title: Strange Lint Warning - Unexpected text found in layout file: ""
body: <p>I've got the following selector defined in button_selector.xml</p>
  
  <pre><code>    &lt;?xml version="1.0" encoding="utf-8"?&gt;
      &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
         &lt;item android:state_pressed="true" 
             android:state_enabled="true"
             android:drawable="@drawable/button_settlement_background_pressed" /&gt;
         &lt;item android:state_enabled="true"
             android:drawable="@drawable/button_settlement_background_normal" /&gt;
         &lt;item android:state_enabled="false"
             android:drawable="@drawable/button_settlement_background_disabled" /&gt;
         &lt;/selector&gt;
  </code></pre>
  
  <p>When I run lint I get the following warning: Unexpected text found in layout file: "". It says it's happening at line 4 in "drawable". All of the referenced drawables exist in /res/drawable.</p>
  
  <p>Does anyone know what could be causing this? I can ignore the warning but I'd rather fix it if possible.</p>
  
  <p>Also, I get warnings for unused strings and icons when they're only referenced in AndroidManifest.xml. Is there a way to fix those instead of ignoring them?</p>
