Question

I see a lot a similar questions R.java can’t compile , No resource found that matches @android:style/ “just after SDK & ADT update” leading to existing projects can’t compile
The R.java file cannot be compiled. I find out the errors come from referencing

<style name="Theme.Wallpaper" parent="android:style/Theme.Wallpaper" >
    <item name="android:colorForeground">#fff</item>
</style>

What is happening is that some styles, like Theme.Wallpaper are not public. You should not extend from them anymore.

Some suggest to revert to platform_tools_r05

If you wish to reuse a style that is private, you should copy the
content of that style into your own instead of extending it.

Ok so Where do I find the content of the (private) style ?
Seriously, after an update I don’t have time to correct platform mistakes when the project code worked right.

Answer 1

<!-- Default theme for windows that want to have the user's selected
     wallpaper appear behind them.  -->
<style name="Theme.Wallpaper">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:colorBackgroundCacheHint">@null</item>
    <item name="android:windowShowWallpaper">true</item>
</style>

Looks like you want to use the above code from the Android source and create your own theme based it.
