title: No version of Android SDK Build-Tools installed
body: <p>My Gradle project sync is failing in Android Studio and it is showing the following errors:</p>
  
  <p><a href="https://i.stack.imgur.com/iF9Gt.png" rel="nofollow noreferrer">Gradle project sync failed</a></p>
  
  <p><a href="https://i.stack.imgur.com/fDP2r.png" rel="nofollow noreferrer">Failed to find target with hash string 'android-26' in: C\Users\...</a></p>
  
  <p>To fix this I tried to install android API 26 but when I did I realized that no version of the Android SDK Build-Tools was installed:</p>
  
  <p><a href="https://i.stack.imgur.com/sDdgh.png" rel="nofollow noreferrer">SDK Tools</a></p>
  
  <p>When trying to update the Build-Tools through the SDK manager I got the following error:</p>
  
  <p>To install:
  - Android SDK Build-Tools 27.0.1 (build-tools;27.0.1)
  Preparing "Install Android SDK Build-Tools 27.0.1 (revision: 27.0.1)".
  Failed packages:
  - Android SDK Build-Tools 27.0.1 (build-tools;27.0.1)</p>
  
  <p>Does anyone have any advice on how to get past this issue?</p>
