关于notification的使用失误

关于notification的使用出错

Thread downloadThread = new Thread() {
			@Override
			public void run() {
				int flagSong = download.downloadFile(songFile);
				download.setUrl_path(urlLrc);
				int flagLrc = download.downloadFile(lrcFile);
				int flag = flagSong + flagLrc;
				Notification notification;
				if (flag == 2) {
					notification = new Notification(android.R.id.icon2,
							"download", java.lang.System.currentTimeMillis());
					notification.setLatestEventInfo(RemoteMp3Activity.this,
							"下载", "下载完成", null);
					notification.flags = Notification.FLAG_AUTO_CANCEL;
					notification.defaults = Notification.DEFAULT_SOUND;
				} else {
					notification = new Notification(
							android.R.drawable.arrow_up_float, "download",
							java.lang.System.currentTimeMillis());
					Intent notificationIntent = new Intent(
							RemoteMp3Activity.this, MainActivity.class);
					PendingIntent pendingIntent = PendingIntent.getActivity(
							RemoteMp3Activity.this, 0, notificationIntent, 0);
					notification.setLatestEventInfo(RemoteMp3Activity.this,
							"下载", "下载未完成", pendingIntent);
					notification.flags = Notification.FLAG_AUTO_CANCEL;
					notification.defaults = Notification.DEFAULT_SOUND;
				}
				manager.notify(SONG_DOWNLOAD, notification);
			}
		};

代码
------解决方案--------------------
if?(flag?==?2)?{   里面的contentIntent为空  看log应该是这个原因
LZ是2.3下的代码吧  设置contentIntent吧   不然报错的  4.0可以为空
