title: How to update to the latest version of Android Support Library in Eclipse?
body: <p>I'm trying to import a project into Eclipse and I'm getting the errors:</p>
  
  <blockquote>
    <p>The import android.support.v7.widget.Toolbar cannot be resolved The
    project was not built since its build path is incomplete. Cannot find
    the class file for
    android.support.v4.app.ActionBarDrawerToggle$DelegateProvider</p>
  </blockquote>
  
  <p>I found this answer from other question -<a href="https://stackoverflow.com/questions/33711139/why-the-import-android-support-v7-widget-toolbar-cannot-be-resolved-in-my-projec">Why the import android.support.v7.widget.Toolbar cannot be resolved in my project</a>
  So it seems to be a problem with the Android Support Library. But when I try to update mine it only has version 20 available. The other answer said they were able to upgrade their version but I don't seem to have that option. How to do get the latest version of the Support Library?</p>
