For those stumbling upon this question, here's a solution: In your project.properties, change target=android-x where x < 11 to some x >= 11 e.g target=android-14, because holo was introduced first in android-11 (Honeycomb).

EDIT:

Correction, x>=14 for android:Theme.Holo.Light.DarkActionBar to work.

For error number 2,3 and 4. In your styles.xml file remove the parent="android:Theme", i used in following way

styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <style name="CustomWindowTitleBackground">

    </style>


    <style name="MyTheme" parent="android:Theme">
        <item name="android:windowTitleSize">65dip</item>
        <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item>
    </style>
</resources>

May i hope this will be solve your First Error. Incase your first error wont clear means, just clean the your application and then run it.

when you add a resource to the project you have to update the XML Files associated with it. it will be in a folder probably named res in that folder will be several other folders called drawable layout and values they have XML Files inside them that need to be updated when you ad a resource such as a picture or a string to your project.

I might have the folders wrong, it has been a while since I programmed in Android.

Clean your project: Project->Clean

Also, make sure you did not import "android.R". Eclipse tends to add this sometimes when you manage the imports.
