title: How to check if Android Permission is actually being used?
body: <p><br />
  I am maintaining one existing (very-huge, very-sensitive) Android Application. <br />
  The other day, I have received an email from my client that, the Application might be declaring the Permissions that are not actively being used.</p>
  
  <p>For example, they wants me to remove "WRITE_EXTERNAL_STORAGE" permission.<br />
  I have removed it and compiled it and run the App. There is NO error at all. <br />
  But, just because of that, I don't think I can assume that permission is not actively being used at all.</p>
  
  <p>My question is <strong>"Is there anyway I can easily and simply check the permission if it is actively being used ?"</strong></p>
  
  <p>Frankly, I don't want to go through every little detail aspect of that application just to fine out the permission is required or not.<br />
  I just don't have time.</p>
  
  <p>My goal is check if the permission is actively being used. If not, remove the permission.<br />
  Hope there is an less-time consuming way for that.</p>
  
  <p>Regards</p>
