UsageStatsManager 使用统计
目录
UsageStatsManager 使用总结
Provides access to device usage history and statistics. Usage data is aggregated into 汇总成 time intervals 时间间隔: days, weeks, months, and years.
A request for data in the middle of a time interval 间隔 will include that interval.
NOTE: Most methods on this API require the permission
android.permission.PACKAGE_USAGE_STATS. However, declaring 声明 the permission implies 暗示 intention 意图 to use the API and the user of the device still needs to grant permission through theSettingsapplication. Methods which only return the information for thecalling packagedo not require this permission. E.g.getAppStandbyBucket()andqueryEventsForSelf().
应用使用统计信息
查询应用使用统计信息，包括：应用的前台使用时长，应用首次启动的时间，应用启动次数，应用最近一次使用的时间等
queryUsageStats
List<UsageStats> queryUsageStats(int intervalType, long beginTime, long endTime)
Gets application usage stats for the given time range, aggregated by the specified interval.
The returned list will contain one or more UsageStats objects for each package, with usage data that covers at least the given time range 至少覆盖给定的时间范围.
Note: The begin and end times of the time range may be
expandedto the nearest whole interval period.
queryAndAggregateUsageStats
Map<String, UsageStats> queryAndAggregateUsageStats(long beginTime, long endTime)
A convenience method that queries for all stats in the given range, merges the resulting data, and keys it by package name.
其实就是逐个遍历 queryUsageStats 返回的结果，按照包名进行整合，得出多条记录的合并结果后再封装起来。
UsageStats
Contains usage statistics for an app package for a specific time range.
常用方法：
- long getFirstTimeStamp()：Get the
beginningof the time range this UsageStats represents, measured in milliseconds since the epoch纪元. 获取此UsageStats表示的时间范围的开始。 - long getLastTimeStamp()：Get the
endof the time range this UsageStats represents, ... - long getLastTimeUsed()：Get the last time this package's
activity was used, ... - long getTotalTimeInForeground()：Get the total time this package
spentin the foreground, ...
API 29 新增方法：
- long getLastTimeVisible()：Get the last time this package's
activity is visiblein the UI, ... - long getLastTimeForegroundServiceUsed()：Get the last time this package's
foreground service was used, ... - long getTotalTimeVisible()：Get the total time this package's activity is
visiblein the UI, ... - long getTotalTimeForegroundServiceUsed()：Get the total time this package's
foreground services are started, ...
时间间隔类型
- UsageStatsManager.INTERVAL_DAILY ：天存储级别的数据
- UsageStatsManager.INTERVAL_WEEKLY ：星期存储级别的数据
- UsageStatsManager.INTERVAL_MONTHLY ：月存储级别的数据
- UsageStatsManager.INTERVAL_YEARLY ：年存储级别的数据
- UsageStatsManager.INTERVAL_BEST ：根据给定时间范围选取最佳时间间隔类型

设备状态事件统计
事件包括：锁屏事件、切换前台事件、切换到后台事件、屏幕交互状态事件、屏幕非交互状态事件等
queryEventStats
List<EventStats> queryEventStats(int intervalType, long beginTime, long endTime) //API 28添加
Gets aggregated 汇总 event stats for the given time range, aggregated by the specified interval.
The returned list will contain a EventStats object for each event type that is being aggregated and has data for an interval that is a subset of the time range given.
返回的列表将为每个正在汇总的事件类型包含一个EventStats对象，并具有间隔时间的数据，该间隔是给定时间范围的子集。
EventStats
Contains usage statistics for an event type for a specific time range.
常用方法：
- void add(EventStats right)：Add the statistics from the right EventStats to the left. The event type for both UsageStats objects must be the same. 系统服务调用的方法
- int getCount()：Return the number of times that this event occurred over the interval.
- int getEventType()：Return the type of event this is usage for. May be one of the event constants in
UsageEvents.Event. - long getFirstTimeStamp()：Get the beginning of the time range this EventStats represents, measured in milliseconds since the epoch.
- long getLastEventTime()：Get the last time this event triggered, measured in milliseconds since the epoch.
- long getLastTimeStamp()：Get the end of the time range this EventStats represents, measured in milliseconds since the epoch.
- long getTotalTime()：Get the total time this event was active, measured in milliseconds.
涉及到的四种事件
- UsageEvents.Event.SCREEN_INTERACTIVE = 15：交互状态。An event type denoting 表示 that the screen has gone in to an interactive 交互 state (turned on for full user interaction, not ambient display 环境显示 or other non-interactive state). 表示屏幕已进入交互状态的事件类型（为完全用户交互而打开，而不是环境显示或其他非交互状态）
- UsageEvents.Event.SCREEN_NON_INTERACTIVE = 16：非交互状态。An event type denoting that the screen has gone in to a non-interactive state (completely turned off or turned on only in a non-interactive state like ambient display). 表示屏幕已进入非交互状态的事件类型（完全关闭或仅在非交互状态（如环境显示）中完全打开）。
- UsageEvents.Event.KEYGUARD_SHOWN = 17：锁屏。An event type denoting that the screen's keyguard 键盘锁 has been shown, whether or not the screen is off.指示屏幕的键盘锁已经显示，无论屏幕是否关闭。
- UsageEvents.Event.KEYGUARD_HIDDEN = 18：解锁。An event type denoting that the screen's keyguard has been hidden. This typically happens when the user unlocks their phone after turning it on. 表示屏幕的键盘锁已隐藏。 当用户在打开手机后解锁手机时，通常会发生这种情况。

其他方法
List<ConfigurationStats> queryConfigurations(int intervalType, long beginTime, long endTime)
Gets the hardware configurations the device was in for the given time range, aggregated by the specified interval. The results are ordered as in queryUsageStats(int, long, long).
配置信息包括：orientation、uimode、mcc、mnc、navigation、locale、keyboard等
int getAppStandbyBucket()
Returns the current standby bucket of the calling app. The system determines the standby state of the app based on app usage patterns. Standby buckets determine how much an app will be restricted from running background tasks such as jobs and alarms.
boolean isAppInactive(String packageName)
Returns whether the specified app is currently considered inactive. This will be true if the app hasn't been used directly or indirectly for a period of time defined by the system. This could be of the order of several hours or days.
Apps are not considered inactive when the device is charging.
获取指定的应用程序当前是否为非活动状态。无论我怎么测试，返回值都是false！
如何获取该权限
1、在manifest文件中声明该权限
<uses-permission android:name="android.permission.PACKAGE_USAGE_STATS"/>
只有在清单文件中声明了此权限，才能继续后面的操作
2、跳到系统setting应用中打开相应开关，准许应用获取数据
//public static final String ACTION_USAGE_ACCESS_SETTINGS = "android.settings.USAGE_ACCESS_SETTINGS";
startActivity(new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS));
3、判断是否具有此权限
常规的判断权限方式无法获取到准确的 UsageStatsManager 权限是否被赋予，以下方法经验证有效
@TargetApi(Build.VERSION_CODES.M)
public static boolean isGrantedUsagePremission(@NonNull Context context) {
boolean granted;
AppOpsManager appOpsManager = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
int mode = appOpsManager.checkOpNoThrow(AppOpsManager.OPSTR_GET_USAGE_STATS, android.os.Process.myUid(), context.getPackageName());
if (mode == AppOpsManager.MODE_DEFAULT) {
granted = (context.checkCallingOrSelfPermission(android.Manifest.permission.PACKAGE_USAGE_STATS) == PackageManager.PERMISSION_GRANTED);
} else {
granted = (mode == AppOpsManager.MODE_ALLOWED);
}
return granted;
}
