Launch Homescreen on Notification Click


Here is my Notification Builder :

public void CustomNotification() {
    // Using RemoteViews to bind custom layouts into Notification
    RemoteViews remoteViews = new RemoteViews(getPackageName(),
            R.layout.customnotification);

    // Set Notification Title
    String strtitle = getString(R.string.customnotificationtitle);
    // Set Notification Text
    String strtext = getString(R.string.customnotificationtext);

    Intent intent = new Intent(this, Main2Activity.class);
    // Send data to NotificationView Class
    intent.putExtra("title", strtitle);
    intent.putExtra("text", strtext);

    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            // Set Icon
            .setSmallIcon(R.mipmap.ic_launcher)
            // Set Ticker Message
            .setTicker(getString(R.string.customnotificationticker))
            // Dismiss Notification
            .setOngoing(true)
            // Set PendingIntent into Notification
            .setContentIntent(pIntent)
            // Set RemoteViews into Notification
            .setContent(remoteViews);

    // Locate and set the Images
    remoteViews.setImageViewResource(R.id.imagenotileft, R.mipmap.ic_launcher);
    remoteViews.setImageViewResource(R.id.imagenotiright, R.mipmap.ic_launcher);

    remoteViews.setTextViewText(R.id.title, getString(R.string.customnotificationtitle));
    remoteViews.setTextViewText(R.id.text, getString(R.string.customnotificationtext));

    // Create Notification Manager
    NotificationManager notificationmanager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    // Build Notification with Notification Manager
    notificationmanager.notify(0, builder.build());
}

Now the question is :

Is it possible to launch homescreen (device home) when the notification is clicked (or the user is taken back to the homescreen when the notification is clicked) ? If yes, then How?


Solution

  • Hey use this code to this will solve your issue mention your Activity in pendingIntent.

     private static void generateNotification(Context context, String message) {
    
        int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis();
    
        NotificationManager notificationManager = (NotificationManager)
                context.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(icon, message, when);
    
        String title = context.getString(R.string.app_name);
    
        Intent notificationIntent = new Intent(context, MainActivity.class);
        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent intent =
                PendingIntent.getActivity(context, 0, notificationIntent, 0);
        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
    
        // Play default notification sound
        notification.defaults |= Notification.DEFAULT_SOUND;
    
        //notification.sound = Uri.parse(
                               "android.resource://"
                               + context.getPackageName() 
                               + "your_sound_file_name.mp3");
    
        // Vibrate if vibrate is enabled
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationManager.notify(0, notification);      
    
    }
