Put an off service button on notification of an Android App

Question

In my application I have a Service running in the background, which puts a notification in the user’s Status Bar, I would like to add a button to turn off the service, as the Waze map app does.

Answer 1

Create a Broadcastreceiver with the code needed to stop the service.
When creating the notification use the method addAction() of Notification.Builder passing a Pendigintent what’s up with this one Broadcastreceiver.

Intent intent = new Intent(this, NotificationReceiver.class);
PendingIntent pIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

Notification n  = new Notification.Builder(this)
    ...
    ...
    ...
    .setAutoCancel(true)
    .addAction(R.drawable.icon, "Parar serviço", pIntent).build();

NotificationManager notificationManager = 
  (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

notificationManager.notify(0, n);

Another way would be the Pendigintent be constructed in order to launch the service by passing a 'Extra' indicating that the service must be stopped.
The method onStartCommand() of the service checks that 'Extra' and flame stopSelf().

The Pendigintent to be used in the addAction() would be so:

Intent intent = new Intent(this, oSeuServico.class);
Intent.putExtra("Parar","Sim");
PendingIntent pIntent = PendingIntent.getService(this, 0, intent, 0);
