How to use UsageStatsManager?

by

I think the documentation was just short hand for the Calendar stuff. I don’t think it actually works with just 2014; however I can be wrong.

In order to access the actually list of UsageStats, you would need to create a Calendar object with the correct month,day, and year. Exactly how MRK said in the other answer. I copied and corrected the errors in MRK’s code so anyone who sees it in the future can see it.

Calendar beginCal = Calendar.getInstance();
beginCal.set(Calendar.DATE, 1);
beginCal.set(Calendar.MONTH, 0);
beginCal.set(Calendar.YEAR, 2012);

Calendar endCal = Calendar.getInstance();
endCal.set(Calendar.DATE, 1);
endCal.set(Calendar.MONTH, 0);
endCal.set(Calendar.YEAR, 2014);

final List<UsageStats> queryUsageStats=usageStatsManager.queryUsageStats(UsageStatsManager.INTERVAL_YEARLY, beginCal.getTimeInMillis(), endCal.getTimeInMillis());

-Credit MRK; corrected by me (he accidentally just put cal instead of beginCal and endCal)

The code for the usage access settings is below. 🙂

Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);
startActivity(intent);
