Notification通知未显示

事情：html

今天练练手，搞搞android里面的通知Notification。搞了很久通知一直发不出。android

解决：ui

新SDK通知，使用了NotificationCompat.Builder类，建立代码以下：spa

NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext());
		builder.setContentTitle("title");
		builder.setContentText("content text");
		builder.setContentIntent(contentIntent);
		builder.setSmallIcon(R.drawable.ic_launcher);
