设备使用信息统计

简介

设备使用信息统计,包括app usage/notification usage/system usage等使用统计。例如应用使用信息统计,用于保存和查询应用使用详情(app usage)、事件日志数据(event log)、应用分组(bundle group)情况。 部件缓存的应用记录(使用历史统计和使用事件记录)会在事件上报后30分钟内刷新到数据库持久化保存。

使用说明

设备使用信息统计接口众多,以应用使用详情(app usage)接口为例,介绍接口逻辑。

  • 应用使用统计信息落盘时机
  1. 每隔30分钟触发一次刷新;
  2. 系统时间变更触发一次刷新;
  3. 下一天开始触发一次刷新;
  • 应用查询接口
  1. 根据起止时间查询所有应用的事件集合;
  2. 根据起止时间查询应用的使用时长;
  3. 根据起止时间查询当前应用的事件集合;
  4. 根据interval(日、周、月、年)类型和起止时间查询应用的使用时长;
  5. 查询当前应用的优先级分组;
  6. 判断指定应用当前是否是空闲状态;
  7. 根据起止时间查询系统事件(休眠、唤醒、解锁、锁屏)统计信息;
  8. 根据起止时间查询应用通知次数;
  9. 查询FA使用记录。返回数量最大不超过maxNum设置的值,FA使用记录由近及远排序,maxNum最大为1000,若不填写maxNum参数,则maxNum默认为1000;
  10. 查询当前应用或指定bundlename对应的应用的分组;
