Answer 1

public static void notifyUser(Activity activity, String header,
        String message) {
    NotificationManager notificationManager = (NotificationManager) activity
            .getSystemService(Activity.NOTIFICATION_SERVICE);
    Intent notificationIntent = new Intent(
            activity.getApplicationContext(), YourActivityToLaunch.class);
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(activity);
    stackBuilder.addParentStack(YourActivityToLaunch.class);
    stackBuilder.addNextIntent(notificationIntent);
    PendingIntent pIntent = stackBuilder.getPendingIntent(0,
            PendingIntent.FLAG_UPDATE_CURRENT);
    Notification notification = new Notification.Builder(activity)
            .setContentTitle(header)
            .setContentText(message)
            .setDefaults(
                    Notification.DEFAULT_SOUND
                            | Notification.DEFAULT_VIBRATE)
            .setContentIntent(pIntent).setAutoCancel(true)
            .setSmallIcon(drawable.notification_icon).build();
    notificationManager.notify(2, notification);
}

Answer 2

use this:

    Notification mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ic_music)
                    .setContentTitle(songName).build();


    mBuilder.contentIntent=  PendingIntent.getActivity(this, 0,
            new Intent(this, MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);

contentIntent will take care of openning activity when notification clicked

Use my example...

 public void createNotification() {
        NotificationManager notificationManager = (NotificationManager) 
              getSystemService(NOTIFICATION_SERVICE);
        Notification notification = new Notification(R.drawable.icon,
            "message", System.currentTimeMillis());
        // Hide the notification after its selected
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        Vibrator vibrator = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
        long[] pattern = { 0, 100, 600, 100, 700};
        vibrator.vibrate(pattern, -1);
     Intent intent = new Intent(this, Main.class);
     PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
     String sms = getSharedPreferences("SMSPREF", MODE_PRIVATE).getString("incoming", "EMPTY");
        notification.setLatestEventInfo(this, "message" ,
            sms, activity);
        notification.number += 1;
        notificationManager.notify(0, notification);

      }

public void addNotification()
{
    NotificationCompat.Builder mBuilder=new NotificationCompat.Builder(MainActivity.this);
    mBuilder.setSmallIcon(R.drawable.email);
    mBuilder.setContentTitle("Notification Alert, Click Me!");
    mBuilder.setContentText("Hi,This notification for you let me check");
    Intent notificationIntent = new Intent(this,MainActivity.class);
    PendingIntent conPendingIntent = PendingIntent.getActivity(this,0,notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);

    mBuilder.setContentIntent(conPendingIntent);

    NotificationManager manager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(0,mBuilder.build());
    Toast.makeText(MainActivity.this, "Notification", Toast.LENGTH_SHORT).show();

}

See below code. I am using that and it is opening my HomeActivity.

    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    Intent notificationIntent = new Intent(context, HomeActivity.class);

    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;
    notificationManager.notify(0, notification);

Use below code for create notification for open activity. It works for me. For full code

 Intent myIntent = new Intent(context, DoSomething.class);
 PendingIntent pendingIntent = PendingIntent.getActivity(
        context, 
        0, 
        myIntent, 
        Intent.FLAG_ACTIVITY_NEW_TASK);

 myNotification = new NotificationCompat.Builder(context)
   .setContentTitle("Exercise of Notification!")
   .setContentText("Do Something...")
   .setTicker("Notification!")
   .setWhen(System.currentTimeMillis())
   .setContentIntent(pendingIntent)
   .setDefaults(Notification.DEFAULT_SOUND)
   .setAutoCancel(true)
   .setSmallIcon(R.drawable.ic_launcher)
   .build();

 notificationManager = 
   (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
 notificationManager.notify(MY_NOTIFICATION_ID, myNotification);
