You can use this:

String packageName = "";
String className = "";

UsageStatsManager usageStatsManager = (UsageStatsManager) this.getSystemService(Context.USAGE_STATS_SERVICE);

if (usageStatsManager != null)
{
   UsageEvents queryEvents = usageStatsManager.queryEvents(System.currentTimeMillis() - 10000, System.currentTimeMillis());

   if (queryEvents != null) 
   {
      UsageEvents.Event event = new UsageEvents.Event();

      while (queryEvents.hasNextEvent()) 
      {
          UsageEvents.Event eventAux = new UsageEvents.Event();
          queryEvents2.getNextEvent(eventAux);

          if (eventAux.getEventType() == UsageEvents.Event.MOVE_TO_FOREGROUND)
          {
              event = eventAux;
          }
      }

      packageName = event.getPackageName();
      className = event.getClassName();
   }
}

You need the android.permission.PACKAGE_USAGE_STATS, which is a system-level permission and will not be granted to third-party apps. However, declaring the permission implies intention to use the API and the user of the device can grant permission through the Settings application.

Or you can do:

pm grant com.your.package android.permission.PACKAGE_USAGE_STATS
