What methods are called when opening app from push notification

I'm trying to figure out what methods are called when my app is opened by tapping on a push-notification banner. The app appears to re-launch?

you can use pending Intent, like this:
val intent = Intent(this#MyFirebaseMessagingService, NextActivity::class.java)
val pendingIntent = PendingIntent.getActivity(this, 101, intent,
PendingIntent.FLAG_UPDATE_CURRENT)
and set pendingIntent to your notification.Builder.

Click on notification and then go to next detail page where there is also the detail of that are present

I am the student of computer science last semester student.
I have problem:
I set my Android Application that receive notification from online database of job finder web application.When new entry occur then notification comes here on Android App.
So now i want if i click that notification then there will be a page open in which the detail of that job will present.
so please guid me i have only few days to submit my final year project.
I will be very thankfull.

Have a look at the Android Developers Guide. There they describe to set up a PendingIntent to react to the click on the notification.
PendingIntent resultPendingIntent;
...
mBuilder.setContentIntent(resultPendingIntent); // Code comes directly from this Developer Guide

You have to use Pending Intent to open page when click on Notification.
// prepare intent which is triggered if the
// notification is selected
Intent intent = new Intent(this, YourActivityToBeOpen.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
You can find more details here.

To create Notification :
NotificationManager mgr = (NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification note = new Notification(R.drawable.stat_notify_chat,
"Android Example Status message!",
System.currentTimeMillis());
// This pending intent will open after notification click
Intent i = new Intent(this, NotifyMessage.class);
PendingIntent i = PendingIntent.getActivity(this, 0, i, 0);
note.setLatestEventInfo(this, "Android Example Notification Title",
"This is the android example notification message", i);
// After uncomment this line you will see number of notification arrived
// note.number=2;
mgr.notify(NOTIFY_ME_ID, note);
Intent i = new Intent(this, NotifyMessage.class);
PendingIntent i = PendingIntent.getActivity(this, 0, i, 0);
Its manage your navigation after click on notification. If you want no navigation then use :
Intent i = new Intent();
PendingIntent i = PendingIntent.getActivity(this, 0, i, 0);
I hope it will help.

Save to DB after clear the push notification android

I am working with push notification and I have one problem.
When I click in the received notification my code launch a new intent with an activity.
I use:
Intent i = new Intent(getApplicationContext(), DemoActivity.class);
i.putExtra("msg",msg);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
i, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(contentIntent);
ITS OK FOR ME
But if I want only save this notification in SQLite how can I pass the message?
I know that with:
Intent bd = new Intent(getApplicationContext(), AbaseDatos.class);
bd.putExtra("msg",msg);
PendingIntent contentIntentbd = PendingIntent.getActivity(this, 0,
bd, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setDeleteIntent(contentIntentbd);
Call a new activity when clear the notification, but the new activity open the layout.
I dont want any new activity be launched. Its possible launch a javaclass with an Intent?
Any idea?

You can launch a service with an intent.

Android - Track Notification onclicked

I want to start a activity when users clicked on notification but there are no onclicked event for notification (?), so how can we know when the notification is clicked?
Thanks!

Look into PendingIntent setup there.
The PendingIntent will get called when you click the notification.

Intent notificationIntent = new Intent(this, MyClass.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notificationIntent will be called when notification is clicked.

Android notification click

I am running a service which is popping notification on getting a new task. If I close my app it's running in the background and pop up a notification. What I would like to do is, when I click on that notification, open the app. Can I do that ? How ?

You can do this by adding an intent to your notification:
Intent notificationIntent = new Intent(context, YourAppActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
notification.setLatestEventInfo(context, "headline", "body msg", contentIntent);
notifcationMgr.notify(id, notification);
Just replace YourAppActivity with the activity you want to launch.
