title: How to color the background of the application in android
body: <p>I added a color folder, with this xml file:</p>
  
  <pre><code>    &lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;item
    xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;color name="orange"&gt;#FF9912&lt;/color&gt;
  &lt;/item&gt;
  </code></pre>
  
  <p>But when I put as the value in the screen_display.xml that i created in the values folder. It gives me a mistake:</p>
  
  <pre><code>        &lt;?xml version="1.0" encoding="utf-8"?&gt;
      &lt;resources&gt;
          &lt;style name="MyTheme.Background" parent="@android:style/Theme"&gt;
            &lt;item name="android:windowNoTitle"&gt; true&lt;/item&gt;
             &lt;item name="android:windowFullscreen"&gt;true&lt;/item&gt;
             &lt;item name="android:windowBackground"&gt;@colors/color/orange&lt;/item&gt;
          &lt;/style&gt; 
      &lt;/resources&gt;
  
  UPDATE
      &lt;activity android:name=".EasyLearningActivity"
                    android:launchMode="singleTask"
                    android:alwaysRetainTaskState="true"
                    android:screenOrientation="portrait"
                    android:configChanges="orientation|keyboardHidden"
                    android:theme="MyTheme.Background"...shows mistake, saying that Strying type inst allowed :(
                    &gt;
