Now today I am going to show how to send data when you click on the notification message.
Here I am creating two activities. One the main activity that creates the notification and the other one is used when you click on the notification.
i.e the second activity is called when you click on the notification.
Here is the main activity that sends the notification.
NotificationDemo .java
The main.xml that creates the layout for the above activity.
Now the second activity that is called when you click on the notification.
This is the layout for the second activity.
It simply contains a textview to show the passed data.
Also declare the activity in the manifest.xml
