title: Can I get Google Play Licensing Library Package back once deleted from SDK Manager?
body: <p>I want to implement App Licensing in my app. As we know, for that we need to install "Google Play Licensing Library" from the Extras Folder of SDK Manager. 
  But, i was unable to import the Library Project and the Sample Project, so i deleted that package thinking that re-installation would fix that. </p>
  
  <p>Now My SDK Manager is not showing me that package.</p>
  
  <p>Is there any way to install it back again?</p>
  
  <p>OR i have to get a new SDK.</p>
  
  <p>Please Help.</p>
