title: change lockscreen settings on a particular time
body: <p>The concept of my personal app is:</p>
  
  <p>I can set (like the alarm app) everyday a timespan for example: every monday from 13:00 until 16:00 hour my lockscreen is enabled.</p>
  
  <p>This is because I don't like the lockscreen after my workhours but I like it when I'm on my work. </p>
  
  <p>Now I did some research and you need to do this with broadcastreceivers and the AlarmManager so the app doesn't run the whole day (correct me when I'm wrong).</p>
  
  <p>What I don't find in the developer guide is how to change the lockscreen settings. Some people on the internet say you need a rooted phone, but I really don't like the rooted part. Is there any way to solve this problem without a rooted phone?</p>
