title: How to retrieve data from UsageStats found in Android Settings?
body: <p>I am using API 19. For my app that i am building, i need to obtain the usage pattern of each app on my device (i.e. hwo many times have you used since installation...and how many times you open it)
  I cam across this feature called UsageStats provided in my phone under the android settings at location com.android.settings/.UsageStats 
  Now i need to retrieve those data to my application for analysis by my own-app,</p>
  
  <p>I referred various contents from satckoverflow (sorry..i dont have API 21) but they were not as informative.
