title: build android app using intellij idea cannot find theme AppCompat.Light
body: <p>Now I am trying to build this android app using this <a href="http://developer.android.com/intl/zh-cn/training/basics/actionbar/styling.html" rel="nofollow">tutorial</a> . but when I add the example code below I got an error.</p>
  
  <pre><code>&lt;activity android:name="MyActivity"
        android:label="@string/app_name"
        android:theme="@style/Theme.AppCompat.Light"&gt;
  </code></pre>
  
  <p>the error is :</p>
  
  <pre><code>AndroidManifest.xml:10: error: Error: No resource found that matches the given
  name (at 'theme' with value '@style/Theme.AppCompat.Light').
  </code></pre>
  
  <p>I have tried many post on the internet but I didn`t find solutions about using intellij idea.</p>
  
  <p>and all my code is here, but I think this is not the problem it must be something I forgot to config using idea :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
