"Go" "Android" Android different version under Notification creation method

When using the new Notification (int icon, charsequence tickertext, long when) constructor, Eclipse prompts: "The constructor Notification (int, Cha Rsequence, long) is deprecated "

/*** Constructs a Notification object with the information needed to* has a status bar icon without the standard Expande D view.**@paramicon The resource ID of the the icon to put in the status bar.*@paramTickertext the text that flows by in the status bar when the notification first* activates.*@paramWhen the time-to-show in the Time field. In the system.currenttimemillis* timebase.**@deprecatedUse {@linkBuilder} instead.*/@Deprecated PublicNotification (inticon, Charsequence Tickertext,LongWhen ) { This. Icon =icon;  This. Tickertext =Tickertext;  This. When =When ;}

There are some differences in the use of notification under different versions, involving the use of builder. Now summarize the following and hope to help the programmers in the future.

Below API level 11, which is Android 2.3.3, the Setlatesteventinfo () function is the only implementation method. The previous related property settings are no longer mentioned here, there are many online data.

Intent  New Intent (this, mainactivity);   = pendingintent.getactivity (context, 0, intent, pendingintent.flag_one_shot);  Notification.setlatesteventinfo (context, title, message, pendingintent);          

Higher than API level 11, a system that is lower than the API level (Android 4.1.2) version can use Notification.builder to construct functions. But use GetNotification () to make the notification implementation. At this point, the previous version of the notification set in the Flags,icon and other properties are invalid, to be set in the builder.

New Notification.builder (context).              Setautocancel (true)              . Setcontenttitle ("title" )              . Setcontenttext ("describe")              . Setcontentintent (pendingintent).              Setsmallicon ( R.drawable.ic_launcher)              . Setwhen (System.currenttimemillis ())              . setongoing (true);  Notification=builder.getnotification ();

Higher than the API level 16 version, you can use the builder and build () function to match the convenience of notification.

New Notification.builder (context).             Setautocancel (true)             . Setcontenttitle ("title" )             . Setcontenttext ("describe")             . Setcontentintent (pendingintent).             Setsmallicon ( R.drawable.ic_launcher).             Setwhen (System.currenttimemillis ())             . Build ();

"Note points":
There are many ways to do this when constructing notification, but be aware that
Notification Notification = new Notification ();
This construction method, must add Notification.icon this setting, otherwise, although the program will not error, but will not be effective.

Problem:

Using the Setlatesteventinfo () method under notification, Eclipse prompts: "The method Setlatesteventinfo (Context, String, String, pendingintent) is undefined for the type Notification "!

The Setlatesteventinfo method has been removed.
