设备使用信息统计(API9)

场景介绍

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（app 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。

接口说明

注册相关接口包导入：

import usageStatistics from '@ohos.resourceschedule.usageStatistics';

开发步骤

获取设备使用信息之前，需要检查是否已经配置请求相应的权限。系统提供的设备使用信息统计的权限是ohos.permission.BUNDLE_ACTIVE_INFO 具体配置方式请参考权限申请声明

通过指定起始和结束时间查询所有应用的事件集合，需要配置ohos.permission.BUNDLE_ACTIVE_INFO权限。

解除应用分组监听回调，需要配置ohos.permission.BUNDLE_ACTIVE_INFO权限。

import usageStatistics from '@ohos.resourceschedule.usageStatistics'

// promise
try{
    usageStatistics.unregisterAppGroupCallBack().then( () => {
        console.log('BUNDLE_ACTIVE unregisterAppGroupCallBack promise succeeded.');
    }).catch( err => {
        console.log('BUNDLE_ACTIVE unregisterAppGroupCallBack promise failed. code is: ' + err.code + ',message is: ' + err.message);
    });
} catch (error) {
    console.log('BUNDLE_ACTIVE unregisterAppGroupCallBack throw error, code is: ' + error.code + ',message is: ' + error.message);
}

// callback
try{
    usageStatistics.unregisterAppGroupCallBack(err => {
        if(err) {
            console.log('BUNDLE_ACTIVE unregisterAppGroupCallBack callback failed. code is: ' + err.code + ',message is: ' + err.message);
        } else {
            console.log('BUNDLE_ACTIVE unregisterAppGroupCallBack callback success.');
        }
    });
} catch (error) {
    console.log('BUNDLE_ACTIVE unregisterAppGroupCallBack throw error, code is: ' + error.code + ',message is: ' + error.message);
}
