异常NoSuchMethodError: android.app.Notification$Builder.build解决方案

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;）
