Get message of notification and send to the activity

Question

Here is i am creating notification with the message "wake up wake up !!!" What i want to do when notification comes on particular time and user clicks on it i need to get that message "wake up wake up !!!" and send to SnoozeActivity where i am creating custom alert dialog and i want to show that message into that dialog

        alarmNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);
       PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                new Intent(this, SnoozeActivity.class), 0);


        NotificationCompat.Builder alamNotificationBuilder = new NotificationCompat.Builder(
                this).setContentTitle("Alarm").setSmallIcon(R.drawable.ic_launcher)
                .setStyle(new NotificationCompat.BigTextStyle().bigText("wake up wake up !!!"))
                .setContentText(msg).setAutoCancel(true);


        alamNotificationBuilder.setContentIntent(contentIntent);
        alarmNotificationManager.cancelAll();
        alarmNotificationManager.notify(1, alamNotificationBuilder.build());

But i am not able to figure out how to get the message/data of clicked notification and send to next activity?

An Intent can carry data which you attach via Intent.putExtra()like this:

Intent intent = new Intent(this, SnoozeActivity.class);
intent.putExtra("com.example.mycoolapp.MYDATA", "wake up wake up !!!");

Then you continue with

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

In the onCreate() method of your SnoozeActivity, you can query the Intent for extras:

Intent intent = getIntent();
if (intent.hasExtra("com.example.mycoolapp.MYDATA"))
{
     String myText = intent.getStringExtra("com.example.mycoolapp.MYDATA");
}    

It's recommended that the keys you use for Intent extras start with your package name.

NOTE not every kind of data is possible with putExtra(), please see the documentation
