title: Android Studio: Android Device Monitor not showing my device
body: <p>My real device is <strong>Sony Xperia c6502</strong> with android version 4.3
  I'm sure I connect it to my computer and I turn <strong>Developer options/ USB debugging</strong> on</p>
  
  <p>In SDK manager, Google USB driver is already installed.</p>

  <p>I downloaded Xperia Z Driver from this page:<a href="http://developer.sonymobile.com/downloads/drivers/" rel="noreferrer">http://developer.sonymobile.com/downloads/drivers/</a>
  But I don't know how to use it

  <p>My device is not shown in Android Device Monitor and thus I can't run app test on my phone.</p>
  
  <p>How to let my Android Studio catch my phone?</p>
