Holo theme for button

Question

I am using this Code in style.xml file to apply to all Button in the App as i dont want to apply the whole Holo Theme :

 <style name="MyTheme" parent="@android:style/Theme.Black" >
 <item name="android:buttonStyle">@style/Custombutton</item>
 </style>

<style name="Custombutton" parent="Widget.Button" >
    <item name="android:background">@android:drawable/btn_default_holo_dark</item>
    <item name="android:textAppearance">?android:attr/textAppearanceMedium</item>
    <item name="android:textColor">#FFFFFF</item>
</style>

 </resources>

This Code Generate R.java errors, i am sure the error come from this code because when i remove it i have no error,

What is wrong ?

Thanks

Problem Solved, Replaced this :

 <item name="android:background">@android:drawable/btn_default_holo_dark</item>

By This :

 <item name="android:background">@drawable/btn_default_holo_dark</item>

I have the btn_default_holo_dark.png in my Drawable Folder
