title: Mono for Android: Application wide theme
body: <p>I'm new to Mono for Android (using MonoDevelop) and Android development in general. I want to create a application wide theme. This theme only has to set the background color of all EditText fields gray (just to test the functionality).</p>
  
  <p>In the Resources/values folder I created 2 files:</p>
  
  <p>Styles.xml</p>
  
  <pre><code>&lt;resources&gt;
  &lt;style name="tstEditText" parent="android:style/Widget.EditText"&gt;
      &lt;item name="android:background"&gt;#cccccc&lt;/item&gt;
  &lt;/style&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>Themes.xml</p>
  
  <pre><code>&lt;resources&gt;
  &lt;style name="MyApplicationTheme" parent="android:Theme"&gt;    
      &lt;item name="android:editTextStyle"&gt;@style/txtEditText&lt;/item&gt;
  &lt;/style&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>After that I modified the ApplicationManifest.xml</p>
  
  <pre><code>&lt;application android:label="MyApplication" android:theme="MyApplicationTheme"&gt;&lt;/application&gt;
  </code></pre>
  
  <p>When I try to build the code I get the following error message: "<strong>Error: String types not allowed (at 'theme' with value 'MyApplicationTheme').</strong>" The error is thrown on the first activity node in the AndroidManifest.xml that is generated on build by MonoDevelop.</p>
  
  <p>Apparently I'm missing something, but I have no clue...
  Thanks in advance for your help!</p>
