Remarks
Provides access to device usage history and statistics. Usage data is aggregated into time intervals: days, weeks, months, and years. <p /> When requesting usage data since a particular time, the request might look something like this:
PAST REQUEST_TIME TODAY FUTURE
————————————————————————————||———————————————————————————¦-----------------------|
YEAR || ¦ |
————————————————————————————||———————————————————————————¦-----------------------|
MONTH | || MONTH ¦ |
——————————————————|—————————||———————————————————————————¦-----------------------|
| WEEK | WEEK|| | WEEK | WE¦EK | WEEK |
————————————————————————————||———————————————————|———————¦-----------------------|
|| |DAY|DAY|DAY|DAY¦DAY|DAY|DAY|DAY|DAY|DAY|
————————————————————————————||———————————————————————————¦-----------------------|
A request for data in the middle of a time interval will include that interval. <p/> <b>NOTE:</b> Most methods on this API require the permission android.permission.PACKAGE_USAGE_STATS. However, declaring the permission implies intention to use the API and the user of the device still needs to grant permission through the Settings application. See android.provider.Settings#ACTION_USAGE_ACCESS_SETTINGS. Methods which only return the information for the calling package do not require this permission. E.g. #getAppStandbyBucket() and #queryEventsForSelf(long, long).
