使用noficaton报错如下：IllegalArgumentException: contentView required！
1 nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE); 2 long when = System.currentTimeMillis(); 3 ntf = new Notification(ic,tickerText,when); 4 PendingIntent pt = PendingIntent.getActivity(this, 0, null, 0); 5 //ntf.setLatestEventInfo(getApplicationContext(), "QQ音乐", "正在下载...", pt); 6 nm.notify(R.string.app_name, ntf);
报错原因找到，是因为没有加注释这行，nofify之前，一定要让NotificationManager.setLatestEventInfo();
