                this).setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("Notification TItile").setContentText("Body");
        mBuilder.setAutoCancel(true);
        try {
            Uri uri = Uri.parse("android.resource://" + getPackageName() + "/"
                    + R.raw.yourfile);
            mBuilder.setSound(uri);
        } catch (Exception e) {
            e.printStackTrace();
        }
        // Intent resultIntent = new Intent(this, Notification.class);
        Intent resultIntent = new Intent();
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        stackBuilder.addParentStack(Notification.class);
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
                PendingIntent.FLAG_UPDATE_CURRENT);
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify((int) System.currentTimeMillis(),
                mBuilder.build());
    }

Structure of Notification in Android

1. Content title
2. Large icon
3. Content text
4. Content info
5. Small icon
6. Time   that the notification was issued. You can set an explicit value with setWhen(); if you don't it defaults to the time that the system received the notification.

Lets have a look on description 

Setting Notification custom sound - Keep your file inside raw folder of res and give URI to notification like this

        try {
            Uri uri = Uri.parse("android.resource://" + getPackageName() + "/"
                    + R.raw.yourfile);
            mBuilder.setSound(uri);
        } catch (Exception e) {
            e.printStackTrace();
        }

You can set auto cancel to remove when user tap on this       

    mBuilder.setAutoCancel(true); 

Starting your own activity while tap on notification - set your activity
name inside intent

Intent resultIntent = new Intent(this, Youractivty.class);
