());
When I run this, i see that my device obtains the notification, but my ViewEventActivity class is not activated when i click to the notification. I tried to add FLAG_ACTIVITY_NEW_TASK flag to my viewIntent (it was a tip in the definition of getActivity() method) but no luck there. Any help would be appreciated.

My problem was that i missed the declaration of my activity ViewEventActivity in manifest.
<activity
android:name=".ViewEventActivity" />
It's odd that application did not crash when the reference ViewEventActivity.class was not found.
