Android中关于setLatestEventInfo()过时以及构建Notification的解决方法

官方说法：
public Notification getNotification () Added in API level 11
This method was deprecated in API level 16. Use build() instead. 
在API 11中，通过builder.getNotification()获取Notification对象已经过时了，替代方法是使用builder.builder();
 
Creating a Notification //创建一个Notification
You specify the UI information and actions for a notification in a NotificationCompat.Builder object. To create the notification itself, you callNotificationCompat.Builder.build(), which returns a Notification object containing your specifications. To issue the notification, you pass the Notification object to thesystem by calling NotificationManager.notify().
通过NotificationCompat.Builder.build()创建一个notification对象，它返回一个你已经创建的notification对象，通过使用 NotificationManager.notify()来进行系统通知


public Notification build () 
Added in API level 16 Combine all of the options that have been set and return a newNotification object.
Notification build ()是在API 16中才加入的，它包括了Notification所需要的所有选项，并返回一个notification对象
 
Required notification contents 
A Notification object must contain the following: 
A small icon, set by setSmallIcon() 
A title, set by setContentTitle() 
Detail text, set by setContentText()
一个Notification对象需要包括以下内容：
一个小图标：builder.setSmallIcon(R.drawable.ic_launcher);
一个标题：builder.setContentTitle("通知的标题");

一个内容：builder.setContentText("这是通知的内容");

具体如何创建：

NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification.Builder builder = new Notification.Builder(
MainActivity.this);
builder.setContentTitle("通知的标题");
builder.setContentText("这是通知的内容");
builder.setSmallIcon(R.drawable.ic_launcher);
Notification notification = builder.build();
manager.notify(1, notification);
