Possible overdraw: Root element paints background

To optimize your apps performance (avoid overdraw), you can do the following:

• declare a theme in res/values/styles.xml

  <style name="MyTheme" parent="android:Theme">
      <item name="android:background">@drawable/main</item>
      <item name="android:windowNoTitle">true</item>
      <item name="android:windowFullscreen">true</item>
  </style>
  

• change the Manifest:

  <application
      android:icon="@drawable/ic_logo"
      android:label="@string/app_name"
      android:theme="@style/MyTheme" >
  

• remove the background declaration in “My xml”
