title: Flutter does not find android sdk
body: <p>I just tried intalling flutter and since I already had android studio and the android sdk installed I just followed the installation of flutter. Here is my problem: When I run</p>
  
  <pre><code>flutter doctor
  </code></pre>
  
  <p>It tells me </p>
  
  <pre><code>  [√] Flutter (Channel beta, v0.1.5, on Microsoft Windows [Version 10.0.16299.248], locale en-US)
      • Flutter version 0.1.5 at C:\Users\Name\git\flutter
      • Framework revision 3ea4d06340 (2 weeks ago), 2018-02-22 11:12:39 -0800

      X ANDROID_HOME = C:\Users\Name\AppData\Local\Android\sdk\Android
        but Android SDK not found at this location.
  
  [√] Android Studio (version 3.0)
      • Android Studio at C:\Program Files\Android\Android Studio
      • Java version OpenJDK Runtime Environment (build 1.8.0_152-release-915-b01)
  </code></pre>
  
  <p>Which tells me that flutter is not finding my Android sdk (even though it is the path that android studio uses aswell - and android studio is working fine)</p>
  
  <p>I already tried reinstalling the sdk but it did not work.</p>
  
  <p>Im very thankful for any help with this.</p>
