how to know if the app was launched by clicking on the push notification

Question

I want to know if there is a flag and parameter that can tell me if the user launched the activity/app by clicking on the push notification in the notification tray.

My code in C2DMReceiver.java

Context context = getApplicationContext();

        PackageManager manager = context.getPackageManager();
        Intent notificationIntent = manager
                .getLaunchIntentForPackage(packageName);
        notificationIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        **notificationIntent.putExtra("fromRemote", true);**

        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
                notificationIntent, 0);

        NotificationManager notificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification();
        notification.icon = R.drawable.icon;
        notification.tickerText = message;
        notification.number = badge;
        notification.when = System.currentTimeMillis();
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notification.defaults = Notification.DEFAULT_ALL;
        notification.setLatestEventInfo(context, "Draw Something", message,
                pendingIntent);
        notification.contentIntent = pendingIntent;
        notificationManager.notify(0, notification);

I tried setting

notificationIntent.putExtra("fromRemote", true);

but when the app was launched there were no extras in the intent.

my code in the onCreate function of my mainactivity

Bundle extras = getIntent().getExtras();
    if (extras != null) {
        print("onCreate - bundle has extras");
        for (String key: extras.keySet())
        {
          Log.v ("mytag", "MainActivity onCreate key =" + key);
        }
    }
    else {
        Log.v ("mytag", "onCreate - bundle has NO extras");
    }

The output i get is onCreate - bundle has NO extras. So the extras are not getting passed through.

So is there any other way?? It is so easy in iOS

Just post something to the server when your `Receiver` get called :) — Sadegh, Apr 01 '14 at 19:01

Just posting an answer so that people who visit this page get the solution.

You need to use putExtra(ID_KEY,id) when you create your Intent for starting your application, and in your onCreate() method you can use getIntent().getExtras().getInt(ID_KEY); to retrieve your passed id integer.

The passed extra could be anything, a boolean, String etc.

Except that for Firebase push 'notification' messages the app doesn't get called until the notification has already been clicked on. Which means you don't get to set any id. – Baggers Mar 29 '17 at 12:20
