关于《第一行代码》中安卓通知的修改

最近在学安卓，在看郭霖大神的第一行代码，其中通知章节中用到如下代码：

Notification notification = new Notification(R.drawable.strawberry,"this is ticker text",System.currentTimeMillis());

在android studio中显示该方法已被废弃，所以自己找到如下替换方案，方便新手学习：

NotificationManager manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(MainActivity.this).setSmallIcon(R.drawable.strawberry)
.setContentTitle("this is title")
.setContentText("this is text");
mBuilder.setTicker("this is the trick");
//构建一个Intent
Intent resultIntent = new Intent(this,NotificationActivity.class);
//封装一个Intent
PendingIntent resultPendingIntent = PendingIntent.getActivity( this, 0, resultIntent,
PendingIntent.FLAG_CANCEL_CURRENT);
// 设置通知主题的意图
mBuilder.setContentIntent(resultPendingIntent);
manager.notify(1,mBuilder.build());
