Q:

Android Notification is not working

I am following a code sample somewhere from internet in which i want to start a activity when click on notification. but when i click on show notification button it gives error..
Here is my notification code.
    public void showNotification(){

                // define sound URI, the sound to be played when there's a notification
                Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);        

                // intent triggered, you can add other intent for other actions     
                Intent intent = new Intent(MainActivity.this, BusinessDetailActivity.class);
                intent.putExtra("id", 1);

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

                // this is it, we'll build the notification!
                // in the addAction method, if you don't want any icon, just set the first param to 0
                Notification mNotification = new Notification.Builder(this)
                    .setContentTitle("New Post!")
                    .setContentText("Here's an awesome update for you!")
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentIntent(pIntent)
                    .setSound(soundUri)
//                  .addAction(R.drawable.ic_launcher, "View", pIntent)
//                  .addAction(0, "Remind", pIntent)
                    .build();
                NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                mNotification.flags |=Notification.FLAG_AUTO_CANCEL;

                // If you want to hide the notification after it was selected, do the code below
                // myNotification.flags |= Notification.FLAG_AUTO_CANCEL;
                notificationManager.notify(0, mNotification);

            }

Here is my logcat.

.build() was introduced in API level 16. Use "getNotification()".
