public void getnotification(View view) {

       NotificationManager notificationmgr =(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
       Intent intent = new Intent(this,resultpage.class);
       PendingIntent p = PendingIntent.getService(this,(int) System.currentTimeMillis(),intent,0);


       Notification n = null;
       if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
           n = new Builder(this)
                                .setSmallIcon(R.mipmap.ic_launcher)
                               .setContentTitle("Hello android user here")
                               .setContentText("welcome to notification serrvice")
                               .setContentIntent(p)
                               .build();

           notificationmgr.notify(0,n);

       }

PackageManager.getLaunchIntentForPackage can help you find the entry activity.

    Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage(context.getPackageName());
    launchIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(launchIntent);

Its the class that implements the activity you wish to launch. LoginActivity, MainActivity, whatever it was you named it.
