How to send Notification through Firebase console including Custom data?

I have to send a URL in notification and I want upon clicking the notification, the link will be opened immediately by Chrome. Currently, when I click the notification, it only opens my app.
What changes do I have to implement in this code for my desired behavior?
private void sendNotification(String messageBody, String title) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(title)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}

sharedpreferences in service does not save when app is not open

When I send notification and app does not open already,I cant see my notification on listview in mainactivity.When I send notification and app already is open,I see on listview.How can I see notifications on listview everytime I send notification?
my service
private void sendNotification(String messageBody) {
SharedPreferences a=getSharedPreferences("noti",MODE_PRIVATE);
SharedPreferences.Editor editor=a.edit();
editor.putInt("i",a.getInt("i",0)+1);
editor.putString(String.valueOf(a.getInt("i",0)+1),messageBody);
editor.apply();
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.farmer)
.setContentTitle("Zengin Çiftçi")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
my mainactivity
a=getSharedPreferences("noti",MODE_PRIVATE);
for(int i=a.getInt("i",0);i>0;i--){
liste.add(a.getString(String.valueOf(i),""));
}

How can I catch the click on notification?

I need to call some methods after clicking the notification. My notification has a pendingIntent that opens a browser. But I also have to do some other things AFTER user clicks it. Oh, and I must admit that I get my notifications from GCM(push).
Intent intent;
intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(urlString));
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(mBitmap)
.setContentTitle(title)
.setDefaults(Notification.DEFAULT_ALL)
.setContentText(body)
.setAutoCancel(true);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
Notification myNotification = notificationBuilder.build();
myNotification.setLatestEventInfo(getBaseContext(), title, body, pendingIntent);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(TAG, myNotification);

To handle the click on the notification itself (not an action) you need to specify a ContentIntent as following:
notificationBuilder.setContentIntent(PendingIntent.getActivity(
context,
0,
new Intent(context, YourActivity.class)
.putExtra("extra_something", something)
.setData(Uri.parse("pass an uri if needed")),
PendingIntent.FLAG_UPDATE_CURRENT
))
Hope it helps.

Click event not working on Heads-up notification

Nothing happens on clicking Accept or Reject button of the head-ups notification.
But when the head-up notification disappear and from clicking Accept and Reject from the notification panel is working.
Testing on Android 5.1.0.
Intent acceptIntent = new Intent(this, NotificationReceiver.class);
acceptIntent.setAction("com.android.test.Accept");
PendingIntent acceptPendingIntent = PendingIntent.getBroadcast(TestApplication.getAppContext(), 12345, acceptIntent, PendingIntent.FLAG_CANCEL_CURRENT);
Intent rejectIntent = new Intent(this, NotificationReceiver.class);
rejectIntent.setAction("com.android.test.Reject");
PendingIntent rejectPendingIntent = PendingIntent.getBroadcast(TestApplication.getAppContext(), 12345, rejectIntent, PendingIntent.FLAG_CANCEL_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(R.drawable.fundu);
builder.setContentTitle("Test Notification");
builder.setContentText("Hello");
builder.setAutoCancel(true);
builder.setVisibility(NotificationCompat.VISIBILITY_PUBLIC);
builder.setCategory(NotificationCompat.CATEGORY_SERVICE);
builder.setDefaults(NotificationCompat.DEFAULT_ALL);
builder.setPriority(NotificationCompat.PRIORITY_MAX);
builder.addAction(R.drawable.ic_check_icon, "Accept", acceptPendingIntent);
builder.addAction(R.drawable.ic_action_close, "Reject", rejectPendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, builder.build());

Just setting the vibration, makes it working fine.
builder.setVibrate(new long[0]);

