How to add button to notifications in android?

Question

My app plays music and when users open notifications screen by swiping from the top of the screen ( or generally from the bottom right of the screen on tablets ), I want to present them a button to stop the currently playing music and start it again if they want.

I am not planning to put a widget on the user's home screen, but just into notifications. How can I do this?

You can create an intent for the action (in this case stop playing) and then add it as an action button to your notification.

Intent snoozeIntent = new Intent(this, MyBroadcastReceiver.class); snoozeIntent.setAction(ACTION_SNOOZE); snoozeIntent.putExtra(EXTRA_NOTIFICATION_ID, 0); PendingIntent snoozePendingIntent =         PendingIntent.getBroadcast(this, 0, snoozeIntent, 0);  NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, CHANNEL_ID)         .setSmallIcon(R.drawable.notification_icon)         .setContentTitle("My notification")         .setContentText("Hello World!")         .setPriority(NotificationCompat.PRIORITY_DEFAULT)         .setContentIntent(pendingIntent)         .addAction(R.drawable.ic_snooze, getString(R.string.snooze),                 snoozePendingIntent); 

Please refer to the Android documentation.
