title: How to apply Android Theme.DeviceDefault customization across all applications?
body: <p>I am new to Android UI customization. I need to modify few actionMode and actionBar resources of Theme.Holo and Theme.Holo.Light and I need changes to be reflected in all apps (including base apps like People, Email, Phone, Mms). I am using android 4.0.4 sources.</p>
  
  <p>From <a href="http://android-developers.blogspot.in/2012/01/holo-everywhere.html" rel="nofollow">http://android-developers.blogspot.in/2012/01/holo-everywhere.html</a>, I understand that themes_device_defaults.xml is the place to customize the themes.</p>
  
  <p>But after trying for some time, i realized that all base apps (e.g. Contacts) activities define their theme style based on Theme.Holo or Theme.Holo.Light.</p>
  
  <p>Shouldn't all base apps activities uses Themes  with parent Theme.DeviceDefault.Light or Theme.DeviceDefault to support customization via themes_device_default.xml. </p>
  
  <p>Am i missing something ? Is there any way to customize a theme which gets applied to all apps w/o changing every app's  res/style.xml</p>
  
  <p>Thanks &amp; regards,
  Anuj</p>
