/***
 * @Description: 前台服务
 * channelId必须要一致，否则会报 android.app.RemoteServiceException: Bad notification for startForeground 错误
 * 8.0之上一定要使用 NotificationChannel 适配下才行
 * 步骤
 * 1.通过 “通知服务” 创建 NotificationChannel
 * 2.通过 Notification.Builder 构造器 创建 Notification
 * 3.通过 startForeground 开启服务
 * 4.高于9.0的版本 manifest需要增加  <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
 *
 * 在onCreate中创建一个广播接收器，试试能不能接收到 开单或者预约结束后的通知
