how to send push Notifications to other device in android?

Question

Using this code, i am able to send a notification to my own device.

           Intent intent = new Intent(getApplicationContext(), ContactDonor.class);
            PendingIntent pi = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
            //display text
            String body = "Please Click on this to accept!";
            String title = bloodgroup+" Required";
            Notification n = new Notification(R.drawable.ic_launcher, body , System.currentTimeMillis());
            n.setLatestEventInfo(getApplicationContext(), title, body, pi);
            n.defaults = Notification.DEFAULT_ALL;
            nm.notify(uniqueID, n);
            finish();

But now i have a screen where a person's details are displayed like: Name: ... email: ... , and there is a message box and a Request Button , on the click of that button, he should receive a notification with that particular message. How can this particular thing be done?

Answer 1

It cannot be implemented by using PUSH notifications. PUSH notification is useful when there is server-client comm is implemented where server notifies the client about the event that has occurred on server side.

What you are trying to implement indirectly is server-client architecture, where your device will act as server. If you mould your current architecture to server-client you will be able to send notification to other device. In this case also, you don't need PUSH notifications, it will be a simple server-client communication.

You can also send SMS, but that will not solve your problem. According to me, there is no other solution that you can apply to send notification.
