http://blog.csdn.net/chentravelling/article/details/51260063

一.notification

 pushMessageButton = (Button)findViewById(R.id.pushMessage);
 final Bitmap largeIcon = ((BitmapDrawable) getResources().getDrawable(R.drawable.stefan)).getBitmap();
 final NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
 pushMessageButton.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {
         PendingIntent pendingIntent = PendingIntent.getActivity(BaiDuMapActivity.this, 0, new Intent().setAction(Intent.ACTION_VIEW), 0);
         Notification notify= new Notification.Builder(BaiDuMapActivity.this)
                 .setSmallIcon(R.drawable.head_image)
                 .setLargeIcon(largeIcon)
                 .setTicker( "您有新短消息，请注意查收！")
                 .setContentTitle("Notification Title")
                 .setContentText("This is the notification message")
                 .setContentIntent(pendingIntent).setNumber(1).getNotification();
         notify.flags |= Notification.FLAG_AUTO_CANCEL; // FL
         manager.notify(1,notify);
     }
 });

二.问题

没有notification通知显示。

三.解决

1.请设置icon

2.如果API是16请将getNotification()换成build()，可参考：http://blog.csdn.net/loongggdroid/article/details/17616509
