Multiple Intents for Notifications in android

i am sending notifications using following code

NotificationManager mNotificationManager = (NotificationManager)
                mContext.getSystemService(Context.NOTIFICATION_SERVICE);

        PendingIntent contentIntent = PendingIntent.getActivity(mContext, 0,
                i, PendingIntent.FLAG_ONE_SHOT);

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(mContext)
                        .setSmallIcon(R.drawable.ic_launcher)
                        .setContentTitle(title)
                        .setDefaults(Notification.DEFAULT_SOUND)
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText(msg))
                        .setContentText(msg);

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.cancel(Constants.NOTIF_ID);
        mNotificationManager.notify(Constants.NOTIF_ID, mBuilder.build());

I have different scenarios for now. I want it to work like if the app is online or is in background, wherever i stand in activity list, i remove all activities and go to my mainactivity

Something like

                        Intent i = new Intent(ctx, MainActivity.class);
                        i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                        i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
                        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

But if my app is not in background or is running, then it should start with SplashActivity

                        Intent i = new Intent(ctx, SplashActivity.class);
                        i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                        i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
                        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
