SystemServices

Since AndroidAnnotations 1.0

Standard Android System Service injection

Retrieving Android System Services requires remembering the name of the constant, and casting the retrieved object.

获取Android System Service需要想起常量名，并且强制转换获得的对象。

notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

The @SystemService annotation indicates that an activity field should be injected with the corresponding Android System service .

@SystemService 注解表明activity 字段应该由相应的Android System service 注入。

It is the same as calling the Context.getSystemService() method.

它和调用 Context.getSystemService() 方法起到了相同的作用。

Usage example:用法：

@EActivity
public class MyActivity extends Activity {
        @SystemServiceNotificationManager notificationManager;}