The key is to call setContentIntent on the Notification Builder and passing it a PendingIntent. The Full code with comments explaining each step is included below. See the part named "THIS IS THE PERTINENT PART" (The Full code is included for completeness sake.)
// Use Notification Builder to start things off
// There are other ways of acquiring a Notification Builder; this is just an example
String channelId = "channelId";
String title = "title";
String body = "body";
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context, channelId);
notificationBuilder
.setSmallIcon(R.drawable.ic_alarm)
.setContentTitle(title)
.setContentText(body);
//--------------- THIS IS THE PERTINENT PART ---------------
// Prepare Intent for creating PendingIntent
Intent intent = new Intent(context, ActivityToStart.class);
// Create Pending Intent
int requestCode= 1234; // requestCode has to be a unique ID for EACH PendingIntent
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addNextIntent(intent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(
requestCode,
PendingIntent.FLAG_UPDATE_CURRENT // use to prevent re-using current Activity Intent
);
notificationBuilder.setContentIntent(pendingIntent);
// Finally, create the Notification
Notification notification = notificationBuilder.build();

How to ask Yes/No in notification and then launch the app and run corresponding method? Source code and screenshot attached

I have prepared a simple test app which posts a notification on a button click:
The source code from MainActivity.java creating the notification is displayed below:
Button showButton = (Button) findViewById(R.id.show);
showButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent appIntent = new Intent(mContext, MainActivity.class);
appIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
appIntent.putExtra("my_data", 12345);
String question = getString(R.string.the_question);
PendingIntent contentIntent = PendingIntent.getActivity(mContext, 0, appIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification = new NotificationCompat.Builder(mContext)
.setContentTitle(question)
.setContentText(question)
.setTicker(question)
.setWhen(System.currentTimeMillis())
.setContentIntent(contentIntent)
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setSmallIcon(R.drawable.ic_launcher)
.build();
mManager.notify(NOTIFY_ID, notification);
}
});
My question is: how to modify the notification, so that the user is asked a Yes/No question (in this case: "Do you want to open the car?") and - after she selects Yes or No to launch the same app and run a corresponding method in it (in this case: openCar() or closeCar() method).
I probably should use NotificationCompat.Action.Builder - but how exactly?
Also I am not really sure if this code is the correct code for launching an app from notification and what flags should I use:
Intent appIntent = new Intent(mContext, MainActivity.class);
appIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
And finally I wonder if hardcodidng some random number in NOTIFY_ID is the correct way when posting notifications?

Here is a source code I used for notification with Login/Register action.
private void sendNotification(String message, String title) {
try {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Intent secondActivityIntent = new Intent(this, SecondActivity.class);
PendingIntent secondActivityPendingIntent = PendingIntent.getActivity(this, 0 , secondActivityIntent, PendingIntent.FLAG_ONE_SHOT);
Intent thirdActivityIntent = new Intent(this, ThridActivity.class);
PendingIntent thirdActivityPendingIntent = PendingIntent.getActivity(this, 0 , thirdActivityIntent, PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_3d_rotation_white_36dp)
.setContentTitle(title)
.setContentText(message)
.addAction(R.drawable.ic_lock_open_cyan_600_24dp,"Login",secondActivityPendingIntent)
.addAction(R.drawable.ic_lock_pink_700_24dp,"Register",thirdActivityPendingIntent)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
} catch (Exception e) {
e.printStackTrace();
}
}
To use it: simply call this method sendNotification(String yourMessage, String yourTitle)
e.g. sendNotification("Hello Message", "Hello Title")
Here is a snapshot of the output

Notify user on pending Intent.. an example is here..
public void notifyUser() {
NotificationManager notificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent = new Intent(HappyActivity.this, NotificationDialog.class);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
// use the flag FLAG_UPDATE_CURRENT to override any notification already
// there
pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification = new Notification(R.drawable.ic_launcher,
"Question.....?????", System.currentTimeMillis());
notification.flags = Notification.FLAG_AUTO_CANCEL
| Notification.DEFAULT_LIGHTS | Notification.DEFAULT_SOUND;
notification.setLatestEventInfo(this, "title",
"Explanation of question..", pendingIntent);
// 10 is a random number I chose to act as the id for this notification
notificationManager.notify(10, notification);
}
