02-24 10:05:24.731: E/AndroidRuntime(1577): java.lang.NoSuchMethodError: android.app.Notification$Builder.build

错误原因：（详见代码第51行）

Notification.Builder（context）.build();方法不存在

解决方案：（详见代码第51行）

将Notification.Builder改为 NotificationCompat.Builder（import android.support.v4.app.NotificationCompat;）

package com.zml.notification;import android.annotation.SuppressLint;import android.app.Activity;import android.app.Notification;import android.app.NotificationManager;import android.app.PendingIntent;import android.content.Intent;import android.os.Bundle;import android.support.v4.app.NotificationCompat;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import com.zml.practice.R;/** * @author 郑明亮 * @Time：2016-2-24 下午5:22:49 * @version 1.0 */public class NotificationActivity extends Activity implements OnClickListener {Button bt_open, bt_cancle;NotificationManager notificationManager;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.activity_notification);bt_cancle = (Button) findViewById(R.id.bt_cancle_notifu);bt_open = (Button) findViewById(R.id.bt_open_notify);bt_cancle.setOnClickListener(this);bt_open.setOnClickListener(this);notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);}@SuppressLint("NewApi")@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.bt_open_notify:Intent intent = new Intent(NotificationActivity.this,OtherActivity.class);PendingIntent pIntent = PendingIntent.getActivity(NotificationActivity.this, 0, intent, 0);//注意，这里不是 Notification.Builder,而是NotificationCompat.BuilderNotification notification = new NotificationCompat.Builder(NotificationActivity.this).setAutoCancel(true)// 显示在通知栏的通知提示信息.setTicker("Congratulation！")// 通知标题.setContentTitle("您有一条新通知")// 通知内容.setContentText("您中了100万，请速到这来领取！")// 设置图标.setSmallIcon(R.drawable.ic_launcher)// 使用系统默认声音，震动，led灯等设置.setDefaults(Notification.DEFAULT_ALL).setWhen(System.currentTimeMillis())// 加上点击后的意图.setContentIntent(pIntent).build();notificationManager.notify(0x001, notification);break;case R.id.bt_cancle_notifu:notificationManager.cancel(0x001);break;default:break;}}}
