title: android studio change theme to holo crashes app
body: <p>I have an app I was working on.   We wanted to upgrade the minSDK from Froyo to IceCream Sandwich (14) so we could use some of the newer features including the Holo Dark theme.</p>
  
  <p>On StackOverflow we found steps for editing the build.gradle (Module: app) file and changed the minSDK to 14.   We resync'd as requested.  Then rebuilt the app.  All compiled fine and ran on our connected device which is running 4.4.4</p>
  
  <p>I then went to the styles.xml file and changed the AppTheme accordingly.</p>
  
  <pre><code> &lt;style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"&gt;
  </code></pre>
  
  <p>to</p>
  
  <pre><code>   &lt;style name="AppTheme" parent="android:Theme.Holo"&gt;
  </code></pre>
  
  <p>also as recommended here.    </p>
  
  <p>I rebuild the app and it compiles fine.  When it attempts to run on our connected device, I get a "The Application has Stopped" immediately.</p>
  
  <p>I looked in the LogCat (per a Comment) and once I figured out what I was looking at, I found this line:</p>
  
  <p><code>Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.</code> </p>
  
  <p>Not sure what that means.</p>
  
  <p>Am I missing something either on the "SDK" change or on the Theme?</p>
  
  <p>Thanks
  Pete</p>
