body: <p>Why is <code>Intent</code> from notification null?</p>
  
  <pre><code>Intent resultIntent = new Intent(context, myclass.class);
          resultIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
                  Intent.FLAG_ACTIVITY_SINGLE_TOP);
          Bundle extras=new Bundle();
          extras.putString("key","value");
          PendingIntent resultPendingIntent =
                  PendingIntent.getActivity(
                          context,
                          0,
                          resultIntent,
                          PendingIntent.FLAG_UPDATE_CURRENT
                  );
              NotificationCompat.Builder n = new NotificationCompat.Builder(context)
                      .setContentTitle("test")
                      .setContentText(text)
                      .setSound(sound)
                      .setContentIntent(resultPendingIntent)
                      .setAutoCancel(true)
                      .setExtras(extras)
                      .setSmallIcon(android.R.drawable.ic_media_play);
              NotificationManager notificationManager = (NotificationManager) context.getSystemService((context.getApplicationContext().NOTIFICATION_SERVICE));
